boot mes ports usr unable network oot tcp 解決方案
一、配置overlay類型網絡準備工作
1、在luoahong3主機上
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 Unable to find image ‘progrium/consul:latest‘ locally latest: Pulling from progrium/consul c862d82a67a2: Pull complete 0e7f3c08384e: Pull complete 0e221e32327a: Pull complete 09a952464e47: Pull complete 60a1b927414d: Pull complete 4c9f46b5ccce: Pull complete 417d86672aa4: Pull complete b0d47ad24447: Pull complete fd5300bd53f0: Pull complete a3ed95caeb02: Pull complete d023b445076e: Pull complete ba8851f89e33: Pull complete 5d1cefca2a28: Pull complete Digest: sha256:8cc8023462905929df9a79ff67ee435a36848ce7a10f18d6d0faba9306b97274 Status: Downloaded newer image for progrium/consul:latest 485d84362a1d7b3e3c0df34451cb8d228abd1f15487a9ec94dc6c6c9f93d60b5 [root@luoahong3 ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 485d84362a1d progrium/consul "/bin/start -server …" About a minute ago Up About a minute 53/tcp, 53/udp, 8300-8302/tcp, 8400/tcp, 8301-8302/udp, 0.0.0.0:8500->8500/tcp consul
2、在luoahong主機上
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
可能會報錯解決方案如下
vim /usr/lib/systemd/system/docker.service ExecStart=/usr/bin/dockerd systemctl daemon-reload systemctl restart docker
3、在luoahong1主機上
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
可能會報錯解決方案如下
vim /usr/lib/systemd/system/docker.service ExecStart=/usr/bin/dockerd systemctl daemon-reload systemctl restart docker
4、測試截圖
一、創建網絡啟動容器
1、創建overlay網絡
docker network create -d overlay ol3
2、啟動容器測試
docker run -it --network ol3 --name oldboy02 busybox:latest /bin/sh
3、測試截圖
三、overlay類型網絡原理圖
