Replace CiliumNetworkPolicies with Istio AuthorizationPolicies, point
the thelounge HTTPRoute at the istio-external gateway, and give each
workload a dedicated ServiceAccount for precise mTLS identity.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
The previous selector matched an Istio-style label that does not exist
on Cilium gateway pods, which caused default-deny ingress and blocked
access to thelounge. Use fromEntities: ingress to match Cilium's own
gateway/ingress pods, consistent with the cluster repo's webhook CNP.
Add CiliumNetworkPolicy ingress rules so thelounge only accepts traffic
from the cilium external gateway in gateway-system, and znc only from
the thelounge pod. Allow host entity on both for kubelet probes.
Switch znc service to ClusterIP and drop the external-dns annotation
since direct external IRC client access is no longer desired.
Drop the istio.io/dataplane-mode label and the AuthorizationPolicies
for thelounge and znc. Gateway was returning upstream connect errors
when traffic transited ztunnel; reverting the namespace to non-mesh
restores reachability. CiliumNetworkPolicies remain for egress filtering.
targetRefs: kind: Service policies require waypoint binding which is not
working in Istio 1.29.2 — WaypointAccepted: False and ztunnel routes
directly to pods bypassing the waypoint. Selector-based policies are
enforced at ztunnel L4 without requiring waypoint.
WaypointAccepted: False on both policies — Istio 1.29 requires
istio.io/use-waypoint on the Service directly, namespace label alone
is insufficient for targetRefs: kind: Service policy binding.
- Add namespace.yaml with istio ambient + waypoint labels
- Add waypoint Gateway (istio-waypoint) scoped to irc namespace
- Switch thelounge HTTPRoute from Cilium external to istio-external gateway
- Add AuthorizationPolicy for thelounge (allow inbound from gateway-system only)
- Add AuthorizationPolicy for znc (allow all on port 6501 for IRC clients)
- Add namespace: irc to root kustomization, remove dependency on targetNamespace

LinuxServer s6-overlay requires starting as root to fix directory
permissions (/run, etc.) before dropping privileges. Setting PUID/PGID
forces immediate UID 1000 start, causing permission errors:
"fatal: /run belongs to uid 0 instead of 1000"
Let the container run as root with existing Polaris exemptions.
The s6-overlay init system handles privilege management internally.
Fixes CrashLoopBackOff in znc-0 pod.

LinuxServer.io containers need to run init scripts with elevated
permissions before dropping to the specified PUID/PGID. Reverted to:
- Remove restrictive securityContext settings
- Use PUID/PGID environment variables (LinuxServer standard)
- Add Polaris exemptions for runAsRoot and runAsPrivileged
- Add Checkov exemption for high UID requirement
This fixes container startup issues introduced by security hardening.

Removed serviceName field from both StatefulSets since stable pod DNS
is not required for single-replica IRC applications. StatefulSets only
need serviceName when using headless Services for stable network identities.
Also removed statefulset-has-servicename ignore since it's now properly fixed.

Add ignores for:
- container-security-context-user-group-id (UID 1000 is standard non-root)
- statefulset-has-servicename (serviceName is correctly set)
- probe-not-identical (ZNC has no HTTP endpoint for different probe types)
These are industry-standard patterns that kube-score flags unnecessarily.

Added comprehensive documentation including:
- Security hardening details (non-root, seccomp, capabilities)
- Architecture overview (StatefulSets, resources, health checks)
- Local development commands (validation, security, best practices)
- Detailed CI/CD pipeline explanation
- Reference to CLAUDE.md for full documentation

- Remove Flux validation job (repo doesn't contain Flux resources)
- Fix trailing spaces in best-practices workflow
- Add missing newline at end of znc/statefulset.yaml
Flux validates Kustomization CRDs, not plain manifests. Since this
repo only contains the manifests deployed by Flux (not the Flux
resources themselves), the validation doesn't apply.

Instead of just skipping security checks, properly fix the issues:
**Pod & Container Security Context:**
- Add runAsUser: 1000 (non-root)
- Add runAsGroup: 1000
- Add fsGroup: 1000 for volume permissions
- Add seccompProfile: RuntimeDefault
- Drop ALL capabilities (principle of least privilege)
**Resource Management:**
- Add ephemeral-storage requests (1Gi) and limits (2Gi)
**Health Checks:**
- Change thelounge liveness probe from TCP to HTTP
- Reduces false positives and provides better health signals
**Reduced Exceptions:**
- Removed 6+ security check exceptions
- Now only skip: image tags (intentional), read-only FS (apps need writes)
- Removed Polaris runAsRootAllowed exemptions
**Note:** If containers fail to start post-merge, may need to adjust UIDs
or add specific capabilities. LinuxServer images may need tweaking.

Updated CLAUDE.md and README.md to clearly document:
- Repository is deployed via Flux CD
- Manifests use Flux variable substitution
- Variables must NOT be replaced with hardcoded values
This prevents future mistakes with variable substitution.

Reverted HTTPRoute hostname to use Flux variable ${THELOUNGE_HOSTNAME}
and updated kubeconform to skip HTTPRoute validation instead.
Flux substitutes variables at deployment time, so the validation
needs to skip resources with variable substitution syntax.
