Introduction

If you're new to GitLab Pipelines, you may encounter a frustrating issue: the message "remote: HTTP Basic: Access denied" during the execution of your pipeline. This can happen when trying to pull a private repository. Understanding the cause of this problem and how to fix it is key to getting your CI/CD flow started smoothly. In this post, I’ll walk you through the steps to resolve this issue based on common scenarios and provide a clear solution to help your GitLab Runner access your repositories successfully.

Understanding the Error

When you try to execute a pipeline, GitLab Runner attempts to clone your repository. If the repository is private and the runner lacks the necessary permissions, you will see an error message like this:

This error typically points to authentication issues, meaning that the runner cannot authenticate with the GitLab server when trying to access the private repository.



Common Scenarios and Solutions

1. GitLab Runner Configuration

Upon setting up your GitLab Runner with Docker, you may have overlooked some configurations critical for authentication.

Steps to Configure the Runner:

Edit the config.toml file of the GitLab Runner.

Add or modify the following lines to ensure proper URLs are set:

By specifying the clone_url, you can bypass certain authentication issues that arise from using the incorrect endpoint.

Key Points:

Ensure your URL matches the access point of your GitLab instance.

Verify that you are using HTTPS, which provides an encrypted connection.

Remember that changes to the .toml file may require a restart of the GitLab Runner for them to take effect.

2. Check Your Permissions

If you're still encountering problems after configuring the runner, ensure that the runner is assigned to the correct project with the necessary permissions:

Make sure the runner has at least Developer access to the private repository.

If using a shared runner, confirm that it is configured correctly within GitLab and associated with the project.

3. Proxy or Network Issues

In some cases, GitLab may be hosted behind a proxy. This can complicate matters, as the runner needs to communicate properly through that proxy.

Suggested Actions:

Verify that your GitLab instance and runner are not blocked by firewall rules.

Test connectivity with and without the proxy settings to identify possible restrictions.

4. Testing with Public Repositories

You mentioned testing your pipeline with a public repository, which succeeded. This indicates that the issue primarily lies with the authentication settings for private repositories. It’s crucial to confirm:

Your GitLab authentication tokens or CI/CD variables are correctly set up.

You can access the repository manually using the same authentication method.



Conclusion

By following the outlined steps, you can effectively resolve the "HTTP Basic: Access denied" error in your GitLab Pipelines. Managing permissions and configuring the GitLab Runner properly are keys to ensuring that your CI/CD process runs uninterrupted.

If you continue facing issues, consider reaching out to the community forums or checking GitLab’s documentation for any additional settings specific to your version or environment. Happy coding!
