atmos aws cloudformation changeset execute
Execute a previously-created, named changeset (ExecuteChangeSet) and stream
stack events until the operation reaches a terminal state — unlike
apply, which creates (or reuses)
and executes a changeset in one step, changeset execute acts on an
existing changeset by name, created earlier with
changeset create.
Usage
atmos aws cloudformation changeset execute <component> --stack <stack> --changeset-name <name> [options]
atmos aws cloudformation changeset execute vpc -s plat-ue2-dev --changeset-name vpc-2026-08-25
Skip the interactive confirmation prompt:
atmos aws cloudformation changeset execute vpc -s plat-ue2-dev --changeset-name vpc-2026-08-25 --auto-approve
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. --changeset-name(required)- Name of the changeset to execute.
--auto-approve(optional)- Skip the interactive confirmation prompt. Without it,
changeset executeprompts for confirmation on a TTY before executing the changeset. --all(optional)- Execute the named changeset for all
aws/cloudformationcomponents in dependency order. --affected(optional)- Execute the named changeset 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.
Behavior
If the stack ends in a failed status after executing the changeset (e.g.
UPDATE_ROLLBACK_COMPLETE), changeset execute exits non-zero.
