[Practice Exercise](#practice-exercise) **Introduction** In this topic, you will learn how to create a Git repository and integrate it with a Continuous Integration (CI) tool of your choice. This hands-on lab will guide you through the process of creating a Git repository on GitHub or GitLab and linking it to a CI tool such as GitHub Actions, Jenkins, or CircleCI. **Step 1: Creating a Git repository** Before you can create a Git repository, make sure you have Git installed on your local machine. You can download and install Git from the official Git website: [https://git-scm.com/downloads](https://git-scm.com/downloads). To create a new Git repository, open your terminal or command prompt and navigate to the directory where you want to create your repository. Run the following command: ``` git init ``` This will create a new .git directory in your current directory. **Step 2: Creating a new repository on GitHub** To create a new repository on GitHub, follow these steps: 1. Log in to your GitHub account. 2. Click on the "+" button in the top-right corner of the page. 3. Select "New repository" from the dropdown menu. 4. Enter a name for your repository and a description (optional). 5. Choose a public or private repository, depending on your needs. 6. Add a `.gitignore` file to your repository (optional). 7. Click on the "Create repository" button. For more information on creating a new repository on GitHub, refer to the GitHub documentation: [https://docs.github.com/en/get-started/quickstart/create-a-repo](https://docs.github.com/en/get-started/quickstart/create-a-repo). **Step 3: Creating a new repository on GitLab** To create a new repository on GitLab, follow these steps: 1. Log in to your GitLab account. 2. Click on the "+" button in the top-right corner of the page. 3. Select "New project" from the dropdown menu. 4. Enter a name for your project and a description (optional). 5. Choose a public or private project, depending on your needs. 6. Add a `.gitignore` file to your project (optional). 7. Click on the "Create project" button. For more information on creating a new project on GitLab, refer to the GitLab documentation: [https://docs.gitlab.com/ee/gitlab-basics/create-project.html](https://docs.gitlab.com/ee/gitlab-basics/create-project.html). **Step 4: Initializing the local repository and linking it to the remote repository** To link your local repository to the remote repository you created on GitHub or GitLab, follow these steps: 1. Navigate to your local repository directory. 2. Run the following command to link your local repository to the remote repository: ``` git remote add origin <remote-repository-url> ``` Replace `<remote-repository-url>` with the URL of your GitHub or GitLab repository. For example, if your GitHub repository URL is `https://github.com/username/repository-name`, your command would look like this: ``` git remote add origin https://github.com/username/repository-name.git ``` 3. Run the following command to verify that the remote repository is linked: ``` git remote -v ``` This should display the URL of your remote repository. **Step 5: Choosing a CI tool and creating a new project** Choose a CI tool that integrates with your Git provider. For this lab, we will use GitHub Actions. To create a new project on GitHub Actions, follow these steps: 1. Log in to your GitHub account. 2. Navigate to your repository. 3. Click on the "Actions" tab. 4. Click on the "New workflow" button. 5. Choose a workflow template (optional). 6. Name your workflow and click on the "Create workflow file" button. **Step 6: Integrating the Git repository with the CI tool** To integrate your Git repository with GitHub Actions, you need to create a new workflow file in your repository. GitHub Actions provides pre-built templates for various programming languages and frameworks. 1. Create a new file in the `.github/workflows` directory of your repository. 2. Name your workflow file (e.g., `ci.yml`). 3. Paste the following YAML code into your workflow file: ```yaml name: CI on: [push] jobs: build: runs-on: ubuntu-latest steps: - name: Checkout code uses: actions/checkout@v2 - name: Install dependencies run: | npm install - name: Run tests run: | npm test ``` This is a basic example of a CI workflow that checks out your code, installs dependencies, and runs tests. **Conclusion** In this lab, you learned how to create a Git repository and integrate it with a CI tool. You created a new repository on GitHub or GitLab, initialized a local repository, and linked it to the remote repository. You then chose a CI tool (GitHub Actions) and created a new project. Finally, you integrated your Git repository with GitHub Actions by creating a new workflow file. **Practice Exercise** Try the following exercises to reinforce your understanding of this topic: * Create a new repository on GitHub or GitLab and link it to a CI tool of your choice. * Modify the workflow file to include additional steps, such as building and deploying your application. * Explore other CI tools and compare their features with GitHub Actions. **Leave a comment or ask for help** If you have any questions or need help with this lab, feel free to leave a comment below.
