Explanation
Pushing Images Using the Docker CLI:
You use the Docker CLI to push images to Oracle Cloud Infrastructure Registry.
To push an image, you first use the docker tag command to create a copy of the local source image as a new image (the new image is actually just a reference tothe existing source image). As a name for the new image, you specify the fully qualified path to the target location in Oracle Cloud Registry where you want to push the image, optionally including the name of a repository.
For example, assume you have a local image named acme-web-app:latest. Let's say you want to push this image to Oracle Cloud Infrastructure Registry with a name of acme-web-app:version2.0.test into a repository called project01 in the Ashburn region of the acme-dev tenancy. When you use the docker tag command, you'd name the new image with the fully qualified path to its destination, in the format <region-key>.ocir.io/<tenancy-namespace>/<repo-name>/<image-name>:<tag>. So in this case, you'd name the new image iad.ocir.io/ansh81vru1zp/project01/acme-web-app:version2.0.test. Subsequently, when you use the docker push command, the image's name ensures it is pushed to the correct destination.
To push images to Oracle Cloud Infrastructure Registry using the Docker CLI:
If you already have an auth token, go to the next step. Otherwise:
In the top-right corner of the Console, open the Profile menu () and then click User Settings to view the
details.
On the Auth Tokens page, click Generate Token.
Enter a friendly description for the auth token.Avoid entering confidential information.
Click Generate Token. The new auth token is displayed.
Copy the auth token immediately to a secure location from where you can retrieve it later, because you won't see the auth token again in the Console.
Close theGenerate Token dialog.
