# build-testimage - script for producing a test image for podman CI
|
|
#
|
|
# The idea is to have a small multi-purpose image that can be pulled once
|
|
# by system tests and used for as many tests as possible. This image
|
|
# should live on quay.io, should be small in size, and should include
|
|
# as many components as needed by system tests so they don't have to
|
|
# pull other images.
|
|
#
|
|
# Unfortunately, "small" is incompatible with "systemd" so tests
|
|
# still need a fedora image for that.
|
|
#
|
|
|
