github hashicorp/nomad v1.1.0

1.1.0 (May 18, 2021)


  • Memory oversubscription: Improve cluster efficiency by allowing applications, whether containerized or non-containerized, to use memory in excess of their scheduled amount.
  • Reserved CPU cores: Improve the performance of your applications by ensuring tasks have exclusive use of client CPUs.
  • UI improvements: Enjoy a streamlined operator experience with fuzzy search, resource monitoring, and authentication improvements.
  • CSI enhancements: Run stateful applications with improved volume management and support for Container Storage Interface (CSI) plugins such as Ceph.
  • Readiness checks: Differentiate between application liveness and readiness with new options for task health checks.
  • Remote task drivers (technical preview): Use Nomad to manage your workloads on more platforms, such as AWS Lambda or Amazon ECS.
