docker容器增加端口映射 ​

1. 查看需要增加端口映射的容器信息 ​

查看当前运行的容器:

sh
[root@node1 ~]$ docker ps
CONTAINER ID   IMAGE          COMMAND                  CREATED         STATUS          PORTS                    NAMES
6f8cca028493   1e1d45f195b1   "sh -c ${SONATYPE_DI…"   15 months ago   Up 34 minutes   0.0.0.0:8081->8081/tcp   nexus

可以看到nexus当前开放了8081端口，我们想给该容器增加8082和8083两个新的端口映射，并开放8082和8083端口。

查看容器ID信息：

sh
[root@node1 ~]$ docker inspect nexus|grep Id
        "Id": "6f8cca02849370b4c271511229f36a5a0b76d20ba5b8e8391564c5d3bd0c1f44",

记住这个ID信息，后面需要用到。

查看docker数据文件存放目录：

sh
[root@master docker]# docker info|grep 'Docker Root Dir:.*'|sed 's/.*Docker Root Dir: //g'
/var/lib/docker

我们要找的容器配置文件就在/var/lib/docker/containers/6f8cca02849370b4c271511229f36a5a0b76d20ba5b8e8391564c5d3bd0c1f44目录下。

2. 停止容器和docker服务 ​

首先停止所有启动的docker容器，如我们停止nexus容器：

sh
[root@node1 ~]$ docker stop nexus
nexus

再停止docker和docker.socket服务：

sh
[root@node1 ~]$ systemctl stop docker docker.socket
[root@node1 ~]# systemctl status docker docker.socket|grep -B 1 Active
   Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; vendor preset: disabled)
   Active: inactive (dead) since Thu 2023-08-17 23:24:58 CST; 15min ago
--
   Loaded: loaded (/usr/lib/systemd/system/docker.socket; disabled; vendor preset: disabled)
   Active: inactive (dead) since Thu 2023-08-17 23:25:30 CST; 15min ago
[root@node1 ~]#

可以看到docker和docker.socket服务都已经停掉了。

3. 修改配置 ​

切换到容器对应的配置文件所在目录：

sh
[root@node1 ~]# cd /var/lib/docker/containers/6f8cca02849370b4c271511229f36a5a0b76d20ba5b8e8391564c5d3bd0c1f44
[root@node1 6f8cca02849370b4c271511229f36a5a0b76d20ba5b8e8391564c5d3bd0c1f44]# ll
total 13632
-rw-r----- 1 root root 13919914 Aug 17 23:24 6f8cca02849370b4c271511229f36a5a0b76d20ba5b8e8391564c5d3bd0c1f44-json.log
drwx------ 2 root root     4096 May 18  2022 checkpoints
-rw------- 1 root root     4407 Aug 17 23:24 config.v2.json
-rw-r--r-- 1 root root     1516 Aug 17 23:24 hostconfig.json
-rw-r--r-- 1 root root       13 Aug 17 22:48 hostname
-rw-r--r-- 1 root root      174 Aug 17 22:48 hosts
drwx-----x 2 root root     4096 May 18  2022 mounts
-rw-r--r-- 1 root root       89 Aug 17 22:48 resolv.conf
-rw-r--r-- 1 root root       71 Aug 17 22:48 resolv.conf.hash

hostconfig.json和config.v2.json就是我们需要修改的配置文件。

修改前，先进行备份。

sh
[root@node1 6f8cca02849370b4c271511229f36a5a0b76d20ba5b8e8391564c5d3bd0c1f44]# cp config.v2.json config.v2.json.bak

查看配置文件内容：

sh
[root@node1 6f8cca02849370b4c271511229f36a5a0b76d20ba5b8e8391564c5d3bd0c1f44]# cat config.v2.json

可以看到，配置文件内容是压缩后的json文件，不便于观察和修改。我们使用jq工具美化后，导入到新文件，然后再进行修改：

先修改hostconfig.jq.json配置文件，可以看到，在9行的PortBindings配置属性下，已经有一个8081端口的配置，也就是10-15行的内容，我们复制一下，然后在下面新增8082和8083端口配置：

修改完成后，查看配置内容，注意"8082/tcp"和"8083/tcp"上一行末尾的逗号不要忘记了：

sh
[root@node1 6f8cca02849370b4c271511229f36a5a0b76d20ba5b8e8391564c5d3bd0c1f44]# grep -A20 PortBindings hostconfig.jq.json
  "PortBindings": {
    "8081/tcp": [
      {
        "HostIp": "",
        "HostPort": "8081"
      }
    ],
    "8082/tcp": [
      {
        "HostIp": "",
        "HostPort": "8082"
      }
    ],
    "8083/tcp": [
      {
        "HostIp": "",
        "HostPort": "8083"
      }
    ]
  },
  "RestartPolicy": {

接着修改config.v2.jq.json, 找到ExposedPorts仿照之前内容添加端口映射:

修改后内容如下：

查看修改后的内容：

sh
[root@node1 6f8cca02849370b4c271511229f36a5a0b76d20ba5b8e8391564c5d3bd0c1f44]# grep -A4 ExposedPorts config.v2.jq.json
    "ExposedPorts": {
      "8081/tcp": {},
      "8082/tcp": {},
      "8083/tcp": {}
    },

将修改好的配置写入到默认配置中：

4. 重启docker服务和容器 ​

sh
[root@node1 ~]# systemctl start docker docker.socket
[root@node1 ~]# docker ps
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES
[root@node1 ~]# docker start nexus
nexus
[root@node1 ~]# docker ps
CONTAINER ID   IMAGE          COMMAND                  CREATED         STATUS         PORTS                              NAMES
6f8cca028493   1e1d45f195b1   "sh -c ${SONATYPE_DI…"   15 months ago   Up 2 seconds   0.0.0.0:8081-8083->8081-8083/tcp   nexus
[root@node1 ~]#

此时，查看端口监听情况：

sh
[root@node1 ~]# netstat -tunlp|grep docker
tcp        0      0 0.0.0.0:8081            0.0.0.0:*               LISTEN      7895/docker-proxy
tcp        0      0 0.0.0.0:8082            0.0.0.0:*               LISTEN      7884/docker-proxy
tcp        0      0 0.0.0.0:8083            0.0.0.0:*               LISTEN      7871/docker-proxy
[root@node1 ~]#

可以看到8082和8083端口也监听了，说明容器增加端口映射配置成功了！
