At the time of writing this article, the current version is 8.5.50. Find “ Core” and download the Tomcat binary. Go to /opt directory, in your tomcat_container: /]# cd opt/ To install Tomcat in your Centos container, follow the steps: $ docker exec -it eca291a36127 /bin/bash

To run the container from the pulled image in detached mode, use the command below: $ docker run -dit -name tomcat_container -p 8888:8080 centosĪs Jenkins has already occupied port 8080 on the machine, here we have opened port 8888 for Tomcat in spite the default port being 8080. Status: Downloaded newer image for centos:latest You can also use tomcat image as per your choice, however for this guide we are going to stick to the plan. For this, we are going to use CentOS, which will enable us to set up a customized Tomcat server. Now, it’s time to spin the Tomcat container. If everything goes well, you will land on the Jenkins’ dashboard area, which looks something like this: Tomcat Set up Jenkins will install all the necessary plugins. Next, run the initial setup wizard and select Recommended Plugins. To extract the Jenkins password from Jenkins’s container, you can run below-mentioned command: $ docker exec -it jenkins_container cat /var/jenkins_home/secrets/initialAdminPasswordĬopy the admin password from your terminal and open in your preferred browser.

You can see the running container here: $ docker psĬONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESĬe46107c9f83 jenkins/jenkins:lts '/sbin/tini” Up 1 minutes Up 1 minutes 0.0.0.0:8080->8080/tcp jenkins_container $ docker container run -dit -p 8080:8080 -v /var/run/docker.sock:/var/run/docker.sock -v /data/jenkins/jenkins_home:/var/jenkins_home -name jenkins_container jenkins/jenkins You can spin up a Docker container using the Jenkins image. This guide is assuming that you already have basic knowledge of Docker and Docker is up and running on your host machine. We will install and set up Tomcat and Jenkins using Docker, and thereafter we are going to create a Jenkins Job to deploy your Java application over the Tomcat server. In this guide, we are going to use Docker to configure Jenkins and Tomcat to achieve Continuous Integration/Continuous Deployment.
