Using Docker backend on a remote Docker host/container

I’d like to be able to use the testinfra convenience methods provided by the Docker backend on a REMOTE Docker container.

Is this possible?

I know that I could use ssh or paramiko connection to connect to the remote Docker host but I would have to “manually” docker exec into my container. I would not be able to use the testinfra convenience methods (.file, .package etc.) on the container itself.

Hi @ecks , I’ll be happy to review a PR from you, thanks!

I think the + character can be used but I’d rather use it to separate the “whole” connection string, like:

ssh://user@host_2+docker://user@docker_id

Then we can just split on + and parse both connection strings. Then write some funny code to handle the “backend” chaining 😃

hmm yeah that sounds like it would be pretty useful. I could potentially work on a PR for that. I took a look at the source and looks like urlparse is used to parse the URI. So I don’t think the symbol ‘+’ is parsed, and if you do something like

urlparse("ssh+docker://user@host_2+user@docker_id")

in netloc the value would be user2@host1+user1@host2, which we can split on. What are your thoughts, does that URI look pretty readable?
