Sametime 12 install.sh on linux uses the command "docker-compose" that needs to be installed separately. Regarding documentation at docker this command is deprecated and "docker compose" (the docker compose plugin) should be used instead.
Are there plans to update the install.sh to use this new "docker compose"?
I thought you do need docker compose if you plan to distibute containers accross multiple machines, if not (which is the case for sametime on Docker which can use only one machine) you still can use docker-compose (which is an aliasing to docker compose).
If you want to deploy sametime accross multiple instances, then you need to use kubernetes to deploy sametime.
