Browse Source 
Application cloning can be used to setup review applications based on an existing application. This is useful in CI/CD pipelines where a developer may wish to verify code in a custom environment without overwriting a shared staging environment.

This will copy all of your app's contents into a new app directory with the name of your choice, delete your old app, then rebuild the new version of the app and deploy it. All of your config variables, including database urls, will be preserved.
### Cloning an existing app
> New as of 0.8.1
You can clone an existing app using the `apps:clone` command. Note that the application *must* have been deployed at least once, or the rename will not complete successfully:
```shell
dokku apps:clone node-js-app io-js-app
```
```

This will copy all of your app's contents into a new app directory with the name of your choice and then rebuild the new version of the app and deploy it. All of your config variables, including database urls, will be preserved.
By default, Dokku will deploy this new application, though you can skip the deploy by using the `--skip-deploy` flag:
```shell
dokku apps:clone --skip-deploy node-js-app io-js-app
```
