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
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",

},
"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",

对于窗口10：
docker inspect --format "{{ .NetworkSettings.IPAddress }}" containerId
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
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'

我的回答：
docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}} %tab% {{.Name}}' $(docker ps -aq
) | sed 's#%tab%#\t#g' | sed 's#/##g' | sort -t . -k 1,1n -k 2,2n -k 3,3n -k 4,4n
也可以作为bash别名：
docker-ips() { docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}} %tab% {{.Name}}' $(docker ps -aq) | sed 's#%tab%#\t#g' | sed 's#/##g' | sort -t . -k 1,1n -k 2,2n -k 3,3n -k 4,4n }
输出按IP地址排序，制表符分隔：
# docker-ips
172.18.0.2 memcached
172.18.0.3 nginx
172.18.0.4 fpm-backup
172.18.0.5 dns
172.18.0.6 fpm-beta
172.18.0.7 exim
172.18.0.8 fpm-delta
172.18.0.9 mariadb
172.18.0.10 fpm-alpha
172.19.0.2 nextcloud-redis
172.19.0.3 nextcloud-db
172.19.0.4 nextcloud
