Installation

Oftp4Net runs as a Docker image for linux/amd64 and linux/arm64 and stores its data in PostgreSQL.

Save the following file as compose.yaml and change the passwords and the host name.
Start it with docker compose up -d. The database schema and a self-signed TLS certificate are created on the first start.
Open http://localhost:8080, sign in as admin / admin and set a new password.
Create your identity, import certificates, add a listener on port 6619 and your partners. The README describes every step.
