Yeah in breeze only available simple integration, which need to be run with
`--integration mongo`, e.g.
```console
❯ breeze start-airflow --backend postgres --postgres-version 15
--integration mongo
```
After that you could communicate with Mongo 3 thought the host `mongo`
```python
from airflow import DAG
from airflow.decorators import task
from airflow.providers.mongo.hooks.mongo import MongoHook
with DAG("pr_37214", schedule=None, tags=["37214", "mongodb"]):
@task
def test_mongo():
# Create a connection into the runtime, might be replaced by
connection created into the UI
import os
from airflow.models.connection import Connection
mongo_conn_id = "mongo_test"
conn = Connection(conn_id=mongo_conn_id, conn_type="mongo",
host="mongo", port=27017, schema="test")
os.environ[f"AIRFLOW_CONN_{conn.conn_id.upper()}"] = conn.as_json()
# Actual execution
mongo_hook = MongoHook(mongo_conn_id=mongo_conn_id)
mongo_hook.insert_one("users", {"name": "John", "surname": "Wick"},
mongo_db="test")
collection = mongo_hook.get_collection("users", mongo_db="test")
print(collection.count_documents({}))
test_mongo()
```
And it is expected that if you try to communicate in breeze with `localhost`
or `127.0.0.1` that is not exists, because there is no mongo in Airflow Breeze
