Fails fast with a clear error and remediation hint if the runner SA lacks configmap delete permission, instead of dying mid-deploy. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

|
# Deploys a stock Headlamp instance with the polaris plugin loaded via
|
|
# a ConfigMap volume mount. No custom Docker images — the plugin is built
|
|
# in CI and injected as a ConfigMap.
|
|
#
|
|
# E2E resources are deployed to the `default` namespace. Nothing persists
|
|
# beyond the test run — teardown cleans up all created resources.
|
|
#
|
|
# Prerequisites:
|
|
# - Plugin built (dist/ exists with plugin-main.js + package.json)
|
|
# - kubectl configured with cluster access
|
|
# - Helm 3 installed
|
|
# - RBAC applied: kubectl apply -f deployment/e2e-ci-runner-rbac.yaml
|
|
#
|
|
# Environment:
|
|
# E2E_NAMESPACE — namespace for E2E Headlamp (default: default)
|
|
# E2E_RELEASE — Helm release name (default: headlamp-e2e)
|
|
# HEADLAMP_VERSION — Headlamp image tag (default: latest)
