从docker inspect获取标签值 [英] get label value from docker inspect

问题描述

由于键具有，我在从地图列表中获取值时遇到问题。

I had problem to get the value from the map list due to the key has "." inside.

docker inspect jenkins
...
  Config: {
  ..
      "Labels": {
            "com.docker.compose.config-hash": "85bcf1e0bcd708120185a303e2a8d8e65543c1ec77ec0c6762fc057dc10320aa",
            "com.docker.compose.container-number": "1",
            "com.docker.compose.oneoff": "False",
            "com.docker.compose.project": "new",
            "com.docker.compose.service": "sc2",
            "com.docker.compose.version": "1.5.2"
        }
    }
}

我可以获取地图列表

docker inspect -f {{.Config.Labels}} new_sc2_1
map[com.docker.compose.config-hash:85bcf1e0bcd708120185a303e2a8d8e65543c1ec77ec0c6762fc057dc10320aa com.docker.compose.container-number:1 com.docker.compose.oneoff:False com.docker.compose.project:new com.docker.compose.service:sc2 com.docker.compose.version:1.5.2]

但是我如何获得项目名e new 来自键 com.docker.compose.project

But how can I get the project name new from key com.docker.compose.project

docker inspect -f {{.Config.Labels.com.docker.compose.project}} new_sc2_1
<no value>

推荐答案

您可以使用 index 获取该密钥的值（为便于阅读而包装）；

You can use index to get the value of that key (wrapped for readability);

docker inspect \
  --format '{{ index .Config.Labels "com.docker.compose.project"}}' \
  new_sc2_1

那应该给您项目的名称
