# LABEL 指令
|
|||
|
|
|
|||
|
|
`LABEL` 指令用来给镜像以键值对的形式添加一些元数据（metadata）。
|
|||
|
|
|
|||
|
|
```docker
|
|||
|
|
LABEL <key>=<value> <key>=<value> <key>=<value> ...
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
我们还可以用一些标签来申明镜像的作者、文档地址等：
|
|||
|
|
|
|||
|
|
```docker
|
|||
|
|
LABEL org.opencontainers.image.authors="yeasy"
|
|||
|
|
|
|||
|
|
LABEL org.opencontainers.image.documentation="https://yeasy.gitbooks.io"
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
