Let’s do GitOps using ArgoCD on OpenShift

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes (OpenShift). Argo CD follows the GitOps pattern of using Git repositories as the source of truth for defining the desired application state.

Installing ArgoCD Operator on OpenShift

To deploy ArgoCD, you can follow the ArgoCD Operator installation guide here. To ease out things for you (and me), i composed a nifty yaml that can deploy ArgoCD on an OpenShift 4 ( tested on v4.7 ) cluster. Github Repo

git clone https://github.com/ksingh7/argocd-openshift.git
cd argocd-openshift
# Login as Kubeadmin
# Deploy ArgoCD Operator
oc create -f 1_argocd_operator.yaml

This will create a namespace argocd and create an openshift subscription for argocd-operator . Once created you can validate the deployment of ArgoCD Operator is successful, by checking on the pods oc get po
