podman volume rm etcdvolume -f

Build test container

podman build -t etcd-wrapper .

Run test cluster

podman play kube test/outputs/node0-wrapper.yaml
podman play kube test/outputs/node1-wrapper.yaml
podman play kube test/outputs/node2-wrapper.yaml

Check backups

podman exec minio-mc mc ls m/etcd/integ

Run etcd only

podman play kube test/outputs/node0.yaml
podman play kube test/outputs/node1.yaml
podman play kube test/outputs/node2.yaml

Test query

podman exec -it node0-etcd etcdctl --endpoints=https://127.0.0.1:8080 \
