Introduction

This script is a tool to test a Gentoo ebuild and its dependencies. The idea is that the package is emerged in a clean (and current) stage3 Docker container.

Requirements

You require Docker and FUSE. Docker must be configured to use the devicemapper storage driver. This can be achieved with the following inside /etc/docker/daemon.json:

{
  "storage-driver": "devicemapper"
}

Usage

We are going to assume that the user has a local git clone of the portage tree in

/usr/local/git/gentoo

We have added a new ebuild and would like to verify that the build dependencies are all correct. We can build the package (ATOM) with:

ebuildtester --portage-dir /usr/local/git/gentoo \
  --atom ATOM \
  --use USE1 USE2

where we have specified two USE flags, USE1 and USE2. The ebuildtester command will now create a docker container and start installing the ATOM. All specified dependencies will be installed as well.

Command line arguments

The command understands the following command line arguments:

usage: ebuildtester [-h] [--version] [--atom ATOM [ATOM ...]] [--binhost BINHOST] [--live-ebuild]
                    [--manual] --portage-dir PORTAGE_DIR [--overlay-dir OVERLAY_DIR] [--update]
                    [--install-basic-packages] [--threads N] [--use USE [USE ...]]
                    [--global-use GLOBAL_USE [GLOBAL_USE ...]] [--unmask ATOM] [--unstable]
                    [--gcc-version VER] [--python-single-target PYTHON_SINGLE_TARGET]
                    [--python-targets PYTHON_TARGETS] [--rm]
                    [--storage-opt STORAGE_OPT [STORAGE_OPT ...]] [--with-X] [--with-vnc]
                    [--profile PROFILE] [--docker-image DOCKER_IMAGE] [--pull]

A dockerized approach to test a Gentoo package within a clean stage3.
