# 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"
|
||
```
|
||
|
||
