Question
How do you make sure that your Azure credentials are not stored in plain text in your repository?
A. Use GitHub Secrets to securely store your Azure credentials.
B. Use your GitHub token to authenticate into Azure
C. Put your credentials directly in your workflow file.
Answer
A. Use GitHub Secrets to securely store your Azure credentials.
Explanation
Storing your credentials in GitHub secrets allows you to use the credential in a workflow without exposing the credential in plain text.
To ensure that your Azure credentials are not stored in plain text in your repository when using GitHub Actions, the best practice is to use GitHub Secrets to securely store your sensitive information.
GitHub Secrets provide a secure way to store sensitive data, such as Azure credentials, within your GitHub repository. These secrets are encrypted and can only be accessed by GitHub Actions during the execution of your workflows. By using GitHub Secrets, you can avoid exposing your Azure credentials in plain text in your workflow files or anywhere else in your repository.
Here’s how you can use GitHub Secrets to store your Azure credentials securely:
- Go to your GitHub repository’s settings.
- Navigate to the “Secrets” section.
- Click on “New repository secret” to create a new secret.
- Provide a name for your secret, such as “AZURE_CREDENTIALS”.
- Enter your Azure credentials (e.g., service principal ID and secret) as the value for the secret.
- Save the secret.
Once you have created the GitHub Secret, you can reference it in your workflow file using the syntax `${{ secrets.AZURE_CREDENTIALS }}`. GitHub Actions will automatically substitute the actual value of the secret during the workflow execution, ensuring that your Azure credentials remain secure and are not exposed in plain text.
It’s important to note that using your GitHub token to authenticate into Azure (option B) is not recommended for accessing Azure resources. The GitHub token is primarily used for interacting with the GitHub API and does not provide the necessary permissions or security for Azure authentication.
Putting your Azure credentials directly in your workflow file (option C) is a highly insecure practice and should be avoided at all costs. Storing credentials in plain text in your repository poses a significant security risk, as anyone with access to your repository can view and potentially misuse your Azure credentials.
In summary, the best and most secure way to store your Azure credentials in GitHub Actions workflows is by using GitHub Secrets. This ensures that your sensitive information remains encrypted and protected, while still allowing your workflows to authenticate and access Azure resources as needed.
