I have been looking a lot on Google on how to install the service in command line (so without manual interaction) but I am stuck on how to get the jenkins-slave.exe
I found those instruction https://wiki.jenkins.io/display/JENKINS/Installing+Jenkins+as+a+Windows+service but I can't figure how to get the executable. I have downloaded and run the slave.jar with the right key, which connects the slave, but the exe is not generated.
I found this page https://github.com/kohsuke/winsw/blob/master/doc/installation.md#winsw-installation-guide to install it manually but that sounds like re-invented the wheel when the jar can do it. Plus there is a risk the WinSW.exe is different and doesn't get updated by the plugin (I saw some automatic update code in it).
So is there a way I can download the jenkins-slave.exe or generate it? or is there a way to run the "Install as a service" in command line from the slave.jar?
To answer my own question, after having contacted the plugin developers:
There is no actual way to download the exe from Jenkins directly, the slave.jar gets it from the master via the remoting protocol. I have created a request to be able to download it via an URL (as suggested by the developer), so it might be available in the future.
Right now the executable is a renamed Windows Service Wrapper binary: https://github.com/kohsuke/winsw so I used this binary the same way.
Regarding the configuration used by WinSW and XML files, I used the one from the GitHub repository https://github.com/jenkinsci/windows-slave-installer-module. The versions are compatible in terms of the configuration.
So basically I download the exe, get the private key from Jenkins and create the service using the configuration from the original plugin. Then I install the service using jenkins-slave.exe install
.
Step by step:
java -jar slave.jar -jnlpUrl http://jenkins...
slave.jar
file from Jenkins (gotten from the JNLP command)http://repo.jenkins-ci.org/public/com/sun/winsw/winsw/2.1.0/winsw-2.1.0-bin.exe
winsw-2.1.0-bin.exe
into jenkins-slave.exe
jenkins-slave.exe install
