我想在 Docker-Swarm 中将 2 个容器相互连接
I want to connect 2 containers with each other in a Docker-Swarm
我想将两个容器相互连接...我从创建覆盖网络开始 mynet:
docker network create -d overlay mynet
之后，我创建了第一个服务 activemq:
docker service create --name activemq -p 61616:61616 -p 8161:8161 --replicas 1 --network mynet rmohr/activemq
启动并运行良好，我也可以访问 WebUI http://localhost:8161/admin/
现在我要启动我的服务TimeService我在容器中有以下设置：
docker service create --name timeservice -p 7000:7000 --replicas 1 --network mynet ni920/timeserviceplain:latest
java.naming.provider.url=tcp://localhost:61616
java.naming.user=admin
java.naming.password=admin
io.jexxa.rest.host=0.0.0.0
io.jexxa.rest.port=7000
所以它应该通过 tcp://localhost:61616 连接到 ActiveMQ 但它没有。
你们知道我应该尝试什么吗，在 none Swarm 环境或 Kubernetes-Pod 环境中，通信完美无缺？
如果您希望您的容器相互通信 ，您可以使用它们的名称然后让网络驱动程序解析它们的 ips。
这是来自 docker 文档的 network driver summary：
- User-defined bridge networks are best when you need multiple containers to communicate on the same Docker host.
- Host networks are best when the network stack should not be isolated from the Docker host, but you want other aspects of the container to be isolated.
- Overlay networks are best when you need containers running on different Docker hosts to communicate, or when multiple applications work together using swarm services.
- Macvlan networks are best when you are migrating from a VM setup or need your containers to look like physical hosts on your network, each with a unique MAC address.
- Third-party network plugins allow you to integrate Docker with specialized network stacks.
在您的情况下，将 localhost 替换为服务名称 activemq。
java.naming.provider.url=tcp://activemq:61616
