Trigger a Remote Jenkins Job with parameters and get console output in real time, as well as result (pass/fail)

Background

This script is intended to replace the Jenkins Parameterized Remote Trigger Plugin.

At the time of writing this, the plugin appears unmaintained and the last commit was sometime in August, 2015. Recent Jenkins updates have made this plugin extremely unstable, resulting in frequent NullPointerError failures.

Requirements

jq, curl, Jenkins

Usage

Extremely simple, use as follows:

remote-job.sh -u https://jenkins-url.com -j JOB_NAME -p "PARAM1=999" -p "PARAM2=123" -t BUILD_TOKEN -i

Where the following parameters are set:

  • -u: url of jenkins host
  • -j: JOB_NAME on jenkins host (eg master-build).
  • -p: parameter(s) to pass in. Send multiple parameters by passing in multiple -p flags.
  • -t: BUILD_TOKEN on remote machine to run job
  • -i: ignore certificate validation (useful if you see curl SSL errors while polling)

You can optionally set the polling interval (POLL_INTERVAL, default 5) and build timeout (BUILD_TIMEOUT_SECONDS, default 3600) as environment variables.

The script will poll the job until completion, and output the console of the running job in near-real time as it is updated. It does this by setting a cursor on the last line received and only outputting new lines (using a simple tail -n command).

Notes

Currently the script outputs all parameters (including tokens) for logging purposes. You may want to implement a mask on any sensitive fields like tokens through Jenkins password fields.
