When I connect using pymongo in localhost, this works:
mongodb://mongo-service:27017
But fails with this error when running on Kubernetes:
ERROR:src.app:Exception on /api/polls [GET] Traceback (most recent call last): File "/.venv/lib/python3.10/site-packages/flask/app.py", line 2077, in wsgi_app response = self.full_dispatch_request() File "/.venv/lib/python3.10/site-packages/flask/app.py", line 1525, in full_dispatch_request rv = self.handle_user_exception(e) File "/.venv/lib/python3.10/site-packages/flask/app.py", line 1523, in full_dispatch_request rv = self.dispatch_request() File "/.venv/lib/python3.10/site-packages/flask/app.py", line 1509, in dispatch_request return self.ensure_sync(self.view_functions[rule.endpoint])(**req.view_args) File "/home/appuser/src/app.py", line 28, in get_all polls = list(repository.get_all_polls()) File "/home/appuser/src/repository.py", line 11, in get_all_polls return _get_collection().find() File "/home/appuser/src/repository.py", line 28, in _get_collection return mongo.get_collection(DATABASE, COLLECTION) File "/home/appuser/src/mongo.py", line 15, in get_collection return MongoClient(connection_string).get_database(database).get_collection(collection) File "/.venv/lib/python3.10/site-packages/pymongo/mongo_client.py", line 704, in __init__ res = uri_parser.parse_uri( File "/.venv/lib/python3.10/site-packages/pymongo/uri_parser.py", line 568, in parse_uri nodes = split_hosts(hosts, default_port=default_port) File "/.venv/lib/python3.10/site-packages/pymongo/uri_parser.py", line 376, in split_hosts nodes.append(parse_host(entity, port)) File "/.venv/lib/python3.10/site-packages/pymongo/uri_parser.py", line 137, in parse_host raise ValueError("Port must be an integer between 0 and 65535: %s" % (port,)) ValueError: Port must be an integer between 0 and 65535: 27017
To make it work I had to add a slash at the end, which shouldn't be required as per the connection string specification.
mongodb://mongo-service:27017/
