我用这个简单的方法

docker exec -it <container id or name> hostname -i

e.g

ubuntu@myhost:~$ docker exec -it 3d618ac670fe hostname -i
10.0.1.5

我必须通过docker容器名称提取docker容器IP地址，以便在部署脚本中进一步使用。为此，我编写了以下bash命令：

docker inspect $(sudo docker ps | grep my_container_name | head -c 12) | grep -e \"IPAddress\"\:[[:space:]]\"[0-2] | grep -o '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}'

假设将其放置到bash脚本中会很方便，该脚本会期望my_container_name作为参数。。。

Use:

docker inspect $CID | grep IPAddress | grep -v null| cut -d '"' -f 4 | head -1

接受的答案对于每个容器的多个网络不适用：

> docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' cc54d96d63ea

172.20.0.4172.18.0.5

下一个最佳答案更接近：

> docker inspect cc54d96d63ea | grep "IPAddress"

"SecondaryIPAddresses": null,
"IPAddress": "",
    "IPAddress": "172.20.0.4",
    "IPAddress": "172.18.0.5",

我喜欢使用jq解析网络JSON：

> docker inspect cc54d96d63ea | jq -r 'map(.NetworkSettings.Networks) []'

{
  "proxy": {
    "IPAMConfig": null,
    "Links": [
      "server1_php_1:php",
      "server1_php_1:php_1",
      "server1_php_1:server1_php_1"
    ],
    "Aliases": [
      "cc54d96d63ea",
      "web"
    ],
    "NetworkID": "7779959d7383e9cef09c970c38c24a1a6ff44695178d314e3cb646bfa30d9935",
    "EndpointID": "4ac2c26113bf10715048579dd77304008904186d9679cdbc8fcea65eee0bf13b",
    "Gateway": "172.20.0.1",
    "IPAddress": "172.20.0.4",
    "IPPrefixLen": 24,
    "IPv6Gateway": "",
    "GlobalIPv6Address": "",
    "GlobalIPv6PrefixLen": 0,
    "MacAddress": "02:42:ac:14:00:04",
    "DriverOpts": null
  },
  "webservers": {
    "IPAMConfig": null,
    "Links": [
      "server1_php_1:php",
      "server1_php_1:php_1",
      "server1_php_1:server1_php_1"
    ],
    "Aliases": [
      "cc54d96d63ea",
      "web"
    ],
    "NetworkID": "907a7fba8816cd0ad89b7f5603bbc91122a2dd99902b504be6af16427c11a0a6",
    "EndpointID": "7febabe380d040b96b4e795417ba0954a103ac3fd37e9f6110189d9de92fbdae",
    "Gateway": "172.18.0.1",
    "IPAddress": "172.18.0.5",
    "IPPrefixLen": 24,
    "IPv6Gateway": "",
    "GlobalIPv6Address": "",
    "GlobalIPv6PrefixLen": 0,
    "MacAddress": "02:42:ac:12:00:05",
    "DriverOpts": null
  }
}

要列出每个容器的IP地址，则变成：

for s in `docker ps -q`; do
  echo `docker inspect -f "{{.Name}}" ${s}`:
  docker inspect ${s} | jq -r 'map(.NetworkSettings.Networks) []' | grep "IPAddress";
done

/server1_web_1:
    "IPAddress": "172.20.0.4",
    "IPAddress": "172.18.0.5",
/server1_php_1:
    "IPAddress": "172.20.0.3",
    "IPAddress": "172.18.0.4",
/docker-gen:
    "IPAddress": "172.18.0.3",
/nginx-proxy:
    "IPAddress": "172.20.0.2",
    "IPAddress": "172.18.0.2",

只需一个命令即可获取所有容器名称及其IP地址。

docker inspect -f '{{.Name}} - {{.NetworkSettings.IPAddress }}' $(docker ps -aq)

如果您使用docker compose，则命令如下：

docker inspect -f '{{.Name}} - {{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $(docker ps -aq)

输出将为：

/containerA - 172.17.0.4
/containerB - 172.17.0.3
/containerC - 172.17.0.2

将此shell脚本添加到~/.bashrc或相关文件中：

docker-ip() {
  docker inspect --format '{{ .NetworkSettings.IPAddress }}' "$@"
}

然后，要获取容器的IP地址，只需执行以下操作：

docker-ip YOUR_CONTAINER_ID

对于Docker的新版本，请使用以下内容：

docker-ip() {
        docker inspect --format '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' "$@"
}
