nice, looks good in general, I noticed a couple of issues when trying this out on a test pod. Let me know if you think this is due to an error with the test pod I used:

apiVersion: v1
kind: Pod
metadata:
  name: clamb-test
spec:
  containers:
  - name: clamb
    image: offchainlabs/nitro-node:v3.0.3-3ecd01e
    command: ["/bin/sh"]
    args:
      - -c
      - |
        #!/usr/bin/env bash
        set -e pipefail
        trap 'exit 0' TERM
        sleep infinity &
        wait $!
  # I used this to check that the signal handling was working
  terminationGracePeriodSeconds: 10

I got the following error when running this on a test pod /bin/sh: 2: set: Illegal option -o pipefail

Suggested change

	set -eo pipefail
	set -e pipefail

I got the following error when running this on a test pod trap: SIGTERM: bad trap seems like some shells expect the signal without the SIG part

Suggested change

	trap 'exit 0' SIGTERM
	trap 'exit 0' TERM
