Having Cromwell service a Unix socket
I am trying to have Cromwell webservice on a Unix socket (file) rather than the loopback interface (e.g. default port 8000).
However, I am unsure how to setup the config of cromwell. I have naively tried setting the
websevice.port to the socket path with obvious results:
Caused by: com.typesafe.config.ConfigException$WrongType: system properties: port has type STRING rather than NUMBER at com.typesafe.config.impl.SimpleConfig.findKeyOrNull(SimpleConfig.java:163) at com.typesafe.config.impl.SimpleConfig.findOrNull(SimpleConfig.java:174) [...]
Any suggestions or help would be very welcome.
Context: we are running instances of the cromwell server on a shared compute cluster. Having the server listen to a port on the host loopback interface (i.e. localhost:8000) is a security risk whereas using the Unix socket would allow us to set permissions.
P.S. I am running Cromwell v37 on Mac OS Sierra (10.12.6).
