Image Management Overview

SWR provides free, shared image repositories with unlimited storage capacity. These repositories offer full-lifecycle image management for your images.

• Pushing images: Pushing images (also called uploading images) helps you push local images to an SWR image repository, so that you can manage images more conveniently. You can use either a container engine client or the SWR console to push your images. Currently, there are two types of container engine clients: Docker and containerd.
• Pulling images: Pulling images (also called downloading images) is the process of obtaining images from an image repository. Then, you can use the images to deploy containerized applications in CCE or CCI.
• Logging in to or connecting to SWR: Before pushing or pulling images using a container engine client, you need to connect to SWR. You can use a temporary or long-term command to connect to SWR.
• Modifying images: After images are uploaded, they are private by default. You can modify image attributes, including image type (public or private), category, and description.
• Sharing images: After images are uploaded, you can share private images with other accounts and grant them the permission to download the shared images.
• Adding image triggers: SWR often works with CCE or CCI to enable automatic application updates. You can add a trigger to automatically update the application that uses the image when the image tag is updated.
• Adding image retention policies: After images are pushed, you can add retention policies to automatically delete any unused images. There are policies based on the number of image retention days and policies based on the number of image tags.
• Synchronizing images: After images are uploaded, you can synchronize images of the latest tags to the image repository in another region. Both manual synchronization and automatic synchronization are supported.
• Scanning images: You can scan your private images to check for vulnerabilities in just a few clicks and follow the suggestions to keep images safe.
• Image Center: SWR provides a large number of public images. You can add public images to your favorites and push them to your repository.
