[sqlalchemy] Re: Airflow > Configuring A SQL Alchemy Connection String To Use Unix Sockets

2017-11-10 Thread james . lloyd
Found it!

I wasn't using the $AIRFLOW_HOME environment variable (I didn't think it 
relied on it).

As such 
airflow initdb
Must've been using it's own ariflow.cfg file.Not the one in /airflow.

[sqlalchemy] Airflow > Configuring A SQL Alchemy Connection String To Use Unix Sockets

2017-11-09 Thread james . lloyd
Hello.

I'm using the SQL Cloud Proxy on a Compute engine VM instance. I'm then 
configuring Airflow (which uses SQL Alchemy).

I've setup a unix socket like this:

/opt/cloud_sql_proxy/cloud_sql_proxy 
-instances=myproject:europe-west1:airflowinstance -dir=/cloudsql &


I can connect to the Cloud SQL Proxy using this socket without any trouble. 
i.e.,

mysql -u airflowuser -p -S /cloudsql/myproject:europe-west1:airflowinstance

But I can't get Airflow to connect using the below connection string:

sql_alchemy_conn = mysql://airflowuser:xxx@/airflowdatabase?unix_socket=
/cloudsql/myproject:europe-west1:airflowinstance

I get a 'connection refused' error.

Any help much appreciated!
