db name : racktables_db

db user : racktables_user

db password : racktables_password

Usage

Build image and run container.

$ docker build -t racktables .
$ docker run -itd --name racktables racktables

Check the container ip address.

$ docker inspect -f '{{ .NetworkSettings.IPAddress }}' racktables

Access to the racktables and setting up.

http://<IPAddress>/?module=installer

When instructed change the owner on "secret.php", execute the "chsecret.sh".

$ docker attach racktables
docker# /usr/local/share/racktables/chsecret.sh
docker# <Ctrl-p> <Ctrl-q>  # detach container

Enjoy.

it fail whe try to use it with boot2docker.
There are two issues here.

That Dockerfile was doing modifications to kernel parameters at build-time, but those modifications would not carry over to run-time. In other words, the sysctl would be executed during the build, but have no effect on the run.

Those modifications shouldn't even be allowed inside containers (except when they are implemented per-namespace). If you need to tune those parameters, you should do that outside of Docker, or in a privileged container.
