# Dockerfile for a generic Ubuntu image with just the basics we need
|
|
# to make it suitable for CI. In particular:
|
|
# * a non-root user to run as (a pain to try to do in setup,
|
|
# because by then we've already cloned the repo);
|
|
# * Git and other basic utilities.
|
|
#
|
|
# Based on CircleCI's provided images, but those are on Debian Jessie
|
|
# and we want Ubuntu, to match our supported environments in production.
|
|
# See these templates and code:
|
|
# https://github.com/circleci/circleci-images/blob/1949c44df/shared/images/
|
|
# which we've borrowed from, chiefly Dockerfile-basic.template.
|
|
#
|
|
# The CircleCI `python` images are based on upstream's `python` (i.e.,
|
|
# https://hub.docker.com/_/python/), which also come only for Debian
|
|
# (and various obscure distros, and Windows) and not Ubuntu. Those
|
|
# are in turn based on upstream's `buildpack-deps`, which do come in
|
|
# Ubuntu flavors.
|
|
#
|
|
# So this image starts from `buildpack-deps`, does the job of `python`
|
|
# (but much simpler, with a couple of packages from the distro), and
|
|
# then borrows from the CircleCI Dockerfile.
|
|
|
|
# To rebuild from this file for a given release, say trusty:
|
|
# 0. $ tools/circleci/generate-dockerfiles
|
|
# 1. pick a new image name, like `gregprice/circleci:trusty-python-3.test`
|
|
# 2. $ sudo docker build tools/circleci/images/$RELEASE/ --tag $NAME
|
|
# 3. $ sudo docker push $NAME
|
|
# 4. update .circleci/config.yml to refer to the new name
|
