Looking for help to detect the drift in Terraform

[rushi47]

Hello 👋

I hope you are doing well

We are facing this issue, where lot of times PR is merged without running atlantis apply. We do with branch protection rules, but there are times, when things end up in main branch which are not applied. And there is drift.

By any chance is there any pattern, which everyone follows for this ? Or has anyone dealt with such issue and have solution, where maybe atlantis runs periodically to check drift. Something on the same terms.

Looking forward for thoughts :)

Thank you

people try to implement drift detection see : #3245

the closest one is a github action made by cresta that I did tried and worked so it is possible to do it that way.

ideally we will built this in into atlantis.( we need help)

Thanks @jamengual for the quick response. Will look at cresta. And will also check if we can contribute to this.

we created a homegrown solution that is basically a cron job that generates plans for each terragrunt deploy and looks at the changes and alerts in slack under certain conditions (ie: plan failure, resource destroy). It's a custom thing but it is doable. am eager to see how #3245 turns out
