Dockerfiles for assorted [Ubuntu][]-based Docker images.

Dockerfiles are sorted into directories with names matching their function. To avoid duplication all images extend base which defines the maintainer and contains updated packages. The Makefile script builds each tag with:

$ docker build -t $image_name .

for example:

$ docker build -t smartmontools .

The dependency graph is:

base  (ubuntu,amd64)
`-- smartmontools  (disks monitoring)

Run:

$ make

to build all images.
