Trento runner reports all checks in green if the ssh command is not available

[arbulu89]

During the usage of the initial version of the K3S and trento container (distroless), we had the scenario where the runner was reporting all checks as green (even when they fail), as it was not finding the ssh command within the container:

Unable to execute ssh command line on a controller due to: [Errno 2] No such file or directory: b'ssh'

This is pretty strange scenario, but it might happen.
There are different potential fixes:

• Do some ansible code to set as unresolved if this scenario happens, and besides this report the exact cause of the issue
• Check in the golang runner code if ssh tool is available
• Etc

How to reproduce
Reproducing the issue is not that simple using plain Trento binaries. I have done the next:

• Update the runner/consultemplate.go file the line 45, and add the ansible_connection=ssh value. It would look like this: {{ $nodename }} %[1]s={{ keyOrDefault (printf "%[4]s" $clusterId) "" }} ansible_connection=ssh ansible_host={{ $host }} ansible_user={{ $user }}
• Build the the image
• Enable some check that you know that it should fail
• In the machine where the runner is being executed, rename the ssh tool -> mv /usr/bin/ssh /usr/bin/ssh.backup

Following these steps the same output should be there

Issue still happening. It doesn't have an easy solution as it is somehow an ansible internal error. When ssh is not available the task is set as ignored but it doesn't really return any value.
In any case, as we now already install ssh correctly in the docker container, the issue is not likely to happen.
I would consider the issue a low priority.
