Rollback deploys

[REBELinBLUE]

Implement the deployment rollback as the button is there but doesn't do anything

Any suggestions about the rollback? It's seem to that just rollback the code is secure. Database or some user upload file should not be rollback.

So may be just create a soft link file back to the specific revision is enough.

Yeah essentially all I was going to do is repoint the symlink to the release. As you said there is no easy way to automatically rollback a deployment completely due to DB migrations etc

[REBELinBLUE]

I think rather than simply re-creating a symlink it will need to essentially do a redeploy of a specific commit, which should be possible once I implement #49

[iflamed]

I still think redeploy is not a secure way to rollback. It will run some command of the deploy, and do some job we don't know. Maybe there is no redeploy, it's just deploy a specific commit.

@REBELinBLUE May I was wrong. I see the dploy.io do rollback by create a new deployment.

Being addressed as part of #129
