Also include as much context as you can about your config, state, and the steps you performed to trigger this error.


Terraform does not automatically rollback in the face of errors.
Instead, your Terraform state file has been partially updated with
any resources that successfully completed. Please address the error
above and apply again to incrementally change your infrastructure.
make: *** [apply] Error 1

Steps to Reproduce

All you need is terraform apply.

Important Factoids

It appears to be the module above, but I have a bunch of other stuff running in this.

After this, if I run apply again it seems to converge (though there may still be something broken that I haven't noticed).

References

appears to be same as these, but I didn't find that until I'd written this whole thing up. Feel free to move it–

• Autoscaling group diffs didn't match during apply (error applying plan) #15978

[apparentlymart]

Hi @ryanking! Sorry for this strange behavior.

This seems to be the same as #15810, so I'm going to close this out just to consolidate over there.

[ghost]

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.
