I am fine with not documenting how to do it for the 2.8 release, the same for the official Apache Pulsar Helm Chart. but currently there is no way to deploy the Transaction Coordinator as a standalone module, if there is a way to launch an isolated TC please let me know otherwise I will at least create an issue on github and hopefully we can implement it for Pulsar 2.9.0, when transactions will be hopefully considered fully stable.
