Up and Running with Kubernetes: A Practical Approach
Learn the basics of container orchestration and management
Topic: System Administration
Containers provide a fluid approach to computing by separating the underlying hardware (real or virtual) from the application. Kubernetes is an open-source container-orchestration system used for automating application deployment, scaling, and management. Originally designed by Google it is now maintained by the Cloud Native Computing Foundation. Kubernetes works with a range of container tools including Docker.
Kubernetes can be considered a container operating system where application resource and storage needs are matched to an underlying cluster environment (either virtual or real). This course provides both background for users coupled with a practical hands-on introduction to Kubernetes.
What you'll learn-and how you can apply it
- Understand the problem Kubernetes solves
- Learn the components of a Kubernetes cluster
- Understand how Kubernetes components interact with each other
- Learn how to start a small virtual Kubernetes cluster (Minikube) on a laptop
- As a Kubernetes user, create and run simple container examples on Minikube
- Learn about the four major versions of Kubernetes available in the cloud
This training course is for you because...
- You are not sure what Kubernetes actual does or why it used
- You want to understand how to manage containerized applications from a user perspective
- Hands-on experience is important to you when learning a new technology
- You need to learn the basics of Kubernetes quickly
- The ability to continue exploring and implementing after the class is important
The hands-on portion of the course is done using the Linux command line. The course assumes familiarity using the command line on a modern Linux server. Those skills and topics are covered in the following live online training courses:
Beginning/Intermediate Linux Command Line for Data Engineers (search O'Reilly Learning for upcoming dates)
Please be aware, if you have no experience with the Linux command line, you may find this course difficult to follow.
- To run the class examples, the Minikube virtual machine will be used (https://minikube.sigs.k8s.io/). Versions are available for Windows, Mac, and Linux.
- Attendees are invited to download the virtual machine prior to class, however download and installation instructions/examples will be provided as part of the class.
