我尝试在 IBM Cloud Kubernetes 集群中运行 Prefect 流程。所以我正在设置 Kubernetes 代理。我这样做时看到错误：

kubectl apply -f prefect_agent.yaml

kubectl logs prefect-agent-778f997b7-hnsk2

附加 prefect_agent.yaml

我可以看到创建了角色和角色绑定：

(venv) xxxtorage % kubectl get roles
NAME                 CREATED AT
prefect-agent-rbac   2021-12-07T12:34:57Z

prefect-agent-rbac   Role/prefect-agent-rbac   22m

在运行命令之前，我已将默认命名空间发送到“prefect”。我创建了“prefect”命名空间来组织所有 Prefect 相关的资源。

我发现- name: PREFECT__CLOUD__API_KEY value: {myapikey} 这是由：https ://docs.prefect.io/orchestration/concepts/api.html#authentication

我使用了 Kubernetes 集群 API 密钥。因此错误。
