kubernetes – Google Cloud Composer 2 environment is not normal

kubernetes – Google Cloud Composer 2 environment is not normal

 


I'm trying to create a Google Cloud Composer 2 environment in my project, but it's not working.

Created with default settings and a service account with the Cloud Composer v2 API Service Agent Extension, Composer Worker, and Editor roles. The environment starts, some pods are created, but eventually it doesn't become healthy with the error “Some of his GKE pods failed to become healthy”. Check the GKE logs for details and retry the operation. From the logs, it looks like there is an issue with Kubernetes.

Traceback (most recent call last): File “/opt/python3.11/lib/python3.11/threading.py”, line 1045, _bootstrap_inner self.run() File “/opt/python3.11/lib/ python3 .11/threading.py”, line 982, run self._target(*self._args, **self._kwargs) file “/opt/python3.11/lib/python3.11/sched.py”, 151 Line 36, run action(*argument, **kwargs) in file “/home/airflow/src/composer_monitoring/lib/event_scheduler.py”, line 36, repeat action(*action_args) in file “/home/airflow/src/composer_monitoring /lib/composer_metric.py”, line 140, value of update_recent_metric_values ​​= self.calculate_metric_values() kubernetes.client.Exceptions.ApiException: (404)

This is still part of the environment creation and the DAG has not been uploaded yet. Other potentially relevant logs logged during the creation process:

[conn-id:69bde5bac9fb7084 rpc-id:72f13b85e6957114 remote-addr:10.60.0.204:57830 pod:composer-system/airflow-monitoring-7b76fb5846-q7gnw] “/computeMetadata/v1/universe/universe_domain” HTTP/404: generic::not_found: Child “universe_domain” is missing, reason: “NOT_FOUND”, UserMessage: “Not Found”, on 2024-05-16 10:53:13.799086669 It has started. +0000 UTC m=+1558.116947164 HTTP response body: {“kind”:”Status”,”apiVersion”:”v1″,”metadata”:{},”status”:”Failure”,”message”:”horizo​ ​ntalpodautoscalers.Autoscaling \”airflow-worker-hpa\” not found”,”reason”:”NotFound”,”details”:{“name”:”airflow-worker-hpa”,”group “:”autoscaling”,”kind” :”horizontalpodautoscalers”},”code”:404} Resource 'projects/xxx/global/instanceTemplates/gk3-europe-west3-xxx-scheduli-pool-2-1c38f934' was not found

This project is fairly new and has very few custom settings. Added a firewall rule to allow all egresses. We also granted all service accounts created by Cloud Composer 2 the permissions specified in the documentation.

I tried this process several times, each time giving more permissive settings to the service account and firewall, but without success.
