当我在Airflow版本1.10中使用 KubernetesPodOperator 运行docker映像时
When I run a docker image using KubernetesPodOperator in Airflow version 1.10
一旦Pod成功完成任务,气流就会尝试通过k8s流客户端与Pod建立连接来获取xcom值.
Once the pod finishes the task successfullly, airflow tries to get the xcom value by making a connection to the pod via k8s stream client.
以下是我遇到的错误:
[2018-12-18 05:29:02,209] {{models.py:1760}} ERROR - (0) Reason: Handshake status 403 Forbidden Traceback (most recent call last): File "/usr/local/lib/python3.6/site-packages/kubernetes/stream/ws_client.py", line 249, in websocket_call client = WSClient(configuration, get_websocket_url(url), headers) File "/usr/local/lib/python3.6/site-packages/kubernetes/stream/ws_client.py", line 72, in __init__ self.sock.connect(url, header=header) File "/usr/local/lib/python3.6/site-packages/websocket/_core.py", line 223, in connect self.handshake_response = handshake(self.sock, *addrs, **options) File "/usr/local/lib/python3.6/site-packages/websocket/_handshake.py", line 79, in handshake status, resp = _get_resp_headers(sock) File "/usr/local/lib/python3.6/site-packages/websocket/_handshake.py", line 152, in _get_resp_headers raise WebSocketBadStatusException("Handshake status %d %s", status, status_message) websocket._exceptions.WebSocketBadStatusException: Handshake status 403 Forbidden
我正在为此使用K8s服务帐户
I'm using K8s service account for this
DAG配置
xcom = true,
xcom=true,
get_logs = True,
get_logs=True,
in_cluster = true
in_cluster=true
推荐答案
所以我们也遇到了这个问题,我们不得不修改rbac规则,特别是必须添加动词"create"的资源"pods/exec" "和获取"
So we also hit this problem, we had to modify our rbac rules, in particular we had to add the resource "pods/exec" with the verbs "create" and "get"
--- kind: ClusterRole apiVersion: rbac.authorization.k8s.io/v1 metadata: name: airflow-runner rules: - apiGroups: [""] resources: ["deployments", "pods", "pods/log", "pods/exec", "persistentvolumeclaims"] verbs: ["*"] - apiGroups: [""] resources: ["secrets"] resourceNames: ["singleuser-image-credentials"] verbs: ["read","list","watch","create","get"]更多推荐
