= Creating an application from an image
|
|
|
|
You can deploy an application from an existing image. Images can come from image streams in the {product-title} server, images in a specific registry, or images in the local Docker server.
|
|
|
|
The `new-app` command attempts to determine the type of image specified in the arguments passed to it. However, you can explicitly tell `new-app` whether the image is a container image using the `--docker-image` argument or an image stream using the `-i|--image-stream` argument.
|
|
|
|
[NOTE]
|
|
====
|
|
If you specify an image from your local Docker repository, you must ensure that the same image is available to the {product-title} cluster nodes.
