You need to be running a 3.8 kernel or above, hence the need for Jessie and the installation of that kernel.
You need to install golang, and specially 1.2 or above else you’ll get ipv6 errors, too. Get it from golang.org
You also need to have lxc and aufs-tools
apt-get install lxc aufs-tools
Then you need to setup your GOPATH environmental variable, create the docker directory in the src directory and clone docker into that.
export GOPATH=/your/go/directory cd $GOPAth mkdir -p src/github.com/dotcloud/ cd src/github.com/dotcloud git clone https://github.com/dotcloud/docker
Then cd into the docker directory to use golang to pull all the dependencies and install docker into your GOPATH’s bin directory
cd docker go get -v github.com/dotcloud/docker/... go install -v github.com/dotcloud/docker/...
(The three dots mean do this for all the packages under said directory)
You should be able to run docker via
Before you can run a docker image you need to mount cgroups. Put this in your /etc/fstab
none /cgroup cgroup defaults 0 0
And then run
mkdir /cgroup && mount -a
You also need to enable ipv4 forwarding else your container won’t be able to talk to the outside world.
sysctl -w net.ipv4.ip_forward=1
Finally you need to run docker as a daemon, and as root, too.
$GOPATH/bin/docker -d & 2013/10/19 23:15:48 WARNING: cgroup mountpoint not found for memory 2013/10/19 23:15:48 Listening for HTTP on /var/run/docker.sock (unix)
Now you can issue a pull request to get the base 120MB ubuntu container from the internet.
$GOPATH/bin/docker pull ubuntu
After it’s downloaded it all, you can now use that container.
$GOPATH/bin/docker run ubuntu echo 'omg'
This should product something like
2013/10/19 23:22:55 POST /v1.6/containers/create 2013/10/19 23:22:55 POST /v1.6/containers/3fe0676d7e00/attach?stderr=1&stdout=1&stream=1 2013/10/19 23:22:55 POST /v1.6/containers/3fe0676d7e00/start omg 2013/10/19 23:22:55 GET /v1.6/containers/3fe0676d7e00/json
First add the squeeze backports to /etc/apt/sources.list:
deb http://backports.debian.org/debian-backports squeeze-backports main
apt-get update apt-get -t squeeze-backports install postgresql-9.1
Then login as the postgres user and start up psql:
su - postgres psql
Now create a new user with a new password and create a database as that user:
create user myuser password 'mypassword' create database mydatabase owner myuser; \q
Now you’ve exited psql, log out of the postgres unix user, and attach the the postgres program remotely:
<ctrl-d> psql -h localhost -U myuser -d mydatabase
Now it’ll ask you to enter in the password ‘myuser’. You can now start issuing sql commands. Or \? to see help for psql commands.
To remove a service, apache2 in this case, from running at all runlevels:
update-rc.d -f apache2 remove
This will remove the apache2 file (located in /etc/init.d/) symlink from all the /etc/rcX.d/ directories.
To simply stop a service:
service apache2 stop
You can replace stop with start to start it.
To use a program compiled for 32 bit, the Android development tools for example, you need the ia32 compatibility package if you’re using 64 bit.
First add i386 to your list of architectures, update apt-get then install ia32
dpkg --add-architecture i386 apt-get update apt-get install ia32-libs
If you need to install a 32 bit version of something, issue the command as normal but with :i386 appended:
apt-get install libncurses5:i386
