portage-u20-runner.dockerfile

## Dockerfile for building and running Portage on Ubuntu 20.04
# 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-u20-builder -f portage-u20-builder.dockerfile .
# Step 2: build the runner image, a leaner image with only the runtime software:
#    docker build --tag portage-u20-runner -f portage-u20-runner.dockerfile .

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