It’s a quick and easy option and works well for most use cases I’ve come across. The most reliable solution I’ve come across so far is to alias to the loopback 0 interface: sudo ifconfig lo0 alias $CONTAINER_IP

Add the container IP to the lo0 interface.

Although this produces the expected results it’s not an optimal solution, given the possibility of constantly changing IP addresses, or of no connection at all. Connecting from a container to the hostĪttempting to connect to the host’s en0 interface address was the first breakthrough we had. In summary, this means it’s pretty much impossible to directly reach a container via its internal address, while containers cannot access services on the host. The VM uses VPNKit for exposing container ports to localhost, but the network settings and adapters are not configurable, meaning that containers cannot be accessed via their IPs and there is no network interface which bridges between the physical machine and the virtual machine. The problemĭocker for Mac uses Hyperkit to run a xhyve VM for the Docker daemon.

It wasn’t the first time I had experienced service-container communication issues and a huge hint was of course the fact that this seemed to work seamlessly on Linux.Īfter many headaches, investigation, trial and error here are a few solutions I’ve gathered and tested that could be of help to you too. Producers and consumers could be started easily from within the containers and communicate between themselves at that level.Īs soon as I attempted to establish a connection between the local UPS instance and the Kafka broker, however, all communication seemed to come to a standstill.Īlthough the application could connect to the broker on its published port and the topics were being created, the messages sent from the UPS were not being properly published and the consumer wasn’t reading anything back. The most straightforward and uncomplicated solution was running the UPS locally, while Zookeeper and the Kafka broker would run in two separate Docker containers.įrom the very beginning I ran into loads of issues.
