Quick start
Try DVNA using a single command with Docker. This setup uses an SQLite database instead of MySQL.
Access the application at http://127.0.0.1:9090/

Getting Started
DVNA can be deployed in three ways

1. For Developers, using docker-compose with auto-reload on code updates
2. For Security Testers, using the Official image from Docker Hub
3. For Advanced Users, using a fully manual setup

Detailed instructions on setup and requirements are given in the Guide Gitbook

Development Setup
Clone this repository
Create a vars.env with the desired database configuration

MYSQL_USER=dvna
MYSQL_DATABASE=dvna
MYSQL_PASSWORD=passw0rd
MYSQL_RANDOM_ROOT_PASSWORD=yes
