## Project Purpose
OpenEBS is an open-source storage service for Kubernetes applications. OpenEBS manages the block storage and file systems based on the block storage for containers running in Kubernetes. Use OpenEBS for creating fast and resilient storage; with options for single-node, and replicated multi-node storage.

## Monthly Community Meetings
OpenEBS holds a monthly community meeting via Zoom on the last Thursday of the month, at 14:00 UTC.
The next meeting is on: `Thursday 31 October, at 14:00 UTC`
Meeting Link: https://us05web.zoom.us/j/87535654586?pwd=CigbXigJPn38USc6Vuzt7qSVFoO79X.1
Starting in August 2024, the meetings will be recorded and posted on YouTube. [Check here](https://www.youtube.com/@openebscommunity6021)
## Why OpenEBS?
OpenEBS provides enterprise-grade data management for Kubernetes clusters, with five storage engines (four single-node and one replicated) that meet a range of use cases for Kubernetes users. The five engines are summarized in the table below:
> [!IMPORTANT]
> The OpenEBS platform, provides 2 types of K8s Storage Services. ```Replicated PV``` and ```Local PV```.
| Engine | [Local PV HostPath](https://github.com/openebs/dynamic-localpv-provisioner) | [Local PV ZFS](https://github.com/openebs/zfs-localpv) | [Local PV LVM](https://github.com/openebs/lvm-localpv) | [Local PV Rawfile](https://github.com/openebs/rawfile-localpv) | [Replicated PV Mayastor](https://github.com/openebs/mayastor) |
| :---: | :--- | :--- | :--- | :---: | :---: |

## Deployment
- In-cloud: (AWS EC2/EKS, Google GCP/GKE, Azure VM/AKS, Oracle OCI, IBM/RedHat OpenShift, Civo Cloud, Hetzner Cloud... and more)
- On-Premise: Bare Metal, Virtualized Hypervisor infra using VMWare ESXi, KVM/QEMU (K8s KubeVirt), Proxmox
- Deployed as native K8s resources: ```Deployments```, ```Containers```, ```Services```, ```Stateful sets```, ```CRD's```, ```Sidecars```, ```Jobs``` and ```Binaries``` all on K8s worker nodes.
- Runs 100% in K8s userspace. So it's highly portable and runs across many OSs & platforms.

## QUICKSTART : Installation
```NOTE: ``` Depending on which of the 5 storage engines you choose to deploy, pre-requisites must be met. [See detailed quickstart docs...](https://openebs.io/docs/)
> 1. **Setup helm repository.**
```Erlang
# helm repo add openebs https://openebs.github.io/openebs
# helm repo update
```
> 2a. **Install the Full OpenEBS helm chart with default values.**
> - This installs **ALL OpenEBS Storage Engines*** in the openebs namespace and chart name as openebs:
> ```Local PV Hostpath```, ```Local PV LVM```, ```Local PV ZFS```, ```Replicated PV Mayastor```
```Erlang
# helm install openebs --namespace openebs openebs/openebs --create-namespace
```
> 2b. **To Install just the OpenEBS ```Local PV``` Storage Engines, use the following command**:
```Erlang
# helm install openebs --namespace openebs openebs/openebs --set engines.replicated.mayastor.enabled=false --create-namespace
```
> 3. **To view the chart**
```Erlang
# helm ls -n openebs
Output:
NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
openebs openebs 1 2024-06-25 09:13:00.903321318 +0000 UTC deployed openebs-4.1.0 4.1.0
```
> 4. **Verify installation**
> - List the pods in namespace
> - Verify StorageClasses
```Erlang
# kubectl get pods -n openebs
Example Ouput:
