I have the docker image deployed to a heroku, but I am stuck on getting the server app connected to mysql and redis. I am running
fleet prepare db
but the error
failed to start: creating db connection: default addr for network '<http://us-cdbr-east-05.cleadb.net/asdfasdfasdf|us-cdbr-east-05.cleadb.net/asdfasdfasdf>' unknown
. It seems to not know the URL for that db, but that’s the url provided by heroku in their server env variables.

How are you setting the fleet mysql address? Can you paste the value you are using (make sure you replace any sensitive info like username and password)?

Hi! Yes, I have an env variable set to:
FLEET_MYSQL_ADDRESS: <mysql://xxx:xxx@us-cdbr-east-05.cleardb.net/heroku_e825c9bd49d3cbb?reconnect=true>
7:04 PM
and that
mysql://
address is given by the cleardb mysql heroku add-on.
7:05 PM
I basically made the configuration in heroku env variables to match here.
7:05 PM
I am assuming that the only one that I have to get right here is the MYSQL_ADDRESS. The other ones I can specify however I want and
fleet prepare db
will do the rest?

Ah, I see the problem. Fleet expects the database configuration to be provided via multiple environment variables
FLEET_MYSQL_ADDRESS
,
FLEET_MYSQL_DATABASE
,
FLEET_MYSQL_USERNAME
,
FLEET_MYSQL_PASSWORD
. See https://fleetdm.com/docs/deploying/configuration#my-sql

I did set all of these:
FLEET_MYSQL_ADDRESS
,
FLEET_MYSQL_DATABASE
,
FLEET_MYSQL_USERNAME
,
FLEET_MYSQL_PASSWORD
. But are you saying that they need to be specific strings that match the set up of the db?

you were trying to pass everything in via
FLEET_MYSQL_ADDRESS
. In this case, you need to do
FLEET_MYSQL_ADDRESS=<http://us-cdbr-east-05.cleardb.net:3306|us-cdbr-east-05.cleardb.net:3306>
FLEET_MYSQL_DATABASE=heroku_e825c9bd49d3cbb
FLEET_MYSQL_USERNAME=xxx
FLEET_MYSQL_PASSWORD=xxx

7:19 PM
but at least it’s a new issue, so that’s progress!
7:20 PM
by the way, how did you know to use port 3306? Is that some kind of standard convention?

3306 is the default mysql port
