OpenEBS CLI#
OpenEBS is developing a kubectl plugin for openebs called openebsctl that can help perform administrative tasks on OpenEBS volumes and pools.
Refer openebsctl for more information and detailed instructions on how to get started with OpenEBS CLI.
OpenEBS Monitoring Add-on#
OpenEBS is developing a monitoring add-on package that can be installed via helm for setting up a default prometheus, grafana, and alert manager stack. The package also will include default service monitors, dashboards, and alert rules.
Refer Monitoring for more information and detailed instructions on how to get started with OpenEBS Monitoring Add-on.
Data Populator#
The Data populator can be used to load seed data into a Kubernetes persistent volume from another such volume. The data populator internally uses Rsync, which is a volume populator having the ability to create a volume from any rsync source.
Use Cases#
- Decommissioning of a node in the cluster: In scenarios where a Kubernetes node needs to be decommissioned whether for upgrade or maintenance, a data populator can be used to migrate the data saved in the Local Storage (a.k.a Local Engine) of the node, that has to be decommissioned.
- Loading seed data to Kubernetes volumes: Data populator can be used to scale applications without using read-write many operation. The application can be pre-populated with the static content available in an existing PV.
Refer Data Populator for instructions on the installation and usage of Data Populator.
