SvenDowideit:

Alpine makes a great docker container, because it is so small and optimized to be run in RAM.
It might also might make a good controller for several docker containers with enough RAM. I haven't tested this yet
Docker's setup is easy to use from command line. Commands can be run from an interactive shell, or through a configuration file called a "Dockerfile".
docker.com has excellent walk-throughs on how to run, pull, setup a container, commit an image, and create a configuration file. hub.docker.com is a freemium setup, where the first private repository is free.

== To install from Alpine ==

'''apk add docker'''

To start the Docker daemon at boot, run:

'''rc-update add docker boot'''

then to start the Docker daemon manually, run:

'''service docker start'''

The Docker package is in the 'Community' repository, so if the '''apk add''' fails with '''unsatisfiable constraints''', you need to edit the '''/etc/apk/repositories''' file to add a line like:

http://dl-6.alpinelinux.org/alpine/edge/community

== Example: How to install docker from Arch ==

https://wiki.archlinux.org/index.php/Docker

== '''How to use docker''' ==

The best documentation for how to use Docker and create containers is at the main docker site. Adding anything more to it here would be redundant.

'''http://docs.docker.com/'''

if you create an account at docker.com you can browse through other user's images and learn from the syntax in contributor's dockerfiles.

Official Docker image files are denoted by a blue ribon on the website.

Create a Bootable Device

2016-01-03T06:18:57Z

SvenDowideit: /* = Alpine Linux from 3.3.0 and later */

== Creating a bootable Alpine Linux USB Stick from the command line ==

This process applies to Alpine Linux 1.9.0 or later, and results in a '''run-from-ram''' style installation.

{{Warning|This process can potentially totally or partly erase the contents of your hard drive. For this reason, it is recommended to do this procedure using VirtualBox rather than your own computer.}}

=== Requirements ===
In order to follow this document, you will need:
* Alpine Linux CD-ROM ([[Downloads|Download]] a .iso file containing an Alpine release.)
* A USB drive (flash, external HD, card reader, etc.)

=== Alpine Linux from 3.3.0 and later ===

From Alpine Linux 3.3.0, the generated ISO's are a hybridISO, which means they contain a valid MBR and can be raw copied directly to the USB stick, Hard Drive (If you really know what you're doing), or burnt to a CD/DVD.

If the USB stick is in a Unix/Linux/OSX system, you will need to find out what the USB device is (I use '''fdisk -l'''), and then you can use '''dd''' to copy the iso to it:
dd if=alpine.iso of=/dev/sdx

{{:Include:Copying Alpine to Flash|USB stick}}
=== Slow USB Devices ===
Specifying the 'waitusb=X' option at the end of the syslinux.cfg line might help with certain USB devices that take a bit longer to register. X stands for the amount of seconds kernel will wait before looking for the installation media.
append initrd=/boot/grsec.gz alpine_dev=usbdisk:vfat modules=loop,cramfs,sd-mod,usb-storage quiet '''waitusb=3'''
