Open Source Cybersecurity Example

README.md

Requirements

• docker
• docker-compose

For ubuntu, use apt install docker.io docker-compose

Running the test

• Place Caddyfile and compose.yaml in the same folder
• Run docker-compose up -d
• Run docker run --rm guacamole/guacamole:1.4.0 /opt/guacamole/bin/initdb.sh --postgres | docker exec -i postgres psql -d guacamole -f -
  • This initializes the guacamole database

Containers

• caddy - web server/reverse proxy with automatic Let's Encrypt Support
• vaultwarden - open source implementation of BitWarden server
• postgres - database for guacamole
• guacd - backend connector for guacamole
• guacamole - web frontend for guacamole
• client - SSH server for guacamole testing
• vncclient - VNC server for guacamole testing

Caddyfile
