Is anyone else having problems with upgrading services in their stacks on Rancher 1.6?
I often get errors like this:
“Failed to allocate instance [container:1i113198]: Bad instance [container:1i113198] in state [error]: Allocation failed: Host must satisfy resource constraints: [60545:3000/tcp portReservation]. needs host with label environment.type: production”
This is trying to do a simple upgrade of a service in a stack, where the service stops and then pulls a new image and spins up a new container.
Often, rolling back then also fails, and you have to delete the service in the hope that is gets re-created again by Rancher.
This seems to have been a problem since at least 1.6.15.
