On page 3 of lab 3, it says.

"To test that, you have a working setup, use etcdctl in the etcd container, and list the what is the

/registry directory:

$ docker exec -ti k8s etcdctl /bin/sh"

When I do that, I get this message:

"No help topic for '/bin/sh'"

Thanks for any help.

    The command should be: docker exec -ti k8s /bin/sh. See I have omitted "etcdctl" part, with this command you will have interactive (-it flags) shell access to the etcd container.


    $ docker exec -ti k8s etcdctl /bin/sh

    No help topic for '/bin/sh'

  • Yeah, you are right, I am also struggling for 2 days. Wasted my time removing and running the container images so many times. And when googled online some people say: ​there is no directory in etcd v3. Ahh, so irritating.

  • ETCDCTL_API=3 etcdctl --endpoints=http://localhost:2379 get / --prefix --keys-only
