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.

$ oc new-app mysql

$ oc new-app myregistry:5000/example/myimage
