atmos aws cloudformation

Deploy, inspect, and delete native aws/cloudformation stacks directly through the AWS SDK for Go v2 — the same stack-based workflow you use for Terraform, Helm, and Kubernetes components, with no aws CLI or cfn/sam/Rain binary dependency. Alias: atmos aws cfn.

Experimental

Configure CloudFormation Components

Set the default component location in atmos.yaml, then describe each stack's template, parameters, capabilities, and delivery behavior with template, stack_name, parameters, capabilities, tags, stack_policy, and more.

Stack Configuration

atmos aws cloudformation --help

Usage

atmos aws cloudformation render <component> --stack <stack>
atmos aws cloudformation diff <component> --stack <stack>
atmos aws cloudformation plan <component> --stack <stack>
atmos aws cloudformation apply <component> --stack <stack>
atmos aws cloudformation deploy <component> --stack <stack>
atmos aws cloudformation delete <component> --stack <stack>
atmos aws cloudformation validate <component> --stack <stack>
atmos aws cloudformation output <component> --stack <stack>

atmos aws cloudformation apply --all --stack <stack>
atmos aws cloudformation apply --affected --base origin/main

atmos aws cloudformation apply --affected --tags production
atmos aws cloudformation apply --all --labels cost-center=platform

The cfn alias works everywhere cloudformation does:

atmos aws cfn apply vpc -s plat-ue2-dev
