I have created an pub/sub topic to which I will publish a message every time an new object is uploaded to the bucket. Now I want to create a subscription to push a notification to an endpoint every time a new object is uploaded to that bucket. Following the documentation, I wanted something like that:
gcloud alpha pubsub subscriptions create orderComplete \
--topic projects/PROJECT-ID/topics/TOPIC \
--push-endpoint http://localhost:5000/ENDPOINT/
--ack-deadline=60
However my app is running on kubernetes and it seems that pub/sub cannot reach my endpoint. Any suggestions?
As standing in documentation
In general, the push endpoint must be a publicly accessible HTTPS server, presenting a valid SSL certificate signed by a certificate authority and routable by DNS.
So you must expose your service via HTTPS using Ingress as described there: https://cloud.google.com/kubernetes-engine/docs/concepts/ingress
