gcloud - BrokerCell cloud-run-events/default is not ready

I am trying to use google cloud for my pubsub event driven application. Currently, I am setting up Cloud Run for Anthos following the below tutorials

I have created the GKE clusters. It is successful and is up and running.

However, I am getting the below error when I try to create event broker.

$ gcloud beta events brokers create default --namespace default

ERROR: gcloud crashed (TransportError): HTTPSConnectionPool(host='oauth2.googleapis.com', port=443): Max retries exceeded with url: /token (Caused by SSLError(SSLError("bad handshake: Error([('SSL routines', 'tls_process_server_certificate', 'certificate verify failed')])")))

gcloud's default CA certificates failed to verify your connection, which can happen if you are behind a proxy or firewall.
To use a custom CA certificates file, please run the following command:
  gcloud config set core/custom_ca_certs_file /path/to/ca_certs

However, When I rerun the command, it shows broker already exists

$ gcloud beta events brokers create default --namespace default

ERROR: (gcloud.beta.events.brokers.create) Broker [default] already exists.

Checking the status of broker, it shows BrokerCellNotReady

$ kubectl get broker -n default

NAME     URL                                                        AGE   READY     REASON

default  http://default-brokercell-ingress.cloud-run-events.svc.cluster.local/default/default   39m   Unknown   BrokerCellNotReady

And I am getting status pending for default-brokercell-fanout pod.

$ kubectl get pods -n cloud-run-events

I couldn't find any discussion related to this error. Please give me some ideas to resolve this issue.

Solution

  • I encountered the same issue. The reason might be the given cluster setup does not have enough CPU resources.

    You can check it by

    kubectl describe pod/default-brokercell-retry-6f4f9696d6-tg898 -n cloud-run-events

    If the output is enter image description here then that's the reason.

    After knowing the root cause, you can fix it in various ways, e.g., enable auto-scaling in your node pool.
