Docker slave plugin quick start



This plugin allows to execute a jenkins job inside a (set of) container(s). Jenkins job run into slave containers which linked between each other. Jenkins uses own mechanism to control build on slaves(docker slave containers). Jenkins connects to docker API (socket in our case) and API allows to control remote processes as well.



  • Docker offer isolated, customizable environment
  • We can use any image, without jenkins specific requirement
  • Compose your build like a docker-compose, linking your main container with side container(selenium for example or database)
  • Support pipelines
  • Can be used your Dockerfile in SCM (docker as a code)


How to configure Docker slaves plugin

  • Install plugin. Manage Jenkins – Manage plugins – Available – Find “Docker slaves plugin”
  • Manage Jenkins – Configure system

Remoting image – jenkinsci/slave strongly recommended

Docker host URI – docker socket on the Jenkins host


  • Access to socket for Jenkins user


On the Jenkins host type following command in bash




Check permissions



Output can be something like this



Check if everything is fine with docker API and user Jenkins



If you see something like “Can’t connect to Docker API” that something was wrong adn you have to check permission of socket or make sure docker daemon is up and running.


If you see like a list of containers it means that everything is ok and you can create job.


How to create Job with Docker slaves plugin

Create Job – Freestyle project

Открыт файл "Фотозаметка"

Choose “Run the build inside Docker containers”.  In test case I used image – maven:3.3.3-jdk-8 and side container with image – selenium/standalone-firefox.


Choose SCM – Git and define repo with test project

Define build step “Execute shell” and command mvn clean test

Открыт файл "Фотозаметка"

Eventually! You can run the Job.

Enjoy and see output!
