Connecting to Cloud SQL postgres instance with SSL in python

I am trying to connect to a postgres instance I have in cloud sql. I have everything set up and am able to connect to it if ssl encryption is turned off. But now that I have it on I am trying to connect but running into some error.
def run():
connector = Connector()
def getconn():
conn = connector.connect(
os.getenv("CONNECTION_NAME"),
"pg8000",
user = os.getenv('DB_USERNAME'),
password = os.getenv("DB_PASSWORD"),
db=os.getenv('DB_NAME'),
ip_type= IPTypes.PRIVATE
)
return conn
pool = sqlalchemy.create_engine(
"postgresql+pg8000://",
creator=getconn,
pool.execute("CREATE TABLE........;")
All the certs are stored in secret manager as strings so I am using env variables to grab them, which is why I used cadata for example. But running into this error cadata does not contain a certificate why is this error coming up?

I'd recommend using the Cloud SQL Python Connector to connect to Cloud SQL from Python as it will generate the SSL context for you, meaning no need to manage SSL certificates! It also has additional benefits of not needing to authorize networks etc.
You can find a code sample for the Python Connector similar to the one you are using for establishing a TCP connection.
There is also an interactive getting started Colab Notebook that will walk you through using the Python Connector without you needing to change a single line of code!
It makes connecting to Cloud SQL both easy and secure.

Connecting to SQL Server with Python SQLAlchemy impersonating a specific windows account

I am trying to connect to a SQL Server instance using SQLAlchemy through Python, however I require the SQL connection to come from a specific Windows AD account that isn't the one I run VSCode with. Is there any way to modify the connection string below to explicitly feed SQL Server a Windows login that isn't the same login I am using the run VSCode?
(I am able to connect with this connection string if I "Run as a different User" in VSCode, however the AD accounts with SQL access does not have shared drive access and therefore cannot access shared files, so this won't scale long-term)
import urllib
from sqlalchemy import create_engine
params = urllib.parse.quote_plus('DRIVER={SQL Server};SERVER={server};DATABASE={database};Trusted_Connection=Yes')
engine = create_engine(f'mssql+pyodbc:///?odbc_connect={params}')

Accessing an Azure Database for MySQL Single Server from outside Azure

Moving this question from DevOps Stack Exchange where it got only 5 views in 2 days:
I would like to query an Azure Database for MySQL Single Server.
I normally interact with this database using a universal database tool (dBeaver) installed onto an Azure VM. Now I would like to interact with this database using Python from outside Azure. Ultimately I would like to write an API (FastAPI) allowing multiple users to connect to the database.
I ran a simple test from a Jupyter notebook, using SQLAlchemy as my ORM and specifying the pem certificate as a connection argument:
import pandas as pd
from sqlalchemy import create_engine
cnx = create_engine('mysql://XXX', connect_args={"ssl": {"ssl_ca": "mycertificate.pem"}})
I then tried reading data from a specific table (e.g. mytable):
df = pd.read_sql('SELECT * FROM mytable', cnx)
Alas I ran into the following error:
'Client with IP address 'XX.XX.XXX.XXX' is not allowed to connect to
this MySQL server'.
According to my colleagues, a way to fix this issue would be to whitelist my IP address.
While this may be an option for a couple of users with static IP addresses I am not sure whether it is a valid solution in the long run.
Is there a better way to access an Azure Database for MySQL Single Server from outside Azure?

As mentioned in comments, you need to whitelist the IP address ranges(s) in the Azure portal for your MySQL database resource. This is a well accepted and secure approach.

Cannot connect AS400 by python

I am using idb_bm module to build the connection to the AS400 by using the following code.
from ibm_db import connect
connection = connect('DATABASE=DATABASE;'
'HOSTNAME=xxx.xxx.xxx.xxx;'
'PORT=446;'
'PROTOCOL=TCPIP;'
'UID=uid;'
'PWD=pwd;', '', '')
After execute the code, it shows the following error,
connection = connect('DATABASE=DATABASE;'
SQLCODE=-30061][CLI Driver] SQL30061N The database alias or database name "DATABASE " was not found at the remote node. SQLSTATE=08004
The AS400 structure is complicated with tons of library and tons of table in each library. What's the database alias or database name actually? I have stuck to it for few days....Thanks all.

Assuming you actually have a modern POWER server running IBM i and not a 20 year old AS/400...
Download IBM Access Client Solutions (ACS)..
Set up a connection to your IBM i.
The "Schemas" component of ACS will show you a list of databases on the server.

Assuming you're connecting to the local database and not an iASP, you should be able to use *LOCAL.

Trying to Connect to azure cosmos client using python, Gives 104 connection aborted error

Okay so I have an azure cosmos subscription, where I have created a Mongo DB resource, Now when I am using python SDK to connect it, now it's given when 104, error, connection reset by peer.
Now I am not sure what's the issue,
I am using endpoint with SSL True and Primary Key.
code
endpoint = "http://XXX.mongo.cosmos.azure.com:10255/?ssl=true"
key = 'xxxxxxxxxxxxxxxx'
# <create_cosmos_client>
client = CosmosClient(endpoint, key)

When choosing the MongoDB API, you must use a native MongoDB SDK (in your case, pymongo); the wire protocol is MongoDB, and operations are performed via the same protocol as MongoDB.
Your code is attempting to use the Cosmos DB SDK, which is specific to, and will only work with, the Core (SQL) API.
If you look in the portal blade for your MongoDB-API instance, you'll see examples under Quick Start tab, which each use a MongoDB SDK in its examples (or the mongo shell). Same thing with the Connection Strings tab, showing native MongoDB connection strings (as well as the separate parts of the connection string).
