expose git commit revision id as environmental variable to hook steps

[woodhull]

Our CI systems precompiles some artifacts and stores them in S3 with the git revision as the unique identifier.

We'd like the scripts that run on deploy to download the correct version based on the deployed git commit id. Right now it's awkward, since we need to query for the deployment ID and then get the git commit id from there.

Seems like a reasonable feature request. Thanks.

Seconding this feature. Some usage details so you understand our use case:

We don't use S3, but instead deploy via CodeDeploy directly from GitHub (GUI: "My application is stored in GitHub" checkbox). We really need a way within an AfterInstall hooks script to be able to get the git commit SHA (GUI: "Commit ID") so it can be put into a file on the server. This would save me having to tell our developers "Just use the GUI" to find out what code is actively on the box (and yes I'm well aware the agent has this information deep within /opt/codedeploy-agent). An environment variable would be absolutely perfect.

I have the exact same issue and workaround as woodhull. Querying the deployment ID to get the commit id. +1 for this feature request!
