SUMMARY

• Created the project stamp-devops-poc in OW2 gitLab repository (https://gitlab.ow2.org/stamp/stamp-devops-poc/tree/master) (Daniele Gagliardi Issue stamp/h2020#94)

• Created a project to tests GitLab CI/CD (Nicola Bertazzo Issue stamp/h2020#95). Installed and configured a docker GitLab Runner (Martin Hamant Issue stamp/h2020#96)

• Created the file .gitlab-ci.yml to configure the continuous integration delivery process (Nicola Bertazzo Issue stamp/h2020#95).

• Tested the continuous integration process that contains these steps:

  • build: executes mvn clean compile command into a container based on maven:3.3.9-jdk-8 image
  • test: executes mvn test command into a container based on maven:3.3.9-jdk-8 image
  • package: executes mvn package into a container based on maven:3.3.9-jdk-8 image
  • int-test: executes mvn verify into a container based on maven:3.3.9-jdk-8 image

• Tested the CI process localy using this command:

gitlab-runner exec docker package

• Tested CI process remotely.

Troubles solved:

• cache .m2/repository to avoid to download for every steps all the maven dependency (https://gitlab.com/gitlab-org/gitlab-ce/issues/15167). Added this parameter to MAVEN_OPTS variables

MAVEN_OPTS: -Dmaven.repo.local=/cache/maven.repository

Troubles not solved:

• Run docker build in dind: Cannot connect to the Docker daemon problem (https://docs.gitlab.com/ce/ci/docker/using_docker_build.html)
• Store variables from maven execution (p.es. version, etc)

Next steps:

• build and deploy a docker image into a docker registry:
  • Define a step to build docker image (https://docs.gitlab.com/ce/ci/docker/using_docker_build.html)
  • Define a step to test docker image
  • Configure a GitLab Container Registry (https://about.gitlab.com/2016/05/23/gitlab-container-registry/) @mh
  • Define a step to deploy the image in the docker registry
  • Use the docker image sotred in the docker registry to create a container
