Short Description
Ubuntu base image
Full Description
Ubuntu base image generator
Run sudo sh buildubu.sh
to generate a Ubuntu base image.
It will use debootstrap
, create a tar-file, generate the Dockerfile
and add a SHA256 checksum of the created tar-file to a ENV
in the Dockerfile
.buildubu.sh
will also add .git
and any previously generated tar-files
to .dockerignore
.
The generated Ubuntu wily
image will weigh in around 105M compared to the Docker hub library
version which is around 133M.
Build and verify
sudo sh buildubu.sh <release> <mirror>
For example:
$ sudo sh buildubu.sh trusty http://se.archive.ubuntu.com/ubuntu/
$ docker build -t ubuntu -f Dockerfile .
$ docker run -t -i ubuntu bash
