@kmova kmova released this May 24, 2019

Getting Started

Prerequisite to install

  • Kubernetes 1.12+ is installed
  • Make sure that you run the below installation steps with cluster admin context. The installation will involve creating a new Service Account and assigning to OpenEBS components.
  • Make sure iSCSI Initiator is installed on the Kubernetes nodes.
  • NDM helps in discovering the devices attached to Kubernetes nodes, which can be used to create storage pools. If you like to exclude some of the disks from getting discovered, update the filters in NDM Config Map to exclude paths before installing OpenEBS.
  • NDM runs as a privileged pod since it needs to access the device information. Please make the necessary changes to grant access to run in privileged mode. For example, when running in RHEL/CentOS, you may need to set the security context appropriately. Refer Configuring OpenEBS with selinux=on

Using kubectl

kubectl apply -f

Using helm stable charts

helm repo update
helm install  --namespace openebs --name openebs stable/openebs
