Dockerfile

# A dockerfile to allow simplified (no-installation) execution
# of the OKD Orchestrator.
#
# The Docker image provides you with an OKD orchestrattion enviornment.
# You simply need to mount your orchestrator working dirctory
# (and SSH directory) into it and run image building and orchestration
# from within the container. You can start an denter the container
# using the convenient project script: -
#
#   ./okdo-start.sh
#
# You will need to define suitable environment variables for your
# cloud-provide and, when orchestrating the image IDs for the Bastion and
# Cluster nodes and the OpenShift initial admin account password.
#
# Refer to the project's documention for a detailed discussion of
# the orchestrator.
