卸载 osm-edge 网格的故障排查指南

不论何种原因导致的 osm uninstall mesh（如 卸载指南 中所述）失败，可以按照下面的操作手动删除 osm-edge 资源。

为网格设置环境变量：

export osm_namespace=osm-system # Replace osm-system with the namespace where osm-edge is installed
export mesh_name=osm # Replace osm with the osm-edge mesh name
export osm_version=<osm version>
export osm_ca_bundle=<osm ca bundle>

删除 osm-edge 控制平面部署：

kubectl delete deployment -n $osm_namespace osm-bootstrap
kubectl delete deployment -n $osm_namespace osm-controller
kubectl delete deployment -n $osm_namespace osm-injector

如果 osm-edge 与 Prometheus、Grafana 或 Jaeger 一起安装，请删除这些部署：

kubectl delete deployment -n $osm_namespace osm-prometheus
kubectl delete deployment -n $osm_namespace osm-grafana
kubectl delete deployment -n $osm_namespace jaeger

如果 osm-edge 与 osm-edge 多集群网关一起安装，请运行以下命令将其删除：

kubectl delete deployment -n $osm_namespace osm-multicluster-gateway

删除 osm-edge secrets、meshconfig 和 webhook 配置：

警告：确保集群中没有资源依赖于以下资源，然后再继续。

kubectl delete secret -n $osm_namespace $osm_ca_bundle mutating-webhook-cert-secret validating-webhook-cert-secret crd-converter-cert-secret
kubectl delete meshconfig -n $osm_namespace osm-mesh-config
kubectl delete mutatingwebhookconfiguration -l app.kubernetes.io/name=openservicemesh.io,app.kubernetes.io/instance=$mesh_name,app.kubernetes.io/version=$osm_version,app=osm-injector
kubectl delete validatingwebhookconfiguration -l app.kubernetes.io/name=openservicemesh.io,app.kubernetes.io/instance=mesh_name,app.kubernetes.io/version=$osm_version,app=osm-controller

要从集群中删除 osm-edge 和 SMI CRD，请运行以下命令。

警告：删除 CRD 将导致与该 CRD 对应的所有自定义资源也被删除。

kubectl delete crd meshconfigs.config.openservicemesh.io
kubectl delete crd multiclusterservices.config.openservicemesh.io
kubectl delete crd egresses.policy.openservicemesh.io
kubectl delete crd ingressbackends.policy.openservicemesh.io
kubectl delete crd httproutegroups.specs.smi-spec.io
kubectl delete crd tcproutes.specs.smi-spec.io
kubectl delete crd traffictargets.access.smi-spec.io
kubectl delete crd trafficsplits.split.smi-spec.io
