Azure Private DNS destroys the VM #27364

Closed khandujaniket closed 3 years ago

khandujaniket commented 3 years ago

I have two azure TF modules

  1. Linux Virtual Machine
  2. Private DNS

I am using Terragrunt as a wrapper on TF. Private DNS is dependent on Virtual Machine and this dependency is maintained in Terragrunt.

Terraform Version

0.14.3

When I execute the Terragrunt apply-all following happens

  1. VM is created and output is presented
  2. Then Private DNS starts provisioning and then it starts destroying the VM. I am unable to pin point the issue.

I have a single state file for both modules.

Hello

We use GitHub issues for tracking bugs and enhancements, rather than for questions. While we can sometimes help with certain simple problems here, it's better to use the community forum where there are more people ready to help. The GitHub issues here are monitored only by our few core maintainers.

Based on the information you've provided, I don't immediately see evidence of a bug in Terraform core, though I also don't entirely understand what is causing this. It's possible that there's a defect, but there's not quite enough evidence here for me to treat it as one. There are two possible next steps for you:

  1. I think your best bet is to seek support on the community forum.

  2. Alternatively, if you can provide a simplified, full example here of a terraform config that I can run to reproduce an issue in which explicit output dependencies are ignored, I may be able to confirm that this is a defect in core or the AWS provider and get it on our backlog. We don't maintain Terragrunt, so if your reproduction case requires Terragrunt, you should report it to that project. If you are able to craft a simple reproduction that shows a bug in Terraform Core without Terragrunt, I'm happy to help investigate.

I'm going to close this for now, because I think the community forum is the right approach. Feel free to leave a note or contact me at ddreier@hashicorp.com to re-open this if you'd rather work up a repro case here.

I'm going to lock this issue because it has been closed for 30 days ⏳. This helps our maintainers find and focus on the active issues.

If you have found a problem that seems similar to this, please open a new issue and complete the issue template so we can capture all the details necessary to investigate further.
