[INFO]  Loading configuration from config.yml
[INFO]  Loaded configuration: PolynoteConfig(Listen(8192,127.0.0.1),Storage(tmp,notebooks,Map()),List(),List(),Map(),Map(),Behavior(true,Always,List()),Security(None),UI(/))
[WARN]  Polynote allows arbitrary remote code execution, which is necessary for a notebook tool to function.
        While we'll try to improve safety by adding security measures, it will never be completely safe to
        run Polynote on your personal computer. For example:
        
        - It's possible that other websites you visit could use Polynote as an attack vector. Browsing the web
          while running Polynote is unsafe.
        - It's possible that remote attackers could use Polynote as an attack vector. Running Polynote on a
          computer that's accessible from the internet is unsafe.
        - Even running Polynote inside a container doesn't guarantee safety, as there will always be
          privilege escalation and container escape vulnerabilities which an attacker could leverage.
        
        Please be diligent about checking for new releases, as they could contain fixes for critical security
        flaws.
        
        Please be mindful of the security issues that Polynote causes; consult your company's security team
        before running Polynote. You are solely responsible for any breach, loss, or damage caused by running
        this software insecurely.

How do I get Polynote running with Kubernetes?

I'm hoping to run Polynote and in particular against my Kubernetes cluster. Unfortunately I'm not having any luck, the error messages are not particularly helpful, and as far as I can tell it's new enough that there isn't already a reference Kubernetes configuration I can use to make this work.

With the YAML file below I'm getting it to boot up successfully. When I port forward and try to access the pod, though, it crashes the pod, which then restarts and unfortunately the error message I get is literally Killed, which isn't super instructive. I started with the bare Docker image, then added the configuration they suggested in the Docker notes in their repository.
