[JENKINS-73043] Pipeline fails on rootless docker (context not found)

Trying to use docker.withRegistry results in:

Failed to initialize: unable to resolve docker endpoint: context "rootless": context not found: open /var/lib/jenkins/workspace/r_PROJECT_NAME_master@​tmp/a5534a4f-0526-4110-af60-6d9dcc324f14/contexts/meta/12b961af5feb3e9d39f93b2cefb9a1a944f18d02cca0cac2f04f5a982240605f/meta.json: no such file or directory

I'm trying to run rootless docker, but AFAIK the issue is with running a non-default context. It should be looking in /var/lib/jenkins/.docker/contexts/meta rather than in workspace.

 

$ docker context inspect rootless
