fix(setup.sh): guard SIGPIPE in site-agent pod lookup (spurious [7h] Code 141)

[kirson-git]

Problem

In the [7h] site-agent verification, the pod lookup is:

_POD="$(kubectl get pods -n nico-rest -l ... -o name 2>/dev/null | head -1)"

The script runs under set -euo pipefail (line 77). head -1 closes the pipe after the first line, kubectl receives SIGPIPE → exit 141, and pipefail propagates it, so the command substitution fails and the phase aborts with SETUP FAILED ... Code: 141 — even though site-agent deployed fine (StatefulSet ready, Site CR HandshakeComplete). Reproduced on a clean v0.10.3 install; same code on main.

Fix

Append || true so the SIGPIPE-induced 141 is tolerated.

  • Improved setup script resilience by enhancing error handling during deployment initialization, preventing script failures when pod selection returns no results and ensuring more reliable setup processes.

Walkthrough

In helm-prereqs/setup.sh, the _POD assignment command within the NICo REST site-agent gRPC connection verification loop is amended by appending || true to the kubectl ... | head -1 pipeline, preventing a non-zero exit code from terminating the script under set -euo pipefail when no matching pods are found.

Changes

NICo REST Site-Agent gRPC Verification Loop

Layer / File(s)	Summary
Guard kubectl pipeline against empty pod list helm-prereqs/setup.sh	|| true is appended to the _POD assignment pipeline so that a zero-result kubectl get pods invocation does not propagate a non-zero exit code and abort the script under set -euo pipefail.
