Cross-region & cross-account AWS resources Terraform planning

Hey, it's been a while, right?

Lately, I'm leading some big changes in our infrastrure since I'm wrapping a Blue/Green deployment into another one. Uh?

Long story short: our product runs on AWS ECS Docker containers, and because we have one sub-domain per app instance, we use Apache wildcard sub-domains. Meaning a single container handles traffic from many clients/instances. We already have a Blue/Green deployment process in place but at the Docker container level, not at the client level. The idea is to entirely duplicate the whole stack (with all its flaws) and a sub-domain pointing to

At work, we previously used CoreOS to deploy a fleet of Dockerized apps but it was hard to maintain but more specifically, CoreOS is designed for distributed apps, which is not the case of this blog.

AWS ECS: seamlessly handle app versioning

Our latest project at work involved another Go API and in the effort of easing our debugging and issue tracking I'm used to inject the app version into the logs.

Preamble

Pre-2018, I hardcoded the version in an app constant which I would increment as part of my release process. It's easy, quick but the only issue is to not forget about it because you may lose versioning syncing over time.

Plus, considering this to be done before each new release, this adds
