Terraspace Demo: Dependency Graphs

Terraspace All Demo Video:

This project demonstrates how Terraspace is able to build the dependency graph and deploy multiple stacks at once. It creates a bunch of random_pet resources with dependencies on each other.

Setup

git clone https://github.com/boltops-tools/terraspace-graph-demo
cd terraspace-graph-demo
bundle

Graphs

To draw the full dependency graph defined by this project's resources:

terraspace all graph

Produces this:

Note: a3 is a stack/node is not parent and has no children.

To draw a targeted subgraphs:

terraspace all graph a2 b2

Produces this:

The green nodes are the targeted stacks.

Deploy

To deploy all the stacks with their resources:

terraspace all up

Terraspace provides a preview before deploying:

$ terraspace all up
Will run:
   terraspace up a3 # batch 1
   terraspace up c1 # batch 1
   terraspace up c3 # batch 1
   terraspace up e1 # batch 1
   terraspace up b1 # batch 2
   terraspace up b3 # batch 2
   terraspace up d1 # batch 2
   terraspace up a2 # batch 3
   terraspace up c2 # batch 3
   terraspace up b2 # batch 4
   terraspace up a1 # batch 5
Are you sure? (y/N)

To deploy subgraphs, specify the stacks:

$ terraspace all up a2 b2
Will run:
   terraspace up c1 # batch 1
   terraspace up c3 # batch 1
   terraspace up e1 # batch 1
   terraspace up b3 # batch 2
   terraspace up d1 # batch 2
   terraspace up a2 # batch 3
   terraspace up c2 # batch 3
   terraspace up b2 # batch 4
