Devfile Registry Operator

The Devfile Registry operator manages the lifecycle of the following custom resources:

1. Devfile Registry
2. Devfile Registries List
3. Cluster Devfile Registries List

Releases

Minor releases will be scheduled roughly on a quarterly basis and will include non-feature breaking changes made between release cycles.

Patch releases are provided as needed for critical bug fixes and security patches, it is strongly recommended for users running on the same minor version of the registry operator to update when these releases become available.

Releases are available on GitHub along with bundle entries on OperatorHub.io and the OpenShift OperatorHub community catalog.

For more updates on releases, please join our communication channels.

Issue Tracking

Issue tracking repo: https://github.com/devfile/api with label area/registry

Changelog

This repository utilizes Release Notes to track and display changes, a changelog for every release can be found here.

Requirements

Deployment cluster must meet one of the following criteria:

• OpenShift Container Platform (OCP) 4.12.x
• Kubernetes 1.25.x-1.26.x

More on the support of container orchestration systems can be found here.

Deployments made by the devfile registry operator must never target the default namespace due to incompatibility with security setups.

Development

• Go 1.19.x
• Docker / Podman
• Operator SDK 1.28.x

See Upgrade SDK Version for a guide on updating the Operator SDK. Ensure the Operator SDK version and the version of Kubernetes APIs match each other when updating by checking CLUSTER_SUPPORT.md.

Running the controller in a cluster

Install cert-manager to provision self-signed certificates for the validating webhooks which are used specifically for the ClusterDevfileRegistriesList and DevfileRegistriesList CRs. Cert manager needs to be installed in order for the controller manager to start.

make install-cert

The controller can be deployed to a cluster provided you are logged in with cluster-admin credentials:

make install && make deploy

The operator will be installed under the registry-operator-system namespace. However, devfile registries can be deployed in any namespace.

Deploying registry to a cluster

After the operator has been installed to a cluster you can deploy a devfile registry by following these instructions.

Development

The repository contains a Makefile; building and deploying can be configured via the environment variables

Testing

Detailed instructions on how to run tests for the Devfile Registry Operator are found in CONTRIBUTING.md.

Run operator locally

It's possible to run an instance of the operator locally while communicating with a cluster.

1. You may need to install the controller-gen tool before, used when building the binary:

make controller-gen

2. Build the binary

make manager

3. Deploy the CRDs

make install

4. Run the controller

make run ENABLE_WEBHOOKS=false

Contributing

Please see our CONTRIBUTING.md.

Known Issues

• make test-integration times out when running in Minikube
• Headless mode field does not update devfile registry state during reconcile
• make bundle removes alm-examples for DevfileRegistriesList and ClusterDevfileRegistriesList CRDs due to bug with Kustomize
