Docker on Debian Wheezy

gistfile1.txt

Enabled “wheezy main” and “wheezy-updates main” in
/etc/apt/sources.list, commented out the CD.

From http://backports.debian.org/Instructions/

    # echo 'deb http://ftp.debian.org/debian/ wheezy-backports main' > /etc/apt/sources.list.d/backports.list

    # apt-get update
    # apt-get install lxc iptables bridge-utils libdevmapper-dev golang git mercurial gcc libsqlite3-dev

To get a more recent kernel (>3.8 recommended by Docker):

    # apt-get install -t wheezy-backports linux-image-amd64 linux-headers-amd64
    # CONFIG=/boot/config-3.11.0.bpo.2-amd64 lxc-checkconfig

Install Go v1.1+:

    # mkdir ~/src
    # cd ~/src
    # wget http://go.googlecode.com/files/go1.2.linux-amd64.tar.gz
    # tar -C /usr/local -xvf go1.2.linux-amd64.tar.gz
    # cat <<EOF >> /etc/profile.d/go.sh
    > export GOROOT="/usr/local/go"
    > export GOPATH="/usr/local/lib/go"
    > FIRST_PATH=$(echo "\${PATH}" | sed 's/:.*//')
    > if [ "\${FIRST_PATH}" != "\${GOROOT}/bin" ]; then
    >   export PATH="\${GOROOT}/bin:\${GOPATH}/bin:\${PATH}"
    > fi
    > EOF

(use `su -` to make sure you get /etc/profile sourced)

Install Docker:

    # mkdir -p $GOPATH/src/github.com/dotcloud
    # cd $GOPATH/src/github.com/dotcloud
    # git clone https://github.com/dotcloud/docker.git
    # cd docker
    # git checkout v0.7.1
    # go get -v github.com/dotcloud/docker/...

Run it:

    # docker -d

Network goes down…  Move bridge so it doesn't conflict with the VPN:

    # ip addr del 172.17.42.1/16 dev docker0
    # ip addr add 172.31.42.1/16 dev docker0

Then:

    # docker -d
