Set up version control and roll back to previous configurations
Integrate Terraform and Git to get robust versioning and rollback capabilities for your CDN configurations. This setup ensures better stability of your infrastructure as you can quickly revert any changes with minimal downtime and fewer potential issues.Follow the best practices outlined below to efficiently manage and secure your infrastructure changes.
Use a consistent branching strategy. Even if you are working primarily on the main branch, consider creating branches for specific changes. Merge your changes into the main branch only after thorough testing.
Write meaningful commit messages. This ensures that the history of changes is easy to understand, specifically for contributors who don’t have enough context about the updates.
Regularly tag releases or significant changes. If there are any issues, it’ll be easier to revert to a stable state.
Test rollback procedures. This practice minimizes risks when an actual rollback is needed since you know that everything works as expected.
Secure sensitive data. Use environment variables or secret management services for sensitive data like API tokens. Ensure that these values are not committed to version control.
Sometimes, changes made to your configurations may result in unexpected behavior. Having a rollback strategy allows you to quickly revert to the last known good configuration, minimizing downtime and ensuring stability.
Apply the configuration from the checked-out version: terraform apply.That’s it! You’ve successfully rolled back to the needed version and can continue your work.
