Jenkins talking to another Jenkins instance

[Seth Floyd]

I currently have 2 Jenkins instances. One does our deployments and the other does automated testing. Is there a way to send a notice from Jenkins1 to Jenkins2 once a build has completed successfully to automatically kick off automated testing jobs?

(Before im berated with questions about why we are setup this way...I didn't do it, im just fixing and working with what I was brought in to deal with)

Thanks.

This is something that we need to do as well.  We have Jenkins instances distributed globally and in one case, we need to trigger jobs remotely on other Jenkins instances.

What we do is have the remote job trigger set to "Trigger builds remotely" with a specific authentication token.  On the local machine, we execute a "curl" command to the remote job's URL, passing the authentication token and an additional parameter.

# Start the build
curl $JOB_URL/buildWithParameters?token=AUTH_TOKEN\&myParm=abcd
if [ ! "$?" = "0" ]; then
    exit 1
fi

We then use curl with json to poll the remote job for status.  If you only care about triggering the job and not the status, you can skip this part.

# Poll every sixty seconds until the build is finished
JOB_STATUS_URL=${JOB_URL}/lastBuild/api/json
while [ $GREP_RETURN_CODE -eq 0 ]
do
    sleep 60
    # Grep will return 0 while the build is running:
    curl --silent $JOB_STATUS_URL | grep result\":null > /dev/null
    GREP_RETURN_CODE=$?
done

Just to clarify, by "Status" in this case, I am checking to see when the remote job has completed, not the actual end result of the job (success/failure/unstable).

Have you tried https://wiki.jenkins-ci.org/display/JENKINS/Parameterized+Remote+Trigger+Plugin to trigger the remote job?

I haven't used it yet so it may not work for your needs, but it is configured as a build step so I believe it blocks until the step completes which would allow you to wait before proceeding to the next step/job for testing.

That looks like it would do the job.  Our jobs predate this plugin so we had to use what was available at the time.

From the number of installations for this plugin, it seems that we are not alone in needing this capability... ;-)

Has anyone seen an issue where when you go to add the post-build action in your job the option for "trigger a remote parameterized job" is not in the list even though the  plugin is installed?
