Redis connection using from_url #3410
Description
Version: redis version 7.
Platform: python3.11 / redis in-memory instance in GCP
Description: I am trying to make a connection from a python script to an in-memory redis store.
It has an endpoint and is also AUTH and TLS enabled.
`
import redis
import certifi
REDIS_HOST = <primary endpoint>
REDIS_PORT = 6378
REDIS_PASSWORD = <password> # Auth value
REDIS_URL = f'rediss://{REDIS_PASSWORD}@{REDIS_HOST}:{REDIS_PORT}'
'''
redis_client = redis.Redis.from_url(
url=REDIS_URL,
ssl_cert_reqs='required', ssl_certfile = 'server-ca.pem'
)
print(redis_client.ping())
def test_connection():
try:
redis_client.set('test_key', 'test_value')
value = redis_client.get('test_key')
print(f"Successfully connected to Redis.{value}")
except redis.RedisError as e:
print(f"Error connecting to Redis: {e}")
test_connection()
'''
REDIS_URL = f'rediss://{REDIS_PASSWORD}@{REDIS_HOST}:{REDIS_PORT}?decode_responses=True&protocol=3'
url_connection = redis.from_url(REDIS_URL)
url_connection.ping()
`
This is the error I get when I run my script to test the connection. From the code, it can be observed that I tried with SSL option as well, but it fails there too. [commented that portion]. The last few lines that I have is throwing the error that I have shared in the issue right now.
I am not sure how to resolve this issue. really appreciate if some pointers can be shared.
