Stacks / Deployments #2199
Description
A way to capture relationships across multiple Units - same purpose as Stacks in Terraform or Terragrunt
Motivation
It is considered best practice to split infrastructure into small state files, thus reducing blast radius. But then some of them clearly belong together - for example staging and production envoronment often have nearly identical topologies; same for regions. See Terraform Stacks and Terragrunt Stacks.
Design considerations
- Do we need 2 dimensions (components / deployments like in HCP Stacks) or just one is sufficient?
- Do we define Stacks via OpenTaco provider or standalone HCL / yml / some other config format?
