How to install Jenkins plugins automatically with docker using the input text file?

Question

I'm trying to install the Jenkins plugins before I launch it on the server. In my code I have installed java, maven, git etc, then  downloads Jenkins.war which I can launch it in the server using "docker run -p 8080:8080 <image>"

Then I thought of installing plugins before I launch it, and a written script that downloads install the plugin.sh, file and copies plugin.txt file to .sh and make install.

Here is my code,

FROM ubuntu:14.04

# Install Java.

RUN \

  echo oracle-java8-installer shared/accepted-oracle-license-v1-1 select true | debconf-set-selections && \

  apt-get update && \

  apt-get upgrade -y && \

  apt-get install -y  software-properties-common && \

  add-apt-repository ppa:webupd8team/java -y && \

  apt-get update && \

  apt-get install -y oracle-java8-installer && \

  rm -rf /var/lib/apt/lists/* && \

  rm -rf /var/cache/oracle-jdk8-installer

# Define commonly used JAVA_HOME variable

ENV JAVA_HOME /usr/lib/jvm/java-8-oracle

# get maven 3.2.2 and verify its checksum

RUN wget --no-verbose -O /tmp/apache-maven-3.2.2.tar.gz http://archive.apache.org/dist/maven/maven-3/3.2.2/binaries/apache-maven-3.2.2-bin.tar.gz; \

echo "87e5cc81bc4ab9b83986b3e77e6b3095 /tmp/apache-maven-3.2.2.tar.gz" | md5sum -c   

ARG BASE_URL=https://apache.osuosl.org/maven/ven-3/${MAVEN_VERSION}/binaries

# install maven

RUN tar xzf /tmp/apache-maven-3.2.2.tar.gz -C /opt/; \

  ln -s /opt/apache-maven-3.2.2 /opt/maven; \

  ln -s /opt/maven/bin/mvn /usr/local/bin; \

  rm -f /tmp/apache-maven-3.2.2.tar.gz

ENV MAVEN_HOME /opt/maven

# Install dependencies

RUN apt-get -y update  && \

apt-get -yqq --no-install-recommends install bash git bzip2 curl unzip && \

apt-get update

# copy jenkins war file to the container

#ADD http://mirrors.jenkins.io/war-stable/2.107.1/jenkins.war /opt/jenkins.war

COPY jenkins.war /opt/jenkins.war

ENV JENKINS_HOME /jenkins

# configure the container to run jenkins, mapping container port 8080 to that host port

RUN mkdir /jenkins/

COPY proxy.xml /jenkins/proxy.xml

COPY config_updated.xml opt/config_updated.xml

COPY settings.xml /usr/share/maven/conf/settings.xml

ENTRYPOINT ["java","-jar","/opt/jenkins.war"]

ENV JAVA_OPTS="-Djenkins.install.runSetupWizard=false"

#Install plugins

RUN cd /usr/local/bin && curl -L https://raw.githubusercontent.com/hgomez/devops-incubator/master/forge-tricks/batch-install-jenkins-plugins.sh -o batch-install-jenkins-plugins.sh

RUN chmod +x /usr/local/bin/batch-install-jenkins-plugins.sh 

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

RUN /usr/local/bin/batch-install-jenkins-plugins.sh --plugins /usr/share/jenkins/ref/plugins.txt --excludedplugins /noplugins.txt --plugindir /var/lib/myjenkins/plugins

RUN echo 2.0 > /usr/share/jenkins/ref/jenkins.install.UpgradeWizard.state

THis is what im getting.(below image)

TO check I changed entry point to bash and checked, this is what I have in the container.

Everything I have in the container, but it's not working.

IN the line RUN /usr/local/bin/batch-install-jenkins-plugins.sh --plugins /usr/share/jenkins/ref/plugins.txt --excludedplugins /noplugins.txt --plugindir /var/lib/myjenkins/plugins

What path should I specify in --plugindir i.e what sholud be there in that plugins??

As far as I remember, the 'install-plugin.sh' file does not accept text file. So, you can try something like below.

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

feed out put of plugins.txt file to the .sh file

Did this before itself, same error. i tried now also, same as first image in my question

can you post the error message, instead of the image? the image is not much clear.

Step 21/24 : COPY /plugins.txt /usr/share/jenkins/ref/plugins.txt
 ---> Using cache
 ---> 04430be725b7
Step 22/24 : RUN /usr/local/bin/batch-install-jenkins-plugins.sh --p /usr/share/jenkins/ref/plugins.txt
 ---> Running in 56cf131ce2e0
You must provide plugin directory
  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
/usr/local/bin/batch-install-jenkins-plugins.sh: illegal option -- -
The command '/bin/sh -c /usr/local/bin/batch-install-jenkins-plugins.sh --p /usr/share/jenkins/ref/plugins.txt' returned a non-zero code: 1

---

I meant, execute this code

RUN /usr/local/bin/batch-install-jenkins-plugins.sh --plugins /usr/share/jenkins/ref/plugins.txt --excludedplugins /noplugins.txt --plugindir /var/lib/myjenkins/plugins

and post the error.

because of the above error, it's clear that it's asking for a plugin directory.

---

that is what im getting, may be --plugindir  /var/lib/myjenkins/plugins is not allowing to run, as i mentioned in question end what should be there in /var/lib/myjenkins/plugins????????

---

Can i have more light on the command "batch-install-jenkins-plugins.sh --plugins okplugins --excludedplugins nokplugins --plugindir /var/lib/myjenkins/plugins" ?? for more knowledge for me

Hi Hitesh,

We do not know what is the content in the 'batch-install-jenkins-plugins.sh' file. It looks like its customized file.

So, if you can ask a separate question with content of 'batch-install-jenkins-plugins.sh' file. The command you are executing and the error that you are getting, We can answer your question quickly.
