New in This Release

Version 1.0.1 of the MapR Data Fabric for Kubernetes can be used:
  • On cluster nodes that are installed with MapR software only (MapR 5.2.2 or later)
  • On cluster nodes having both MapR software (MapR 6.0.1 or later) and Kubernetes software

This release of the MapR Data Fabric for Kubernetes includes a set of Docker containers and their respective .yaml configuration files that can be installed onto a Kubernetes cluster. Once installed, these containers provide a Kubernetes FlexVolume Driver for file system and a Kubernetes Dynamic Volume Provisioner that permit static and dynamic provisioning of MapR storage from Kubernetes.

Fixes

None.

Known Issues and Limitations

Note these limitations:
  • Version 1.0.1 supports installing MapR 6.0.1 or later and Kubernetes software on the same nodes. However, not all versions of the MapR Data Fabric for Kubernetes support this feature. To identify other versions that support coexistence, see the MapR Data Fabric for Kubernetes release notes.
  • All nodes in the Kubernetes cluster must use the same Linux OS. Configuration files are available to support these Linux distributions:
    • CentOS
    • RedHat (use CentOS configuration file)
    • SSE (use CentOS configuration file)
    • Ubuntu
  • Docker for Mac with Kubernetes is not supported as a development platform for containers used with the MapR Data Fabric for Kubernetes.
  • Volume plug-in files are supported for:
    • CentOS
    • Ubuntu
    • Microsoft Azure AKS
    • Red Hat OpenShift**
    • Google Kubernetes Engine (GKE)
  • Amazon EKS is not supported.
  • The Basic POSIX client package is included by default when you install the MapR Data Fabric for Kubernetes. The Platinum POSIX client can be enabled by specifying a parameter in the Pod spec. Only the POSIX client is supported. NFSv3 is not supported.

**OpenShift Origin is supported because it supports Kubernetes 1.9. The OpenShift Container Platform (formerly known as OpenShift Enterprise) can be used only if it supports Kubernetes 1.9.
