Docker Pairing Environment

This repo includes a Dockerfile and Kubernetes StatefulSet to set up a pod that can be used as a shared pairing environment. To use it, follow the following steps:

1. Build the Dockerfile with docker build -t some/tag .

2. Edit statefulset.yaml to use image tag you specified when building the image (TODO: can we publish a shared image to kubernetes-dev?)

   • NOTE: you may also have to edit the storageClassName for the volumeClaimTemplate to match a valid storage class where you are running the image. For example, to run this on a local k3s cluster you would need to change it to be local-disk.

3. Run kubectl apply -f statefulset.yaml

4. Run k exec -it -n grafana-dev pair-box-0 -- /bin/bash in order to set up a few things in the box:

   • Run passwd pair to setup a password for the pair account

   • Copy your public ssh key into /home/pair/.ssh/authorized_keys

5. Put the following in your SSH config (~/.ssh/config)

   Host pair-box
       ProxyCommand kubectl --kubeconfig=$HOME/.kube/config exec -i pods/pair-box-0 -- /usr/sbin/sshd -i
       HostName pair-box
       User pair
       ServerAliveInterval 300
       ServerAliveCountMax 2
