OpenShift GitOps Operator

An operator that gets you an Argo CD for cluster configuration out-of-the-box on OpenShift along with the UI for visualizing environments.

Getting started

Making the operator available on the in-cluster OperatorHub

Add the following resource to your cluster:

apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
  name: gitops-service-source
  namespace: openshift-marketplace
spec:
  displayName: 'Gitops Service by Red Hat'
  image: 'quay.io/<quay-username>/gitops-operator-index:v0.0.1'
  publisher: 'Red Hat Developer'
  sourceType: grpc

Go to the OperatorHub on OpenShift Webconsole and look for the "OpenShift GitOps" operator.

Install the operator in the openshift-gitops-operator namespace using the defaults in the wizard, and optionally, select the checkbox to enable cluster monitoring on the namespace. Wait for it to show up in the list of "Installed Operators". If it doesn't install properly, you can check on its status in the "Installed Operators" tab in the openshift-gitops-operator namespace.

To validate if the installation was successful, look for the route named cluster in the openshift-gitops namespace. Note: the namespace doesn't have to exist in advance, the operator creates it for you.

That's it! Your API route should be created for you. You don't need to explicitly create any operand/CR.

Contributing

Clone the repository.
Login to a cluster on your command-line.
Execute make install to apply the CRDs.
Execute make run to run the operator locally.

Tests

Unit tests

make test

e2e tests

make test-e2e

Re-build and Deploy

This operator currently deploys the following payload:

quay.io/<quay-username>/gitops-backend:v0.0.1

If that's all that you are changing, the following steps are not needed in development mode. You could update your image "payload" and re-install the operator.

Set the base image and version for building operator, bundle and index images.

export IMAGE=quay.io/<quay-username>/gitops-operator VERSION=1.8.0

Build and push the operator image.

make docker-build docker-push

Build and push the Bundle image ( operator + OLM manifests )

make bundle
make bundle-build bundle-push

Build and push the Index image

Install opm binary which is required to build index images

make opm

make catalog-build catalog-push

The Index image powers the listing of the Operator on OperatorHub.

Migrate from Argo CD Community Operator to GitOps Operator

Please follow the migration guide when moving from the Argo CD Community Operator to the GitOps Operator.

Progressive Delivery

OpenShift GitOps from release v1.9.0 supports progressive delivery using Argo Rollouts.

Users can enable progressive delivery by using a new type of CRD called RolloutManager. A detailed usage guide for this new CRD is available here.
