CI/CD GitHub Action 🚀

A CI/CD workflow for your maven project!

Getting Started

This is an example of building a CI & CD pipeline using GitHub actions.

The CI pipeline depends on maven to compile and test the project's code. JPA/MySQL is supported.

The CD pipeline will create a docker image of the project's code and deploy the image as a docker container along with a MySQL container on a remote server using SSH. The bridge driver of docker networks connects these containers.

In the docker-compose.yml, you can configure the tag of the images. By default, the tag of the project is dev. However, you can change the tag to a specific version to control the deployment. The workflow supports tags in the sem-version format like v*.*.*.

To create a new release using a specific tag, navigate to your GitHub repository. Go to tags -> create new release -> publish the release.

Prepare the production server

1. Connect to your server

   ssh -i <private key path> <user>@<host>

2. Add environment variables

   echo "MYSQL_ROOT_PASSWORD=myrootpw
   MYSQL_DATABASE=mydb
   MYSQL_USER=myuser
   MYSQL_PASSWORD=mypw
   DOCKER_IMAGE_NAME=ci-cd
   GITHUB_USER=mathiasreker" >~/.env

   MYSQL_ROOT_PASSWORD, MYSQL_DATABASE, MYSQL_USER and MYSQL_PASSWORD can be anything.

   DOCKER_IMAGE_NAME must match the name of the docker image defined in workflow.

   GITHUB_USER must be the user/organisation of the repository in lower case.

This script replaces step 3-6 (optional)

bash <(curl -s https://raw.githubusercontent.com/MathiasReker/Java-CI-CD/develop/install.bash)

3. Install docker-compose

   sudo apt-get update && sudo apt-get install -y docker-compose

4. Generate a new key named github-actions with an empty password

   ssh-keygen -t rsa -b 4096 -f ~/.ssh/github-actions -q -P ""

5. Copy the content of github-actions into authorized_keys

   cat ~/.ssh/github-actions.pub >>~/.ssh/authorized_keys

6. Grab the private key, as you will need it soon

   cat ~/.ssh/github-actions

Install action secrets

Navigate to your GitHub repository. Go to settings -> secrets -> actions.

Add the following secrets:

• SSH_USER
• SSH_HOST
• SSH_PRIVATE_KEY

Install the workflow to your project

1. Copy the workflow to this path of your repository: /.github/workflows/ci-cd.yml.

2. Copy the docker-compose.yml to the root folder of your project.

3. Copy the Dockerfile to the root folder of your project.

Depending on your project, it is necessary to adapt the docker-compose.yml and the Dockerfile.

Package visibility

To see the package, the CD pipeline must run at least once. The pipeline will create a package linked to your GitHub repository.

Navigate to your GitHub repository. Go to the package -> select package settings -> select danger zone -> change visibility -> make it public.

Usage

The CI pipeline is triggered on any change to the code on your repository.

The CD pipeline is triggered on push events. The CD pipeline will be skipped if the CI pipeline fails.
