[fujitatomoya]

Feature request

Motivation

Supporting docker container image for persistent parameter server, so that user can use the persistent parameter server with docker run ... with host network to their system right away.

Feature description

• Integrate workflow to verify the building container images for each distribution.
• Release container images for each distribution when need to do basis.
• Add explanation how to start the container for user documentation, probably binding host system network and file system including the yaml parameter files from the host system
• Be advised that [container main process] needs to be persistent parameter server, instead persistent parameter server cannot shutdown with storing the persistent parameters in the file system. see more details for [Question] Use param server in docker containers and with docker compose #24. For doing this, i believe for now, we need to use wrapper script to source the workspace and start the executable binary with container entrypoint.
