Kubernetes configuration to link containers

I am trying to see if there are any example to create a Kubernetes POD
which starts 2-3 containers and these containers are linked with each other but couldn’t find any.

Does anybody tried linking containers using Kubernetes config.

  • Docker fails to start container occasionally with error “lstat /dev/dm-1: no such file or directory”
  • Error adding a node to docker swarm
  • Mac host doesn't like Docker container port forwarding
  • Docker Mac Beta and container connecting to host ports?
  • Error initialising MongoDB replica set in Docker container
  • Why docker stops already running containers during startup?
  • Docker best practice on base images and host os
  • Get image id from image created via remote API
  • Docker container can't connect to host application using IP whitelist
  • service docker start fails (daemon is not a docker command)
  • Docker - Application source code updates
  • OpenVSwitch in container with IP-Tables

    The containers in same pod shares the localhost, so you need not link containers, just use localhost:containerPort.

    You have to use the Kubernetes service (Proxy) https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/services.md#how-do-they-work.

    Have a look how they work togehter: https://github.com/GoogleCloudPlatform/kubernetes/tree/master/examples/guestbook

    To be specific, there is no concept of “linking” similarly to the way Docker does it. Every service endpoint is a fully qualified domain name and you just call it from one container to another, and every label on a container that can be picked up by a service endpoint can be used to direct network traffic. So, you don’t have to do ENV[“$FOO_BAR_BAZ”] to get the correct IP, just call it directly (curl http://foo_bar_baz).

    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
