Hi! It's nice of you to give it a try!

This project is still in development, so not everything is perfect. I need a bit more information on your issue:

  1. Which instructions? Have you read the wiki? Specifically https://github.com/BrainDoctor/clustercode/wiki/Cluster-Settings
  2. Are you running in Swarm mode? If yes, I fear you need to figure it out by yourselves, as I don't have such a setup and cannot test it.
  3. Which image tag are you running? The latest is 1.0.9/stable from Docker Hub as of now.
  4. What are your settings/env variables that differ from the defaults?

hi, thanks for the response. not running swarm, and i set the compose file to latest.
the modified compose file is
version: "2.0"
services:
clustercode:
restart: always
image: braindoctor/clustercode:latest
container_name: clustercode
cpu_shares: 512
ports:
- "7600:7600/tcp"
volumes:
- "/sorcu/ToConvert:/input"
- "/sorcu/Converted:/output"
- "~/sorcu/clusterconfig:/usr/src/clustercode/config"
environment:
- CC_CLUSTER_JGROUPS_TCP_INITAL_HOSTS=192.168.0.13[7600],192.168.0.100[7600],192.168.0.101[7600],192.168.0.102[7600],192.168.0.103[7600]
- CC_CLUSTER_JGROUPS_EXT_ADDR=192.168.0.104

the first one in the list of hosts there also has the arbiter flag set to true and is being run in docker on my synology nas

i have also tried modifying the properties file directly to set the network settings as follows

Try the stable image please. Latest is be a bit behind, as I'm doing some internal rework. The stable got a few bugfixes in the meantime.

You don't need to modify the .properties file if you are using environment variables. Env vars always take precedence. Also I noticed a typo in your env var CC_CLUSTER_JGROUPS_TCP_INITAL_HOSTS. INITAL should be INITIAL (missing i letter). I don't think that's the issue if you set it again the properties file though.

I assume that every other node has similar initial hosts?

aha, fixing the typo and switching to stable seems to have helped, thanks :)

good to know. If you have further problems or suggestions please report them :)
