擴(kuò)展描述
ker檢查提供了由Docker控制的構(gòu)造的詳細(xì)信息。
默認(rèn)情況下，docker inspect會(huì)將結(jié)果呈現(xiàn)在JSON數(shù)組中。
實(shí)例
獲取實(shí)例的 IP 地址
在大多數(shù)情況下，您可以以相當(dāng)簡(jiǎn)單的方式從 JSON 中選擇任何字段。
$ docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $INSTANCE_ID獲取實(shí)例的 MAC 地址
$ docker inspect --format='{{range .NetworkSettings.Networks}}{{.MacAddress}}{{end}}' $INSTANCE_ID獲取實(shí)例的日志路徑
$ docker inspect --format='{{.LogPath}}' $INSTANCE_ID獲取實(shí)例的圖像名稱
$ docker inspect --format='{{.Config.Image}}' $INSTANCE_ID列出所有端口綁定
可以循環(huán)遍歷結(jié)果中的數(shù)組和映射以生成簡(jiǎn)單的文本輸出：
$ docker inspect --format='{{range $p, $conf := .NetworkSettings.Ports}} {{$p}} -> {{(index $conf 0).HostPort}} {{end}}' $INSTANCE_ID查找特定的端口映射
在.Field當(dāng)字段名稱以數(shù)字開頭，但模板語(yǔ)言的語(yǔ)法不工作index的功能一樣。該.NetworkSettings.Ports部分包含內(nèi)部端口映射到外部地址/端口對(duì)象列表的映射。要抓取數(shù)字公共端口，您可以使用它index來(lái)查找特定端口映射，然后在index其中包含第一個(gè)對(duì)象。然后我們要求HostPort現(xiàn)場(chǎng)獲得公開地址。
$ docker inspect --format='{{(index (index .NetworkSettings.Ports "8787/tcp") 0).HostPort}}' $INSTANCE_ID獲取 JSON 格式的分段
如果您請(qǐng)求一個(gè)本身是包含其他字段的結(jié)構(gòu)的字段，默認(rèn)情況下，您將得到內(nèi)部值的 Go 樣式轉(zhuǎn)儲(chǔ)。Docker 添加了一個(gè)模板函數(shù)，json，它可以應(yīng)用于以 JSON 格式獲得結(jié)果。
$ docker inspect --format='{{json .Config}}' $INSTANCE_ID
