portage-c7-runner.dockerfile

## Dockerfile for running Portage on CentOS7
# Optional preliminary steps, in the Portage-SMT-TAS root directory (allows
# choosing a particular branch or version - otherwise, these are automatically
# downloaded from GitHub when needed):
#    git clone https://github.com/nrc-cnrc/PortageTMXPrepro.git tmx-prepro
#    git clone https://github.com/nrc-cnrc/PortageTrainingFramework.git framework
#    git clone https://github.com/nrc-cnrc/PortageTextProcessing.git third-party/PortageTextProcessing
#    git clone https://github.com/nrc-cnrc/PortageClusterUtils.git third-party/PortageClusterUtils
#    download PortageII-4.0-test-suite-systems.tgz from the GitHub release assets here
# Step 1: build the builder image, which can also be used for running Portage:
#    docker build --tag portage-c7-builder -f portage-c7-builder.dockerfile .
# Step 2: build the runner image, a leaner image with only the runtime software:
#    docker build --tag portage-c7-runner -f portage-c7-runner.dockerfile .

## TODO: configure a user-mountable volume for doing experimental work.

FROM centos:7 as runner

## Reuse an old yum cache
# Potential optimization, especially useful when network is slow.
# Given a previously built image which is running, run
#   docker cp <imageid>:/var/cache/yum ./saved-yum-cache
# to save its yum cache for reuse here.
COPY saved-yum-cache? /var/cache/yum
