atmos aws cloudformation plan --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 / --affected / --include-dependents (optional)

Process multiple aws/cloudformation components in dependency order. See diff.

--tags / --labels (optional)

Filter by tags (comma-separated, matches any) or labels (comma-separated key=value or key:value pairs, matches all): --tags=production,tier-1, --labels=cost-center=platform. Compose with --all/--affected to narrow the selected set further; cannot be combined with a single component argument.
