我正在使用 https://github.com/helm/charts/tree/master/stable/airflow掌舵图并puckle/docker-airflow
使用安装的Kubernetes构建v1.10.8 图像并在掌舵图中使用该图像,但是我一直在获取

obj, end = self.scan_once(s, idx)
json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 1 column 2 (char 1)
在我的调度程序中,正如各种消息来源所建议的那样,我尝试设置:
AIRFLOW__KUBERNETES__KUBE_CLIENT_REQUEST_ARGS: {"_request_timeout" : [60,60] }
以我的掌舵价值观 那也没有用的人有什么想法我想念什么?
这是我的价值观
airflow:
image:
repository: airflow-docker-local
tag: 1.10.8
executor: Kubernetes
service:
type: LoadBalancer
config:
AIRFLOW__KUBERNETES__WORKER_CONTAINER_REPOSITORY: airflow-docker-local
AIRFLOW__KUBERNETES__WORKER_CONTAINER_TAG: 1.10.8
AIRFLOW__KUBERNETES__WORKER_CONTAINER_IMAGE_PULL_POLICY: Never
AIRFLOW__KUBERNETES__WORKER_SERVICE_ACCOUNT_NAME: airflow
AIRFLOW__KUBERNETES__DAGS_VOLUME_CLAIM: airflow
AIRFLOW__KUBERNETES__NAMESPACE: airflow
AIRFLOW__KUBERNETES__KUBE_CLIENT_REQUEST_ARGS: {"_request_timeout" : [60,60] }
AIRFLOW__CORE__SQL_ALCHEMY_CONN: postgresql+psycopg2://postgres:airflow@airflow-postgresql:5432/airflow
persistence:
enabled: true
existingClaim: ''
workers:
enabled: false
postgresql:
enabled: true
redis:
enabled: false
编辑:
在我添加之后,尝试在helm values.yaml中设置环境变量的各种尝试均不起作用(请注意双引号和单引号)
ENV AIRFLOW__KUBERNETES__KUBE_CLIENT_REQUEST_ARGS='{"_request_timeout" : [60,60] }'
到Dockerfile的位置:https : //github.com/puckel/docker-airflow/blob/1.10.9/Dockerfile#L19
之后,我的airflow-scheduler
Pod启动,但是随后我的调度程序Pod上一直出现以下错误。
Process KubernetesJobWatcher-9: Traceback (most recent call last):
File "/usr/local/lib/python3.7/site-packages/urllib3/contrib/pyopenssl.py", line 313,

同样的问题在这里:-(

docker-airflow:1.10.8
,并取出改变L931的config/airflow.cfg
对kube_client_request_args =
,并使用该图片。似乎工作
