# 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`](/cli/commands/aws/cloudformation/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`](/cli/commands/aws/cloudformation/changeset/create).

> ⚠️ Experimental

## Usage

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

```shell
atmos aws cloudformation changeset execute vpc -s plat-ue2-dev --changeset-name vpc-2026-08-25
```

Skip the interactive confirmation prompt:

```shell
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 execute`
   prompts for confirmation on a TTY before executing the changeset.
- **`--all` (optional)**
  Execute the named changeset for all 
  `aws/cloudformation`
   components in dependency order.
- **`--affected` (optional)**
  Execute the named changeset 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.

## Behavior

If the stack ends in a failed status after executing the changeset (e.g.
`UPDATE_ROLLBACK_COMPLETE`), `changeset execute` exits non-zero.

:::note
`changeset execute` 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.
