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 |
| #!/usr/bin/env bash | ||
| set -eo pipefail | ||
| trap 'exit 0' SIGTERM |

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 |
