Jenkins2 pipelines simple demos

Simple steps

• File: Jenkinsfile
• goes through promotion steps and wait for approve for production

Pipeline with Docker

• File: DemoPipeline
• run commands inside Docker (serverspec tests)
• for simplicity we use prebuilded centos6 with ruby2 (docker hub - volanja/docker-ruby2.2.0)
• set simple provision from attached volume (jenkins workspace mount to /code)
• just install and start Apache
• run serverspec tests (sample from http://serverspec.org/)

Docker playground with Puppet

• librarian used
• Centos6 with ruby2 and puppet - credits to Paul https://hub.docker.com/r/pauldavidgilligan/docker-centos6-puppet-ruby215/

      docker pull pauldavidgilligan/docker-centos6-puppet-ruby215
      docker build -t="centos6-puppetted" ./
      docker run -P -d -p 127.0.0.1:8081:80 --name DocPupNginx -t centos6-puppetted

Travis playground

• .travis.yml
• build docker
• run serverspec (just test listener on port 80)
