### Deploying OpenEBS on Kubernetes for Debian/Ubuntu based OS
## Baseline Guide: https://github.com/openebs/cstor-operators/blob/develop/docs/quick.md
# Type of Deployment: Helm

### Minimum Requirements ###
## Three Worker Node Cluster (Tested on K0s, K3s, K8s)
## Each worker node must have a blank drive to consume, if you need to wipe said drives, use: dd if=/dev/zero of=/dev/sdb bs=1M
#
## The following base packages are required:
# JQ, tool to parse JSON output
apt-get install -y jq && \
# Helm, Package Manager
curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 && \
chmod 700 get_helm.sh && \
./get_helm.sh && \
#
### Installation ###
# Install the Helm chart repo
helm repo add openebs-cstor https://openebs.github.io/cstor-operators && helm repo update && \
# Deploy OpenEBS
helm install openebs openebs-cstor/cstor --create-namespace --namespace openebs && \
# If there are any issues with the following commands. you can check for block devices: kubectl get bd -n openebs
# Set the blockdevice names created to variables
WORKER1=$(kubectl get bd -n openebs -l kubernetes.io/hostname=worker-node-1 -o json | jq -r ".items[].metadata.name")
WORKER2=$(kubectl get bd -n openebs -l kubernetes.io/hostname=worker-node-2 -o json | jq -r ".items[].metadata.name")
WORKER3=$(kubectl get bd -n openebs -l kubernetes.io/hostname=worker-node-3 -o json | jq -r ".items[].metadata.name")
