title: How to SSH to docker container in kubernetes cluster?
body: <p>I am fairly new to the Google Cloud platform and Docker and set-up a cluster of nodes, made a Dockerfile that copies a repo and runs a Clojure REPL on a public port. I can connect to it from my IDE and play around with my code, awesome!</p>
  
  <p>That REPL should however probably tunneled through SSH, but here is where my problem starts. <strong>I can't find a suitable place to SSH into</strong> for making changes to the repo that Docker runs the REPL on:</p>
  
  <ul>
  <li>The exposed IP just exposes the REPL service (correct kubernetes term?) and does not allow me to SSH in. </li>
  <li>Neither does the cluster master endpoint, it gives me a public key error even though I've followed the <code>Adding or removing SSH keys for all of the instances in your project</code> part <a href="https://cloud.google.com/compute/docs/instances/adding-removing-ssh-keys" rel="noreferrer">here</a>.</li>
  </ul>
  
  <p>I would like to edit the source files via SSH but I would need to access the docker code repo. I don't know how to proceed.</p>
  
  <p>I understand this isn't exactly a typical way to deploy applications so I am not even sure it's possible to have multiple nodes work with a modified docker codebase (do the nodes share the JVM somehow?).</p>
  
  <p>Concretely my question is how do I SSH into the docker container to access the codebase?</p>
