我正在研究 Canary 部署策略。安装trafik 网格后,我使用服务网格接口。第一次使用命令启动程序时
kubectl apply -f applications.yaml
它应该部署整个应用程序,即 4 个副本,但它只部署了应用程序的 20%(1 个副本),并且它进入了进度状态并出现错误:
TrafficRoutingErro: the server could not find the requested resource (post trafficsplits.splits.smi-spec.io)
TrafficSplitNotCreated: Unable to create traffic Split 'demo-traefficsplit'
这是我的清单:
