Ubuntu 32-bit Images for Docker

The Ubuntu 32-bit images for Docker are built the same way as the official Docker Ubuntu 64-bit images. They are based on the Ubuntu cloud images released by Canonical.

For available tags please see the list of tags at Docker Hub.


The images are mainly useful to derive other images from, but can be used standalone like:

$ docker pull f69m/ubuntu32:lts
$ docker run --rm -it f69m/ubuntu32:lts bash


The master branch contains only scripts and config files and has a proper Git history. The dist branch contains the big binary blobs for building the images and will always be a single commit on top of the master branch.


You are welcome to discuss these images, report any issues or contribute changes here on Github, but please stick to topics specific to the 32-bit Docker images. More general contributions should be directed upstream.

Pull requests should only be done for scripts and config files against the master branch. Please do not create pull requests agains the dist branch.

Why 32-bit?

So why make the effort to create 32-bit images? All the nice stuff out there is built for a 64-bit architecture.

Two reasons: for one I sometimes work on an old 32-bit laptop, so running anything with Docker requires 32-bit images.

And then using 32-bit images saves a lot of memory, with negligible impact on the performance. Unless your application is one of the few that can really benefit from 64-bit instructions. So 32-bit images allow running more containers on a cheap VPS. This does save real
