Docker查看正在运行的容器目录
作者：mmseoamin日期：2024-01-24
起因
为了方便操作服务器，大部分都是使用宝塔面板操作的，在宝塔中我发现面板中用来管理Docker的工具使用起来非常方便，如下图：
可以看到宝塔的面板可以直接查看和从操作容器、Compose 、Compose 模板、镜像、网络、存储卷、仓库等，但是本文主要说说在管理容器的面板有一个操作 【目录】
点击之后可以直接进入到容器的内部，查看目录地址发现其实就是服务器本地一个文件目录
/var/lib/docker/overlay2/这个目录其实就是Docker容器挂载点，找到容器的挂载后就很方便了，以后复制宿主机文件到容器内部没必要使用命令了。
从宿主机传输文件夹到 Docker 中的命令
docker cp 需要传输的文件路径 docker名字:docker中放置文件的位置
示例：
# 将宿主机 ik 文件夹复制到名为 address_platform_pj 的容器中的 /usr/local/elasticsearch-7.3.0/plugins 路径下面 docker cp /tmp/ik address_platform_pj:/usr/local/elasticsearch-7.3.0/plugins
如何查看容器挂载点
上面介绍的是用宝塔面板可以直接看到容器挂载点，下面介绍如何使用命令找到容器的挂载点。
需要借助 docker inspect 命令
菜鸟原文
格式
docker inspect 容器名称/容器ID
在Docker中，一个很重要的概念就是GraphDriver，它主要用于管理和维护镜像，包括把镜像从仓库下载下来，到运行时把镜像挂载起来可以被容器访问等，都是GraphDriver去完成的。
下面是我们运行的一个rabbitmq容器，我们可以看一下他的GraphDriver，注意这里用的docker存储驱动是overlay2

可以看到容器的元数据特别的多，这里我们使用grep命令来检索GraphDriver(图形驱动程序),只展示8行主要信息
docker inspect rabbitmq | grep GraphDriver -A 8
示例：
[root@iZbp1dg7mun11n29b6ndm6Z ~]# docker inspect rabbitmq | grep GraphDriver -A 8
"GraphDriver": {
"Data": {
"LowerDir": "/var/lib/docker/overlay2/346e18c0e8e1bc04f3be2d7c848dbedd25ddd63639ff41ce6e19c8936e711db6-init/diff:/var/lib/docker/overlay2/d1f57dc40a37ea144eda52008ce77c6a204315fd463503ebb44d738f9def02d6/diff:/var/lib/docker/overlay2/94e59be20d43ea92c6db5d340e4e487aa48173f4c437ac301cf3020231ef53df/diff:/var/lib/docker/overlay2/91ebb4d307f75386fbfa2c870770cebba9f9cec0e88c3204758386bd7231b0f9/diff:/var/lib/docker/overlay2/26ae282efeabcfc1e1b0b487a2550d7ca1504048e58fd6a244835b9616b9b3af/diff:/var/lib/docker/overlay2/55d42966a32b217c6b97ac2b04fe56a8b1434538c78abda79a1fe01cef7d7570/diff:/var/lib/docker/overlay2/b37a30724d2e5cda683b3646dfdaa589661da410e29331fd5d0396eb9a5aaa29/diff:/var/lib/docker/overlay2/487d3efd72670cb9762b0d7abc407f152f5bf39a5777cf353fc325bd79acbf19/diff:/var/lib/docker/overlay2/9bbf703d2ce4a6d1d78cc443297250cca265a1a1204620eabe104358372b5e4a/diff:/var/lib/docker/overlay2/925b67bb37abd8a6d62c5188e66f0bd28d308d10274e13ccf88bb9d1449a1fb6/diff",

"UpperDir": "/var/lib/docker/overlay2/346e18c0e8e1bc04f3be2d7c848dbedd25ddd63639ff41ce6e19c8936e711db6/diff",

通过查看容器详情的GraphDriver.Data，我们可以知道有下面几个重要目录
- LowerDir：image 镜像层(镜像本身，只读)
- UpperDir：容器的上层(读写)
- MergedDir：容器的文件系统，使用Union FS（联合文件系统）将lowerdir 和upperdir 合并给容器使用
- WorkDir：容器在 宿主机的工作目录
所以，每一个容器运行的分层的文件系统，其实都可以在宿主机中找到对应的(通常在docker安装目录下/var/lib/docker/overlay2)
而MergedDir就是我们要找的容器挂载点，我们可以直接进入到该目录下：
[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
高效传输文件到Docker容器
既然知道了容器的挂载点，我们可以使用Xftp或者其它工具，直接将想要放到容器的文件丢在上面传输，方便快捷，一步到位！
