CircleCI Kubernetes Release Agent Helm Chart

A Helm chart for installing CircleCI’s Kubernetes release agent.

Version: 1.2.1 Type: application AppVersion: 1.2.1 CircleCI

Prerequisites

We generally support the two latest minor versions of Kubernetes, Helm, and Argo Rollouts (optional).

Optional

Installing the Agent

Agent Image

Our Kubernetes Release Agent Images are available from CircleCI’s public Docker Hub registry, located here: https://hub.docker.com/r/circleci/k8s-release-agent/tags

The default image for this chart version is: circleci/k8s-release-agent:1.2.1

Agent Integration Token

The required token can be obtained by navigating to the Releases view of the CircleCI web application, clicking on Configure Integrations in the top-right, and then Configure New Integration.

Ensure that the generated token is accessible for the installation process.

Installing via Helm Chart

  1. Add the Helm chart repository: 
     helm repo add release-agent https://circleci-public.github.io/cci-k8s-release-agent
  2. Update your local Helm chart repository cache: 
     helm repo update
  3. Install the Helm chart: 
     helm upgrade --install cci-release-agent release-agent/circleci-release-agent \
 --set tokenSecret.token=[YOUR_CCI_INTEGRATION_TOKEN] --create-namespace \
 --set "managedNamespaces={namespace1,namespace2}" \
 --namespace circleci-release-agent-system

Important Update for Upgrading Users

We have made a small but significant change in the helm installation command that you need to be aware of. The argument name manageNamespaces has been corrected to managedNamespaces. The corrected command is shown above. Please make sure to use managedNamespaces instead of manageNamespaces when installing or upgrading to the newer versions of the software. If you have any scripts or automation that includes the previous command, they need to be updated to use managedNamespaces.

Updating the Agent

  1. Update your local Helm cache: 
     helm repo update
  2. Upgrade to the new version: 
     helm upgrade --install cci-release-agent release-agent/circleci-release-agent \
 --set tokenSecret.token=[YOUR_CCI_INTEGRATION_TOKEN] --create-namespace \
 --set "managedNamespaces={namespace1,namespace2}" \
 --namespace circleci-release-agent-system
