The default url is correct, why are you setting it to that address?

from https://docs.ansible.com/ansible/latest/collections/community/docker/docker_login_module.html

registry_url string The registry URL. Default: "https://index.docker.io/v1/"

via CLI

$ docker info | grep Registry
Registry: https://index.docker.io/v1/

the error says that the module cannot talk to your Docker daemon.

You didn't configure any way to talk to the Daemon, so the default is
used, which means using a Unix socket /var/run/docker.sock.

When trying to access /var/run/docker.sock, a FileNotFoundError error
was raised.

You can probably resolve this by telling the module how to connect to
your Docker daemon. (The most easy way to do that is to use the
community.docker.docker module defaults group, then you only have to do
it once for all modules in your play. Alternatively you can use
environment variables, which should work fine for localhost - it's more
tricky on remote hosts.)

Cheers,
Felix

Ok that worked but I now keep getting a new error when I go to task 2:

 - name: run command
      community.docker.docker_container_exec:
        container: ubuntu
        command: /bin/bash -c "ls -lah"
        chdir: /root
      register: result

    - name: Print stdout
      debug:
        msg: '{{result}}'

I get this:

fatal: [localhost]: FAILED! => {"changed": false, "msg": "Could not find container \"ubuntu\""}

am i suppose to pull it not sure here

Thanks 

Bill

Hi,

does `docker container list` show a container with name `ubuntu`? If
not, the error message is completely accurate. The
docker_container_exec module does something similar to `docker exec -w
/root ubuntu /bin/bash -c "ls -lah"`.

If you don't have a container called `ubuntu`, you first have to start
one so you can run a command in it. Or alternative, use the
docker_container module to create a new container and run that command
directly in it (with `detach: false`).

Cheers,
Felix
