Im writing the script which downloads jenkins war, skip setup, then install plugins for it.
i downloaded batch-install-jenkins-plugins.sh using some link, and also created the plugins.txt file as mentioned.
when i run the script using docker it is giving me error that you must specify plugins.txt.
Here is my script:

FROM ubuntu:14.04

when i build the image of above script it is giving this error:

You must provide plugin file
usage: batch-install-jenkins-plugins.sh options

Install or update Jenkins Plugins.

OPTIONS:
-p --plugins file containing plugins list
-x --xplugins file containing excluded plugins list
-d --plugindir directory where to deploy plugins (.jpi)

Examples:

Run:batch-install-jenkins-plugins.sh --plugins okplugins --excludedplugins nokplugins --plugindir /var/lib/myjenkins/plugins
The command '/bin/sh -c xargs /usr/local/bin/batch-install-jenkins-plugins.sh < /usr/share/jenkins/ref/plugins.txt' returned a non-zero code: 123

FOR checking if i comment that line and changed ENTRYPOINT to bash and checked, and found plugins.txt is present in that location only
BASH OUTPUT

I need to take arguments from plugins.txt and install those plugins to jenkins, when i launch it in browser.

i refered to the link

Thank you in advance, sorry if there wrong english.

xargs works by creating a new command line an running it. The way it creates the command line is by starting the new command line it is creating with the arguments given as the xargs command line and then appending the biggest chunk of stdin that it can (remember that if stdin is bigger than the maximum command line length will make it impossible to simply use all of stdin, it must be chopped up to fit inside of valid maximum command line length.)

The script, batch-install-jenkins-plugins.sh, (I got mine from here, you should have provided the link to where you got yours from because there could be many variants of that script) does nothing to provide the -p option so it dies with missing -p pluginfile.txt.

RUN xargs /usr/local/bin/batch-install-jenkins-plugins.sh < /usr/share/jenkins/ref/plugins.txt


Are you sure you should even be using xargs here at all? I think this is what you are really trying to do:

RUN /usr/local/bin/batch-install-jenkins-plugins.sh -p /usr/share/jenkins/ref/plugins.txt


But then you will probably crash because of missing -z plugindir option which you should also add to your Dockerfile.

Go to below link, which I found similar what you have asked

You can refer this

I am not exactly sure what is wrong with your build, but your Jenkins Dockerfile looks unnecessarily complicated. Here is a simple Dockerfile that does what you want:

FROM jenkins/jenkins:lts

COPY plugins.txt /usr/share/jenkins/ref/plugins.txt

RUN /usr/local/bin/install-plugins.sh < /usr/share/jenkins/ref/plugins.txt

That installs the plugins defined in plugins.txt.

This should be enough to install your plugins automatically. However if you want to configure a complete Jenkins instance from a configuration file, check out this Jenkins plugin that allows Jenkins to be completely configured from YAML.
