corda generating node info manually (--just-generate-node-info) forces host lookup

问题

I am trying to generating node-info files for a few nodes running in our cloud. I bring up these nodes within separate containers. I have tried corda 3.1 and 3.2

I use the command:

java -jar corda.jar --just-generate-node-info

The result is (in the log file of the node):

*java.net.UnknownHostException: controllercontainer

This is true using the network-bootstapper-corda-3.0.jar as outlined here: https://medium.com/coinmonks/running-corda-dlt-with-kubernetes-3f21c15d4dd8

Is there a way around this, or am I supposed to generate these files using a different method.

回答1:

I was working on Windows. My workaround to create NodeInfo manually is modifying hosts file in "C:\Windows\System32\drivers\etc" and map the hostname to 127.0.0.1

回答2:

Thanks to Joel for pointing to the slack thread that had the answer.

Simply adding the option: detectPublicIp=false

in the node.conf prevents IP lookup
