Publishing an Image

Whichever Registry you choose, publishing an image is a three-step process:

1. Build your image (docker build) with the appropriate prefix name or tag (docker tag) an existing one appropriately.

2. Log into the Registry (docker login).

3. Push the image into the Registry (docker push).

There are slight variations according to which Registry you use which we’ll see in the following chapters.

In the next lesson, we will take a look at the Docker Hub Registry.
