Java Continuous Delivery by Docker

Continuous delivery demo that aims to use following principles:

• immutable environments
• short lived environments
• built and destroyed for each git commit

Continuous delivery with Jenkins (on-prem)

E2E with Docker Compose and Maven

Stack

Technology	Version
Java	8
Wildfly	10.1.0
MySQL	5.7
Maven	3.5
Docker	1.10
Docker Compose	1.6

Continuous delivery with Jenkins

• Start continuous delivery stack
• Create jenkins plan
  • $ cd jenkins && ./createJob.sh localhost bookstore config.xml
• http://localhost:8088/job/continuous-delivery -> 'Build Now'

Continuous Delivery life-cycle

• Source code changes pushed to git
• Jenkins detects changes and starts job
  • Build war/jar artifact
  • Start stack (includes image build for java web app)
  • Apply db schema (flywaydb.org)
  • Execute integration tests
  • Stop stack (includes destroy of web and database containers)

E2E with docker compose and Maven

• Step-by-step

    $ TAG=dev docker-compose up -d ackris-db ackris-web                     # start web and database containers
    $ mvn clean compile flyway:migrate                                      # deploy database schema
    $ mvn clean verify -Dmaven.test.failure.ignore=false -Dtest.port=8070   # run integration tests

Use -Dmaven.buildNumber.doCheck=false if project contains local changes
