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。

当前回答
我的多网络环境有问题,所以这是一个更动态的版本
获取驻留在一个合成文件中的所有主机名、网络和IP
for N in $(docker-compose ps -q) ; do echo "$(docker inspect -f '{{.Config.Hostname}}' ${N}) $(docker inspect -f '{{range $i, $value := .NetworkSettings.Networks}} [{{$i}}:{{.IPAddress}}]{{end}}' ${N})"; done
输出
containerA [networkA:192.168.1.4] [networkB:192.168.2.4]
containerB [networkA:192.168.1.5]
要获取所有正在运行的容器,请替换第一个命令
for N in $(docker-compose ps -q)
with
for N in $(docker container ls | awk 'NR>=2' | cut -c1-12 );
获取给定1个特定网络的1个特定容器(具有多个网络)的IP
docker inspect --format='{{range $i, $value := .NetworkSettings.Networks}}{{if eq $i "NETWORKNAME"}}{{.IPAddress}}{{end}}{{end}}' CONTAINERNAME
输出
192.168.1.4
获取给定1个特定网络的所有容器(具有多个网络)的“主机名IP”
for N in $(docker-compose ps -q) ; do echo "$(docker inspect -f '{{.Config.Hostname}}' ${N}) $(docker inspect -f '{{range $i, $value := .NetworkSettings.Networks}}{{if eq $i "intranet"}}{{.IPAddress}}{{end}}{{end}}' ${N})"; done
输出
containerA 192.168.1.4
containerB 192.168.1.5
获取给定1个特定网络的所有容器(具有多个网络)的IP
for N in $(docker-compose ps -q) ; do echo " $(docker inspect -f '{{range $i, $value := .NetworkSettings.Networks}}{{if eq $i "intranet"}}{{.IPAddress}}{{end}}{{end}}' ${N})"; done
输出
192.168.1.4
192.168.1.5

使用Python新API:
import docker
client = docker.DockerClient()
container = client.containers.get("NAME")
ip_add = container.attrs['NetworkSettings']['IPAddress']
print(ip_add)

docker inspect <container id> | grep -i ip
例如:
docker inspect 2b0c4b617a8c | grep -i ip
按名称引用容器:
docker run ... --name pg-master
然后按名称获取IP地址:
MASTER_HOST=$(docker inspect --format '{{ .NetworkSettings.IPAddress }}' pg-master)
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",

}
}
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",
