Configure delegate proxy settings

All delegates include proxy settings you can use to change how the delegate connects to the Harness Manager.

By default, the Harness Delegate uses HTTP and HTTPS in its Proxy Scheme settings.

Kubernetes delegate proxy settings​

The proxy settings are in the harness-delegate.yaml file:

...
        - name: PROXY_HOST
          value: ""
        - name: PROXY_PORT
          value: ""
        - name: PROXY_SCHEME
          value: ""
        - name: NO_PROXY
          value: ""
        - name: PROXY_MANAGER
          value: "true"
        - name: PROXY_USER
          valueFrom:
            secretKeyRef:
              name: doc-example-proxy
              key: PROXY_USER
        - name: PROXY_PASSWORD
          valueFrom:
            secretKeyRef:
              name: doc-example-proxy
              key: PROXY_PASSWORD
...

The PROXY_MANAGER setting determines whether the delegate bypasses proxy settings to reach the Harness Manager in the cloud. If you want to bypass, enter false.

In-Cluster Kubernetes delegate with proxy​

If an in-cluster Kubernetes delegate has a proxy configured, then NO_PROXY must contain the cluster master IP. This enables the delegate to skip the proxy for in-cluster connections.

Sample Docker delegate installation script with a proxy scheme​

The following script installs a Docker delegate with an HTTP proxy scheme.

docker run --cpus=1 --memory=2g \
  -e DELEGATE_NAME=docker-delegate \
  -e RUNNER_URL=https://<YOUR_RUNNER_URL> \
  -e DELEGATE_TAGS=macos-amd64 \
  -e PROXY_HOST=YOUR_PROXY_HOST_IP \
  -e PROXY_PORT=YOUR_PROXY_PORT \
  -e PROXY_SCHEME=http \
  -e NEXT_GEN="true" \
  -e DELEGATE_TYPE="DOCKER" \
  -e ACCOUNT_ID=YOUR_ACCOUNT_ID \
  -e DELEGATE_TOKEN=YOUR_DELEGATE_TOKEN \
  -e LOG_STREAMING_SERVICE_URL=https://<YOUR_LOG_STREAMING_SERVICE_URL> \
  -e MANAGER_HOST_AND_PORT=https://<YOUR_MANAGER_HOST_AND_PORT>/delegate:23.09.80505

Subnet masks not supported​

You cannot use delegate proxy settings to specify the Cluster Service Network CIDR notation and make the delegate bypass the proxy to talk to the Kubernetes API.

Harness does not allow any methods of representing a subnet mask.

The mask should be set in the cluster itself. For example:

kubectl -n default get service kubernetes -o json | jq -r '.spec.clusterIP'

Harness supports mTLS authentication on a case-by-case basis. Contact Harness Support to enable it.
