# 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`](/cli/commands/aws/cloudformation/diff)/[`plan`](/cli/commands/aws/cloudformation/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).

> ⚠️ Experimental

## Usage

```shell
atmos aws cloudformation changeset create <component> --stack <stack> [options]
```

```shell
atmos aws cloudformation changeset create vpc -s plat-ue2-dev
```

Create changesets for all or affected components in dependency order:

```shell
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/cloudformation`
   components in dependency order.
- **`--affected` (optional)**
  Create changesets for affected 
  `aws/cloudformation`
   components and their dependencies.
- **`--include-dependents` (optional)**
  With 
  `--affected`
  , include dependent 
  `aws/cloudformation`
   components.
- **`--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 (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.

## 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`](/cli/commands/aws/cloudformation/diff) renders. Execute the named
changeset later with
[`changeset execute`](/cli/commands/aws/cloudformation/changeset/execute).

:::note
`changeset create` does not fire `before`/`after` hook events — only
[`apply`](/cli/commands/aws/cloudformation/apply),
[`diff`](/cli/commands/aws/cloudformation/diff), and
[`delete`](/cli/commands/aws/cloudformation/delete) do.
