What is Minideb
A minimalist Debian-based image built specifically to be used as a base image for containers.
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:stretch
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
Why use Minideb
- This image aims to strike a good balance between having small images, and having many quality packages available for easy integration.
- The image is based on glibc for wide compatibility, and has apt for access to a large number of packages. In order to reduce size of the image, some things that aren't required in containers are removed:
- 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)
These images also include an
install_packagescommand that you can use instead of apt. This takes care of some things for you:
- Install the named packages, skipping prompts etc.
- Clean up the apt metadata afterwards to keep the image small.
- 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.
$ install_packages apache2 memcached
Adoption of Minideb
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. Please feel free to submit an issue request so that we can reach out and help you quickly.
We provide a Makefile to help you build Minideb locally. It should be run on a Debian based machine and requires sudo privileges.
$ sudo make
To build an individual release (stretch, jessie or unstable)
$ sudo make stretch
To test the resulting image:
$ sudo make test-stretch
