This is a 🐞 bug fix.

Summary

Fix terraspace all down.

The #196 change in v1.1.0 means only required stacks are built. It works for terraspace all up, and then terraspace all down would work as long as the .terraspace-cache folder still exist.

However, on a clean machine without .terraspace-cache, terraspace all down wouldn't work because the dependent stacks were not built and available for terraform state pull to work.

This fixes the issue by building the dependent stacks. Additionally, added a codebuild project with an acceptance test for terraspace all has been added. See: #216

Context

• terraspace all: build modules in batches and only each specific stack #196
• build required dependent stacks as part of terraspace up #199
• https://community.boltops.com/t/terraspace-all-down-not-building-dependent-stacks/848/4

How to Test

git clone https://github.com/boltops-tools/terraspace-graph-demo
cd terraspace-graph-demo
terraspace all up -y
terraspace clean all -y
terraspace all down -y # should work
