SafeLine is a free and open-source Web Application Firewall (WAF) designed to protect web apps against modern attacks without requiring coding.
The .env file in SafeLine's installation directory contains crucial configuration variables like directory paths, passwords, and Docker image details.
Variables in the .env file manage settings such as data storage, Docker image version, web management port, database and Redis passwords, subnet prefix, and image registry path.
Users can customize SafeLine settings by editing the .env file, enabling flexibility in managing ports, security credentials, networking, and image sources.
