Rollback integration with aws code pipeline which is deploying a React app on S3

Question

I have a code pipeline in AWS which performers CI/CD for my react app and deploy it into the s3 bucket.

Now I am curious how can I achieve a rollback in this flow.

my current code pipeline flow is:

git bucket(repo) - > Code build(to build the app into static hosting) - > code deploy action(with action provider s3).

In case anything goes wrong, how can I achieve a rollback into this CI/CD pipeline?

Can you clarify your setup? CodeDeploy can't deploy to S3, only to EC2/ECS and Lambda. — Marcin, Oct 05 '20 at 07:41
My action is "deploy" which deploys on S3, not the code deploy application. — sumanth shetty, Oct 05 '20 at 07:47

CodePipeline (CP) does not have build-in mechanism for rollbacks. Thus in your case I see three options:

if the target S3 bucket is versioned, you can roll back "manually" by deleting latest version of each object. This way you will effectively move back to a previous deployed version of your application.
You have to roll back on your bitbucket in a same way you would reverse last PR or commit. The change in bitbucket should trigger your CP to do new deployment, but of old version from the git repository.
The other option, could involve your CodeBuild to do a backup of your currently deployed files in the bucket while building new version of the app. This way each run of CP would also create a backup of an existing version to other bucket. Then the roll-back would be as simple as just copying files from one bucket to the other.
