atmos aws cloudformation changeset create
Create a CloudFormation changeset for the component and leave it in place for
later manual review and execution — the explicit-control complement to
diff/plan's
implicit, preview-only changeset (which is also left in place, but framed as
a one-off preview rather than a named, reusable artifact).
Usage
atmos aws cloudformation changeset create <component> --stack <stack> [options]
atmos aws cloudformation changeset create vpc -s plat-ue2-dev
Create changesets for all or affected components in dependency order:
atmos aws cloudformation changeset create --all -s plat-ue2-dev
atmos aws cloudformation changeset create --affected --base origin/main
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)- Create changesets for all
aws/cloudformationcomponents in dependency order. --affected(optional)- Create changesets for affected
aws/cloudformationcomponents and their dependencies. --include-dependents(optional)- With
--affected, include dependentaws/cloudformationcomponents. --tags(optional)- Filter by tags (comma-separated, matches any):
--tags=production,tier-1. Composes with--all/--affectedto narrow the selected set further; cannot be combined with a single component argument. --labels(optional)- Filter by labels (comma-separated
key=valueorkey:valuepairs, matches all):--labels=cost-center=platform,compliance=sox. Composes with--all/--affected/--tags; cannot be combined with a single component argument.
Output
On success, the summary includes the changeset's ID and name, whether it was a
no-op (no changes to apply), and the predicted changes — the same diff summary
diff renders. Execute the named
changeset later with
changeset execute.
