Terraform: EIP reallocation failure

[cstruct]

Hi,

Since the v0.6.15 release terraform cannot reassociate elastic IPs.

Terraform Version

Fails on Terraform v0.6.15
Succeeds on Terraform v0.6.14

Affected Resource(s)

• aws_eip
  

  Terraform Configuration Files

Changing config from:

resource "aws_eip" "default" {
  vpc = true
  instance = "${aws_instance.instance_a.id}"
}

to:

resource "aws_eip" "default" {
  vpc = true
  instance = "${aws_instance.instance_b.id}"
}

Debug Output

TRACE log

Expected Behavior

The EIP should be reassociated with the new instance

Actual Behavior

Terraform fails with:

aws_eip.default: Failure associating EIP: InvalidParameterValue: 10.x.x.x is not mapped to the interface eni-xxxxxxxx

Steps to Reproduce

1. set existing aws_eip.instance to a new value
2. terraform apply

Ran in to this as well.

@cstruct Thanks for taking the time to write up a thorough bug report. I wasn't certain if I was doing something stupid with AWS or if this was an issue...

Hey @cstruct thanks for opening this!

6521 should fix this. Note that if you're using private_ip in your EIP resource, you'll need to use the new associate_with_private_ip attribute that's added in that pull request

Thank you @catsby
