To configure a static IP address on Alpine Linux, you will need to perform the following steps:
/etc/network/interfaces, and add the following lines, replacing <interface> with the name of your network interface and <static IP address>, <netmask>, and <default gateway> with the appropriate values for your network:auto <interface>
iface <interface> inet static
address <static IP address>
netmask <netmask>
gateway <default gateway>
Save the changes to the configuration file and exit the text editor.
Restart the network service to apply the changes:
systemctl restart networking
ip command:ip addr show <interface>
Alternatively, you can use the ifconfig command to view the network configuration:
ifconfig <interface>
