TIPS

• Only use rootless container runtime (podman, rootless docker)
• Allow non-root ports < 1024 via echo "net.ipv4.ip_unprivileged_port_start=53" > /etc/sysctl.d/ports.conf
• Use a reverse proxy like Traefik, Nginx to terminate TLS with a valid certificate
• Use Let’s Encrypt certificates to protect your SSL endpoints
