一、配置overlay类型网络准备工作
1、在luoahong3主机上
docker run -d -p 8500:8500 -h consul --name consul progrium/consul -server -bootstrap [root@luoahong3 ~]# docker run -d -p 8500:8500 -h consul --name consul progrium/consul -server -bootstrap

2、在luoahong主机上
vim /etc/docker/daemon.json
{
"hosts":["tcp://0.0.0.0:2376","unix:///var/run/docker.sock"],
"cluster-store": "consul://192.168.231.138:8500",
"cluster-advertise": "192.168.231.136:2376",
"insecure-registries": ["192.168.231.136:5000"]
} systemctl restart docker
可能会报错解决方案如下
vim /usr/lib/systemd/system/docker.service
ExecStart=/usr/bin/dockerd
systemctl daemon-reload
systemctl restart docker
3、在luoahong1主机上
vim /etc/docker/daemon.json
{
"hosts":["tcp://0.0.0.0:2376","unix:///var/run/docker.sock"],
"cluster-store": "consul://192.168.231.138:8500",
"cluster-advertise": "192.168.231.137:2376",
"insecure-registries": ["192.168.231.136:5000"]
} systemctl restart docker
可能会报错解决方案如下
vim /usr/lib/systemd/system/docker.service
ExecStart=/usr/bin/dockerd
systemctl daemon-reload
systemctl restart docker
4、测试截图
一、创建网络启动容器
1、创建overlay网络
docker network create -d overlay ol3
2、启动容器测试
docker run -it --network ol3 --name oldboy02 busybox:latest /bin/sh
3、测试截图
