[Buildroot] [PATCH 0/4 v2] support/docker: add new dockers (branch yem/dockers)

[Yann E. MORIN]

Hello All!

Enhance our docker support, update the existing image, add a new one.

This will help:

  - users, to get a build environment known to work,

  - developpers, to more easily reproduce build failures reported by
    users.

A basic set of a few, very various distros have been chosen, to cover
a range of diversity:

  - the existing, rock-solid Debian Stretch, pinned to a known state,
    that we use for the Gitlab-CI testing;

  - Fedora-F32, a bleeding-edge mainstream distro, pinned to the state
    it was at release time;

More variants can be added later, depending on the demand.

Note: when this series is applied (if it is), I'll generate the images
and push them to the Buildroot repo on the Docker hub.

Changes v1 -> v2:
  - reorder patches to ensure bisectability  (Ricardo)
  - drop the Makefile rule in favour of a script
  - drop Arch and Alpine for now...


Regards,
Yann E. MORIN.

[Buildroot] [PATCH 1/4 v2] support/docker: rename the Dockerfile and its accompanying file

[Yann E. MORIN]

Currently, we only generate one docker image, for use by the gitlab-ci
infra.

However, users have expressed an interest in using that image for other
uses, like:

  - reproducing build failures as reported by the gitlab-ci jobs;

  - having a ready-to-use base image to use as-is, or as a template for
    further customisations.

Additionally, some users have reported the need for similar base images,
but based off different distros, with the same goals as above, plus:

  - reproducing build failures reported by users on other distros.

As a first step toward providing such images, rename our Dockerfile to
include the name and version of the distro it is based off.

We add a symlink so that we still have a 'base' image that we can
reference from the gitlab-ci infra.

[Buildroot] [PATCH 3/4 v2] support/docker: allow the br-user to becone root

[Yann E. MORIN]

When our Dockerfiles (and images) get reused by users, they might need
to locally add new packages or tweak the iamge to heir local needs.

As such, register the br-user to become root by running (exactly!):
    $ sudo su -

This will allow acutally becoing root without prompting for a password,
but no other command will be accepted, and no other paramter will be
accepted either.

[Buildroot] [PATCH 4/4 v2] support/docker: add a Fedore-32 based image

[Yann E. MORIN]

Hopefully, this image is reproducible, since we are not using any update
repository, and from the looks of it, the repository of the release is
never touched.

[Buildroot] [PATCH 4/4 v2] support/docker: add a Fedore-32 based image

[Thomas Petazzoni]

Hello,

Thanks for doing this work, I did need some Docker images just
yesterday. One comment/question below.

With python-nose2 and python-pexpect, this pulls in a Python
interpreter, which is not strictly a requirement of Buildroot. I know
these are needed to run the runtime tests, and therefore to run the
Gitlab CI stuff. But sometimes we need to do some tests with really the
minimal set of Buildroot dependencies. Same goes with qemu-system-*
packages.

Should we have two sets of Docker images, one with the minimal set of
dependencies, and one that adds the stuff needed for Gitlab CI ? I
believe Docker allows to create some kind of layered "thing" where an
image sits on top of another.

This Docker image could be used by toolchain-builder project instead of
reinstalling every time packages needed by Buildroot:

https://github.com/bootlin/toolchains-builder/blob/master/.gitlab-ci.yml.in

Note: openssh-client is used to upload build artifacts and the toolchain archive
to the Bootlin server. So we still need admin right to install some package.

Best regards,
Romain
