CD artifact sources

In DevOps, an artifact source is a location where the compiled, tested, and ready-to-deploy software artifacts are stored. These artifacts could be container images, compiled binary files, executables, or any other software components that are part of the application.

To add an artifact source, you add a Harness connector to the artifact platform (DockerHub, GCR, Artifactory, etc.) and then add an artifact source to a Harness service that defines the artifact source name, path, tags, and so on.

This topic lists the artifact sources you can use in your Harness services.

Using artifacts in manifests

You have two options when referencing the artifacts you want to deploy:

  • Add an artifact source to the Harness service and reference it using the Harness service artifacts expression <+artifacts.primary.image> in the values YAML file.
  • Hardcode the artifact into the manifests or values YAML file.

Use the artifact expression

Add the image location to Harness as an artifact in the Artifacts section of the service.

This allows you to reference the image in your values YAML files using the Harness expression <+artifacts.primary.image>.

...  
image: <+artifacts.primary.image>
...

You cannot use Harness variables expressions in your Kubernetes object manifest files. You can only use Harness variables expressions in values YAML files, or Kustomize Patch file.

When you select the artifact repo for the artifact, like a Docker Hub repo, you specify the artifact and tag/version to use.

You can select a specific tag/version, use a runtime input so that you are prompted for the tag/version when you run the pipeline, or you can use an Harness variable expression to pass in the tag/version at execution.

Here's an example where a runtime input is used and you select which image version/tag to deploy.

With a Harness artifact, you can template your manifests, detaching them from a hardcoded location. This makes your manifests reusable and dynamic.

Hardcode the artifact

If a Docker image location is hardcoded in your Kubernetes manifest (for example, image: nginx:1.14.2), then you can simply add the manifest to Harness in Manifests and Kubernetes will pull the image during deployment.

When you hardcode the artifact in your manifests, any artifacts added to your Harness service are ignored.

Docker

Use artifacts in any Docker registry

YAML

To use a Docker artifact, you create or use a Harness connector to connect to your Docker repo and then use that connector in your Harness service and reference the artifact to use.

Docker connector YAML

Harness Manager

To add an artifact from a Docker registry, do the following:

  1. In your project, in CD (Deployments), select Services.

  2. Select Manage Services, and then select New Service.

  3. Enter a name for the service and select Save.

  4. Select Configuration.

  5. In Service Definition, select Kubernetes.

  6. In Artifacts, select Add Artifact Source.

  7. In Select Artifact Repository Type, select the registry where your Docker artifact is hosted. For this example, we'll select Docker Registry, and then click Continue.

  8. Select or create a Docker Registry Connector.

  9. Select Continue.

  10. In Artifact Source Name, enter a name that identifies your artifact.

  11. In Image path, enter the name of the artifact you want to deploy, such as library/nginx or jsmtih/privateimage.

    Official images in public repos often need the label library, e.g. library/tomcat.

    Wildcards are not supported.

  12. In Tag, enter or select the Docker image tag for the image.

  1. To specify an image digest, use Digest and the unique identifier for the image you want to use. Specifying an image by tag and digest (rather than tag alone) is useful when you want to deploy an image with a fixed digest/SHA for your service.
note

If an image with the specified tag/digest combination does not exist in the artifact registry, the pipeline will fail.

  1. Select Submit. The Artifact is added to the Service Definition.

Important notes

  • For pulling Docker images from Docker repos, Harness is restricted by the limits of the Docker repo. For example, Docker Hub limits.
  • The maximum number of artifact image tags fetched by Harness that is 10000.

Docker artifact expressions

You can reference artifact properties using the following expressions in a values YAML file or in any Harness setting that supports Harness expressions.

  1. Select Submit.

    The Artifact is added to the Service Definition.

Permissions

For Google Container Registry (GCR), the following roles are required:

  • Storage Object Viewer (roles/storage.objectViewer)
  • Storage Object Admin (roles/storage.objectAdmin)

For more information, go to the GCP documentation about Cloud IAM roles for Cloud Storage.

Ensure the Harness Delegate you have installed can reach storage.cloud.google.com and your GCR registry host name, for example gcr.io.

Use Docker Registry for GCR

If you do not want to use the GCP connector for GCR, you can use the platform-agnostic Docker Registry connector.

Use the following settings:

  • Provider Type: select Other (Docker V2 compliant).
  • URL: Enter the GCR URL for your GCP account.
    • Example: https://gcr.io/my-account.
  • Authentication:
    • Username: Enter _token.
      • The usage of _token as a username for GCP authentication typically occurs when using certain command-line utilities or API clients that require an access token instead of a traditional username and password.
    • Password: Enter the output of the gcloud auth print-access-token command using a Harness secret.

Ensure that the GCP IAM user you use has the correct permissions for pulling from GCR.

Deployment type support

Azure DevOps Artifacts are can be used with the following Harness deployment types:

  • SSH
  • WinRM
  • Azure Web Apps
  • Tanzu

Package type support

Harness supports Maven and Nuget package types.

Harness also supports universal packages, which enable developers to store an extensive array of package types that extend beyond the conventional ones. Note the following:

  • Currently support is limited to traditional VM deployments using SSH or WinRM.

  • Artifact source templates are not currently supported for universal packages.

Here's an example definition of a universal package in a Harness service definition:

service:
name: azure
identifier: azure
tags: {}
serviceDefinition:
spec:
artifacts:
primary:
primaryArtifactRef: <+input>
sources:
- identifier: azure
spec:
connectorRef: azure
scope: org
feed: universaltest68137
packageType: upack
package: my-first-package
version: 0.0.1
type: AzureArtifacts
type: AzureWebApp

Azure DevOps URL

This is the URL in your browser when you are in the Azure DevOps organization containing the projects and feed(s) you want to use.

For example, in this URL, https://dev.azure.com/garvit-test/sample-project/_packaging?_a=feed&feed=other-feed, you only need to use https://dev.azure.com/garvit-test in Harness connector Azure DevOps URL setting.

Permissions

You use an Azure DevOps Personal Access Token (PAT) to authenticate with Azure.

Create a Personal Access token as described in Authenticate access with personal access tokens from Azure.

Next, copy the token and paste it in the Harness Encrypted Text secret you use for the PAT in the Harness Azure Artifacts connector.

The PAT must have the Read permission in Packaging.

Azure DevOps artifacts expressions

You can reference artifact properties using the following expressions in a values YAML file or in any Harness setting that supports Harness expressions.

ExpressionDescriptionExample
<+artifact.connectorRef>Identifier of the connector used by the artifact sourceorg.azuredevops
<+artifact.identifier>Identifier of the artifact source in the service definitionAcmeAzureDevops

Harness Manager

You connect to ACR using a Harness Azure Connector. For details on all the Azure requirements for the Azure Connector, see Add a Microsoft Azure Cloud Connector.

To add an artifact from ACR, do the following:

  1. In your project, in CD (Deployments), select Services.

  2. Select Manage Services, and then select New Service.

  3. Enter a name for the service and select Save.

  4. Select Configuration.

  5. In Service Definition, select Kubernetes.

  6. In Artifacts, select Add Artifact Source.

  7. In Artifact Repository Type, click ACR, and then select Continue.

  8. In ACR Repository, select or create an Azure Connector that connects to the Azure account where the ACR registry is located.

  9. Select Continue.

  10. In Artifact Details, in Subscription Id, select the Subscription Id where the artifact source is located.

  11. In Registry, select the ACR registry to use.

  12. In Repository, select the repo to use.

  13. In Tag, enter or select the tag for the image.

    If you use runtime input, when you deploy the pipeline, Harness will pull the list of tags from the repo and prompt you to select one.

  14. Click Submit. The artifact is added to the Service Definition.

Permissions

The Harness Azure connectors that you'll use to connect Harness to ACR must have the Reader role, at minimum. You can also use a custom role that includes the permissions of the Reader role.

Reader role information

The Reader role must be assigned at the Subscription or Resource Group level that is used by the Application (Client) Id that you'll use in the Azure connector's settings. The application must have permission to list all container registries.

ACR Reader role

tip

Make sure you:

  • Don't put the Reader role in a different IAM section of Azure.
  • Don't provide only the AcrPull role, instead of Reader. It might appear that the AcrPull role gives access to a specific registry, but Harness needs to list all registries.

Custom role information

The following permissions (actions) are necessary for any Service Principal and/or Managed Identity user, regardless of whether you are using Kubernetes RBAC or Azure RBAC:

  • Microsoft.ContainerRegistry/registries/read
  • Microsoft.ContainerRegistry/registries/builds/read
  • Microsoft.ContainerRegistry/registries/metadata/read
  • Microsoft.ContainerRegistry/registries/pull/read
  • Microsoft.ContainerService/managedClusters/read
  • Microsoft.ContainerService/managedClusters/listClusterUserCredential/action
  • Microsoft.Resource/subscriptions/resourceGroup/read

For Helm deployments, the version of Helm must be >= 3.2.0. The Harness HELM_VERSION_3_8_0 feature flag must be activated.

You can't use Pod Assigned Managed Identity and System Assigned Managed Identity for the same cluster.

The following JSON sample creates a custom role with the required permissions. To use this sample, replace xxxx with the role name, subscription Id, and resource group Id.

Important notes

  • Harness supports 500 images from an ACR repo. If you don't see some of your images, then you might have exceeded this limit. This is the result of an Azure API limitation.
  • If you connect to an ACR repo via the platform-agnostic Docker Connector, the limit is 100.

Use Docker Registry connector for ACR

If you do not want to centrally manage service principles for access to ACR, you can use the platform-agnostic Docker Registry connector and repository-scoped permissions to connect Harness to ACR.

To use the Docker Registry connector to connect to ACR, do the following:

  1. In Azure ACR, in Repository permissions, select Tokens.
  1. Create a new token and scope map.
  1. Generate the password for the token.
  1. In Harness, create a new Docker Registry connector.
  2. For Provider Type, select Other.
  3. Select Username and Password for Authentication, and use the username and password for the ACR token.

ACR artifact expressions

You can reference artifact properties using the following expressions in a values YAML file or in any Harness setting that supports Harness expressions.

Create a service with an artifact source that uses the connector using the Create Services API.

Terraform Provider

For the Terraform Provider ECR connector resource, go to harness_platform_connector_aws.

ECR connector example

# Credential manual
resource "harness_platform_connector_aws" "test" {
identifier = "identifier"
name = "name"
description = "test"
tags = ["foo:bar"]

manual {
secret_key_ref = "account.secret_id"
delegate_selectors = ["harness-delegate"]
}
}

# Credentials inherit_from_delegate
resource "harness_platform_connector_aws" "test" {
identifier = "identifier"
name = "name"
description = "test"
tags = ["foo:bar"]

inherit_from_delegate {
delegate_selectors = ["harness-delegate"]
}
}

For the Terraform Provider service resource, go to harness_platform_service.

Harness Manager

You connect to ECR using a Harness AWS Connector. For details on all the ECR requirements for the AWS Connector, see AWS Connector Settings Reference.

To add an artifact from ECR, do the following:

  1. In your project, in CD (Deployments), select Services.

  2. Select New Service.

  3. Enter a name for the service and select Save.

  4. In Configuration > Service Definition, select Kubernetes.

  5. In Artifacts, select Add Artifact Source.

  6. In Artifact Repository Type, click ECR, and then select Continue.

  7. In ECR Repository, select or create an AWS connector that connects to the AWS account in which the ECR registry is located.

  8. Select Continue.

  9. In Artifact Details, in Region, select the region where the artifact source is located.

  10. (Optional) In Registry ID, enter the AWS account ID of the ECR registry you want to use. This field is useful when the AWS connector can access AWS accounts other than the one it is configured with. If you do not specify a registry ID, Harness uses the default registry associated with the AWS account.

  11. If the IAM user has access to the repository in the secondary account, in Registry ID, specify the AWS account ID associated with that repository.

    note

    Only Tags can be fetched from the repository in the secondary account. You must specify the image path manually.

  12. In Image Path, enter the name of the artifact you want to deploy.

  13. In Tag, enter or select the Docker image tag for the image.

    ECR artifact details

    If you use runtime input, when you deploy the pipeline, Harness will pull the list of tags from the repo and prompt you to select one.

  14. To specify an image digest, use Digest and the unique identifier for the image you want to use. Specifying an image by tag and digest (rather than tag alone) is useful when you want to deploy an image with a fixed digest/SHA for your service.

note

If an image with the specified tag/digest combination does not exist in the artifact registry, the pipeline will fail.

  1. Select Submit. The Artifact is added to the Service Definition.

ECR artifact source in a service

Permissions

Ensure that the AWS IAM user account you use in the AWS Connector has the following policy.

Pull from ECR policy

  • Policy Name: AmazonEC2ContainerRegistryReadOnly
  • Policy ARN: arn:aws:iam::aws:policy/AmazonEC2ContainerRegistryReadOnly
  • Description: Provides read-only access to Amazon EC2 Container Registry repositories.
  • Policy JSON:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [

"ecr:GetRepositoryPolicy",
"ecr:DescribeRepositories",
"ecr:ListImages",
"ecr:DescribeImages",
"ecr:BatchGetImage"
],
"Resource": "*"
}
]
}

Use Docker Registry for ECR

If you do not want to use the AWS connector for ECR, you can use the platform-agnostic Docker Registry connector.

Use the following settings:

  • Provider Type: select Other (Docker V2 compliant).
  • URL: Enter the same URL you would use in your push command.
    • For example, here is an ECR push command example:

      docker push 1234567890.dkr.ecr.us-east-2.amazonaws.com/my-private-repo:123.

    • Include the https:// scheme when you add the URL in URL.

    • Your URL will look something like this: https://1234567890.dkr.ecr.us-east-2.amazonaws.com.

  • Authentication:
    • Username: Enter AWS. Do not enter an access key or user name.

    • Password: Enter the password returned from the following command (replace us-east-2 with your region):

      aws ecr get-login-password --region us-east-2

Ensure that the AWS IAM user you use has the correct policies for pulling from ECR:

Pull from ECR policy

  • Policy Name: AmazonEC2ContainerRegistryReadOnly
  • Policy ARN: arn:aws:iam::aws:policy/AmazonEC2ContainerRegistryReadOnly
  • Description: Provides read-only access to Amazon EC2 Container Registry repositories.
  • Policy JSON:

}
]
}

AWS roles for IRSA auth

If you are using IRSA for authentication in the Harness AWS connector that pulls from ECR, ensure the following AWS roles are mapped to the Kubernetes service account.

  • ecr:DescribeImages
  • ecr:DescribeRepository
  • ecr:GetAuthorizationToken
  • ecr:BatchGetImage
  • ecr:GetDownloadUrlForLayer

    3. In Bucket Name, select the bucket where the artifact is located
    4. In File path, enter the path (from the bucket root) and name of the artifact you want to deploy.
  11. Select Submit.
    If you use runtime input, when you deploy the pipeline, Harness will pull the list of tags from the repo and prompt you to select one.
  12. Select Submit. The Artifact is added to the Service Definition.

Permissions

You need a dedicated S3 bucket for your artifacts and an AWS connector with read/write access to this bucket.

Sample S3 Cache Bucket Policy

{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "AllowS3BucketAccess",
"Effect": "Allow",
"Action": [
"s3:PutObject",
"s3:GetObject",
"s3:ListBucket",
"s3:DeleteObject"
],
"Resource": [
"arn:aws:s3:::your-s3-bucket/*",
"arn:aws:s3:::your-s3-bucket"
]
},
{
"Sid": "AllowDescribeRegions",
"Effect": "Allow",
"Action": "ec2:DescribeRegions",
"Resource": "*"
}
]
}

For more information on configuring an S3 connector and S3 bucket policies, go to Add an AWS connector and the AWS connector settings reference.

AWS S3 artifact expressions

You can reference artifact properties using the following expressions in a values YAML file or in any Harness setting that supports Harness expressions.

ExpressionDescriptionExample
<+artifact.connectorRef>Identifier of the connector used by the artifact sourceorg.aws
<+artifact.identifier>Identifier of the artifact source in the service definitionAcmeS3
<+artifact.type>This will be AmazonS3 alwaysAmazonS3
<+artifact.primaryArtifact>Boolean values. true in case of primary artifacttrue
<+artifact.filePath>Full path of the file in S3 bucketacme-apps/hello-world/v1.tgz
<+artifact.region>Region of S3 bucketus-east-1
<+artifact.bucketName>Name of the S3 bucketacme-lambda
<+artifact.metadata.get([KEY])>This is the metadata attached with the file in AWS S3. Popular keys include x-amz-server-side-encryption, Content-Type, Last-Modified.

AWS S3 File Filter

The artifact details settings include a File Filter (fileFilter) option.

In File Filter, you can enter a regex value and Harness will fetch all matching files. You can then select from the list in File Path.

This setting is optional. If you do not use it, Harness will fetch and display all files in the File Path setting.

If the File Path is a fixed value, during pipeline execution, artifact validation is performed using the File Path but not the File Filter. Harness does not check whether the File Filter matches or not during the execution.

Examples:

  • *: fetch all files in the file path.
  • *.zip: fetch all files in the file path with the extension .zip.
  • */w10/*.tfstate: fetch all files in the file path that contain /w10/ with the extension .tfstate.
  • */w1/*: fetch all files in the file path that contain /w1/.
  • w1: fetch all files in the file path that contain w1.

Amazon EC2 AMIs

Use Amazon EC2 AMI artifacts

You connect to Amazon AWS account using a Harness AWS connector. For details on all the AWS requirements for the connector, see AWS Connector Settings Reference.

For AWS AMI artifacts, a version number represents the name of AMI. You can filter names by using tags/filter values.

YAML

This example uses a Harness Delegate installed in AWS for credentials.

Harness Manager

You connect to Artifactory (JFrog) using a Harness Artifactory Connector. For details on all the requirements for the Artifactory Connector, go to Artifactory Connector Settings Reference.

To add an artifact from Artifactory, do the following:

  1. In your project, in CD (Deployments), select Services.
  2. Select Manage Services, and then select New Service.
  3. Enter a name for the service and select Save.
  4. Select Configuration.
  5. In Service Definition, select the deployment type.
  6. In Artifacts, select Add Artifact Source.
  7. In Artifact Repository Type, select Artifactory, and then select Continue.
  8. In Artifactory Connector, select or create an Artifactory connector that connects to the Artifactory account where the repo is located. Click Continue. The Artifact Details settings appear.
  9. Enter an Artifact Source Identifier and select the Repository Format.
  10. Set the artifact details based on the format:

Docker repository format

  1. In Repository, enter the repo name. If the full path is docker-remote/library/mongo/3.6.2, you would enter docker-remote.

  2. In Artifact/Image Path, enter the path to the artifact. If the full path is docker-remote/library/mongo/3.6.2, you would enter library/mongo.

  3. In Repository URL, enter the URL from the docker login command in Artifactory's Set Me Up settings.

  4. In Tag, enter or select the Docker image tag for the image.

    You can use a regex to select an image based on a matching pattern. Suppose you have a set of images with tags 3.1.1, 3.1.2, 3.1.3.1, 3.1.3.2, and 3.1.3.4. Select Regex, then set Tag Regex 3.1* to select the most recent image with prefix 3.1, in this case the image with tag 3.1.3.4.

  5. If you use runtime inputs when you deploy the pipeline, Harness will pull the list of tags from the repo and prompt you to select one.

  6. To specify an image digest, use Digest and the unique identifier for the image you want to use. Specifying an image by tag and digest (rather than tag alone) is useful when you want to deploy an image with a fixed digest/SHA for your service.

note

If an image with the specified tag/digest combination does not exist in the artifact registry, the pipeline will fail.

  1. Select Submit. The Artifact is added to the Service Definition.

Generic repository format

Figure 1: Elements in the Artifactory UI and their equivalents in the Artifact Details dialog box.
  1. In Repository, enter the repo name. If the full path is my-apps/myticketservice/1.0/ticket-service-1.0.jar, you would enter my-apps.

  2. Select the method for specifying the artifacts you want to deploy:

    • Artifact Directory Specify a hard-coded path to the artifacts.
    • Artifact Filter Use an expression to specify the path. Useful if you want to fetch artifacts from different paths.
  3. Specify the artifacts you want to deploy.

    • If you selected Artifact Directory:

      1. In Artifact Directory, enter the path to the artifacts. If the full path is my-apps/myticketservice/1.0/ticket-service-1.0.jar, you would enter myticketservice/1.0.
      2. Set Artifact Details to Value or Regex (to select an artifact based on a pattern).
      3. Specify the value or the regex for the artifact. If you selected Regex, enter the Artifact Path Filter for the latest artifact you want to fetch.
    • If you selected Artifact Filter, enter an expression that matches the artifacts you want to fetch. Here are some examples of expressions you can use:

      • */* : Fetch all artifacts from all directories including their subdirectories.
      • */*.zip : Fetch all .zip artifacts from all directories, including subdirectories.
      • *: Fetch all artifacts in the root directory.
      • *.zip : Fetch all .zip artifacts in the root directory.
      • folder/* : Fetch all artifacts contained in directory folder.
      • folder/*.zip : Fetch all .zip artifacts contained in directory folder.
      • folder/*/* : Fetch all artifacts from all directories/subdirectories under folder, for example folder/folder1, folder/folder1/folder2, folder/folder1/folder2/folder3, etc.
      • folder/*/*.zip : Fetch all .zip artifacts from all directories/subdirectories under folder.
      • folder*/* : Fetch all artifacts from directories/subdirectories that match folder*, for example folder, folder123, folder/x/y/z, etc.
      note

      You cannot apply a filter that finds BOTH artifacts in a folder AND all subdirectories under that folder. Thus folder/* finds artifacts in folder but no subdirectories, and folder/*/* finds artifacts in all subdirectories but not in folder.

    If you use a runtime input when you deploy the pipeline, Harness will pull the list of artifacts from the repo and prompt you to select one.

  4. Select Submit. The Artifact is added to the Service Definition.

Permissions

Make sure the following permissions are granted to the user:

  • Privileged User is required to access API, whether Anonymous or a specific username (username and passwords are not mandatory).
  • Read permission to all Repositories.

If used as a Docker Repo, user needs:

  • List images and tags
  • Pull images

See Managing Permissions: JFrog Artifactory User Guide.

Harness Manager

You connect to Github using a Harness Github Connector, username, and Personal Access Token (PAT).

To add an artifact from Github Packages, do the following:

  1. In your project, in CD (Deployments), select Services.

  2. Select Manage Services, and then select New Service.

  3. Enter a name for the service and select Save.

  4. Select Configuration.

  5. In Service Definition, select Kubernetes.

  6. In Artifacts, select Add Artifact Source.

  7. In Artifact Repository Type, select Github Package Registry, and then select Continue.

  8. In Github Package Registry Repository, select or create a Github Connector that connects to the Github account where the package repo is located.

    Ensure that you enable API Access in the Github connector, and use a Personal Access Token (PAT) that meets the requirements listed in Permissions.

  9. Select Continue.

  10. The Artifact Details settings appear.

  11. In Artifact Source Name, enter a name for this artifact source.

  12. In Package Type, select the type of package you are using.

  13. In Package Name, select the name of the package.

  14. In Version, select the version to use.

  1. To specify an image digest, use Digest and the unique identifier for the image you want to use. Specifying an image by digest is useful when you want to deploy an image with a fixed digest/SHA for your service.
note

If an image with the specified tag/digest combination does not exist in the Github Package registry repository, the pipeline will fail.

  1. Select Submit. The Artifact is added to the Service Definition.

Permissions

The Github Personal Access Token (PAT) must have the write:packages and read:packages permissions.

Ensure that you enable API access in the Harness Github connector. In the Github connector YAML, the setting is apiAccess:

Custom artifact source

Use artifacts from a custom artifact source

For enterprises that use a custom repository, Harness provides the Custom Artifact Source.

To use this artifact source, you provide a script to query your artifact server via its API (for example, REST) and then Harness stores the output on the Harness Delegate in the Harness-initialized variable $HARNESS_ARTIFACT_RESULT_PATH.

The output must be a JSON array, with a mandatory key for a Build Number/Version. You then map a key from your JSON output to the Build Number/Version variable.

For steps on adding a Custom Artifact source, go to Add a custom artifact source for CD.

Artifact limits and display in the Harness UI

The following table lists how many artifact versions Harness displays in its UI drop-downs, and how Harness sorts the versions.

Pull an image from a private registry

Typically, if the Docker image you are deploying is in a private registry, Harness has access to that registry using the credentials set up in the Harness connector you use with your service Artifacts.

Credentials to access Docker builds

If some cases, your Kubernetes cluster might not have the permissions needed to access a private Docker registry.

For these cases, the values YAML file in Service Definition Manifests section must use the dockercfg parameter.

If the Docker image is added in the Service Definition Artifacts section, then you reference it like this: dockercfg: <+artifacts.primary.imagePullSecret>.

This key will import the credentials from the Docker credentials file in the artifact.

Open the values.yaml file you are using for deployment.

Verify that dockercfg key exists, and uses the <+artifacts.primary.imagePullSecret> expression to obtain the credentials:

name: <+stage.variables.name>  
replicas: 2

image: <+artifacts.primary.image>
dockercfg: <+artifacts.primary.imagePullSecret>

createNamespace: true
namespace: <+infra.namespace>
...

Reference dockercfg in Kubernetes objects

Next, verify that the Deployment and Secret objects reference dockercfg: {{.Values.dockercfg}}.

...  
{{- if .Values.dockercfg}}
apiVersion: v1
kind: Secret
metadata:
name: {{.Values.name}}-dockercfg
annotations:
harness.io/skip-versioning: true
data:
.dockercfg: {{.Values.dockercfg}}
type: kubernetes.io/dockercfg
---
{{- end}}

apiVersion: apps/v1
kind: Deployment
metadata:
name: {{.Values.name}}-deployment
spec:
replicas: {{int .Values.replicas}}
selector:
matchLabels:
app: {{.Values.name}}
template:
metadata:
labels:
app: {{.Values.name}}
spec:
{{- if .Values.dockercfg}}
imagePullSecrets:
- name: {{.Values.name}}-dockercfg
{{- end}}
containers:
- name: {{.Values.name}}
image: {{.Values.image}}
...

With these requirements met, the cluster imports the credentials from the Docker credentials file in the artifact.

warning

When selecting artifacts/tags in Harness dropdown menus, if the artifacts/tags use Harness expressions, please keep in mind that some expressions can’t be resolved outside of pipeline execution. For example, artifacts/tags expressions using <+project.name> or <+org.name> will not resolve to values in runtime dropdowns, including those used to load tags.

Sidecar workloads

You can use Harness to deploy both primary and sidecar Kubernetes workloads.

Kubernetes sidecar workloads are a powerful way to modularize and encapsulate application functionality while keeping the overall architecture simple and easy to manage.

Sidecars are commonly used to implement cross-cutting concerns like logging, monitoring, and security. By separating these concerns into separate containers, it's possible to add or modify them without affecting the primary container or the application running inside it.

For example, a logging sidecar can be used to capture and store application logs, metrics, and other data, without requiring the primary container to implement any logging code.

Sidecars can also be used to implement advanced features like load balancing, service discovery, and circuit breaking. By using a sidecar container for these features, it's possible to keep the primary container simple and focused on its core functionality, while still providing advanced capabilities to the application.

For more information, go to Add a Kubernetes sidecar container.

Propagate and override artifacts, manifests, and service variables

You can propagate services between stages and override service settings by using multiple values YAML files and/or Environment Overrides.

For more information, go to:

Viewing SHA values and labels

Harness provides expressions you can use to output the SHA values and labels of the Docker images for the following artifact providers:

  • Docker Registry (platform agnostic)
  • Artifactory
  • ECR
  • GCR
  • Google Artifact Registry
  • Nexus 3 Docker
  • ACR
  • Github Packages

SHA values and labels for the artifact are now visible in the Harness service Output section of a pipeline execution.

Labels are visible if the artifact manifest supports schemaVersion1.

Labels can be referenced using the expression: <+pipeline.stages.[stage Id].spec.artifacts.primary.label.get("labelKey")>.

Since manifests can support two schema versions, schemaVersion1 and schemaVersion2, there could be SHA values for each schema version.

Here are the expressions for referencing each version:

  • SHA value of schemaVersion1: <+artifacts.primary.metadata.SHA> (same stage) or <+pipeline.stages.[stage Id].spec.artifacts.primary.metadata.SHA>.
  • SHA value of schemaVersion2: <+artifacts.primary.metadata.SHAV2> (same stage) or <+pipeline.stages.[stage Id].spec.artifacts.primary.metadata.SHAV2>.

If the service is configured to use an image with a specific digest, you can access the digest using <+pipeline.stages.STAGE_ID.spec.artifacts.primary.digest>.
