  4. Choose a hostname.
  5. When prompted for which interface you want to initialize, choose eth0.
  6. Choose dhcp.
  7. If you don't use IPv6, choose no for manual network configuration. If you use IPv6, enter yes for manual configuration and append the following to the file:

    iface eth0 inet6 static
        address <your assigned IPv6 address>/64
    
  8. Choose a password for the root user.

  9. Choose a timezone.

Wait for the server to reboot.

4. Upgrade the System

  1. Login as root with the password you set earlier.
  2. Type apk update to update the repositories
  3. Type apk upgrade to upgrade the system's packages

5. Create a New User

Because logging in as root is not recommended, you should create a new user for daily tasks.

  1. Type adduser <username> to create a user.
  2. Type adduser <username> wheel to add the user to the wheel group.
  3. Type apk add doas to install doas which is a privilege escalation tool like sudo.
  4. Allow members of the wheel group to use doas:

    echo "permit nopass :wheel" > /etc/doas.conf
    
  5. Type passwd -l root to lock the root account as it is no longer used.

Conclusion

Alpine Linux is now installed and running on your server. See the official Alpine Linux wiki for more information on what you can do next.
