atmos aws cloudformation get template

Fetch the deployed stack's template (GetTemplate) and write it to stdout. By default this is the fully-processed template CloudFormation actually deployed — the same shape a diff against the local render should compare against — not the user-submitted source.

Experimental

atmos aws cloudformation get template --help

Usage

atmos aws cloudformation get template <component> --stack <stack> [options]

atmos aws cloudformation get template vpc -s plat-ue2-dev

Fetch the original, user-submitted template instead of the processed one:

atmos aws cloudformation get template vpc -s plat-ue2-dev --original

By default the template is re-serialized as pretty-printed YAML, because CloudFormation often stores the processed template as JSON. With --original, Atmos prints the body exactly as CloudFormation returned it, byte for byte, with comments, quoting, and key order intact, so you can diff it against your source file:

atmos aws cloudformation get template vpc -s plat-ue2-dev --original > deployed.yaml
diff template.yaml deployed.yaml

A stack that does not exist is an error that points at atmos aws cloudformation apply.

Flags

--stack, -s (required for a single component)

Atmos stack. Required when operating on a single component; optional (and used only to narrow the selected set) with --all/--affected.

--original (optional)

Fetch the user-submitted template instead of the processed one CloudFormation deployed, and print it exactly as returned, without re-serializing it.

--all (optional)

Process all aws/cloudformation components in dependency order.

--affected (optional)

Process affected aws/cloudformation components and their dependencies. Compares the working tree against a base: see --base and the Git flags below.

--include-dependents (optional)

With --affected, include dependent aws/cloudformation components.

--base (optional)

Git base ref or SHA to compare against for affected detection: --base=origin/main. A value that looks like a commit SHA is treated as --sha, anything else as --ref. Used with --affected.

--tags (optional)

Filter by tags (comma-separated, matches any): --tags=production,tier-1. Composes with --all/--affected to narrow the selected set further; cannot be combined with a single component argument.

--labels (optional)

Filter by labels (repeatable and/or comma-separated key=value or key:value pairs, matches all): --labels=cost-center=platform,compliance=sox. Composes with --all/--affected/--tags; cannot be combined with a single component argument.

--ci (optional)

Enable native CI integration (requires ci.enabled): writes the job summary and output variables for the operation. Also enabled by the CI and ATMOS_CI environment variables.

--ref (optional)

Git ref to compare against for affected detection. Used with --affected.

--sha (optional)

Git SHA to compare against for affected detection. Used with --affected.

--repo-path (optional)

Path to an already cloned target repository to use as the affected baseline. Used with --affected.

--clone-target-ref (optional)

Clone the target ref instead of checking it out in the current repository for affected detection. Used with --affected.

--ssh-key (optional)

Path to the SSH private key used to clone the target ref for affected detection. Used with --clone-target-ref.

--ssh-key-password (optional)

Password for the SSH private key used to clone the target ref for affected detection. Used with --clone-target-ref.

note

get template does not fire before/after hook events — only apply, diff, delete, drift detect, and drift describe do.
