# Scale the whole chart down without uninstalling it: scaleDown: true renders # every Deployment/StatefulSet with replicas: 0 (and suspends CronJobs) and # takes precedence over any per-workload replicas value.

Off by default, so # an existing release is unaffected; exactly one of ingress.enabled and # httpRoute.enabled may be true. # # The chart renders ONLY an HTTPRoute with parentRefs - no Gateway, no # gatewayClassName, no Certificate and no implementation-specific policy # object. Class and certificate belong to the Gateway and therefore to the # platform, which is what keeps this chart independent of whether the cluster # runs nginx-gateway-fabric, Cilium, Envoy Gateway or Istio. # # The Gateway-API CRDs must be installed in the cluster: the chart does not and # cannot detect them (.Capabilities.APIVersions is unreliable at template # time), so with httpRoute.enabled: true and no CRDs the INSTALL fails. httpRoute: enabled: false # The Gateway(s) this route attaches to - a platform object, usually in # another namespace, which must allow this namespace in its listener's # allowedRoutes.

Set # explicitly only to publish under a different or an additional name - which # is how a migration from the Ingress runs: the HTTPRoute takes a second # hostname while the Ingress keeps ingress.domain. hostnames: [] # --------------------------------------------------------------------------- # NetworkPolicy (Gitea #5). On by default. The reference implementation with # the full reasoning is template-chart; the convention is in README, "Chart # style guidelines", and the operator's view on this chart's wiki page. # --------------------------------------------------------------------------- networkPolicy: # WHAT THIS POLICY ALLOWS: inbound 8080 only - the single port this pod # declares - and outbound nothing but DNS. CyberChef is a static web app # whose recipes run in the browser, so the pod has no reason to open an # outbound connection at all, which makes the egress cap unusually tight. # # WHAT IT DOES NOT DO: the 8080 rule is NOT restricted by source in the # default, because 8080 is the port all three probes address - see # probeSources below. So this policy is a port and egress ceiling, not # pod-level isolation. And it is only a boundary where the CNI enforces # policies; unenforced, it is accepted and filters nothing. enabled: true # Namespaces whose pods may reach this workload, in addition to the release's # own namespace, which is always allowed. Empty means: own namespace only. # # Matched on the "kubernetes.io/metadata.name" label Kubernetes sets on every # namespace itself, so no labelling work is needed on a namespace this chart # does not own - and no typo protection either: a name that does not exist # matches nothing and is silently ineffective. Note the granularity: an entry # opens the port to EVERY pod in that namespace. allowedNamespaces: [] # Source CIDRs allowed to reach port 8080, which is the port all three probes address. # # EMPTY MEANS OPEN, NOT BLOCKED. With no entry that rule is rendered WITHOUT a # "from" selector, so the port is reachable from anywhere the CNI routes to - # inside the cluster, since it carries no NodePort. # # That is the deliberate choice between two bad defaults. The kubelet's probes # originate from the IP of the WORKER NODE running the pod, an address this # chart cannot know and must not guess: a CIDR that excludes the real node # blocks every probe, the pod never becomes Ready, the rollout times out, and # the symptom reads as a broken application rather than as a policy. # # Narrow it by listing the worker node IPs (e.g. ["10.0.1.11/32"]) - and mind # the companion trap: once this list is non-empty the rule IS restricted, so # everything else that needs the port has to be in it. The chart adds the own # namespace, the ingressController below and allowedNamespaces to the same rule for exactly that reason. probeSources: [] # The ingress controller allowed to reach the routed port once probeSources # restricts it. Rendered only while ingress.enabled or httpRoute.enabled is true, and only in # the restricted branch - with the default (open) rule the controller reaches # the port anyway. The two keys become ONE "from" entry and are therefore an # AND: pods carrying podLabels IN namespace. That is the point of having them # at all - the controller's namespace in allowedNamespaces would open the port # to every pod in kube-system. # # MEASURED ON THIS CLUSTER, NOT ASSUMED (2026-10-14): ingress-nginx is gone, # the only IngressClass is "traefik" and it is the default, and the controller # is the DaemonSet rke2-traefik in kube-system. The same Traefik serves the # Gateway API here, so this one source covers the Ingress and the HTTPRoute # path alike. A policy written against the wrong controller is accepted, looks # strict, and silently blocks all web traffic - and ingress.className says # nothing about it, because a class names an implementation, not the pods the # traffic comes from. ingressController: namespace: kube-system podLabels: app.kubernetes.io/name: rke2-traefik egress: # Additional outbound TCP ports. DNS (UDP and TCP 53) is always allowed and # has no switch - a knob whose only other setting breaks every name lookup # in the pod is a trap, not a feature. # # PORTS, NOT DESTINATIONS, and that is a limit of the object rather than # laziness: a NetworkPolicy matches CIDRs and selectors and never hostnames, # so "only to the database host" cannot be written at all. Each entry # permits its port to ANY destination. What the cap still buys is real: a # compromised pod cannot open arbitrary outbound connections. # # Nothing is needed here for CyberChef itself. Add 443 only if something # is put in front of the pod that has to call out. extraPorts: []
