atmos aws cloudformation render

Render the component's local template — resolved from template: and, when source: is set, JIT-provisioned first — without calling any AWS API. render does not authenticate, so it works offline and without AWS credentials.

Experimental

atmos aws cloudformation render --help

Usage

atmos aws cloudformation render <component> --stack <stack> [options]

atmos aws cloudformation render vpc -s plat-ue2-dev

Render all or affected components in dependency order:

atmos aws cloudformation render --all -s plat-ue2-dev
atmos aws cloudformation render --affected --base origin/main

Render components filtered by tags or labels (composes with --all/--affected to narrow the selected set further):

atmos aws cloudformation render --all --tags production,tier-1
atmos aws cloudformation render --affected --labels cost-center=platform

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.

--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

render skips authentication and never calls the CloudFormation API. To preview the changes an apply would actually make against the deployed stack, use diff (alias plan).
