• No.

Describe the feature you would like.

• Proxy Dockerfile uses the obsolete MAINTAINER tag and Legacy Key Value Format. Refer to https://docs.docker.com/reference/build-checks/maintainer-deprecated/ and https://docs.docker.com/reference/build-checks/legacy-key-value-format/ .
• See
  • https://github.com/apache/shardingsphere/blob/master/distribution/proxy/Dockerfile
  • https://github.com/apache/shardingsphere/blob/master/distribution/proxy-native/Dockerfile
• I think for the following tags,

MAINTAINER ShardingSphere "[email protected]"

• should be replaced with something like https://gitlab.com/gitlab-org/omnibus-gitlab/-/commit/94105c86fbb266a7e45f7b9c7eebac066ca2a7be ,

LABEL org.opencontainers.image.authors="ShardingSphere [email protected]"

• For statements like the following,

ENV LOCAL_PATH /opt/shardingsphere-proxy

• Should be replaced by,

ENV LOCAL_PATH=/opt/shardingsphere-proxy
