Docker查看正在运行的容器目录

起因

在这里插入图片描述
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

dockercp 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dockercp /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

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 -A8

                "WorkDir":"/var/lib/docker/overlay2/346e18c0e8e1bc04f3be2d7c848dbedd25ddd63639ff41ce6e19c8936e711db6/work"},
            "Name":"overlay2"},

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！
