Add a script to create and configure a dedicated Jenkins agent user on a VM

[sony-level]

Hi,

I’d like to propose adding a Bash script to help prepare a test server or VM to be used as a Jenkins SSH agent/node.

The script would:

• create a dedicated Linux user for Jenkins, for example jenkins
• create and secure the user’s .ssh/authorized_keys
• allow adding the controller public key plus optional extra public keys
• install Java if it is missing
• optionally add the user to the docker group
• lock the user password after setup

This would be useful for teams that want to turn a test VM into a Jenkins agent quickly and consistently.

The project already contains many Jenkins-related scripts, so this would fit well alongside the existing Jenkins utilities.

Suggested file name:

• jenkins/setup_jenkins_agent_user.sh
  or
• jenkins/jenkins_setup_agent_user.sh

If helpful, I can also contribute the script itself in the same style as the existing Bash tools.

came across DevOps-Bash-tools while looking for something in this space the test coverage gives a lot of confidence. I checked and the tests actually test meaningful behavior, not just that functions don't throw the database layer is well abstracted. query building is intuitive and the connection pooling just works without configuration every time I think I've seen all the good parts I discover something else that's been handled really well. the depth here is impressive.

idk who designed the api but they clearly actually use their own product. everything is where you'd expect it to be. refreshing.

just shared this with my team, everyone loved it

the codebase is surprisingly readable for something this complex. needed to dig into the source for a custom thing and it was actually pleasant.

would love this. right now i have to use a separate tool just for this one thing
