Maybe Im just approaching this wrong.
Single Instance mode (non-HA)
AWS-RDS Postgres Database
Deploying via ECS
Currently have Artifactory-Pro building a docker container and deploying to ECS via CI/CD. The initial deploy goes fine. Everything stands up, database migrations occur, and the instance runs.
However, when doing an update to the task, a new task spins up. It then adds entries to the access_topology with the new container-ip and unique node-id, but they stay unhealthy. The logs just then bomb out with failure messages (below - due to existing heartbeat of other node).
If I first stop the running task, and start a new task, it spins up properly (Probably due to heartbeat loss).
In typical ECS world, the new task is spun up till its deemed healthy, and then the older task is killed off.
Either scenario creates orphaned NODE records that stay healthy -- trying to also figure out how to garbage collect on those and purge.
Any thoughts on this?
Errors are below – it appears that it wont properly join because of an active heartbeat, and not being HA. However, I want this node to stand up so I can topple the other. Thanks –

This is not possible without an HA configuration. Since this is not an HA configuration, the application will not start up if there is another application still "alive". In this case, "alive" is defined as having written the heartbeat within X amount of seconds (I believe this is 10 by default).
