hazelcast:3.9.2-os docker image cluster does not create a single cluster. about docker HOT 3 OPEN

@mattyarbrough I am not sure but dotCMS may act as the nexus for the Hazelcast servers to see each other. Does the HZ cluster work if you bring up a dotCMS into the mix?

from docker.

@mattyarbrough @wezell I've tried bringing up dotCMS as well but no luck.
I've tested this with the modified docker-compose method from the OP:

1. Using the docker-compose.yml from here: https://github.com/dotCMS/docker/blob/master/referenceImplementations/03-full_stack/docker-compose.yml
2. Add license.zip to 03-full_stack folder
3. Run docker-compose up -d --scale hazelcast=3
4. Then exec into the pod by running docker-compose exec hazelcast sh
5. From inside the pod run wget -O- hazelcast:5701/hazelcast/rest/cluster several times.

I get the same results, each hazelcast instance reports a cluster size of 1 with only itself as the member.

from docker.

@pmooneyarchitech -
Not sure why they are not connecting - Maybe try setting up a hazelcast cluster as described here and then attaching your dotCMS to it - I would try to use the same version as what we are running
