Concourse resource for artifacts in an OCI registry

Fetches, verifies and publishes Helm Charts from a running OCI registry.

Installation

Add a new resource type to your Concourse CI pipeline:

- name: oci-registry
  type: docker-image
  source:
    repository: ghcr.io/cloudoperators/concourse-oci-helm-chart-resource
    tag: f932b76 # Replace with the latest stable release.

Configuration

  - name: my.chart
    type: oci-registry
    source:
      registry: ghcr.io/cloudoperators
      repository: all-my-helm-charts
      chart_name: my-chart

Authentication

The resource supports two ways of authenticating against the registry:

• By default, the docker credential store is used.
• Use the auth_username and auth_password parameters within the source block for basic authentication.

Behavior

The resource implements the check and in action.

check: Check for new versions of the Helm chart

Checks for new versions of the specified Helm chart. Returns the latest version of the Helm chart based on semantic versioning.
