Ethernet

When installing Alpine linux, the setup-alpine script should have given you the option to setup ethernet/networking. If you need to setup your networking after installation you can use setup-interfaces script. The script configures wireless and ethernet interfaces in addition to other types and will satisfy most trivial configurations.

setup-interfaces

Start the script by running this command:

# setup-interfaces

Available interfaces are: eth0 wlan0.
Enter '?' for help on bridges, bonding and vlans.
Which one do you want to initialize? (or '?' or 'done') [eth0]

choose eth0 for Ethernet or wlan0 for wireless device, as appropriate.

if asked:

Ip address for eth0? (or 'dhcp', 'none', '?') [dhcp]

choose dhcp

Now it will ask Do you to do any manual network configuration? (y/n) [n]

unless you need to do manual network configuration choose n, if you need to do manual network configuration choose y and it will open the /etc/network/interfaces file.

The above script configures Networking service adds to boot run level and starts the service. Refer Networking service section, if this needs to be done manually.
