MaintainerDeprecated#

Output#

MAINTAINER instruction is deprecated in favor of using label

Description#

The MAINTAINER instruction, used historically for specifying the author of the Dockerfile, is deprecated. To set author metadata for an image, use the org.opencontainers.image.authors OCI label.

Examples#

❌ Bad: don't use the MAINTAINER instruction

MAINTAINER [email protected]

✅ Good: specify the author using the org.opencontainers.image.authors label

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