Gentoo Docker Images

Build Status

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 /usr/portage volume



  • portage
  • stage3
    • stage3-amd64
      • stage3-amd64-hardened
      • stage3-amd64-hardened-nomultilib
      • stage3-amd64-nomultilib
      • stage3-amd64-systemd
    • stage3-x86
      • stage3-x86-hardened

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:

TARGET=stage3-amd64 ./

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.

Example Dockerfile

# 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:


  • 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
You can’t perform that action at this time.
