I will be delivering this online course for O’Reilly media, October 18, 2016 7:00pm CEST

Scaling Jenkins with Docker and Apache Mesos

Continuous integration and continuous delivery at scale

Join Carlos Sanchez for a study in running Jenkins at scale. He’ll share his experience using Docker and Apache Mesos to create one of the biggest Jenkins clusters to date. You’ll drill down into the details with Carlos to get a better understanding of how Apache Mesos works. Together you’ll explore the challenges of running containerized and distributed applications (particularly JVM ones) through a real-world use case. By the end of this course, you’ll have a solid grounding in using these popular open source technologies for continuous integration and continuous delivery at scale.

What you’ll learn—and how you can apply it

By the end of this live, online course, you’ll understand:

  • How Apache Mesos works and how Docker containers are executed in a Mesos cluster
  • How Jenkins can use a Mesos cluster as a provider to provision build agents on demand
  • How Java applications behave inside a Docker container

And you’ll be able to:

  • Create a Apache Mesos cluster for local development using Docker Compose
  • Create Jenkins jobs that are executed dynamically based on demand
  • Use Jenkins Pipelines to execute jobs in one or more Docker containers

This course is for you because…

  • You’re a build/release engineer or are interested in deploying Docker at scale
  • You work with Jenkins or other Java applications
  • You want to become a Docker expert!

JavaOne: From Monolith to Docker Distributed Applications

I’ll be speaking again this year at JavaOne: From Monolith to Docker Distributed Applications, sharing our experience running the Jenkins platform on Docker containers using Apache Mesos.

You can also find me in the CloudBees booth in the exhibitors area.

Docker is revolutionizing the way people think about applications and deployments. It provides a simple way to run and distribute Linux containers for a variety of use cases, from lightweight virtual machines to complex distributed microservice architectures.

But migrating an existing Java application to a distributed microservice architecture is no easy task, requiring a shift in the software development, networking, and storage to accommodate the new architecture.

This presentation provides insights into the experience of the speaker and his colleagues in creating a Jenkins platform based on distributed Docker containers running on Apache Mesos and Marathon and applicable to all types of applications, especially Java- and JVM-based ones.

Docker is revolutionizing the way people think about applications and deployments. It provides a simple way to run and distribute Linux containers for a variety of use cases, from lightweight virtual machines to complex distributed micro-services architectures. Kubernetes is an open source project to manage a cluster of Linux containers as a single system, managing and running Docker containers across multiple Docker hosts, offering co-location of containers, service discovery and replication control. It was started by Google and now it is supported by Microsoft, RedHat, IBM and Docker Inc amongst others. Jenkins Continuous Integration environment can be dynamically scaled by using the Kubernetes and Docker plugins, using containers to run slaves and jobs, and also isolate job execution.

Scaling Docker with Kubernetes V1

My latest article at InfoQ, covering Kubernetes v1, Google Container Engine, Jenkins at scale and the Jenkins Kubernetes plugin.

It’s been a while…

I’ve been neglecting the blog, mostly because I was writing already a lot for InfoQ and joined CloudBees in April,to work on scaling the Jenkins platform with a product called “Tiger” that will be released soon (using Docker, Mesos, Marathon,… a LOT), I really need to write something about it.

Plus, a lot of conference traveling and some speaking:

All the conference coverage is at my Lanyrd page

AnsibleLogoAn example of downloading artifacts from a Maven repository using Ansible, including a prebuilt Docker image.

Prerequisites

Install JDK and Maven using existing Ansible modules

ansible-galaxy install geerlingguy.java
ansible-galaxy install https://github.com/silpion/ansible-maven.git

- hosts: localhost

 roles:
 - { role: ansible-maven }
 - { role: geerlingguy.java }

 vars:
 java_packages:
 - java-1.7.0-openjdk

Example

From mvn.yml, download any number of Maven artifacts optionally from different repositories

- hosts: localhost

 vars:
 mvn_artifacts:
 - id: org.apache.maven:maven-core:2.2.1:jar:sources
 dest: /tmp/test.jar
 # params: -U # update snapshots
 # repos:
 # - http://repo1.maven.apache.org/maven2
 
 tasks:
 - name: copy maven artifacts
 command: mvn {{ item.params | default('') }} org.apache.maven.plugins:maven-dependency-plugin:get -Dartifact={{ item.id }} -Ddest={{ item.dest }} -Dtransitive=false -Pansible-maven -DremoteRepositories={{ item.repos | default(['http://repo1.maven.apache.org/maven2']) | join(",") }}
 with_items: mvn_artifacts

Docker

An image with Ansible, JDK and Maven preinstalled is available at csanchez/ansible-maven.

Scaling Docker with Kubernetes

Reply

kubernetesI have published a new article on InfoQ, Scaling Docker with Kubernetes, where I describe the Kubernetes project and how it allows to run Docker containers across multiple hosts.

Kubernetes is an open source project to manage a cluster of Linux containers as a single system, managing and running Docker containers across multiple hosts, offering co-location of containers, service discovery and replication control.

Included in the article there is an example of scaling Jenkins in a master – multiple slaves architecture, where the slaves are running in Kubernetes. When I finally find the time I will implement a Jenkins Kubernetes plugin that would handle the scaling automatically.
