创建新容器后,是否可以运行命令从主机获取容器的IP地址?
基本上,一旦Docker创建了容器,我就想滚动我自己的代码部署和容器配置脚本。

除非你告诉Docker,否则Docker总是在网桥网络中启动你的容器。因此,您可以尝试以下命令:
docker network inspect bridge
然后应该返回一个Containers部分,该部分将显示正在运行的容器的IP地址。
[
{
"Name": "bridge",
"Id": "40561e7d29a08b2eb81fe7b02736f44da6c0daae54ca3486f75bfa81c83507a0",
"Scope": "local",
"Driver": "bridge",
"IPAM": {
"Driver": "default",
"Options": null,
"Config": [
{
"Subnet": "172.17.0.0/16"
}
]
},
"Containers": {
"025d191991083e21761eb5a56729f61d7c5612a520269e548d0136e084ecd32a": {

"IPv4Address": "172.17.0.2/16",
"IPv6Address": ""
}
},
"Options": {
"com.docker.network.bridge.default_bridge": "true",
"com.docker.network.bridge.enable_icc": "true",
"com.docker.network.bridge.enable_ip_masquerade": "true",
"com.docker.network.bridge.host_binding_ipv4": "0.0.0.0",
"com.docker.network.bridge.name": "docker0",
"com.docker.network.driver.mtu": "1500"
}
}

如果您需要一个特定的方便别名来获取特定的容器ip,请使用此别名,并提供公认的答案
alias dockerip='f(){ docker inspect $1|grep -i "ipaddress.*[12]*\.[0-9]*"|sed -e "s/^ *//g" -e "s/[\",]//g" -e "s/[*,]//g" -e "s/[a-zA-Z: ]//g" | sort --unique; unset -f f; }; f'
然后你可以用
dockerip <containername>
您也可以使用contained而不是containername
BTW接受了很好的答案,但没有产生干净的输出,所以我编辑了它,并这样使用;
alias dockerips='for NAME in $(docker ps --format {{.Names}}); do echo -n "$NAME:"; docker inspect $NAME|grep -i "ipaddress.*[12]*\.[0-9]*"|sed -e "s/^ *//g" -e "s/[\",]//g" -e "s/[_=*,]//g" -e "s/[a-zA-Z: ]//g "| sort --unique;done'
for containerId in $(sudo docker ps -a | cut -f1 -d' ' | grep -v CONTAINER); do
echo " ContainerId - $containerId >> $(sudo docker inspect --format '{{ .NetworkSettings.IPAddress }}' $containerId) "
done
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",
docker inspect CONTAINER_ID | grep "IPAddress"
您可以将-i添加到grep中以忽略该情况,那么即使以下操作也会奏效:
docker inspect CONTAINER_ID | grep -i "IPaDDreSS"
这对我有用,我正在运行docker工具箱18.09.3,在windows 10家庭版:
键入命令“docker machine ls”
λdocker机器lsNAME活动驱动程序状态URL群集DOCKER错误default*virtualbox正在运行tcp://192.168.98.100:2376版本8.09.6
它将在URL列下显示实际IP。例如,“192.168.98.100”
