What Operating System are you using (both controller, and any agents involved in the problem)?

Controller: Kubernetes via Jenkins Kubernetes Operator
Agent: Ubuntu 22.04 LTS

Reproduction steps

1. Use the UI to create a template to launch an Azure VM agent.
2. Export via JCasC view of configuration
3. Launch Jenkins with the new JCasC applied

Expected Results

The configuration contains the launcher: ssh setting.

Actual Results

The configuration is missing the launcher: ssh setting. Launching the agent fails.
Launching only seems to work after manually validating the template once after the JCasC is applied.

Anything else?

Eventually, #567 is still happening for me.

Are you interested in contributing a fix?

Not sure I am able to.

[BenjaminHerbert]

The launching seems to fail due to (an additional) different problem.

[timja]

What problem? I wasn’t able to get it to export for some reason but it should default to SSH now
