Many web makers still update sites by hand and face errors. GitHub Actions can run CI workflows on your GitHub repository and push your code to a production environment or to GitHub Pages.
You will learn to write a YAML file, use actions/checkout@v3, run npm install, and send your site live from the main branch. Keep reading.
Key Takeaways
- You start by forking or creating a GitHub repo, cloning it locally, switching to main, copying your site files, running npm install, then committing (git add, git commit -m) and pushing. Finally, add SSH keys under Settings > Secrets.
- In .github/workflows, create a deploy.yml that triggers on push to main, pull_request, and workflow_dispatch. Define a job on ubuntu-latest that uses actions/checkout@v3 and actions/setup-node@v3 (node-version: 16).
- Store SSH_PRIVATE_KEY, SSH_USER, SSH_HOST, SSH_REPO_PATH, and GITHUB_TOKEN as repository Secrets or in Environments. Apply protection rules and require approvals for the production environment.
- Add steps for dependency install (npm install or bundle install) and build (npm run build). Deploy your output via scp or rsync using SSH keys, or push to the gh-pages branch with the GitHub Pages action and secrets.GITHUB_TOKEN.
- Use concurrency: group: production and cancel-in-progress: true to prevent overlapping runs. Monitor all workflow runs, inspect logs, and approve production jobs in the Actions tab.
How do I create a GitHub repository and upload my website code?
You need a repo before you run GitHub Actions. Use a fork or start fresh.
- Log into your GitHub account and click New repository in the top right. Choose a name that matches your site and hit Create repository.
- Visit the author’s sample code repository and click Fork. Pick your account. This creates a copy for your project.
- Open a terminal and run git clone with the repo URL. Switch to the main branch with git checkout main. Confirm actions/checkout@v3 can pull your code later.
- Copy your website files into the local folder. Run npm install if you use Node.js or a static site generator. Commit with git add, git commit -m, and git push.
- Go to Settings, select Actions, then click Secrets. Add SSH credentials under New repository secret. Paste your key and save.
- Use secrets.github_token or your SSH key in the workflow YAML. This lets GitHub Actions handle continuous integration and continuous delivery.
Setting up your workflow file in the. github/workflows directory
Your YAML file lives in .github/workflows, guiding each step like a recipe card for GitHub Actions. Add actions/checkout@v3, run the JS runtime setup, drop in secrets.github_token, and watch CI/CD deploy your site.
How do I create and configure the workflow file?
GitHub Actions runs tasks on each push. A yaml file in .github/workflows ties jobs together.
- Open GitHub and click the Actions tab. Kick the deployment tires with a new workflow.
- Add a yaml file named deploy.yml inside .github/workflows. Use the .yml extension.
- Set on: push event for the main branch. This yaml file triggers continuous deployment.
- Define a job runpool and select ubuntu-latest or a docker container. This job hosts your build.
- Insert actions/checkout@v3 to fetch your source code. It links to your main branch.
- Use actions/setup-node@v3 with node-version 16. Run npm install to load libraries.
- Store SSH_PRIVATE_KEY, SSH_USER, SSH_HOST, SSH_REPO_PATH as GitHub secrets. Call them secrets.github_token for CI security.
- Write steps to run npm run build with a static site generator. Deploy via SSH scp or rsync to the production environment.
How do I define the trigger event for my GitHub Actions workflow?
Open the workflow yaml file in .github/workflows to configure GitHub Actions. Specify trigger events under the on key. You can list push, pull_request, or workflow_dispatch. The push event targets the main branch by setting branches: [main].
A commit to the repo kicks off a continuous integration run.
Add workflow_dispatch to let you run the pipeline from the Actions interface. Pull requests can also start the automated pipeline on merge. Include actions/checkout to fetch your code.
A production environment can block runs on non main branches.
How do I configure deployment environment variables and secrets?
GitHub Actions stores env vars and secrets. You need tight control over deployment keys.
- Access the Actions tab in your repo. Pick Secrets and variables to open GitHub secrets.
- Click New repository secret. Add SSH credentials under a name like SSH_KEY.
- Navigate to Environments in the repo settings. Create a production environment then add each secret.
- Set deployment protection rules. Limit access to secrets for specified environments only.
- Add required reviewers to the environment. Require approval for jobs to proceed before secrets run.
- Reference secrets.github_token, SSH_KEY, and other env vars in your YAML file. Use them for authentication in continuous integration and continuous deployment workflows.
How do I check out repository code within a GitHub Actions workflow?
We fetch code with a checkout step. This brings your source to the runner.
- Add a checkout step in your yaml file under .github/workflows to start the process.
- Define uses: actions/checkout@v3 to clone the repository onto the virtual machine.
- Include with: fetch-depth: 0 to pull all commits, branches, and tags for full history.
- Bind GITHUB_TOKEN from secrets.github_token so private repos unlock without extra steps.
- Configure ssh-key from github secrets to enable secure server access or private module pull.
- Set path if you need a custom folder for your code instead of the default workspace.
- Run a cleanup step with a simple script to remove temp files after the build completes.
How do I install necessary dependencies for my website in the workflow?
You need to add dependency steps to your YAML file. These steps let GitHub Actions install packages before your build.
- Use actions/checkout@v3 to fetch code from your GitHub repository for continuous integration. This action pulls your source into the runner.
- Add actions/setup-node@v3 with node-version input to set up the Node.js runtime. This prepares npm install and other scripts.
- Run npm install to download modules listed in package.json from the npm registry. It loads packages for your static site generator.
- Invoke npm run build to create files via your chosen static site generator. Build output goes into the public or dist folder.
- Include bundle install if a Ruby gem manager handles your Jekyll or other generators. This step fetches gems defined in Gemfile.
- Place the value from secrets.github_token into your YAML file as a deployment token. GitHub Actions reads that token from your repository secrets.
How do I deploy my website to the specified environment using GitHub Actions?
This step moves your build to the live server. It makes sure your site serves real traffic.
- Define a deploy job and tag it with environment: production or staging to match your target VM.
- Add a concurrency block under the job in your GitHub workflows YAML file with group: production and cancel-in-progress: true to stop extra runs.
- Use the actions/checkout@v3 action to pull code from your main branch and set up source control for the deployment.
- Call actions/setup-node@v3 to install node.js then run npm install and npm run build to create your static site.
- Copy build files to your server with an scp command like scp -r ./public/ user@host:/var/www using SSH keys from GitHub secrets.
- Use continuous deployment to GitHub Pages by adding the GitHub Pages action or zip the output and push it to the gh-pages branch using secrets.GITHUB_TOKEN.
- Check the Actions tab to monitor workflow runs, inspect logs, and view your deployment history after each push.
Takeaways
You can push code updates and watch the site go live. A CI/CD workflow builds, checks and deploys your Jekyll site to an Ubuntu VM with SSH keys. GitHub Actions triggers on a push to main and runs npm install, npm run build and rsync.
It cuts manual steps and keeps your site fresh. You now own a smooth deploy flow that boosts your code quality and saves time.
