Considerations
Some of the key considerations to be taken into account while self-hosting
Networking
Setting up a firewall with UFW
- UFW (or Uncomplicated FireWall) is an easy to use firewall to control which ports are open and to which IPs
- Improves security (since internal ports cannot be exposed, even by mistake)
- Really powerful in controlling who can connect to the server and where they connect to
Basic setup of UFW
- Install UFW:
apt install ufw - Start UFW on boot:
systemctl enable --now ufw - Setup basic rules so you don't get locked out:
- Allow ssh traffic:
ufw allow 22/tcp - Allow web traffic:
- HTTP:
ufw allow 80/tcp - HTTPS:
ufw allow 443/tcp - QUIC/HTTP3:
ufw allow 443/udp
- HTTP:
- Allow ssh traffic:
- Enable UFW:
ufw enable
Migration and backups
Needed for disaster recovery and helps in recovery of data and restoration of state of the system with minimal damage
