Configuration File

The configuration file is optional. It’s a text file that follow these rules:

Keys are the same as the environment variables described above.

Example:

DEBUG=on
WORKER_POOL_SIZE=20

Environment variables override the values defined in the config file.

To specify a configuration file, use the command line argument -config-file or -c.

You can also dump interpreted values with the flag -config-dump for debugging.

Systemd uses the file /etc/miniflux.conf to populate environment variables.

Database Connection Parameters

Miniflux uses the Golang library pq to communicate with PostgreSQL. The list of connection parameters are available on this page.

The default value for DATABASE_URL is user=postgres password=postgres dbname=miniflux2 sslmode=disable.

You could also use the URL format postgres://postgres:postgres@localhost/miniflux2?sslmode=disable.

Password that contains special characters like ^ might be rejected since Miniflux 2.0.3. Golang v1.10 is now validating the password and will return this error: net/url: invalid userinfo. To avoid this issue, do not use the URL format for DATABASE_URL or make sure the password is URL encoded.
