Install Delegate

What is a Delegate?

Harness Delegate is a lightweight worker process that is installed on your infrastructure and communicates only via outbound HTTP/HTTPS to the Harness Platform. This enables the Harness Platform to leverage the delegate for executing the CI/CD and other tasks on your behalf, without any of your secrets leaving your network.

You can install the Harness Delegate on either Docker or Kubernetes.

Install Delegate

Create New Delegate Token

Login to the Harness Platform and go to Account Settings -> Account Resources -> Delegates. Click on the Tokens tab. Click +New Token and give your token a name `firstdeltoken`. When you click Apply, a new token is generated for you. Click on the copy button to copy and store the token in a temporary file for now. You will provide this token as an input parameter in the next delegation installation step. The delegate will use this token to authenticate with the Harness Platform.

Get Your Harness Account ID

Along with the delegate token, you will also need to provde your Harness accountId as an input parameter to the delegate installation. This accountId is present in every Harness URL. For example, in the following URL

https://app.harness.io/ng/#/account/6_vVHzo9Qeu9fXvj-AcQCb/settings/overview

6_vVHzo9Qeu9fXvj-AcQCb is the accountId.

Now you are ready to install the delegate on either Docker or Kubernetes.

Prerequisite

Ensure that you have the Docker runtime installed on your host. If not, use one of the following options to install Docker:

Install on Docker

Now you can install the delegate using the following command.

docker run -d --name="firstdockerdel" --cpus="0.5" --memory="2g" \
-e DELEGATE_NAME=firstdockerdel \
-e NEXT_GEN=true \
-e DELEGATE_TYPE=DOCKER \
-e ACCOUNT_ID=PUT_YOUR_HARNESS_ACCOUNTID_HERE \
-e DELEGATE_TOKEN=PUT_YOUR_DELEGATE_TOKEN_HERE \
-e MANAGER_HOST_AND_PORT=PUT_YOUR_MANAGER_HOST_AND_PORT_HERE \
harness/delegate:22.11.77436

PUT_YOUR_MANAGER_HOST_AND_PORT_HERE should be replaced by the Harness Manager Endpoint noted below. For Harness SaaS accounts, you can find your Harness Cluster Location in the Account Overview page under Account Settings section of the left navigation. For Harness CDCE, the endpoint varies based on the Docker vs. Helm installation options.

Harness Cluster LocationHarness Manager Endpoint on Harness Cluster
SaaS prod-1https://app.harness.io
SaaS prod-2https://app.harness.io/gratis
SaaS prod-3https://app3.harness.io
CDCE Dockerhttp://<HARNESS_HOST> if Docker Delegate is remote to CDCE or http://host.docker.internal if Docker Delegate is on same host as CDCE
CDCE Helmhttp://<HARNESS_HOST>:7143 where HARNESS_HOST is the public IP of the Kubernetes node where CDCE Helm is running

Verify Docker Delegate Connectivity

Click Continue and in a few moments after the health checks pass, your Docker Delegate will be available for you to leverage. Click Done and can verify your new Delegate is on the list.

Delegate Available

You can now route communication to external systems in Harness connectors and pipelines by simply selecting this delegate via a delegate selector.
