Short Description
A small glibc/apt base image designed for use in containers.
Full Description

minideb

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 takes care of some things
for you:

  1. Install the named packages, skipping prompts etc.
  2. Clean up the apt metadata afterwards to keep the image small.
  3. Retrying if apt fails. Sometimes a package will fail to download
    due to a network issue, and this may fix that, which is
    particularly useful in an automated build pipeline.

e.g.

$ install_packages apache2 memcached

The minideb container image is the base image for many Bitnami-maintained
language runtimes including php, nodejs, ruby and infrastructure components
including mariadb, redis, nginx and mongodb.

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 bitnami/minideb:latest

There are tags for the different Debian releases.

$ docker run --rm -it bitnami/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 bitnami/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

Thanks, fixed.

(I wish there was a way to automatically update the description when the repo changes)

I think the documentation is wrong. Directly pull minideb:jessie wasn't working I had to write bitnami/minideb:jessie
