Gopkg.lock Initial FrameworkController: General-Purpose Kubernetes Pod Controller Oct 22, 2018


FrameworkController is built to orchestrate all kinds of applications on Kubernetes by a single controller.

These kinds of applications include but not limited to:

  • Stateless and Stateful Service (Nginx, TensorFlow Serving, HBase, Kafka, etc)
  • Stateless and Stateful Batch (KD-Tree Building, Batch Data Processing, etc)
  • Any combination of above applications (Distributed TensorFlow Training, Stream Data Processing, etc)

Why Need It


In the open source community, there are so many specialized Kubernetes Pod controllers which are built for a specific kind of application, such as Kubernetes StatefulSet Controller, Kubernetes Job Controller, KubeFlow TFJob Operator. However, no one is built for all kinds of applications and combination of the existing ones still cannot support some kinds of applications. So, we have to learn, use, develop, deploy and maintain so many Pod controllers.


Build a General-Purpose Kubernetes Pod Controller: FrameworkController.

And then we can get below benefits from it:




Framework Feature

A Framework represents an application with a set of Tasks:

  1. Executed by Kubernetes Pod
  2. Partitioned to different heterogeneous TaskRoles which share the same lifecycle
  3. Ordered in the same homogeneous TaskRole by TaskIndex
  4. With consistent identity {FrameworkName}-{TaskRoleName}-{TaskIndex} as PodName
  5. With fine grained RetryPolicy for each Task and the whole Framework
  6. With fine grained FrameworkAttemptCompletionPolicy for each TaskRole
  7. Guarantees at most one instance of a specific Task is running at any point in time
  8. Guarantees at most one instance of a specific Framework is running at any point in time

Controller Feature

  1. Highly generalized as it is built for all kinds of applications
  2. Light-weight as it is only responsible for Pod orchestration
  3. Tolerate Pod/ConfigMap unexpected deletion, Node/Network/FrameworkController/Kubernetes failure
  4. Well-defined Framework consistency, state machine and failure model
  5. Idiomatic with Kubernetes official controllers, such as Pod Spec
  6. Compatible with other Kubernetes features, such as Kubernetes Service, Gpu Scheduling, Volume, Logging
  7. Aligned with Kubernetes Controller Design Guidelines and API Conventions


  1. A Kubernetes cluster, v1.10 or above, on-cloud or on-premise.
