Docker

docker is a tool that makes linux containers super easy.

slackware package

There is a build available on slackbuilds. The only build dependency is golang

slackware container

I have published an image on the the public docker index called vbatts/slackware. Once you have docker installed, and the daemon started:

sudo sh /etc/rc.d/rc.docker start

then to access this image, just run:

docker run -i -t vbatts/slackware bash

Use cases

I've made a build script that enables building a slackware image from other versions of Slackware. You can get that source on github.com/vbatts/slackware-docker.

Since the container state is basically ephemeral, it makes for a great build environment, since it's like starting fresh every time.

Once you have a base image, can install a full version of slackware like so:


# copy a mirror if you haven't already
rsync -avPHS rsync://slackware.osuosl.org/slackware/slackware64-14.1/ ./slackware64-14.1/

# run the container
# privileged mode is required
# and mounting in the local mirror (read-only)
docker run -i -t --privileged -v $(pwd)/slackware64-14.1/:/mnt/slackware64-14.1/:ro  vbatts/slackware /sbin/upgradepkg --install-new /mnt/slackware64-14.1/slackware64/*/*.t?z /mnt/slackware64-14.1/patches/packages/*.t?z

# save that ephemeral container as a reusable image
docker commit $(docker ps -l -q) $USER/slackware-full

Now you can use this full install for package build/validation


# build an SBo in an clean slate
git clone git://slackbuilds.org/slackbuilds.git
# make a directory for the built artifact to wind up in
mkdir sbo-tmp
# mount in the needed directories, and run the steps needed to build
docker run -i -t -v $(pwd)/sbo-tmp:/tmp -v $(pwd)/slackbuilds:/mnt -w /mnt/development/google-go-lang $USER/slackware-full bash
 
New York-- to that tall skyline I come
Flyin' in from London to your door
New York-- lookin' down on Central Park
Where they say you should not wander after dark.
New York.
