ebuildtester 44

A container approach to test a Gentoo package within a clean stage3 container

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

Requirements

Using require Docker and FUSE.

If you plan to use specific storage driver options (by passing --storage-opt), be aware that these are specific to the configured Docker storage driver. Refer to the Docker documentation about storage drivers for more information. Particularly see the list of options per storage driver.

System-wide configuration of the storage driver used by Docker is done in /etc/docker/daemon.json. For example, to select the devicemapper storage driver, specify:

{
  "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:
