Terraspace also allows you to deploy all stacks with a single command:

terraspace all up

Terraspace calculates the dependency graph and ensures they are deployed in the correct order. Here’s a dependency graph example:

Terraspace will parallelize the batches as much as possible:

$ terraspace all up
Building one stack to build all stacks
Building .terraspace-cache/us-west-2/dev/stacks/c2
Downloading tfstate files for dependencies defined in tfvars...
Built in .terraspace-cache/us-west-2/dev/stacks/c2
Will run:
   terraspace up b2 # batch 1
   terraspace up c1 # batch 1
   terraspace up c3 # batch 1
   terraspace up d1 # batch 1
   terraspace up b1 # batch 2
   terraspace up c2 # batch 2
   terraspace up b3 # batch 3
   terraspace up a1 # batch 4
Are you sure? (y/N)

Once you confirm, Terraspace deploys the batches in parallel. Essentially, terraspace handles the orchestration.

Batch Run 2:

Terraspace also provides a reduced-noise summary of the runs. The full logs are also written for further inspection and debugging.

Targetting Subgraphs

You can also deploy specific parts of your infrastructure by specifying the stack names. Example:

Terraspace only deploys the subgraph:

$ terraspace all up b3
Will run:
   terraspace up c3 # batch 1
   terraspace up d1 # batch 1
   terraspace up c2 # batch 2
   terraspace up b3 # batch 3
Are you sure? (y/N)

You can also specify multiple stacks and subgraphs:

Here’s what that looks like:

$ terraspace all up b1 b3
Will run:
   terraspace up c1 # batch 1
   terraspace up c3 # batch 1
   terraspace up d1 # batch 1
   terraspace up b1 # batch 2
   terraspace up c2 # batch 2
   terraspace up b3 # batch 3
