atmos aws cloudformation logs
Show the combined CloudFormation event log across a stack and every nested stack beneath it (up to 10 levels deep), merged into a single chronological timeline — instead of having to check each nested stack's events separately.
Usage
atmos aws cloudformation logs <component> --stack <stack> [options]
atmos aws cloudformation logs vpc -s plat-ue2-dev
Render a per-resource timeline instead of a flat chronological list:
atmos aws cloudformation logs vpc -s plat-ue2-dev --chart
Show logs for all or affected components in dependency order:
atmos aws cloudformation logs --all -s plat-ue2-dev
atmos aws cloudformation logs --affected --base origin/main
Flags
--stack,-s(required)- Atmos stack.
--chart(optional)- Render a per-resource timeline (one line per logical resource ID, showing its status transitions in order) instead of a flat chronological event list.
--all(optional)- Show logs for all
aws/cloudformationcomponents in dependency order. --affected(optional)- Show logs 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
By default, every event from the stack and its nested stacks is printed in
timestamp order, the same as a single stack's event stream. With --chart,
events are grouped by logical resource ID instead, one line per resource
showing its status transitions in order:
NatGateway CREATE_IN_PROGRESS -> CREATE_COMPLETE
SubnetsStack CREATE_IN_PROGRESS -> CREATE_COMPLETE
