docker-image: instance server ssh not working

[sdurrheimer]

Description:

The instance server ssh command is not working with the docker image.
As the base image is scratch it doesn't contain the ssh command being executed by the CLI.

How to reproduce:

• Have an existing server running
• Use the scw instance ssh command via the docker image

Command attempted

$ docker run -i --rm -v $HOME/.config/scw:/.config/scw scaleway/cli:v2.2.0 instance server ssh <server-id>

Expected Behavior

Working SSH connection, or complaining that I didn't provide an authorized ssh key.

Actual Behavior

$ docker run -i --rm -v $HOME/.config/scw:/.config/scw scaleway/cli:v2.2.0 instance server ssh <server-id>
Exec: "ssh": executable file not found in $PATH

More info

It would be probably better to use a base image able to have an ssh-client installed (alpine, debian-slim, etc.).
Most people will expect the CLI to behave the same with or without using the docker image.
