Cheat Sheet

The information in this section is a copy of the preflight requirements and common command-line arguments from Terramate (https://github.com/terramate-io/terramate).

Terramate enables scalable automation for Terraform by providing a robust framework for managing multiple stacks, generating code, and executing targeted workflows.

1. Create a New Project

git init -b main terramate-quickstart
cd terramate-quickstart
git commit --allow-empty -m "Initial empty commit"

2. Create a Stack

terramate create \
  --name "StackName" \
  --description "Description of the stack" \
  stacks/stackname

git add stacks/stackname/stack.tm.hcl
git commit -m "Create a stack"

3. List Stacks

terramate list

4. Detect Changes

terramate list --changed

5. Generate Code

Create a .tm.hcl file for code generation:

cat <<EOF >stacks/backend.tm.hcl
generate_hcl "backend.tf" {
  content {
    terraform {
      backend "local" {}
    }
  }
}
EOF

Run the generation command:
```
terramate generate
```

6. Run Terraform Commands

Initialize stacks:
```
terramate run terraform init
```
Plan changes:
```
terramate run terraform plan
```

Apply changes:

terramate run terraform apply -auto-approve

Run commands only on changed stacks:

terramate run --changed terraform init
terramate run --changed terraform plan
terramate run --changed terraform apply -auto-approve
