Install Harness Self-Managed Enterprise Edition using Helm

This document explains how to use Helm to install, upgrade or uninstall Harness Self-Managed Enterprise Edition. This document describes an installation on Google Kubernetes Engine (GKE). The same installation process, however, applies to installations on Kubernetes versions 1.x and later.

Helm package manager provides a declarative approach to Kubernetes application management in which software packages are specified as “charts.” For more information, see the Helm documentation.

Download Harness Helm chart​

To download Harness Helm chart for the installation of Self-Managed Enterprise Edition, see https://github.com/harness/helm-charts.

Harness Helm chart is available for demonstration and production environments.

Update the override.yaml file​

Depending on your target environment, you'll need to update the override.yaml file to specify a load balancer or to specify the Harness modules to be deployed.

Add a load balancer​

Use the following procedure to add a load balancer.

To add the URL for a load balancer

  1. In the values.yaml file, set the global.loadbalancerURL field to the URL of your load balancer. This is the URL you use for Harness.

    global:  
     # -- Harness Application URL  
     loadbalancerURL: http://<load-balancer-IP-address>  
     host_name: "<load-balancer-IP-address>"

  2. Set the host_name field to the IP address of the load balancer.

  3. Save the file.

Deploy Harness modules​

Harness Helm chart includes Harness Platform components. You can add modules by editing the override.yaml file.

The Platform component and below module is enabled by default:

  • Harness Continuous Deployment (CD) - Next Generation

The below Harness modules can be enabled or disabled conditionally:

  • Harness Continuous Integration (CI)
  • Harness Security Testing Orchestration (STO)
  • Harness Service Reliability Management (SRM)
  • Harness Feature Flags (FF)

You can conditionally disable or enable the CI and STO modules by specifying a boolean value in the enabled field of the YAML:

CI module​

ci:
# -- Enable to deploy CI to your cluster
enabled: true

SRM module​

srm:
# -- Enable to deploy SRM to your cluster
enabled: true

FF module​

ff:
# -- Enable to deploy FF to your cluster
enabled: true

STO module​

sto:
# -- Enable to deploy STO to your cluster
enabled: true

Install the Helm chart​

To use the charts, you must install Helm. To get started with Helm, see the Helm documentation. After you install Helm, follow the instructions below.

To install the Helm chart

  1. Add the repository.

    $ helm repo add harness https://harness.github.io/helm-charts

  2. Create a namespace for your installation. 

    $ kubectl create namespace <namespace>

  3. Modify the override.yaml file with your environment settings.

  4. Install the Helm chart. 

    $ helm install my-release harness/harness-prod -n <namespace> -f override.yaml

Verify installation​

After the installation completes, the services that were installed are enumerated with their status.

The services that appear depend on the modules that were installed.

To verify installation

  1. Review the list of services.

  2. In your browser, type the following instruction: 

    http://localhost/auth/#/signup

    If the installation was successful, the Harness Sign up page appears.

Upgrade the Helm chart​

Use the following instructions to upgrade the chart to a new release. 

To upgrade the chart

  1. Use the following command to obtain the release name for the earlier release. 

    $ helm ls -n <namespace>

  2. Retrieve the values for the earlier release. 

    $ helm get values my-release > old_values.yaml

  3. Change the values of the old_values.yaml file as required.

  4. Use the helm upgrade command to update the chart. 

    $ helm upgrade my-release harness/harness-demo -n <namespace> -f old_values.yaml

Uninstall the Helm chart​

To remove the Kubernetes components associated with the chart and delete the release, uninstall the chart.

To uninstall the chart

  • Uninstall and delete the my-release deployment:

    $ helm uninstall my-release -n <namespace>

Images for disconnected networks​

If your cluster is in an air-gapped environment, your deployment requires the following images:
