Gentoo Docker Images
A collection of Dockerfiles for generating Gentoo docker images.
These images are intended to be created automatically by
a travis cron job and pushed to docker hub.
This repository include basic stage3 images and an image usable as a
Building the containers
The containers are created using a multi-stage build, which requires docker-17.05.0 or later. The container being built is defined by the TARGET environment variable:
Using the portage container as a data volume
docker create -v /usr/portage --name myportagesnapshot gentoo/portage:latest /bin/true docker run --interactive --tty --volumes-from myportagesnapshot gentoo/stage3-amd64:latest /bin/bash
Using the portage container in a multi-stage build
docker-17.05.0 or later supports multi-stage builds, allowing the portage volume to be used when creating images based on a stage3 image.
# name the portage image FROM gentoo/portage:latest as portage # image is based on stage3-amd64 FROM gentoo/stage3-amd64:latest # copy the entire portage volume in COPY --from=portage /var/db/repos/gentoo /var/db/repos/gentoo # continue with image build ... RUN emerge -qv www-servers/apache # or whichever packages you need
We'd love to hear any ideas. Feel free to contact us via any of the following methods:
- IRC: irc://freenode.net/#gentoo-containers
- EMAIL: email@example.com
- GITHUB: https://github.com/gentoo/gentoo-docker-images
- Use topic branches (i.e. foo) and fix branches (i.e. fix/foo) when submitting pull requests
- Make meaningful commits ideally with the following form:
- Subject line–what this commit does
- Blank line
- Body–why this commit is necessary or desired
- Pull requests should not include merge commits
- Use amend and rebase to fix commits after a pull request has been submitted
