All the users have different targets.. for many Linux and/or Unix-like users most common are the actual work of developing your application to respond appropriately in each environment, you may also face issues with tracking down dependencies, scaling your application, and updating individual components without affecting the entire system.

For all of this a proper setup of your system are need, but if you deploy all of that ecosystems in your own home and works.. in your only machine... you will need a proper guide to setup your main system (or maybe a parallel system?.

The following information will assist you with the installation of Alpine Linux.

in a variety of ways.. as main OS in your disk.. as alternate system, as read-only in a usbstick or maybe none of them! You will said: what? that's is possible? o hell yeah with Alpine all it's possible


Installation Quick-Start in 3 Easy Steps

1st

Download one of the latest stable-release ISOs. Then compare the image's checksum to the one in the corresponding checksum file (*.sha256) and verify its GPG signature.


2nd

If you have a CD drive from which you can boot, then burn the ISO onto a blank CD using your favorite CD burning software. Else create a bootable USB drive.


3rd

Boot from the CD or USB drive, login as root with no password, and voilà! Enjoy Alpine Linux!


One of the first commands you might want to use is setup-alpine.

Installation Handbook

Basics

Alpine can be used in any of three modes:

diskless mode
You'll boot from a read-only medium such as the installation CD, a USB drive, or a Compact Flash card.
Tip: To prepare either a USB or Compact Flash card, you can use the setup-bootable script; see the pages linked above for details.
When you use Alpine in this mode, you need to use Alpine Local Backup (lbu) to save your modifications between reboots. That requires some writable medium, usually removable. If your boot medium is, for example, a USB drive, you can save modifications there; you don't need a separate partition or drive. See also Local APK cache.
Note: When the setup-alpine script asks for a disk, say "none". It will then prompt whether you'd like to preserve modifications on any writable medium.

data mode

As in diskless mode, your OS is run from a read-only medium. However, here a writable partition (usually on a hard disk) is used to store the data in /var. That partition is accessed directly, rather than copied into a tmpfs; so this is better-suited to uses where large amounts of data need to be preserved between reboots.
Note: The setup-alpine script handles installing Alpine in this mode, too, when you supply a writable partition instead of "none", and request mode "data".
This mode may be used for mailspools, database and log servers, and so on.

sys mode

This is a traditional hard-disk install (see link for details). Both the boot system and your modifications are written to the hard disk in a standard Linux hierarchy.
Note: The setup-alpine script handles installing Alpine in this mode, too, when you supply a writable partition instead of "none", and request mode "sys". By default, it will create three partions on your disk for /boot, /, and swap; however you can also partition your disk manually.
This mode may be used for desktops, development boxes, and virtual servers.
