nreqs.Dockerfile

#
# Simple dockerfile to create an image that can run the TCF client
#
# Build as:
#
#  # cd .../tcf.git
#  $ buildah bud -t tcf -v $PWD:/home/work/tcf.git:O --label version="$(git describe --always)" -f client.Dockerfile
#
# Run under the container without registry::
#
#  $ podman run -v $HOME/.tcf:/home/work/.tcf:O tcf ls
#
# Push to a registry::
#
#  $ buildah push localhost/tcf REGISTRY/IMAGENAME/tcf:latest
#
# Run under the the container::
#
#  $ podman run -v $HOME/.tcf:/home/work/.tcf:O tcf tcf ls
#
# don't use fedora-minimal or it'll start pruning things we need (like /usr/share/zoneinfo)

# We also add multiple tools for diagnosing that at the end we always need
# chmod: when we run inside Jenkins, it'll use which ever UID it uses
#        (can't control it), so we need /home/work world accesible
# pip3 install: our setup is a wee messed up at this point
#               sed -> quick hack because it's late and I am done with this
# rm -rf : leftover lib from pip3 removed
# chmod: when we run inside Jenkins, it'll use which ever UID it uses
#        (can't control it), so we need /home/work world accesible
#
# Note --skip-packages=tcf-client to nreqs; we try to install in this
# container images all the deps needed to build TCF itself, but it picks
# up also the ones needed to run the server (the client package) so
# when building the container we tell it to skip that.
