有多种方法可以从主机获取容器的IP

docker inspect-f“｛｛range.NetworkSettings.Networks｝｝｛｛.IPAddress｝｝｝｛｛end｝”containerID

如果您记不住上面的命令，您可以始终执行以下操作

码头工人检查集装箱ID

它将在返回信息后返回Docker对象的低级信息。查找“网络”，然后在其中找到容器的“IPAddress”

Docker inspect用于打印所有容器ip及其各自的名称

docker ps -q | xargs -n 1 docker inspect --format '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}} {{ .Name }}' | sed 's/ \// /'

此脚本将获取所有正在运行的容器的IPv4地址，而无需进一步处理或解释结果。如果您也不想要容器名称，只需删除“echo-n$name:”行即可。非常适合自动化或填充变量。

#!/bin/sh
for NAME in $(docker ps --format {{.Names}})
do
  echo -n "$NAME:"
  docker inspect $NAME | grep -i "ip.*[12]*\.[0-9]*" | \
         sed -e 's/^  *//g' -e 's/[",]//g' -e 's/[a-zA-Z: ]//g'
done

如果需要，也可以创建别名：

alias dockerip='for NAME in $(docker ps --format {{.Names}}); do echo -n "$NAME:"; docker inspect $NAME|grep -i "ip.*[12]*\.[0-9]*"|sed -e "s/^  *//g" -e "s/[*,]//g" -e "s/[a-zA-Z: ]//g"'

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",

执行：

docker ps -a

这将显示活动的docker图像：

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                       PORTS               NAMES
3b733ae18c1c        parzee/database     "/usr/lib/postgresql/"   6 minutes ago       Up 6 minutes                 5432/tcp            serene_babbage

使用CONTAINER ID值：

docker inspect <CONTAINER ID> | grep -w "IPAddress" | awk '{ print $2 }' | head -n 1 | cut -d "," -f1

"172.17.0.2"

如果您想快速查看所有Docker IP地址，或者不键入实例名称，可以破解Docker ps命令，将其添加到~/.bashrc文件中：

function docker-ips() {
    docker ps | while read line; do
        if `echo $line | grep -q 'CONTAINER ID'`; then
            echo -e "IP ADDRESS\t$line"
        else
            CID=$(echo $line | awk '{print $1}');
            IP=$(docker inspect -f "{{ .NetworkSettings.IPAddress }}" $CID);
            printf "${IP}\t${line}\n"
        fi
    done;
}
