chore: upgrade api7 and gateway to v3.10.6 - #355
Conversation
Version bumps for the 3.10.6 release: appVersion and the image tags on both charts, and each chart's own per-line version counter. Also exposes apisix.streamPlugins on the gateway chart. 3.10.6 adds four L4 Prometheus metrics, two of which are backed by a shared memory zone that apisix init only renders into nginx.conf when prometheus is in stream_plugins. That list is not in the chart and config-default.yaml ships it commented out, so the metrics could not be turned on from the chart at all - enableCustomizedConfig replaces the whole config.yaml and discards every templated value, which is not a usable path for adding one list. The value is empty by default and renders nothing when unset, so an existing release keeps the image default unchanged. Nothing else needed syncing: the Control Plane helm/ directory is unchanged between v3.10.5 and v3.10.6, and the only new gateway config key, nginx_config.stream.metrics_zone_size, is left to the image default of 1m, which the upstream comment records as covering any realistic number of stream listening addresses.

- Around line 195-201: Remove the streamPlugins value from the chart values, its
config.yaml template rendering, and its README documentation entry. Ensure the
gateway chart no longer exposes or statically writes the Control Plane-owned
stream_plugins list; stream plugin enablement must remain managed through the
Control Plane configuration path.

The local pre-commit hook runs helm-docs v1.14.2, which appends an Autogenerated footer to charts without a README.md.gotmpl. CI runs a version that does not, and every committed README is in that form, so the footer made the helm-docs check fail on charts/api7/README.md.
AGENTS.md is explicit that the gateway chart must not expose the enabled plugins / stream_plugins list, because the Control Plane owns it through the etcd /plugins key. Adding it here was the wrong layer, so the PR goes back to a pure version bump. The gap that motivated it is real but belongs to the gateway: the apisix_stream_metrics_zone directive is gated on yaml_conf.stream_plugins in apisix/cli/ops.lua, which apisix init reads from config.yaml before etcd is consulted, so the Control Plane's own plugin list can never enable it. A Kubernetes deployment therefore cannot export apisix_stream_active_connections or apisix_stream_bandwidth. Fixing that means changing what the directive is gated on, not what the chart renders.

conf/config-default.yamlgained one key,nginx_config.stream.metrics_zone_size, plus a comment block onapisix.trusted_addresses. The key is deliberately not chart-exposed: it sizes the stream metrics shared memory zone, one slot per stream listening address, and the upstream comment records the1mdefault as covering any realistic number of them. Both the chart and the Docker Compose package fall back to the same image default, so the two deployment forms do not diverge.Verification
The rendered ConfigMap's
config.yamlwas extracted and run throughapisix initinapi7/api7-ee-3-gateway:3.10.6, with default values and withgateway.stream.enabled=trueplus a stream TCP port. Both render a config the image accepts, and the chart renders nostream_pluginsin either case — the Control Plane owns that list, per AGENTS.md.3.10.6 adds four L4 Prometheus metrics, two of which read a shared memory zone. That zone was originally gated on
stream_pluginsin the Data Plane's own configuration file, which the chart cannot set, so a Kubernetes deployment could not export them; api7/api7-ee-3-gateway#2151 tracked it and #2152 fixed it inside this release by rendering the zone whenever the stream subsystem runs. Retested against the rebuilt image: with the chart's own rendered config and nostream_pluginsanywhere, the directive is present once the stream proxy is enabled, and proxied TCP sessions export all four metrics.
