Deploying the SNO Quickstart

Fork reposity to your own repo

curl -OL https://raw.githubusercontent.com/tosin2013/openshift-demos/master/quick-scripts/deploy-gitea.sh
chmod +x deploy-gitea.sh
./deploy-gitea.sh

Login into the OpenShift Cluster as a cluster-admin user

oc login -u kubeadmin -p <password> https://api.<cluster-name>.<domain>:6443

run deploy.sh script

git clone https://github.com/tosin2013/sno-quickstarts.git
cd sno-quickstarts/gitops
./deploy.sh

add registry to ArgoCD cluster

Configure Cluster

Review Argo CD Applications before deployment
