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。

如果您使用的是Windows,您可能无法从docker inspect获得任何信息,在这种情况下,您最好的选择是实际使用ipconfig/all并查找以太网适配器vEthernet(WSL):部分,在该部分您可以看到IPv4地址…:xxx.xxx.xxx.xxx(首选)-这将是您可以在本地浏览器的url中使用的IP。

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,

}
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 ${s} | jq -r 'map(.NetworkSettings.Networks) []' | grep "IPAddress";
done
/server1_web_1:
"IPAddress": "172.20.0.4",
"IPAddress": "172.18.0.5",
/server1_php_1:
"IPAddress": "172.20.0.3",
"IPAddress": "172.18.0.4",
/docker-gen:
"IPAddress": "172.18.0.3",
/nginx-proxy:
"IPAddress": "172.20.0.2",
"IPAddress": "172.18.0.2",
对于窗口10:
docker inspect --format "{{ .NetworkSettings.IPAddress }}" containerId
Docker是用Go编写的,它也使用Go语法进行查询。
要检查特定容器的IP地址,需要运行命令(-f表示“format”):
docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container_id_or_name
对于容器ID或名称,可以运行以下命令
docker container ls
它将列出每个正在运行的容器。
您可以使用docker inspect<container id>。
例如:
CID=$(docker run -d -p 4321 base nc -lk 4321);
docker inspect $CID
对于Windows容器,请使用
docker exec <container> ipconfig
其中<container>是容器的名称或id。
您可以使用docker ps来查找容器的id。
