The controller limits the Ingress and apisix.apache.org/v2 resources it syncs to the namespaces matching namespace_selector. Surface it as config.namespaceSelector so it can be set through the chart. The field is rendered only when it holds entries, so the default keeps selecting every namespace.

Do not expose namespaceSelector with controller 2.2.1.
The 2.2.1 controller does not define or consume namespace_selector. A non-empty value can therefore be ignored, so repeated-key OR behavior never applies. Remove this chart option until the controller image supports it, then regenerate the Values table.
Suggested fix
- # -- Label selectors of the namespaces whose Ingress and apisix.apache.org/v2 resources are
- # synced. A namespace is selected when its labels match all entries, and the values given for
- # the same key are ORed, so `["team=a", "team=b", "env=prod"]` selects the namespaces labeled
- # `team in (a,b)` that are also labeled `env=prod`. Empty selects all namespaces.

What this PR does
api7-ingress-controller supports
namespace_selector, which limits the Ingress andapisix.apache.org/v2resources it syncs to the namespaces whose labels match (api7/api7-ingress-controller#487). The chart had no value for it, so it could only be set by editing the rendered ConfigMap.This adds
config.namespaceSelector:Every entry must match and the values given for the same key are ORed, so the example selects the namespaces labeled
team in (a,b)that are also labeledenv=prod. Each entry accepts the full Kubernetes label selector syntax.The block is rendered only when the list is non-empty, so the default behavior (all namespaces) is unchanged for existing releases.
Chart version 0.1.28 -> 0.1.29. README regenerated with helm-docs.
