Maintaining, Monitoring and Troubleshooting Kubernetes
This course will teach you to maintain, monitor and troubleshoot production Kubernetes clusters.
What you'll learn
Troubleshooting production in Kubernetes clusters can be difficult. In this course, Maintaining, Monitoring and Troubleshooting Kubernetes, you’ll learn to maintain, monitor, and troubleshoot Kubernetes Clusters. First, you’ll learn core cluster maintenance tasks such as etcd backup and restore operations, upgrading an existing Kubernetes Cluster, and facilitating for Worker Node maintenance and high availability cluster topologies. Next, you’ll discover how to quickly find and analyze performance monitoring and logging data in your cluster. Finally, you’ll explore core tools and techniques for troubleshooting your cluster. When you’re finished with this course, you’ll have the skills and knowledge of maintaining, monitoring, and troubleshooting needed to operate and manage Kubernetes Clusters. This course can also help you prepare for your Certified Kubernetes Administrator (CKA) certification.
