<div>Alpine makes a great docker container, because it is so small and optimized to be run in RAM.<br />
It might also might make a good controller for several docker containers with enough RAM. I haven't tested this yet<br />
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". <br />
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.<br />
<br />
== To install from Alpine ==<br />
<br />
'''apk add docker'''<br />
<br />
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 (or uncomment) a line like:<br />
<br />
'''http://dl-6.alpinelinux.org/alpine/edge/community'''<br />
<br />
<br />
To start the Docker daemon at boot, run:<br />
<br />
'''rc-update add docker boot'''<br />
<br />
<!--<br />
you'll need to disable some kernel security flags:<br />
'''<br />
sysctl -w kernel.grsecurity.chroot_caps=0<br />
sysctl -w kernel.grsecurity.chroot_deny_chmod=0<br />
sysctl -w kernel.grsecurity.chroot_deny_chroot=0<br />
sysctl -w kernel.grsecurity.chroot_deny_mknod=0<br />
sysctl -w kernel.grsecurity.chroot_deny_mount=0<br />
'''<br />
--><br />
<br />
then to start the Docker daemon manually, run:<br />
<br />
'''service docker start'''<br />
<br />
<br />
== Example: How to install docker from Arch ==<br />
<br />
https://wiki.archlinux.org/index.php/Docker<br />
<br />
<br />
== '''How to use docker''' ==<br />
<br />
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.<br />
<br />
'''http://docs.docker.com/'''<br />
<br />
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.<br />
<br />
Official Docker image files are denoted by a blue ribon on the website.</div>Binduwavellhttps://wiki.alpinelinux.org/w/index.php?title=Docker&diff=12509Docker2016-03-13T21:19:24Z<p>Binduwavell: Re ordered stuff, added doc on sysctl flags that may be needed based on comment from IRC. However since I have not been able to validate these flags, I've commented them out for now.</p>
