Uploading an Image Through a Container Engine Client (Recommended)

Scenario

Uploading an image through a container engine client is to run docker push on the server where the client is installed to push the image to SWR.

If your container engine client is an ECS or CCE node, you can push an image over two types of networks.

If your client and the image repository are in the same region, you can push an image over private networks.
If your client and the image repository are in different regions, you can push an image over public networks and the client needs to be bound to an EIP.

Notes and Constraints

Each image layer cannot exceed 10 GB.
Your container engine client version must be 1.11.2 or later.

Prerequisite

You have created an organization in SWR. For details, see Creating an Organization.

Procedure

Building a Container Image or Importing an Image File.
Access SWR.
1. Log in to the SWR console.
2. In the navigation pane on the left, choose Dashboard and click Generate Login Command in the upper right corner. On the displayed page, click to copy the login command.
  Figure 1 Generating a login command
  - A temporary login command is valid for 6 hours. For details about how to obtain a login command that will remain valid for a long term, see Obtaining a Long-Term Valid Login Command. After you obtain a long-term valid login command, your temporary login commands will still be valid as long as they are in their validity periods.
  - The domain name at the end of the login command is the image repository address. Record the address for later use.
3. Run the login command on your container engine client.
  The message Login Succeeded will be displayed upon a successful login.
Run the following command on the device where the container engine is installed to label the Nginx image:

docker tag [Image name 1:tag 1][Image repository address]/[Organization name]/[Image name 2:tag 2]

In the preceding information:
- [Image name 1:tag 1]: Replace it with the actual name and tag of the image to be uploaded.
- [Image repository address]: You can query the address on the SWR console, that is, the domain name at the end of the login command in 2.b.
- [Organization name]: Replace it with the name of the organization created.
- [Image name 2:tag 2]: Replace it with the desired image name and tag.
Examples:

docker tag nginx:v1 swr.ap-southeast-1.myhuaweicloud.com/cloud-develop/nginx:v1
Run the following command to push the image to the image repository:

docker push [Image repository address]/[Organization name]/[Image name 2:tag 2]

Examples:

docker push swr.ap-southeast-1.myhuaweicloud.com/cloud-develop/nginx:v1

The following information will be returned upon a successful push:
```
The push refers to repository [swr.ap-southeast-1.myhuaweicloud.com/cloud-develop/nginx:v1]
