I have a python app that needs to connect to mongodb statefulset in kubernetes I made a chart for my app and mongodb as a dependency using helm. when the data needs to be written to the DB it send this error code:
pymongo.errors.OperationFailure: Authentication failed., full error: {'operationTime': Timestamp(1629805756, 1), 'ok': 0.0, 'errmsg': 'Authentication failed.', 'code': 18, 'codeName': 'AuthenticationFailed', '$clusterTime': {'clusterTime': Timestamp(1629805756, 1), 'signature': {'hash': b'\xde\x1e\t\x93:H\xd1\x9b\x9b\x15\xacu@S\xe9\x02\xd6#`\xae', 'keyId': 6999961677823213573}}}The python configs for mongo:
from flask import Flask,request,render_template,jsonify
from pymongo import MongoClient
import os
from dotenv import load_dotenv, find_dotenv
load_dotenv(find_dotenv())
MONGODB_URI = os.getenv('MONGODB_URI')
app = Flask(__name__)
client = MongoClient(MONGODB_URI)
db = client.calocalcdb
collection = db.calocalc_collection
users = db.usersThe mongo URI is in a secret file and the application should get it via env variable. the program fails on this line:
user_id = users.insert_one(user)When i try to echo $MONGODB_URI from the application pod it returns nothing.
In your depoyment yaml you need something to map the secret to the environment variable; something like:
spec:
template:
spec:
containers:
env:
- name: MONGODB_URI
valueFrom:
secretKeyRef:
name: <secret name>
key: <secret name>
