Description of problem:

It seems Jenkins doesn't support ssh git at this moment.

Jenkinsfile is on a git server and that git server only support ssh key auth. BuildConfig looks like:

source:
  git:
    ref: jenkins
    uri: git:nekop/hello-sinatra.git
  type: Git
strategy:
  jenkinsPipelineStrategy:
    jenkinsfilePath: Jenkinsfile
  type: JenkinsPipeline

Adding ssh key secret under sourceSecret doesn't work and it seems Jenkins never use that secret.

We can manually add an ssh credential on Jenkins, add the credential to the pipeline job. But that pipeline job configuration is always overwritten with no credential when a pipeline is triggered.

Also, jenkins ssh git clone always failed with "Host key verification failed" as there is no "~/.ssh/known_hosts" file. We need a way to skip the host key verification or accept it automatically. As a workaround for this particular "known_hosts" issue, we can rsh into the jenkins and the create the "~/.ssh/known_hosts" file manually.

Version-Release number of selected component (if applicable):

3.3.1.5

How reproducible:

Always

Steps to Reproduce:
1. Enable JenkinsPipeline tech preview feature
2. Create JenkinsPipeline build with Jenkinsfile on ssh git repo

Actual results:

No way to configure ssh key for Jenkinsfile on git

Expected results:

Can perform ssh git clone by adding ssh key sourceSecret to the BuildConfig of the pipeline.
