=======
|
|
|
|
A small base image designed for use in containers. The image
|
|
is based on glibc for wide compatibility, and has apt for
|
|
access to a large number of packages. The image is based
|
|
on Debian, with some things that aren't required in containers
|
|
removed:
|
|
|
|
* Some packages that aren't often used in containers
|
|
(hardware related, init systems etc.)
|
|
* Some files that aren't usually required (docs, man pages,
|
|
locales, caches)
|
|
|
|
This image aims to strike a good balance between having
|
|
small images, and having many quality packages available
|
|
for easy integration.
|
|
|
|
These images also include an `install_packages` command
|
|
that you can use instead of apt. This does two things:
|
|
|
|
1. Install the named packages, skipping prompts etc.
|
|
2. Clean up the apt metadata afterwards to keep the image small.
|
|
|
|
e.g.
|
|
|
|
$ install_packages apache2 memcached
|
|
|
|
Compatibility
|
|
-------------
|
|
|
|
The image points to the Debian archive, so you are free to
|
|
install packages from there that you need. However because
|
|
some `Essential` packages have been removed they may not
|
|
always install or work correctly.
|
|
|
|
In those cases you can figure out which package is needed
|
|
and manually specify to install it along with your desired
|
|
packages.
|
|
|
|
Docker
|
|
------
|
|
|
|
You can use the image directly, e.g.
|
|
|
|
$ docker run --rm -it minideb:latest
|
|
|
|
There are tags for the different Debian releases.
|
|
|
|
$ docker run --rm -it minideb:jessie
|
|
|
|
The images are built daily and have the security release enabled,
|
|
so will contain any security updates released more than 24 hours
|
|
ago.
|
|
|
|
You can also use the images as a base for your own `Dockerfile`:
|
|
|
|
FROM minideb:jessie
|
|
|
|
Building
|
|
--------
|
|
|
|
You can build an image yourself if you wish:
|
|
|
|
- Install debootstrap and debian-archive-keyring.
|
|
- sudo ./buildall
|
|
|
|
To build an individual image:
|
|
|
|
- sudo ./mkimage jessie.tar jessie
|
|
|
|
To test the resulting image:
|
|
|
|
- docker import -t minideb:jessie jessie.tar
|
|
- ./test minideb:jessie
|
