This topic describes the basic concepts of Docker container images to help you better use Container Registry.
registryis where Docker images are stored.
Before pulling your private image from a registry, you must log on to the
registry. After you modify the image, you can push it back to the
registry. Alternatively, you can build a Docker image locally and push it to the
- Docker image URL
For example, the URL of a public image of Container Service is as follows:
registry.cn-hangzhou.aliyuncs.com: the domain name of the registry.
acs: the name of your namespace.
agent: the name of your repository.
0.8: the tag of the image. This field is optional. Default value: latest.
The preceding fields can be combined to form the following terms:
registry.cn-hangzhou.aliyuncs.com/acs/agent: the location of the repository.
acs/agent: the full name of the repository, which is used to call API operations.
