DOCKER CONTAINERS AND KUBERNETES
A 2-day intro course to containers and K8s
This technical "workshop style" course covers the core Docker and Kubernetes concepts and guides you to build, deploy and monitor containers on Kubernetes. Developers, DevOps and I.T. Pros will learn how to use containers locally and in the cloud. You’ll experience several demos and hands-on "live coding" activities with the trainer throughout the course as you learn how to build, deploy and monitor containers. No coding experience is required for the hands-on activities since the focus is on DevOps but you'll use the terminal, command prompt and VS Code extensively.
In this course, you will deploy Kubernetes on DigitalOcean, a small cloud provider but large enough to have a Canadian data centre. 😲Wait! Not Azure, AWS or GCP? You might now say "I don't have a Digital Ocean account and I don't plan to use them." No problem because the concepts you'll learn in this course will be applicable to the big 3 providers. To reach a broader audience (Azure, AWS and GCP) for this course, we use DigitalOcean as a "neutral" cloud provider because it's super easy to use and by using this link, you get $100 of free credits to spend in the first 60 days of your DigitalOcean account creation so no cloud usage costs for you and no conflicts with your cloud account that you may have at work. You see, it's a no brainer 😀
In day 1, you'll learn about microservices and their use cases. You'll then learn about containers, Docker and to use the Docker CLI. You'll then learn about Kubenernetes, it's concepts and how to deploy and manage microservices applications packaged in containers locally. This will provide you the essential foundation that you'll need before heading to the cloud.
In Day 2, you'll apply what you learned so far to the cloud. You'll create and connect to a Kubenernetes cluster in the cloud and deploy applications. You'll learn how to use essential tools like Helm, Ingress and service meshes so that you can deploy, manage and maintain applications on Kubernetes like a ninja!

WHY IS THIS FOR ME?
You're new to containers and Kubernetes. You're a developer and you've been tasked to containerize an application to be hosted on Kubernetes. You want to understand the concepts so you can build and test containers locally. You also want to learn how microservices hosted in Kubernetes works so you can architect and develop the system accordingly.
No matter what development platform you use, this course will help you achieve your goals. Note that the course focus is on DevOps topics and you'll use VS Code to create configuration files, not coding actual apps.
You're new to containers and Kubernetes. As the DevOps specialist in your team, you want to understand containers, how to build and test them locally, how to configure and manage applications on Kubernetes.
This course will help you achieve your goals as it focuses on DevOps topics. You'll use VS Code intensively to create configuration files and deploy readily made apps (no coding required) with CLI commands in the terminal or command prompt.
You're new to containers and Kubernetes. As the I.T. Pro in your team, you want to understand containers and how to configure Kubernetes in the Cloud so you can monitor and scale the system in production.
Note that the course focus is on DevOps topics and you'll use VS Code to create configuration files and deploy readily made apps (no coding required). Advanced I.T. Pro topics are not covered in this course.
The following setup is required on your laptop to attend this course:
A detailed checklist will be emailed to the attendees in the week prior to the course.
