running Docker on SL6

gistfile1.md

Docket SL6 で動かすに当たっていろいろ自分で用意しないといけません

• aufs 付きカーネル
• iptables の addrtype
• go
• lxc
• cgroup
• docker

苦労するだけであまり価値が無い

カーネルをビルドできるように丸っと入れる

sudo yum groupinstall 'Development Tools'

aufs のパッチが当たったカーネルをビルド

git clone git://github.com/sfjro/aufs3-linux.git
git checkout aufs3.9
make oldconfig
make menuconfig

いろいろオプション足す

# ccache とか 並列度とかは適当に
make 
sudo make modules_install
sudo make install

go は バイナリを置けば良い

wget http://go.googlecode.com/files/go1.1.1.linux-amd64.tar.gz
tar xvfz go1.1.1.linux-amd64.tar.gz
sudo mv go /usr/local
sudo ln -sv /usr/local/go/bin/go  /usr/local/bin

lxc は RPM としてビルドして入れましょう

wget http://lxc.sourceforge.net/download/lxc/lxc-0.9.0.tar.gz
rpmbuild -ta lxc-0.9.0.tar.gz
sudo rpm -ivh ~/rpmbuild/RPMS/x86_64/lxc-0.9.0-1.el6.x86_64.rpm ~/rpmbuild/RPMS/x86_64/lxc-libs-0.9.0-1.el6.x86_64.rpm

docker のインストール

curl get.docker.io | sudo sh -x
sudo ln -sv /usr/local/bin/docker /usr/bin

ip_foward しないと ホストOS とコンテナ間でパケットが転送されない

sudo sysctl -w net.ipv4.ip_forward=1 

cgroup も マウント ...

sudo mount -t cgroup cgroup /cgroup

いでよ docker !

sudo /usr/bin/docker -d 

enjoy

docker run base /bin/echo hi
