作用
獲取容器/映象的元資料（JSON格式）
語法格式
docker inspect [OPTIONS] NAME|ID [NAME|ID...]
options 說明
| option | 說明 |
| -f | 指定返回值的模板檔案 |
| -s | 如果型別為容器，則顯示檔案總大小 |
| --type | 返回指定型別的JSON |
實際栗子
獲取容器 IP
docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $CONTAINER_ID
簡單版本
docker inspect tomcat7 | grep IPAddress
就是內容會多了點，但有輸出關鍵資訊就行
獲取容器 MAC 地址
docker inspect --format='{{range .NetworkSettings.Networks}}{{.MacAddress}}{{end}}' $CONTAINER_ID
簡單版本
docker inspect tomcat7 | grep MacAddress
萬物皆可 grep 哈哈哈
獲取容器日誌路徑
docker inspect --format='{{.LogPath}}' $CONTAINER_ID
獲取容器的元資料
docker inspect tomcat7
結果
