Continuous Deployment Automation : Git -> Jenkins -> Docker

DevOps - continuous deployment automation using Git, Jenkins & Docker

Create a Git repository ->

Create a Dockerfile (- to build a container for a php web application shown above in video as an example) inside the Git repository ->

Create other components (index.php under src folder in above example) in the git repository needed to run the designated application inside a docker container -> Change one of these components to git commit the change and trigger a Jenkins build ->

Create a Jenkins freestyle project in Jenkins -> Update the above created Git repository location under SCM configuration of the project -> Select trigger builds remotely and input an authorization token in the configuration ->

Update .git/hooks/post-commit file with a syntax to trigger the Jenkins job created in above step -> Update .git/hooks/post-commit file with a syntax to execute docker commands to create and run a docker container using a Dockerfile ->

Docker commands can be put in an executable file (buildExecutable in this case) ->

Commit the change made (-in one of above steps) in application component -> post-commit of .git/hooks folder will trigger the Jenkins build job -> post-commit will also execute docker commands to build and run a docker container running an application within (a php web application in this case).
