Issue

This is to note that issue #9209 is closed but not solved; creating a aws_dx_gateway_association_proposal and accepting it will still, after a few days, try to recreate the aws_dx_gateway_association_proposal. See #9209 for all information.

Thanks for reporting this @toelke! @ewbankkit, do you have any feedback on what could be happening here?

[ewbankkit]

@toelke Can you attach the output of a terraform plan or terraform apply that shows the proposal being recreated?
This will help greatly with our troubleshooting.
Thanks.

When applying this it will work but break the association for a few minutes. In three days or so it will again want to re-create the proposal.

The original poster in #9209 has this quote from AWS: "Once the proposal is accepted, it will disappear after some time. There is no defined time duration as to how long the proposal is available after acceptance". See especially the comment #9209 (comment)

@toelke You could try adding

  lifecycle {
    ignore_changes = [
      proposal_id,
    ]
  }

to the aws_dx_gateway_association resource.

[toelke]

Yes, but the proposal will still be re-created, breaking the connection.

[ewbankkit]

Aah, so it's the creation of the new proposal that causes the association to break (and thus the network outage) rather than the change of the proposal ID in the aws_dx_gateway_association (because from the code, updating proposal_id doesn't actually do anything)?

[toelke]

I can try to check that.

In any case terraform would recreate the proposal every few days which will show up as configuration drift. Even without outage that's not ideal.

[toelke]

I tested re-creating the proposal and not changing the aws_dx_gateway_association (by using ignore_changes) and the connection stays up even if I accept or reject the new proposal in the web-console.

So using ignore_changes is indeed a solution for not breaking the connection.

I would still prefer not to have config drift, though.
