Getting Started

Follow these steps to set up and start the services:

1. Grant Execute Permissions

Ensure the main.sh script has the necessary permissions:

chmod +x main.sh

2. Generate Environment Files

Create .env configuration files with the following command:

./main.sh generate-env

3. Configure Environment Variables

Edit the generated .env files to fill in the required fields:

• ./gitea/.env
• ./sftpgo/.env
• ./vaultwarden/.env
• ./glance/.env
• ./ghost/.env
• ./immich/.env
• ./uptime_kuma/.env
• ./croc/.env
• ./stalwart/.env
• ./caddy/.env
• ./crowdsec/.env
• ./caddy/Caddyfile.private

4. Bouncer Keys (CrowdSec)

Generate two keys and write them into the matching .env files:

CADDY_KEY=$(openssl rand -hex 32)
FW_KEY=$(openssl rand -hex 32)

# crowdsec/.env
sed -i "s|^CROWDSEC_BOUNCER_KEY_CADDY=.*|CROWDSEC_BOUNCER_KEY_CADDY=$CADDY_KEY|" ./crowdsec/.env
sed -i "s|^CROWDSEC_BOUNCER_KEY_FW=.*|CROWDSEC_BOUNCER_KEY_FW=$FW_KEY|" ./crowdsec/.env

# caddy/.env (same value as CADDY key above)
sed -i "s|^CROWDSEC_API_KEY=.*|CROWDSEC_API_KEY=$CADDY_KEY|" ./caddy/.env

(Optional) get a Console enroll key from https://app.crowdsec.net and put it in CROWDSEC_ENROLL_KEY.

5. Start Services

Launch all services with the following command:

./main.sh start

6. Host Firewall Bouncer (CrowdSec, nftables)

The Caddy bouncer protects HTTP services. Stalwart's mail ports (25/465/587/143/993/110/995/4190) bypass Caddy, so install a firewall bouncer on the host:

sudo apt install crowdsec-firewall-bouncer-nftables

Edit /etc/crowdsec/bouncers/crowdsec-firewall-bouncer.yaml:

mode: nftables
api_url: http://127.0.0.1:18080/
api_key: <value of CROWDSEC_BOUNCER_KEY_FW from crowdsec/.env>
update_frequency: 10s

Enable and start:

sudo systemctl enable --now crowdsec-firewall-bouncer

Verify:

docker exec crowdsec cscli bouncers list      # should show 'caddy' and 'firewall'
docker exec crowdsec cscli decisions list     # current bans
sudo nft list ruleset | grep -A2 crowdsec     # kernel-level rules in place

Allowlist your operator IP at any time:

docker exec crowdsec cscli allowlist create operator -d "Operator IPs"
docker exec crowdsec cscli allowlist add operator <your-public-ip>

Stopping Services

To stop all running services, use:

./main.sh stop
