Waiting for SSH service on Test Kitchen with the Docker driver

Featured image for sharing metadata for article

Although the Docker driver is no longer included by default in the Chef Workstation, with kitchen-dokken being recommended now, you may still want to use it.

I was trying to run one of my older cookbooks, which uses it for integration tests, and found that my container was just timing out trying to connect:

Waiting for SSH service on localhost:49156, retrying in 3 seconds
Waiting for SSH service on localhost:49156, retrying in 3 seconds
Waiting for SSH service on localhost:49156, retrying in 3 seconds

This is odd, because I could see the container running, but nothing was happening with it, so there shouldn't have been a timeout.

When running Kitchen with debug logs, I could see Connection reset by peer, which was increasingly odd:

D, [2021-04-07T13:46:32.165084 #122004] DEBUG -- default-debian: [SSH] connection failed (#<Errno::ECONNRESET: Connection reset by peer>)
I, [2021-04-07T13:46:32.165222 #122004]  INFO -- default-debian: Waiting for SSH service on localhost:49156, retrying in 3 seconds

It turns out that I was missing the transport configuration in my kitchen.yml:

transport:
  name: docker

Once I'd added this, the connection worked straight away, and my tests ran successfully.
