我已经使用stable/airflow舵图在Kubernetes上部署了一个Airflow实例。我对puckel/docker-airflow映像进行了少许修改，以能够安装Kubernetes执行器。现在，所有任务都已在Kubernetes集群上成功执行，但是找不到这些任务的日志。
我想将日志上传到我们的Azure Blob存储帐户。我已经这样配置了环境变量：
AIRFLOW__CORE__REMOTE_BASE_LOG_FOLDER="wasb-airflow"
AIRFLOW__CORE__REMOTE_LOG_CONN_ID="wasb_default"
AIRFLOW__CORE__REMOTE_LOGGING="True"
wasb_default连接包括Azure Blob存储帐户的登录名和密码。我已经使用WasbHook测试了此连接，并成功删除了一个虚拟文件。
当我尝试查看日志时，显示以下消息：
*** Log file does not exist: /usr/local/airflow/logs/example_python_operator/print_the_context/2019-11-29T15:42:25+00:00/1.log

关于如何解决此问题的任何想法？
