Label

Label

LABEL <key>=<value> <key>=<value> <key>=<value> ...

Label指令为镜像添加元数据。Label是key-value对。

例子:

LABEL "com.example.vendor"="ACME Incorporated"
LABEL com.example.label-with-value="foo"
LABEL version="1.0"
LABEL description="This text illustrates \
that label-values can span multiple lines."

通过一个LABEL命令指定多个kv对,避免镜像层次过多。

LABEL multi.label1="value1" multi.label2="value2" other="value3"
LABEL multi.label1="value1" \
      multi.label2="value2" \
      other="value3"

MAINTAINER

MAINTAINER <name>

该指令已经废弃。使用LABEL指令。

LABEL maintainer="SvenDowideit@home.org.au"
