Databases

We currently support the following databases and they are passed in via the FN_DB_URL environment variable. For example:

docker run -e "FN_DB_URL=postgres://user:pass@localhost:6212/mydb" ...

sqlite3 (default)

URL: sqlite3:///functions/data/functions.db

SQLite3 is an embedded database which stores to disk. If you want to use this, be sure you don't lose the data directory by mounting the directory on your host. eg: docker run -v $PWD/data:/functions/data -e FN_DB_URL=sqlite3:///functions/data/fn.db ...

PostgreSQL

URL: postgres://user123:pass456@ec2-117-21-174-214.compute-1.amazonaws.com:6212/db982398

Use a PostgreSQL database. If you're using Functions in production, you should probably start here.

MySQL

URL: mysql://user123:pass456@tcp(ec2-117-21-174-214.compute-1.amazonaws.com:3306)/funcs
