Project 1 : Build a Docker Image for Sysfoo

Link to Application Source: https://github.com/schoolofdevops/sysfoo

Description:

Sysfoo is a java based web application, which uses maven as a build tool. The build specifications are provided with pom.xml in the root directory of the project. Your job is to write a dockerfile to build and package the sysfoo application.

The instructions to build this project is as follows:

  • maven and jdk should be installed as part of build tool/ container
  • the source files should be copied to the workdir
  • project can be compiled and packaged with mvn package command
  • the above command creates a .war file which needs to be part of the final image
  • this warfile can be deployed with tomcat. Specifically, it should be copied to the webapps directory of tomcat
  • image should contain all relevant metadata e.g. port to expose, command to launch etc.

Instructions:

  • Image should have a automated build on DockerHub. E.g. whenever the code is updated in the repo, it should build a new version of the image automatically.
  • Final deliverable image should contain only tomcat along with .war file. It should not contain the build tools e.g. maven

Deliverables:

  • Link to github repo with application code, Dockerfile etc.
  • Link to the page where image is published e.g. DockerHub

Project 2 : Deploy a Microservices Stack with Docker SWARM

Link to Application Source: https://github.com/microservices-demo/microservices-demo

Description:

As a Devops Ninja, you have been tasked with deploying microservices based Sock Shop application in production. You are to also setup monitoring services once the application is deployed.

Instructions:

  • Setup a SWARM cluster. Should have minimum of 3nodes. Ideally 5 nodes with 3 masters. You could also use http://play-with-docker.com to do so.
  • Examine the Microservices Demo app, its deployment scripts. Learn how its been designed, what are the components, how they are connected with each other etc.
  • Examine the swarm deployment scripts, convert it into version 3. Add deploy configurations etc.
  • Deploy the application on the cluster built above.
  • Scale the application components, do rolling updates etc.

** Deliverables**:

  • Link to git repo which contains your own fork of the Microservices App. It should also contain deploy stack definition for swarm with version 3, overlay network etc.
  • Screenshot of the visualizer for docker swarm after building cluster and deploying the application.
