Problem

When Confluence is installed in DC mode, user should be able to set Synchrony node specific options by adding these in synchrony-args.properties located in Confluence home.

Environment

Confluence DC v8.1.1 running in Docker

Steps to Reproduce

1. Create synchrony-args.properties under Confluence home
2. Add the following option to synchrony-args.properties

   synchrony.jvm.arg.hznode=-Dhazelcast.local.publicAddress=192.168.1.100
   

3. Start Confluence with the following Docker run command:

   docker run -v /var/atlassian/application-data/confluence:/var/atlassian/application-data/confluence --name="confluence" -v /mnt/shared:/var/atlassian/application-data/confluence/shared-home -d -p 8090:8090 -p 8091:8091 -p 5801:5801 -e JVM_SUPPORT_RECOMMENDED_ARGS='-Dconfluence.cluster.node.name="ConnieNode2" -Dhazelcast.local.publicAddress=10.108.15.252' -p 25500:25500 -p 5701:5701 -p 54327:54327 atlassian/confluence:8.1.1
   

4. Exec in the docker container and check the Java options for synchrony

   docker exec -it confluence ps -efwww |grep synchrony.core
   

Expected Results

Synchrony process is running with hazelcast.local.publicAddress set.

Actual Results

Synchrony process is not running with hazelcast.local.publicAddress set.

Workaround

Create a symbolic link for synchrony-args.properties under Confluence shared home:

1. In each cluster node create a file named synchrony-args.properties with the required options for the Synchrony process in that node
2. Delete the copy of synchrony-args.properties from Confluence shared home
3. Create a sym link pointing to synchrony-args.properties copy located in Confluence home under Confluence shared home

   # Below example is based on these conditions:
   # 1. Confluence home is /var/atlassian/application-data/confluence/
   # 2. Confluence shared home is /var/atlassian/application-data/confluence/shared-home
   
   sudo ln -s /var/atlassian/application-data/confluence/synchrony-args.properties /var/atlassian/application-data/confluence/shared-home/synchrony-args.properties
   
   # Required for docker as Confluence user id is set to 2002, change the value 2002 to the appropriate username/userid
   
   sudo chown 2002:2002 /var/atlassian/application-data/confluence/shared-home/synchrony-args.properties
