Docker based Continuous Integration Containers

Pre-Requisites

• Docker (for Mac OSX / Windows / Docker)
• Docker Compose
• Clone the repository

QuickStart

• To Start containers in the background

  $ docker-compose up -d

• Stoping all containers

  $ docker-compose down

The result of the compose is multi-fold

• Build Jenkins with Java8,Maven 3 , Nexus , Postgres , SonarQube (5.6.x) and Nginx Images

• Start the respective containers with port mapping

• Configure SonarQube with Postgres

• Mount docker volumes for persisting the changes done at container level

• Configure nginx reverse-proxy with urls relative to localhost

• Jenkins: http://localhost:8080/jenkins/

• Nexus: http://localhost:8080/nexus/

• Sonar: http://localhost:8080/sonar/

"Unlock Jenkins" - Initial Access

$cat /var/jenkins_home/secrets/initialAdminPassword

Copy and Paste the Value into Unlock Screen in Jenkins Web Console

To Start Individual Application Containers

Jenkins

docker run --name jenkins -p 10001:8080 -p 50000:50000 -d jenkins-jdk8 --prefix=/jenkins/

Nexus

docker run -d --name nexus-db sonatype/nexus /bin/true docker run -e "CONTEXT_PATH=/nexus" -d -p 10002:8081 --name nexus --volumes-from nexus-db sonatype/nexus

Sonarqube (with Postgres DB):

docker run -d --name postgres-volume postgres /bin/true docker run -d -e "SONARQUBE_WEB_CONTEXT=/sonar" --name sonarqube -p 10003:9000 -p 9092:9092 sonarqube "-Dsonar.web.context=/sonar" docker run -d --name postgres --volumes-from postgres-volume -e "POSTGRES_USER=sonar" -e "POSTGRES_PASSWORD=sonar" --net container:sonarqube postgres

Nginx based Proxy:

docker run --name proxy --link jenkins --link nexus --link sonarqube -d -p 8080:80 -d proxy
