Hi Guys,

I want to create one cluster of Jenkins. So I am trying to implement this task on Docker. Can anyone help me, how can I create Jenkins image?

Hi@akhtar,

You can pull Jenkins image from docker hub. But if you want to create a customize image of Jenkins, you can use Dockerfile. Here I have attached one Dockerfile for your reference.

FROM centos:7
RUN  yum install wget -y
RUN yum install java-11-openjdk.x86_64 -y
RUN wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
RUN rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
RUN yum install jenkins -y
RUN yum install /usr/sbin/service -y
EXPOSE 8080
RUN yum install sudo -y
RUN echo "jenkins ALL=(ALL) NOPASWD: ALL" >> /etc/sudoers
RUN yum install iptables -y
ENTRYPOINT service jenkins restart && bash

Hope this will help.
