這篇文章主要介紹了Docker怎么查看正在運行的容器目錄的相關知識，內容詳細易懂，操作簡單快捷，具有一定借鑒價值，相信大家閱讀完這篇Docker怎么查看正在運行的容器目錄文章都會有所收獲，下面我們一起來看看吧。
為了方便操作服務器，大部分都是使用寶塔面板操作的，在寶塔中我發現面板中用來管理Docker的工具使用起來非常方便
如下圖：
可以看到寶塔的面板可以直接查看和從操作容器、Compose 、Compose 模板、鏡像、網絡、存儲卷、倉庫等，但是本文主要說說在管理容器的面板有一個操作 【目錄】
點擊之后可以直接進入到容器的內部，查看目錄地址發現其實就是服務器本地一個文件目錄
/var/lib/docker/overlay2/這個目錄其實就是Docker容器掛載點，找到容器的掛載后就很方便了，以后復制宿主機文件到容器內部沒必要使用命令了。
從宿主機傳輸文件夾到 Docker 中的命令
docker cp 需要傳輸的文件路徑 docker名字:docker中放置文件的位置
示例：
# 將宿主機 ik 文件夾復制到名為 address_platform_pj 的容器中的 /usr/local/elasticsearch-7.3.0/plugins 路徑下面 docker cp /tmp/ik address_platform_pj:/usr/local/elasticsearch-7.3.0/plugins
上面介紹的是用寶塔面板可以直接看到容器掛載點，下面介紹如何使用命令找到容器的掛載點。
需要借助 docker inspect 命令
格式
docker inspect 容器名稱/容器ID
在Docker中，一個很重要的概念就是GraphDriver，它主要用于管理和維護鏡像，包括把鏡像從倉庫下載下來，到運行時把鏡像掛載起來可以被容器訪問等，都是GraphDriver去完成的。
下面是我們運行的一個rabbitmq容器，我們可以看一下他的GraphDriver，注意這里用的docker存儲驅動是overlay2

]可以看到容器的元數據特別的多，這里我們使用grep命令來檢索GraphDriver(圖形驅動程序),只展示8行主要信息
docker inspect rabbitmq | grep GraphDriver -A 8
示例：

},

},通過查看容器詳情的GraphDriver.Data，我們可以知道有下面幾個重要目錄
LowerDir：image 鏡像層(鏡像本身，只讀)
UpperDir：容器的上層(讀寫)
MergedDir：容器的文件系統，使用Union FS（聯合文件系統）將lowerdir 和upperdir 合并給容器使用
WorkDir：容器在 宿主機的工作目錄
所以，每一個容器運行的分層的文件系統，其實都可以在宿主機中找到對應的(通常在docker安裝目錄下/var/lib/docker/overlay2)
而MergedDir就是我們要找的容器掛載點，我們可以直接進入到該目錄下：
[root@iZbp1dg7mun11n29b6ndm6Z lib]# cd /var/lib/docker/overlay2/346e18c0e8e1bc04f3be2d7c848dbedd25ddd63639ff41ce6e19c8936e711db6/merged [root@iZbp1dg7mun11n29b6ndm6Z merged]# ls bin boot dev etc home lib lib32 lib64 libx32 media mnt opt plugins proc root run sbin srv sys tmp usr var
既然知道了容器的掛載點，我們可以使用Xftp或者其它工具，直接將想要放到容器的文件丟在上面傳輸，方便快捷，一步到位！
