Issue

We want to be able to launch a JNLP agent using command line options, nevertheless when the agent is running others could get connection information that we would prefer to hide from a ps command execution.

Environment

• CloudBees CI (CloudBees Core) on modern cloud platforms - Managed controller
• CloudBees CI (CloudBees Core) on modern cloud platforms - Operations Center
• CloudBees CI (CloudBees Core) on traditional platforms - Client controller
• CloudBees CI (CloudBees Core) on traditional platforms - Operations Center
• CloudBees Jenkins Enterprise - Managed controller
• CloudBees Jenkins Enterprise - Operations Center
• CloudBees Jenkins Platform - Client controller
• CloudBees Jenkins Platform - Operations Center
• CloudBees Jenkins Distribution
• Jenkins LTS

Resolution

As described in one of the comments inside JENKINS-18342, we can create a file where each entry shown below must be in a different line:

params.txt

-jnlpUrl
http://somewhere/xx.jnlp
-secret
<SECRET>

Once that we save this file as params.txt we should be able to invoke the agent using the syntax shown below:

java -jar agent.jar @params.txt

Tested product/plugin versions

• CloudBees CI (CloudBees Core) on traditional platforms - Client controller 2.176.4.3
