jenkins-cli commands returning connect timed out

问题

Any suggestions/fixes for this jenkins-cli error?

I have a deploy job, which is parameterized (test, stage, prod). So, whenever there is a deploy to the "staging" environment, i am trying to make Jenkins slaves execute a groovy script. Trying to test the jenkins-cli.jar, i got this error:

[jenkins@ip-10-0-0-92 scripts]$ java -jar jenkins-cli.jar -s https://my_jenkins_URL/ help

I have done:

Set a fixed port for TCP/IP port for CLI and slaves & its listening on the master server
All ports are open between the jenkins nodes
Went through https://wiki.jenkins-ci.org/display/JENKINS/Jenkins+CLI

I am using nginx with valid SSL cert.

PS: i came accross the below 2 questions. they are close but none have a solution and the issues are unique in its own ways.

How to have jenkins-cli.jar work with Jenkins running https? Jenkins CLI with HTTPS

回答1:

I got the same error and fixed it by adding a new entry in /etc/hosts file.

The line I added is:

10.0.0.11 jenkins.xxxxx.com

The issue is that the slave couldn't resolve the Jenkins master. This has been happening since I set up a new server for my Jenkins master.
