Everything worked fine when I ran it on Docker, but after I migrated it to Kubernetes it stopped connecting to the DB. It says:
pymongo.errors.ServerSelectionTimeoutError
pymongo.errors.ServerSelectionTimeoutError: connection closedwhenever I try to access a page that uses the DB.
I connect like this:
app.config['MONGO_DBNAME'] = 'pymongo_db'
app.config['MONGO_URI'] = 'mongodb://fakeuser:FakePassword@ds1336984.mlab.com:63984/pymongo_db'Any way to get it to connect?
Edit:
I think it has more so to do with the Istio sidecars as when deployed on Kubernetes minus Istio, it runs normally. The issue only appears when running Istio.
Most likely Istio (the Envoy sidecar) is controlling egress traffic. You can check if you have any ServiceEntry and VirtuaService in your cluster for your specific application:
$ kubectl -n <your-namespace> get serviceentry
$ kubectl -n <your-namespace> get virtualserviceIf they exist, check if they are allowing traffic to ds1336984.mlab.com. If they don't exist you will have to create them.
