New Features
-
Support for customization workloadSelector of sidecar #33 #35
Priority: workloadSelector.labels > workloadSelector.fromService
1.when
serviceFence.spec.workloadSelector.fromService: true, sidecar.spec.workloadSelector.Labels = svc.spec.selector
2.Otherwise, sidecar.spec.workloadSelector.Labels will equalenv.Config.Global.Service: serviceFence.Name, which is compatible with old version lazyload. -
Support for disable ServiceFence auto generating #36
In previous version, namespace and service level ServiceFence auto generating is auto enable. Now we can disable them through new fields in fence config, like below. Default value is false.
{ "general": { "wormholePort": [ "9090" ], "disableAutoFence": true }, "name": "lazyload" }
Engineering Enhancement
-
Make dynamic service dependency info durable #37
When lazyload starting, it will generate cache contains dynamic service dependency info from existed ServiceFences, which contains useful info in
status.metricStatus. After this change, it will never cause dynamic relationships lost when lazyload pod restarting or deleting. -
Complete fence module config migration #39
-
Support prometheus as lazyload metric source in istio 1.12+ #42
In istio 1.12+, the way of metadata_exchange filters insertion is changed, related pr Add metadata exchange as native code. So global-sidecar will be inserted these filters.
Then prometheus metric, what we want is like
service A -> service B, will beservice A -> global-sidecarandglobal-sidecar -> service B. Lazyload cannot get right relationships anymore in previous version with prometheus metric mode.In this pr, we remove metadata_exchange filters from global-sidecar via the envoyfilter named
global-sidecar-metadata-exchange-remove, and this problem is solved.
