如何使用docker-compose将docker容器相互链接
如何使用docker-compose将docker容器相互链接
提问于 2015-03-28 02:23:09
我必须用docker-compose设置一个mongo副本集。对于副本集，容器必须相互了解。
我在docker-compose.yml上试过
dbreplicasetpart1:
image: mongo:2.6.8
expose:
- '27018'
links:
- replicasetpart2
- replicasetpart3
cap_add:
- NET_ADMIN
dbreplicasetpart2:
image: mongo:2.6.8
links:
- replicasetpart1
- replicasetpart3
expose:
- '27019'
cap_add:
- NET_ADMIN
...我收到一条循环导入消息。但是如果我删除dbreplicasetpart1的反向链接，我就不能从dbreplicasetpart2 ping dbreplicasetpart1。解决方案是什么？

您应该使用大使模式：
https://docs.docker.com/engine/admin/ambassador_pattern_linking/
基本上，您可以创建一个中间组件，将它们连接在一起。您可以看到我们在Spring Cloud的Eureka发现服务中使用的示例：
ambassador:
image: cpuguy83/docker-grand-ambassador
volumes:
- "/var/run/docker.sock:/var/run/docker.sock"
command: "-name eureka_1 -name eureka2_1 "
eureka:
links:
- "ambassador:eureka2"
eureka2:
links:
- "ambassador:eureka"为了简单起见，我只复制了链接

在不更新docker-compose.yml文件的情况下，

我们想办法和大使一起使用这个解决方案。这确实是更舒适的解决方案。适用于我们的配置：
amba1:
image: cpuguy83/docker-grand-ambassador
volumes:
- "/var/run/docker.sock:/var/run/docker.sock"
command: "-name cucumber_dbreplicasetpart1_1"
amba2:
image: cpuguy83/docker-grand-ambassador
volumes:
- "/var/run/docker.sock:/var/run/docker.sock"
command: "-name cucumber_dbreplicasetpart2_1"
amba3:
image: cpuguy83/docker-grand-ambassador
volumes:
- "/var/run/docker.sock:/var/run/docker.sock"
command: "-name cucumber_dbreplicasetpart3_1"
