Introduction: Why we need this document Docker support is now known to be extended to Windows 2016 server and we can use these windows containers as slaves to a Jenkins master. It used to be jenkinsci/jenkins, then it moved into the official library as jenkins:latest, and now it's moved to jenkins/jenkins:lts.

Jenkins uses SSH to communicate with agents. Select Startup type --> Automatic. Here we use java-docker-slave; Name: Name of the docker template. Add the following lines: FROM jenkins / jenkins LABEL maintainer = "hitjethva@gmail.com" USER root Add a … This makes it simpler to reference by subsequent docker container commands. In this video, learn how to add Docker as a resource for Jenkins agent deployment. A secret file is a credential which is stored in a file and uploaded to Jenkins. In the agent program running on your agent machine, click File --> Install as Windows Service. The parameter in agent/node allows for any valid Jenkins label expression.

You can create docker file with the following command: mkdir docker nano docker / dockerfile. The "official" jenkins image on the Docker hub has moved around a few times. docker run --name myjenkins -p 8080:8080 -p 50001:50001 --env JENKINS_SLAVE_AGENT_PORT=50001 jenkins/jenkins:lts Note: This environment variable will be used to set the port adding the system property jenkins.model.Jenkins.slaveAgentPort to JAVA_OPTS.

An example of how you'd extend the upstream image looks like the below example:

For the Docker Image, use sample one which has Docker client benhall/dind-jenkins-agent. Secret files are used for credentials that are: ... Docker client certificate - to handle Docker Host Certificate Authentication. 1 ( Optional) Specifies the Docker container name for this instance of the jenkinsci/blueocean Docker image. : 2 ( Optional) Automatically removes the Docker container (which is the instantiation of the jenkinsci/blueocean image below) when it is shut down. For more information about Docker Compose, please check the Docker Documentation. I've found those definitions: node: Most work a Pipeline performs is done in the context of one or more declared node steps. The Docker Compose Build Step plugin allows the user to run docker-compose commands as build steps.

What is the difference between an agent and a node in a jenkins pipeline?. Step 6: Now, from “Docker Agent Template” dropdown, click the “Add Docker template” and fill in the details based on the explanation and the image given below and save the configuration.

In fact, running Jenkins agents in Docker containers makes plenty of sense when one considers that most applications are being deployed as containerized workloads as well.

This image is configured with a Docker client and available here. This is really useful for running through a CLI or script.

If Jenkins can run in a Docker container, why not run the agents in containers as well? That occurred to me as the way to go were I to use jenkins script and spin up containers via bat or sh calls to docker, however, I am not sure how this would work or if you can even do this using the declarative pipeline agent syntax. This keeps things tidy if you need to quit Jenkins. ; agent: The agent directive specifies where the entire Pipeline, or a specific stage, will execute in the Jenkins environment depending on where the agent directive is placed. For this image we'll derive from our Java JRE base image, but this time we don't have to fetch a .jar or .war file from the internet. Create a Jenkins agent image.

Find Jenkins Agent in the list, Double click to open.

It will be used in the Job configuration. Note that this feature requires ".Net Framework 3.5" Start, type Services and Select the Services program. A Jenkins agent image can be created and connected headless later on.

Next, you will need to create a docker file to pull and build Jenkins image with required settings. To enable builds to specify Docker as a build agent, set a label of docker-agent. Labels – Identification for the docker host.
