Openshift V2 - Custom Cartridge Permission denied

问题:

I'm trying to listen on a port in open shift, but I'm getting Permission denied. I am using a fork of the Wildfly 8.2.1 Cartridge:

I forked an existing Wildfly Cartridge for Openshift: https://github.com/openshift-cartridges/openshift-wildfly-cartridge

And I added the extra new ports to the manifest.yml file:

- Private-IP-Name:   IP
    Private-Port-Name: HAZELCAST_PORT
    Private-Port:      5701
    Public-Port-Name:  HAZELCAST_PROXY_PORT

The full manifest can be found here: https://github.com/mrj365/openshift-wildfly-cartridge/blob/master/metadata/manifest.yml

I'm not sure what I'm missing. I just want to be able to listen locally on that port.

回答1:

I figured out the issue. Hazelcast was binding to the wrong IP address. I had to add the following configurations to the hazelcast config to get it to work:

Config config = new Config();

config.setProperty("hazelcast.local.localAddress", System.getenv("OPENSHIFT_DIY_IP "));

I'm using wildfly, so for me it was:

config.setProperty("hazelcast.local.localAddress", System.getenv("OPENSHIFT_WILDFLY_IP"));

I also had to add these 2 additional configurations:

config.setProperty("hazelcast.socket.client.bind.any", "false");
config.setProperty("hazelcast.socket.bind.any", "false");
