Docker

In addition to the command line parameters described above, netcallback can be configured using environment variables. This allows configuration consistent with what one might expect to deploy in a containerized Docker environment. The environment variables are:

• NCB_SERVER_TYPE
• NCB_SERVICE_PORT
• NCB_SERVICE_HOST
• NCB_INITIAL_ANONYMOUS_PORT
• NCB_FINAL_ANONYMOUS_PORT
• NCB_TCP_HOST
• NCB_TCP_PORT
• NCB_UDP_HOST
• NCB_UDP_PORT
• NCB_SSL

Running a Docker container might look like this

docker run -d -p 8081:8081 -p 9999:9999 -p 57000-57100:57000-57100 \
-e NCB_SERVER_TYPE=public \
-e NCB_SERVICE_PORT=9999 \
-e NCB_TCP_PORT=8081 \
-e NCB_INITIAL_ANONYMOUS_PORT=57000 \
-e NCB_FINAL_ANONYMOUS_PORT=57100 \
--restart=always --name netcallback netcallback

docker run -d -p 9999:9999 \
-e NCB_SERVER_TYPE=private \
-e NCB_SERVICE_HOST=10.200.100.10 \
