Why Does an Image Fail to Be Uploaded Through SWR Console?

Invalid Image Format or Authentication Failed

Symptom: When you upload an image to SWR through the SWR console, an error message is displayed, indicating that the image format is invalid.

Possible cause: Invalid image address leads to upload failure.

The image tag, which is at the end of an image address, can be omitted. When it is omitted, the latest version of the image will be pushed. Other parts of the image address cannot be omitted. Ensure that they are all correctly configured.

Example: swr.cn-north-4.myhuaweicloud.com/repo_namespace/repo_name:tag

• swr.cn-north-4.myhuaweicloud.com indicates the SWR image repository address.
• repo_namespace: organization name. It contains a maximum of 64 characters and must meet regular expression ^([a-z]+(?:(?:(?:_|__|[-]*)[a-z0-9]+)+)?)$.
• repo_name:tag: image name and tag. The image name contains a maximum of 128 characters and must meet regular expression ^([a-z0-9]+(?:(?:(?:_|__|[-]*)[a-z0-9]+)+)?)$.

To view the image address, decompress the image. Open the manifest.json file, and check the value of RepoTags.

Solution: Tag the image again according to the naming rules. Run the docker save command, and upload the image on the SWR console.

It is the image name in the repositories and manifest.json files that should be checked and modified rather than the name of the image file you select and upload on the SWR console.

Stuck at the Upload Page Until It Times Out

Symptom: When you upload an image to SWR through the SWR console, the upload progress is stuck and the upload task times out at the end.

Possible Causes:

• Invalid image name leads to upload failure.
• If you upload an image using the SWR console, it is uploaded over public networks. Unstable networks can lead to upload failure.

Solutions:

• Modify the image name according to the naming rules, and try uploading the image again.
• Change the network environment or use the container engine client to upload the image.
