+# Docker 自定义数据储存路径
+
+将 docker 配置、数据储存在 /data/docker 文件夹中
+
+## 配置 Docker
+
+1. 查看数据储存路径（第一次）
+
+    ```shell
+    docker info | grep "Docker Root Dir"
+    ```
+
+   结果示例
+
+    ```shell
+    [root@localhost ~]# docker info | grep "Docker Root Dir"
+    Docker Root Dir: /var/lib/docker
+    [root@localhost ~]#
+    ```
+
+2. 停止 docker
+
+    ```shell
+    systemctl stop docker.socket
+    systemctl stop docker.service
+    ```
+
+3. 修改为 `/data/docker`
+
+    ```shell
+    vim /etc/docker/daemon.json
+    ```
+
+   在 `/etc/docker/daemon.json` 文件中新增 `graph`
+
+    ```shell
+    {
+        "graph": "/data/docker"
+    }
+    ```
+4. 创建 `/data/docker` 文件夹
+
+    ```shell
+    mkdir -p /data/docker
+    ```
+
+5. 查看文件夹结构（第一次）
+
+    1. 查看 `/var/lib/docker/`
+
+         ```shell
+         ll /var/lib/docker/
+         ```
+
+       结果示例
+
+        ```shell
+        [root@localhost ~]# ll /var/lib/docker/
+        total 4
+        drwx--x--x 4 root root 138 Aug  8 08:36 buildkit
+        drwx--x--- 2 root root   6 Aug  8 08:36 containers
+        -rw------- 1 root root  36 Aug  8 08:36 engine-id
+        drwx------ 3 root root  22 Aug  8 08:36 image
+        drwxr-x--- 3 root root  19 Aug  8 08:36 network
+        drwx--x--- 3 root root  40 Aug  8 08:36 overlay2
+        drwx------ 4 root root  32 Aug  8 08:36 plugins
+        drwx------ 2 root root   6 Aug  8 08:36 runtimes
+        drwx------ 2 root root   6 Aug  8 08:36 swarm
+        drwx------ 2 root root   6 Aug  8 08:36 tmp
+        drwx-----x 2 root root  50 Aug  8 08:36 volumes
+        [root@localhost ~]#
+        ```
+
+    2. 查看 `/data/docker/`
+
+         ```shell
+         ll /data/docker/
+         ```
+
+       结果示例
+
+        ```shell
+        [root@localhost ~]# ll /data/docker/
+        total 0
+        [root@localhost ~]#
+        ```
+
+6. 移动文件
+
+    ```shell
+    mv /var/lib/docker/* /data/docker/
+    ```
+
+7. 查看文件夹结构（第二次）
+
+    1. 查看 `/var/lib/docker/`
+
+         ```shell
+         ll /var/lib/docker/
+         ```
+
+       结果示例
+
+        ```shell
+        [root@localhost ~]# ll /var/lib/docker/
+        total 0
+        [root@localhost ~]#
+        ```
+
+    2. 查看 `/data/docker/`
+
+         ```shell
+         ll /data/docker/
+         ```
+
+       结果示例
+
+        ```shell
+        [root@localhost ~]# ll /data/docker/
+        total 4
+        drwx--x--x 4 root root 138 Aug  8 08:36 buildkit
+        drwx--x--- 2 root root   6 Aug  8 08:36 containers
+        -rw------- 1 root root  36 Aug  8 08:36 engine-id
+        drwx------ 3 root root  22 Aug  8 08:36 image
+        drwxr-x--- 3 root root  19 Aug  8 08:36 network
+        drwx--x--- 3 root root  40 Aug  8 08:36 overlay2
+        drwx------ 4 root root  32 Aug  8 08:36 plugins
+        drwx------ 2 root root   6 Aug  8 08:36 runtimes
+        drwx------ 2 root root   6 Aug  8 08:36 swarm
+        drwx------ 2 root root   6 Aug  8 08:36 tmp
+        drwx-----x 2 root root  50 Aug  8 08:36 volumes
+        [root@localhost ~]#
+        ```
+
+8. 建立软链接（删除 `/var/lib/docker` 文件夹）
+
+    ```shell
+    rm /var/lib/docker -rf
+    ln -s /data/docker/ /var/lib/docker
+    ```
+
+9. 查看文件夹结构（第三次）
+
+    1. 查看 `/var/lib/docker/`
+
+         ```shell
+         ll /var/lib/docker
+         ```
+
+       结果示例
+
+        ```shell
+        [root@localhost docker]# ll /var/lib/docker
+        lrwxrwxrwx 1 root root 13 Aug  8 08:43 /var/lib/docker -> /data/docker/
+        [root@localhost docker]#
+        ```
+
+    2. 查看 `/data/docker/`
+
+         ```shell
+         ll /data/docker/
+         ```
+
+       结果示例
+
+        ```shell
+        [root@localhost ~]# ll /data/docker/
+        total 4
+        drwx--x--x 4 root root 138 Aug  8 08:36 buildkit
+        drwx--x--- 2 root root   6 Aug  8 08:36 containers
+        -rw------- 1 root root  36 Aug  8 08:36 engine-id
+        drwx------ 3 root root  22 Aug  8 08:36 image
+        drwxr-x--- 3 root root  19 Aug  8 08:36 network
+        drwx--x--- 3 root root  40 Aug  8 08:36 overlay2
+        drwx------ 4 root root  32 Aug  8 08:36 plugins
+        drwx------ 2 root root   6 Aug  8 08:36 runtimes
+        drwx------ 2 root root   6 Aug  8 08:36 swarm
+        drwx------ 2 root root   6 Aug  8 08:36 tmp
+        drwx-----x 2 root root  50 Aug  8 08:36 volumes
+        [root@localhost ~]#
+        ```
+
+10. 启动 docker
+
+     ```shell
+     systemctl start docker.socket
+     systemctl start docker.service
+     ```
+
+11. 查看数据储存路径
+
+     ```shell
+     docker info | grep "Docker Root Dir"

+
+    结果示例
+
+     ```shell
+     [root@localhost ~]# docker info | grep "Docker Root Dir"
