Following are the steps to create In-cluster registry and to execute build, push and pull operations in registry-pod

1. Setup Registry Pod

• Login to IBM Cloud and cluster via CLI
• Clone this REPO in local machine
• Run kubectl apply -f registry-pod.yaml to create registry pod and service
• Run kubectl get ep | grep ^re and copy the ENDPOINTURL
• Run following command to debug your node

kubectl debug node/<NODEIP> -it --image=ubuntu:latest

• Export REGISTRYPATH by

export REGISTRYPATH="<ENDPOINTURL>"

• Make directory with name of registry url

mkdir host/etc/containerd/certs.d/${REGISTRYPATH} && cd host/etc/containerd/certs.d/${REGISTRYPATH}

• Create hosts.toml and add regsitry URL by executing the following command

cat >hosts.toml<<EOL
server = "http://${REGISTRYPATH}"
[host."http://${REGISTRYPATH}"]
  skip_verify = true
EOL

• Exit from node debugger by cmd exit

2. Setup Builder Pod

• In builder-pod.yaml file update your ENDPOINT URL in this line
• Run kubectl apply -f builder-pod.yaml
• This will build the dockerfile and push to the registry

3. Setup Pull pod/ peer pod

• In peer-pod.yaml file update your ENDPOINT URL in this line
• Run kubectl apply -f peer-pod.yaml
• This will create a pod with image from in-cluster registry
