Part of the org-wide Headlamp namespace migration (PRI-340). Updates the default E2E_NAMESPACE in deploy and teardown scripts to match the new headlamp-dev namespace. The shared workflow (e2e.yaml) already passes headlamp-dev via the e2e-namespace input. Co-Authored-By: Paperclip <noreply@paperclip.ing>

# Deploys a stock Headlamp instance with the sealed-secrets 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 `headlamp-dev` 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
|
||
# RBAC is managed via Flux from privilegedescalation/infra/base/rbac/e2e-ci-runner-headlamp-rbac.yaml.
|
||
# The infra repo is the source of truth — do not apply this file directly.
|
||
# Apply RBAC first: kubectl apply -f privilegedescalation/infra/base/rbac/e2e-ci-runner-headlamp-rbac.yaml
|
||
#
|
||
# Environment:
|
||
# E2E_NAMESPACE — namespace for E2E Headlamp (default: headlamp-dev)
|
||
# E2E_RELEASE — release/resource name prefix (default: headlamp-e2e)
|
||
# HEADLAMP_VERSION — Headlamp image tag (default: latest)
