+
+ 容器启动前需要用户自定义配置这两个配置文件，请在宿主机创建配置文件目录，并将[config目录](./config)下两个配置文件保存到该目录，示例如下：

```
+ 请按照[配置文件介绍](./doc/conf_introduction.md)自定义修改配置文件。在执行docker run命令时，需要将宿主机上自定义的配置文件目录和容器内/gala-gopher/user_conf目录映射，从而将自定义的配置信息同步到容器内。
+
+ 最后按照如下示例命令启动容器：
+
+ ```shell
+ docker run -d --name xxx -p 8888:8888 --privileged -v /etc/machine-id:/etc/machine-id -v /lib/modules:/lib/modules:ro -v /usr/src:/usr/src:ro -v /boot:/boot:ro -v /sys/kernel/debug:/sys/kernel/debug -v /sys/fs/bpf:/sys/fs/bpf -v /root/gopher_user_conf:/gala-gopher/user_conf/ -v /etc/localtime:/etc/localtime:ro --pid=host gala-gopher:0.0.1

+
+ 成功启动容器后，通过docker ps可以看到正在运行的容器：
+
+ ```shell
+ [root@localhost build]# docker ps

+ eaxxxxxxxx02 gala-gopher:0.0.1 "/bin/sh -c 'cp -f /…" About a minute ago Up About a minute 0.0.0.0:8888->8888/tcp xxx
+ ```
+
+- 获取数据
+
+ 如上步骤docker run命令中所示，我们映射了宿主机8888端口和容器的8888端口，因而可以通过8888端口获取数据来验证gala-gopher是否运行成功：
+
+ ```shell
+ [root@localhost build]# curl http://localhost:8888
+ ...
+ gala_gopher_udp_que_rcv_drops{tgid="1234",s_addr="192.168.12.34",machine_id="xxxxx",hostname="eaxxxxxxxx02"} 0 1656383357000
+ ...
+ ```
+
+ 如上有指标数据输出则证明gala-gopher运行成功。

-```shell
-docker run -d --name xxx -p 8888:8888 --privileged -v /etc/machine-id:/etc/machine-id -v /lib/modules:/lib/modules:ro -v /usr/src:/usr/src:ro -v /boot:/boot:ro -v /sys/kernel/debug:/sys/kernel/debug -v /sys/fs/bpf:/sys/fs/bpf -v /root/gopher_user_conf:/gala-gopher/user_conf/ -v /etc/localtime:/etc/localtime:ro --pid=host gala-gopher:0.0.1
-```
-
-成功启动容器后，通过docker ps可以看到正在运行的容器：
-
-```shell
-[root@localhost build]# docker ps
-CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
-eaxxxxxxxx02 gala-gopher:0.0.1 "/bin/sh -c 'cp -f /…" About a minute ago Up About a minute 0.0.0.0:8888->8888/tcp xxx
-```
-
-### 获取数据
-
-如上步骤docker run命令中所示，我们映射了宿主机8888端口和容器的8888端口，因而可以通过8888端口获取数据来验证gala-gopher是否运行成功：
-
-```shell
-[root@localhost build]# curl http://localhost:8888
-...
-gala_gopher_udp_que_rcv_drops{tgid="1234",s_addr="192.168.12.34",machine_id="xxxxx",hostname="eaxxxxxxxx02"} 0 1656383357000
-...
-```
-
-如上有指标数据输出则证明gala-gopher运行成功。
-
### 保存容器镜像
生成容器镜像后可以将镜像保存为tar文件，其他宿主机可以通过load命令导入容器镜像：
