We will use vfc-nfvo-lcm(python project) as a sample to describle how to build docker image for vfc components.
- write a Dockerfile
1) create a directory named docker in base repo( you can ref to vfc/nfvo/lcm/docker )
2) In the docker directory, you need add the following files( you can ref to vfc/nfvo/lcm/docker/* )
build_image.sh note: the file is called by script in jjb of ci-management
docker-entrypoint.sh note: the file is used as ENTRYPOINT of Dockerfile
Dockerfile note: the file is used by docker build command(if the repo is a java project, you should add jdk and tomcat in apt-get install)
instance_config.sh note: this file is called by docker-entrypoint.sh to config parameters when docker is created.
instance_init.sh note: this file is called by docker-entrypoint.sh to do one-time initialization when docker is created.
instance_run.sh note: this file is called by docker-entrypoint.sh to start your service when docker is created.
LICENSE note: because we do not add license header in the above sh files, so we need add this license file.
node: before you commit your file, you should use "git update-index --chmod=+x <file>" command to add execute permission to the above sh files.
and you can use "git ls-files --stage <file>" to confirm the <file>'s execute permission.(note 100755 is ok, while 100644 is not ok) - create jjb in ci-management
1) enter ci-management/jjb/vfc
2) add build-<name>-docker-image.sh( you can ref to build-nfvo-lcm-docker-image.sh)
3) add docker-java-version-shell-daily to ymal file( you can ref to vfc-nfvo-lcm-java.yaml)
- '{project-name}-{stream}-docker-java-version-shell-daily':docker-pom: 'pom.xml'
mvn-goals: 'install'
script:
!include-raw-escape: 'build-nfvo-lcm-docker-image.sh' - Add a version.properties file in your base repo(ref to vfc/nfvo/lcm/version.properties)
- execute docker-java-version-shell-daily job immediately
Enter "please release" in your reply to your commit in gerrit. - confirm docker file in nexus3.onap.org
Open https://nexus3.onap.org and input your image name in the "Search components" text box. ref the following:
