CMAPI REST server
Overview
This RESTfull server enables multi-node setups for MCS.
Requirements
See requirements.txt file.
All the Python packages prerequisits are shipped with a pre-built Python enterpreter.
Usage
To run the server using defaults call:
python3 -m cmapi_server
There is a configuration server inside cmapi_server.
Testing
To launch the integration and unit tests use unittest discovery mode.
python3 -m unittest discover -v mcs_node_control
python3 -m unittest discover -v cmapi_server
python3 -m unittest discover -v failover
mcs_control_node unit tests ask for root privileges and additional systemd unit to run smoothly.
