At the moment, Postiz is entirely configured by environment variables. It is important to understand that any configuration change to environment variables will require an application restart.

An example file of the most used configuration settings can be found here; example postiz.env file

Required Settings

DATABASE_URL

eg: postgresql://postiz-user:postiz-password@localhost:5432/postiz-db-local

Postgres is not strictly necessary, Postiz uses Prisma to connect to the database, so technically mariadb or other databases could be used.

REDIS_URL

eg: redis://localhost:6379

JWT_SECRET

A random string that should be unique for every installation, this is used to secure your JWT auth tokens.

FRONTEND_URL

eg: http://postiz.example.lan:4200

NEXT_PUBLIC_BACKEND_URL

eg: http://postiz.example.lan:3000

BACKEND_INTERNAL_URL

If running everything in the same host/container: http://localhost:3000

Optional settings

Refer to the example postiz.env file for additional configuration options.

OAUTH

See this page for reference.

DISABLE_REGISTRATION

eg: true

This will only allow a single user registration, and then after that the sign-up page will be disabled. Useful for self-hosting where you want complete control over users. Warning: This will disable OIDC / OAuth!

Social Media keys

See the “providers” section of the documentation for the provider you want to configure, for details about how to set that up.
