How do I implement blue/green deployments for Commit message conventions?

Blue/Green deployments are a software deployment strategy that reduces downtime and risk by running two identical production environments, called Blue and Green. This method allows you to switch traffic between the two environments while ensuring that one is always live. The idea is to deploy new changes to the ‘Green’ environment while the ‘Blue’ is still serving the production traffic. Once the new version is ready and tested, you switch the traffic over to ‘Green’. If something goes wrong, you can quickly roll back to ‘Blue’.

When implementing blue/green deployments, using commit message conventions is crucial. It allows you to track changes efficiently and aids in identifying which commits correspond to deployments. Commit messages should be structured in a way that indicates the environment, changes made, and notes for future reference.

A recommended commit message structure might be:

• Type: The type of change (feat, fix, chore)
• Environment: Specify 'blue' or 'green'
• Scope: The area of the codebase the change affects (if applicable)
• Subject: A short description of the change

For example, a commit message could look like:

In this example, 'feat' indicates a new feature, 'green' specifies which environment is being updated, and the rest provides context about the change.
