未能安装带舵机的instana代理

Question

kubectl get ns提供了以下名称空间

communication-prod   Active   69d
custom-metrics       Active   164d
default              Active   218d
kube-node-lease      Active   218d
kube-public          Active   218d
kube-system          Active   218d
notification         Active   191d
notification-stock   Active   118d

但是，当我运行以下helm命令时

helm install instana-agent \
  --repo https://agents.instana.io/helm \
  --namespace instana-agent \
  --create-namespace \
  --set agent.key=foo\
  --set agent.downloadKey=bar \
  --set agent.endpointHost=ingress-green-saas.instana.io \
  --set agent.endpointPort=443 \
  --set cluster.name='communication-engine-prod' \
  --set zone.name='asia-south1' \
  instana-agent

我收到以下错误

Error: INSTALLATION FAILED: rendered manifests contain a resource that already 
exists. Unable to continue with install: ClusterRole "instana-agent" in namespace "" 
exists and cannot be imported into the current release: invalid ownership metadata; label 
validation error: missing key "app.kubernetes.io/managed-by": must be set to "Helm"; 
annotation validation error: missing key "meta.helm.sh/release-name": must be set to
"instana-agent"; annotation validation error: missing key "meta.helm.sh/release-namespace": must be set to "instana-agent"

有人能告诉我为什么我会犯这个错误吗？

这看起来就像您使用kubectl安装了代理，然后在尝试helm之前删除了名称空间。您需要删除第一次安装尝试中创建的所有资源。最简单的方法是这样做：

kubectl delete -f configuration.yaml

使用用于安装代理的相同配置文件(如果不修改Instana仪表板，也可以从Instana仪表板生成一个新的配置文件)。您还可以使用kubectl get clusterroles和kubectl get clusterrolebindings获取需要用kubectl delete删除的实体。
