About this course
This class will prepare you for the Certified Kubernetes Administrator (CKA) exam. You will acquire the knowledge, skills, and abilities to design, implement, and maintain a Kubernetes cluster.
This course covers all objectives and concepts necessary for passing the CKA exam which includes:
- Cluster architecture, installation, and configuration
- Rolling out and rolling back applications in production
- Scaling clusters and applications to best use
- How to create robust, self-healing deployments
You will be provided the components necessary to assemble your own high availability (HA) Kubernetes environment and configure, expand, and control it to meet the demands made of cluster administrators. At the end of a week-long training you will take a mock CKA exam that simulates the real exam.
