Available options:
build - locally builds simulator image from existing code
start - starts simulator and netopeer2 containers using remote simulator image and specified model name
start-dev - starts simulator and netopeer2 containers using remote simulator image
start-debug - starts only netopeer2 container
run-simulator - starts sending PNF registration messages with parameters specified in config.json
stop-simulator - stop sending PNF registration messages
stop - stops both containers
status - prints simulator status
clear-logs - deletes log folder
Starting simulation:
- Setup environment with "./simulator.sh start". It will download required docker images from the internet and run them on docker machine
- To start the simulation use "./simulator.sh run-simulator", which will start sending PNF registration messages with parameters specified in config.json
To stop simulation use "./simulator.sh stop-simulator" command. To check simulator's status use "./simulator.sh status".
If you want to change message parameters simply edit config.json, then start the simulation with "./simulator.sh run-simulator" again
Logs are written to logs/pnf-simulator.log. After each "start/start-dev" old log files are moved to the archive
FOR DEVELOPERS
1. Build local simulator image using "./simulator.sh build"
2. Run containers with "./simulator.sh start-dev"
If you change the source code you have to rebuild image with "./simulator.sh build" and run "./simulator.sh start/start-dev" again
