This is a master issue for bring docker service logs to general availability. There is still work to do to bring them out of experimental.

  • Details (blocked, see Docker Logs HTTP Format is Ambiguous #31956)
• Containers with TTYs ([WIP] Refactor Container Logs and support TTY for Service Logs #31952)
• Verify support for non-JSON logging drivers (docker service logs hangs with non-json logging driver #28793)
• Fix formatting (Service logs formatting #31672)

Bugs (Can be worked on during code freezes)
