1、docker-compose yaml指定具体容器网桥ip网段subnet

docker-compose 启动yaml有时可能的容器网段与宿主机的ip冲突导致宿主机上不了网，这时候可以更改yaml指定subnet

宿主机内网一般是192**，这时候容器可以指定172*

version: '3.9'
services:coredns:image: coredns/coredns:1.10.0container_name: corednsports:- 53:53/udpnetworks:mynetwork:ipv4_address: 172.28.0.4volumes:- ./coredns/hostsfile:/etc/coredns/hostsfile- ./coredns/Corefile:/Corefilenetworks:mynetwork1:driver: bridgeipam:driver: defaultconfig:- subnet: 172.28.0.0/16gateway: 172.28.0.1

案例：

subnet 关键字设置了容器的网桥 IP 网段为 192.168.0.0/16，其中 ipv4_address 指定了容器的 IP 地址为 192.168.0.2。

version: '3'
services:myservice:image: <image>networks:mynetwork:ipv4_address: 192.168.0.2networks:mynetwork:driver: bridgeipam:config:- subnet: 192.168.0.0/16

2、docker指定subnet

1）先创建自定义网络

docker network create --subnet=172.18.0.0/16 shadownet

2）运行docker指定具体net

docker run --net shadownet  -p 6008:6008 registry.cn-hangzhou.aliyuncs.com/fastgpt_docker/m3e-large-api

3）查看容器ip
可以看到分到的ip是指定的172.18网段下面ip **0.2

docker inspect 0418bea8c6aecd3af266eb1

3、上面2把转出docker compose yml文件运行

1）首先相同网段名会冲突可以先删除前面的docker network rm shadownet；也可以换个名称和网段
2）运行指定yml：docker-compose -f C:\Users\loong\Downloads\subnet.yml up

subnet.yml

version: '3'
services:myservice:image: registry.cn-hangzhou.aliyuncs.com/fastgpt_docker/m3e-large-apiports:- 6008:6008networks:- shadownetnetworks:shadownet:driver: bridgeipam:config:- subnet: 172.18.0.0/16

3、docker取消自启动

https://stackoverflow.com/questions/37599128/docker-how-do-you-disable-auto-restart-on-a-container

–restart=always 下面更改

docker update --restart=no <container_name_or_id>

查看是否取消成功

docker inspect -f '{{.HostConfig.RestartPolicy.Name}}' <container_name_or_id>
