Fixing go mod tidy Issues with Internal Repositories in GitHub Actions

If you've ever tried to run the command go mod tidy using an internal GitHub repository via SSH and encountered permission errors such as "Permission denied (publickey)", you're not alone. This common issue often arises in GitHub Actions, where SSH keys must be handled carefully to ensure seamless access to private repositories. Let's delve into the problem and explore a reliable solution.

The Problem: Understanding the SSH Authentication Failure

When you execute go mod tidy, it attempts to download dependencies from your internal repositories. The error message that you might see is as follows:

What This Means

This message indicates that the SSH authentication for accessing your internal repository failed. Although your GitHub Actions log might confirm that the SSH key has been added properly, each step in GitHub Actions runs in a separate process. Therefore, any environment variables or agent configurations established in one step do not carry over to the next step.

A Step-by-Step Solution: Ensuring Proper SSH Authentication

To fix the go mod tidy issue and ensure successful access to your internal repositories, you need to re-establish the SSH authentication in the Install dependencies step of your GitHub Actions. Here’s a structured guide on how to do that.

1. Set Up Your GitHub Actions Steps

Below is an adjusted version of your GitHub Actions workflow that includes the necessary SSH agent setup for the Install dependencies step:

2. Key Considerations

Separate Processes: Remember that each step runs in its own process; therefore, authentication setups must be repeated as needed.

SSH Agent Setup: By calling eval "$(ssh-agent -s)" and ssh-add key.pem again in the Install dependencies step, you ensure that the GitHub Actions environment is correctly configured to use the SSH key.

3. Final Checks

Repository Access: Ensure that the private key used has the necessary permissions to access the internal repository.

Existing Repositories: Confirm that the repository exists and the provided GitHub actions secrets are correctly set.

Conclusion

By adjusting your GitHub Actions workflow to re-establish the SSH agent in each relevant step, you can effectively resolve the go mod tidy issues when working with internal repositories. This solution streamlines the process and helps maintain a smooth development workflow with Go and GitHub Actions.

If you follow these steps correctly, you should find that your go mod tidy command runs successfully without any permission issues. Happy coding!
