Migrating Images to SWR Using Docker Commands

Scenarios

SWR provides easy-to-use image hosting and efficient distribution services. If a small quantity of images need to be migrated, enterprises can use the docker pull/push command to migrate images to SWR.

Procedure

1. Pull images from the source repository.

   Run the docker pull command to pull the images.

   Example: docker pull nginx:latest

   Run the docker images command to check whether the images are successfully pulled.

   # docker images
   REPOSITORY                        TAG       IMAGE ID       CREATED         SIZE
   nginx                             latest    22f2bf2e2b4f   5 hours ago     22.8MB

2. Push the images pulled in 1 to SWR.
   1. Log in to the VM where the destination container is located and log in to SWR.
   2. Tag the images.

      docker tag [Image name:Tag name] [Image repository address]/[Organization name]/[Image name:Tag name]

   3. Run the following command to push the images to the destination image repository.

      docker push [image-repository-address]/[organization-name]/[image-name:tag-name]

   4. Check whether the following information is returned. If yes, the push is successful.
