I am seeing Host key verification failed errors in the Multibranch Pipeline Scan Logs of a brand new Jenkins instance, configured entirely through the Configuration-as-Code plugin.
My Job DSL multibranchPipelineJob definition uses a git@myserver.com:namespace/repo URL in its git branchSources.
I have figured out that as soon as I change the URL from git@ to https://, the error goes away, but - really - this just feels like a workaround.
As far as I understand, multibranchPipelineJob scans run on the Jenkins instance itself - not one of its build agents.
As such, I imagine this is simply a case of adding the host key in some known_hosts file, but I am not looking for the manual "log in to the server, as the jenkins user and add the key yourself" solution, that has been proposed elsewhere.
Rather, I am wondering if anyone knows of a way to add this key either through the Configuration-as-Code casc.yaml file, or if this would be something I should add as a Volume in the Pod that runs Jenkins itself.
