Jenkins / JENKINS-31514 Jenkins Swarm slave goes remains offline after master restarts Issue Type: Bug Assignee: Kohsuke Kawaguchi Components: swarm-plugin Created: 12/Nov/15 9:01 AM Environment: swarm-plugin 2.0 jenkins 1.627 Priority: Minor Reporter: Choon Ming Goh I'm currently using the swarm plugin to connect all my slaves to the master. However, whenever the Jenkins service on the master gets restarted, the Jenkins slave will remain offline. It will only come back online when I restart the jenkins swarm plugin process.

Re: Jenkins Swarm slave goes remains offline after master restarts You can use a service like "supervisor" that will automatically start the swarm jar on the slave if it ever goes down. That is what we use. We have the process retry X times with a sleep of Y seconds in between each attempt. That way, we can restart our master for maintenance, and when it is back online the agents will magically re-connect.

KK does not maintain this plugin anymore. Moving to unassigned to set the expectation

Re: Jenkins Swarm slave goes remains offline after master restarts This should be working nowadays. You need to use the -deleteExistingClients so that the Swarm Client can connect after the restart. See PipelineJobTest#buildShellScriptAfterRestart for a working example from a unit test.
