s2aio¶

s2aio is a script that installs Swift (with Keystone) and Storlets all on one. The script allows to do the installation either on the host where it is invoked or in a Docker container.

To install on the host:

Make sure to have a user that can sudo without a password. With that user just do:

sudo apt-get update
sudo apt-get install python-tox python-nose git
git clone https://github.com/openstack/storlets.git
cd storlets
./s2aio.sh install dev host

To install in a Docker container follow the same steps, replacing the last command with:

./s2aio.sh install dev docker

If you do not have Docker installed on your host, the above script will install it and set docker to use “vfs” as the docker storage driver (instead of the default “aufs” storage driver). If you already have Docker installed, you may need to change its storage driver to “vfs”. The created Docker container runs yet another container. Running Docker in Docker may require the usage of the “vfs” storage device.

When installed on the host, the script can be used to start and stop all relevant services using:

./s2aio.sh stop

and

./s2aio.sh start

For the Swift data, the s2aio installation uses a loopback device over a .img file. When shutting down the host, the .img file may get corrupted. Thus, the above stop and start commands are useful when using s2aio.sh for in a long lived hosts that can get rebooted from time to time.
