problem has been solved：unauthorized: authentication required . I suggest you change the code.

[donotknowsjtu]

problem:

Run docker login -u $ALIYUN_REGISTRY_USER -p $ALIYUN_REGISTRY_PASSWORD $ALIYUN_REGISTRY
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
Error response from daemon: Get "https://***/v2/": unauthorized: authentication required
Error: Process completed with exit code 1.

problem analysis:
this maybe your syntax wrong
solution:
将code中的.github/workflows/docker.yaml中第六十行的: docker login -u $ALIYUN_REGISTRY_USER -p $ALIYUN_REGISTRY_PASSWORD $ALIYUN_REGISTRY 更改为：echo "${{ secrets.ALIYUN_REGISTRY_PASSWORD }}" | docker login -u "${{ secrets.ALIYUN_REGISTRY_USER }}" --password-stdin "${{ secrets.ALIYUN_REGISTRY }}"
