NOTES:
** Please be patient while the chart is being deployed **

etcd can be accessed via port 2379 on the following DNS name from within your cluster:

    etcd.service.svc.cluster.local

To create a pod that you can use as a etcd client run the following command:

    kubectl run etcd-client --restart='Never' --image docker.io/bitnami/etcd:3.5.0-debian-10-r64 --env ETCDCTL_ENDPOINTS="etcd.service.svc.cluster.local:2379" --namespace service --command -- sleep infinity

Then, you can set/get a key using the commands below:

    kubectl exec --namespace service -it etcd-client -- bash
    etcdctl  put /message Hello
    etcdctl  get /message

To connect to your etcd server from outside the cluster execute the following commands:

    kubectl port-forward --namespace service svc/etcd 2379:2379 &
    echo "etcd URL: http://127.0.0.1:2379"
