Ben's notes

From: http://goodsquishy.com/2014/01/playing-with-docker-on-fedora-20/

yum install docker-io
systemctl start docker
systemctl enable docker

• Build a root file system for the container

  yum --installroot=/root/bbroot --releasever=20 install busybox

• Remove cached data

  cd /root/bbroot/
  rm -rf ./var/cache/yum/* ./var/lib/yum/yumdb/* ./var/lib/yum/history/* ./var/log/yum.log

• Build symlinks to busybox for the utilities it provides

  mkdir bin
  for linkname in $(./sbin/busybox --list) ; do ln -s /sbin/busybox bin/$linkname ; done

• Import it into docker as a new image

  tar -czf - . | docker import - busybox:v1

And your done, you can now start your new container with the docker run command

docker images
docker run -t -i --name busybox busybox:v1 /bin/sh

docker pull fedora
docker images
docker run -t -i fedora:20 /bin/bash 

yum --installroot=/root/fedroot --releasever=20 install yum fedora-release coreutils
cd /root/fedroot/
rm -rf ./var/cache/yum/* ./var/lib/yum/yumdb/* ./var/lib/yum/history/* ./var/log/yum.log
tar -czf - . | docker import - myfedora:v1
docker run -t -i myfedora:v1 /bin/sh

docker rmi $(docker images | grep "^<none>" | awk "{print $3}") 

docker ps -a
docker start 344db3753522

#or by name
docker start busybox

docker attach busybox

yum install bridge-utils -y
