Description

I got message no suitable node (scheduling constraints not satisfied on 3 nodes; unsupported platform on 1 node) and I don't know which node has unsupported platform because all of them is running as virtual machines (3 masters, 1 worker). All has x86_64 and linux. So I don't know where is the problem.

Suggestion

As a part of the message https://github.com/docker/swarmkit/blob/master/manager/scheduler/filter.go#L315 show also Node.Description.Hostname, Node.Description.Platform.OS, Node.Description.Platform.Architecture.

Research direction

Read manager/scheduler/filter.go around line 315, where the unsupported-platform message is assembled. Trace the scheduling error path and use Node.Description.Hostname, Node.Description.Platform.OS, and Node.Description.Platform.Architecture as the requested diagnostic context. Done means the message identifies the node and its platform details when this filter rejects it.
