     1  # Heapster Deprecation Timeline
     2  
     3  This is the (proposed) timeline for Heapster deprecation.  Any changes
     4  made to the timeline will be reflected here.  Note that this is the
     5  timeline for the official Heapster repository.  Individual distributions
     6  are encouraged to follow suit in deprecating Heapster, but may continue to
     7  support it on their own.

    17  ## Milestones
    18  
    19  ### Initial Deprecation (Kubernetes 1.11)
    20  
    21  Heapster is marked deprecated as of Kubernetes 1.11.  Users are encouraged
    22  to use
    23  [metrics-server](https://github.com/kubernetes-incubator/metrics-server)
    24  instead, potentially supplemented by a third-party monitoring solution,
    25  such as Prometheus.
    26  
    27  No new features will be added (including, but not limitted to, new sinks,
    28  enhancements to existing sinks, enhancements to sources, and enhancements
    29  to processing).
    30  
    31  The Heapster maintainers will continue to accept bugfixes for critical
    32  bugs.  People filing bugs will be encouraged to reproduce with
    33  metrics-server, and file there.
    34  
    35  Similarly, **the legacy HPA clients and setup flags in Kubernetes should
    36  be marked as deprecated.**
    37  
    38  ### Setup Removal (Kubernetes 1.12)
    39  
    40  Support for installing Heapster will be removed from the Kubernetes setup
    41  scripts.
    42  
    43  Additional warnings will be made in the Kubernetes release notes.
    44  
    45  ### Removal (Kubernetes 1.13)
    46  
    47  Heapster will be migrated to the kubernetes-retired organization.  No new
    48  code will be merged by the Heapster maintainers.
