Sentry: How to use redis with password

[iv-mexx]

Somehow I can not get sentry to work when using a password for redis.

Without redis password set it works without problem.

However, when I set a password for redis (By this I mean I set a password on the redis server and then I configure the same password in sentry.conf.py)

The according block in sentry.conf.py looks almost like in the setup guide:

SENTRY_REDIS_OPTIONS = {
    'hosts': {
        0: {
            'host': '127.0.0.1',
            'port': 6379,
            'password': 'mypassword'
        }
    }
}

When trying to start sentry celery worker it prints this error message:

[2016-02-08 18:28:07,421: ERROR/MainProcess] consumer: Cannot connect to redis://localhost:6379//: .
Trying again in 2.00 seconds...

and stack traces like this:

[ERROR] Unable to record event:
Event was: u'consumer: Cannot connect to redis://localhost:6379//: .\nTrying again in 2.00 seconds...\n'

at every connection attempt.

When I intentionally set a wrong password in sentry.conf.py, I get an exception
sentry.exceptions.InvalidConfiguration: NOAUTH Authentication required. as expected.

I'm not sure if I'm missing some configuration or if this is an error in sentry :question:
Sentry Version is 8.1.2

I dont have a lot of experience with redis.

As mentioned, the Error-Message is

[2016-02-08 18:30:51,150: ERROR/MainProcess] consumer: Cannot connect to redis://localhost:6379//: .
Trying again in 26.00 seconds...

Shouldn't the URL contain the redis password, something like: redis://:password@hostname:port?

Hey @iv-mexx, so the error that you pointed out is coming from the connection for the queue. That comes from BROKER_URL. So in your case, you'd need to use the format you pointed out there. Also documented here: http://docs.celeryproject.org/en/latest/getting-started/brokers/redis.html#configuration

Thanks for the quick help @mattrobenolt, its now working! :+1:

[mattrobenolt]

I updated our docs too to clarify this since it was slightly counter intuitive imo. Thanks for pointing it out.

If someone stumbles upon this thread: the password for Redis can be set using the environment variable SENTRY_REDIS_PASSWORD
