Summary
AppsCode held a webinar on “MariaDB Auto-Scaling and Reconfiguration in Kubernetes Native way using KubeDB”. This took place on 17th Feb 2022. The contents of what took place at the webinar are shown below:
- Deploy KubeDB Provisioned MariaDB Cluster
- Volume Expansion
- Reconfigure MariaDB
- Storage Autoscaling
- Compute Autoscaling
- Q&A Session
Description of the Webinar
It is required to install the followings to get started:
- KubeDB Provisioner
- KubeDB Ops-Manager
- KubeDB Autoscaler
- Prometheus
- Metrics Server
- Vertical Pod Autoscaler
- Topolvm Provisioner(Or any storageclass that allows volume expansion)
Live demo of the webinar is started with provisioning a MariaDB Cluster of 3 nodes using KubeDB Provisioner Operator. When the cluster got ready, Volume Expansion OpsRequest by KubeDB Ops-Manager is performed to expand the volume of each node from 1Gi to 2Gi.
After that, Another OpsRequest Reconfigure is performed on the MariaDB cluster to reconfigure the MariaDB server values like max_connections and read_buffer_size. Applyconfig option of Reconfigure OpsRequest is also demonstrated.
Then speaker talked about the new feature Autoscaler that can automatically scale different database resources like storage, memory and cpu. Following, A Storage Autoscaler was deployed on the MariaDB cluster which was triggered by raising the volume usage to more than 20%.
Lastly, It’s shown how to deploy Compute Autoscaler with some configurations and how it takes recommendation from vertical pod autoscaler and creates Vertical Scaling OpsRequest.
