| Alpine's package manager is '''apk'''. To update installed packages, run `apk update && apk upgrade`. To add a package like Docker, run `apk update && apk add docker`. The package manager looks to `/etc/apk/repositories` for mirrors. Notably, the community mirror is commented-out by default. Uncomment that line to install software such as [[DockerSetup|Docker]]. === Services === Alpine uses the '''OpenRC''' `init` system, which is designed to be very similar but simpler than the traditional SysV init system. To start a service like Docker, use `service docker start && service docker status`. To set a service like Docker to run at boot, use `rc-update add docker boot`. === Storage === Alpine is a read-only operating system. To make a change persist, the change must actually be committed to the boot overlay files. This is done by running `lbu commit -d`. Persistent storage can be mounted [[FileSystemMounting|through normal processes]]. |

Alpine Linux
Alpine Linux is a Linux-based operating system. It is distinguished from other distributions by its dedication to minimalism. It is ideal for containerized deployments.

Installation
Insert the target device and ensure it is not mounted. (If it is, try umount /dev/sdXN.)
Upstream recommends use of fdisk(8). The partitioning process is as follows:
fdisk /dev/sdX
Ensure that the device is not using a GPT partition table. This would be listed under Disklabel type. (Press p to list the partitions.) The correct value is dos, not gpt.
- Create new partition table with one FAT32 partition
d Delete all partitions (and repeat as needed)
n Create a new partition
p A primary partition
1 Partition number 1
- Use defaults for first and last cylinder (press [Enter] twice).
t Change partition type
c Partition type (Win95 FAT32/LBA)
Ensure that the primary partition is bootable. This is marked by an asterisk (*). (Press p to list the partitions.) To make the partition bootable...
a Set the boot flag on a partition
1 Partition number 1
w Write your changes to the device
For more general advice regarding partitioning, see here.
Format the new partition with:
mkfs.vfat /dev/sdX1
Note that mkfs.vfat and mkdosfs are the same.
Finally, dd(1) the ISO onto the device. Or for a Raspberry Pi, copy the boot binaries onto the device.
