Terraform Diagnostics Display

As part of the upgrading from v3 to v4 of the Terraform AWS Provider, I needed to see all the places where I needed to do some work. The standard ouput from Terraform doesn't show all the places where work is required. But, luckily, using the -json option, you get access to all of the information.

The following shell script (written and tested in bash, but should be OK as really, it's only terraform, jq, column, and | that's being used) will output a nicely formatted table showing you the

My use case is to get the current desired capacity of an autoscaling group so that I can use that in the replacement autoscaling group. I've seen a Cloudformation solution, but that required more understanding than I have at the time.

Initially, I had thought that just returning the JSON from awscli would have been enough, but unfortunately, the result for the data_source.external.result is a list of strings. No numbers, arrays, maps, lists.

So inspired by a comment made by Marin Salinas, I found that Terraform can access local files!

In addition, I am using an assumed role to do the work.

ProMiReD

We needed a way to describe our pipeline deployment approach. How and when are things released. In what order do we modify the code and the database when it is not possible to do them all instantly.

And so we came up with this silly acronym. We know there are probably better approaches, but this has worked very well for us. To the point that our continuous integration and deployment pipelines can run all of these unattended, allowing our developers to develop and our reviewers to review and the poor release monkey can retire from running all those releases by hand.

Pro - Protect migrations

As migrations are developed and versioned using the current timestamp, and prior to Phinx 0.8, we needed to make sure that
