linkerd:忽略自动注入

Question

我已经正确地安装了链接器(链接器检查--代理-n链接器检查都是正常的)。

在那之后，我用"auto-injection"注释了我的covid名称空间

$ kubectl annotate namespace covid linkerd.io/inject=enabled

部署我的部署后：

$ linkerd stat deployments -n covid
NAME                MESHED   SUCCESS   RPS   LATENCY_P50   LATENCY_P95   LATENCY_P99   TCP_CONN
dev-covid-backend      0/1         -     -             -             -             -          -

$ linkerd stat pods -n covid
NAME                                 STATUS   MESHED   SUCCESS   RPS   LATENCY_P50   LATENCY_P95   LATENCY_P99   TCP_CONN
dev-covid-backend-7ccc987d4-494lv   Running      0/1         -     -             -             -             -          -

正如您所看到的，部署不是网状的。

我已经手动触发了心跳。我得到了：

有什么想法吗？

Answer 1

您是否在注释covid命名空间之后重新启动了dev-covid-backend部署？

kubectl rollout restart deploy/dev-covid-backend -n covid

心跳检查与自动注入功能无关。您可以查看proxy-injector日志

kubectl logs -f deploy/linkerd-proxy-injector -n linkerd

以及事件：

kubectl get events -n covid

如果您在那里看到错误或消息，它们应该有助于找到解决方案。
