From 8edd586dbe6d51afb772f43023a55fa6fd23512a Mon Sep 17 00:00:00 2001 From: Chris Farhood Date: Mon, 4 May 2026 07:25:28 +0000 Subject: [PATCH 1/4] docs: update Headlamp install namespace references from kube-system to headlamp Updates all documentation references to the Headlamp install namespace from kube-system to headlamp as part of PRI-433. In-scope files updated: - README.md, SECURITY.md - docs/getting-started/installation.md, quick-start.md, prerequisites.md - docs/deployment/helm.md, kubernetes.md, production.md - docs/troubleshooting/README.md, common-issues.md, rbac-issues.md - docs/user-guide/configuration.md, rbac-permissions.md - docs/TESTING.md, TROUBLESHOOTING.md, DEPLOYMENT.md Out-of-scope (unchanged): - Source files referencing upstream workload namespace - RBAC manifests describing Polaris namespace (polaris ns is unchanged) - NetworkPolicy namespaceSelector (API server runs in kube-system) - design-decisions.md and ARCHITECTURE.md (URL hashes refer to cluster namespaces, not Headlamp install ns) Co-Authored-By: Paperclip --- README.md | 4 +-- SECURITY.md | 2 +- docs/DEPLOYMENT.md | 4 +-- docs/TESTING.md | 5 ++-- docs/TROUBLESHOOTING.md | 32 ++++++++++---------- docs/deployment/helm.md | 40 ++++++++++++------------- docs/deployment/kubernetes.md | 42 +++++++++++++-------------- docs/deployment/production.md | 30 +++++++++---------- docs/development/testing.md | 5 ++-- docs/getting-started/installation.md | 26 ++++++++--------- docs/getting-started/prerequisites.md | 10 +++---- docs/getting-started/quick-start.md | 10 +++---- docs/troubleshooting/README.md | 10 +++---- docs/troubleshooting/common-issues.md | 32 ++++++++++---------- docs/troubleshooting/rbac-issues.md | 4 +-- docs/user-guide/configuration.md | 2 +- docs/user-guide/rbac-permissions.md | 16 +++++----- 17 files changed, 136 insertions(+), 138 deletions(-) diff --git a/README.md b/README.md index d73104f..7c7c9b2 100644 --- a/README.md +++ b/README.md @@ -97,7 +97,7 @@ metadata: subjects: -
