#Docker OpenStack Swift onlyone
Simple deployment of a "all in one" style OpenStack Swift server, uses Ubuntu packages as opposed to source.
There is a makefile with some useful helper commands, as well as a swiftrc file that you can use as well which shorts the swift command as well as adds a function to set a container to be a public, listable html page.
I suggest using the data container methodology.
So first we create a data only container for /srv.
vagrant@host1:~$ docker run -v /srv --name SWIFT_DATA busyboxNow that we have a data container, we can use the "--volumes-from" option when creating the "onlyone" container. Note that in this case I've called the image built from this docker file "curtis/swift-onlyone".
vagrant@host1:~$ ID=$(docker run --name onlyone --hostname onlyone -d -p 12345:8080 --volumes-from SWIFT_DATA -t curtis/swift-onlyone)With that container running we can now check the logs.
vagrant@host1:~$ docker logs $ID

swift.txtThat's it!
- It seems supervisord running as root in the container, a better way to do this?
- bash command to start rsyslog is still running...
- Add all the files in /etc/swift with one ADD command?
- supervisor pid file is getting setup in /etc/
