The course is part of this learning path
This training course is designed to help you master the skills of deploying cloud-native applications into Kubernetes.
Observe first hand the end-to-end process of deploying a sample cloud-native application into a Kubernetes cluster. By taking this course you'll not only get to see firsthand the skills required to perform a robust enterprise-grade deployment into Kubernetes, but you'll also be able to apply them yourself as all code and deployment assets are available for you to perform your own deployment:
This training course provides you with in-depth coverage and demonstrations of the following Kubernetes resources:
- Ingress/Ingress Controller
- Persistent Volume
- Persistent Volume Claim
- Headless Service
What you'll learn:
- Learn and understand the basic principles of deploying cloud-native applications into a Kubernetes cluster
- Understand how to set up and configure a locally provisioned Kubernetes cluster using Minikube
- Understand how to work with and configure many of the key Kubernetes cluster resources such as Pods, Deployments, Services, etc.
- And finally, you’ll learn how to manage deployments and Kubernetes cluster resources through their full lifecycle.
This training course provides you with many hands-on demonstrations where you will observe first hand how to
- Create and provision a Minikube Kubernetes cluster
- Install the Cilium CNI plugin
- Build and deploy Docker containers
- Create and configure Kubernetes resources using kubectl
- A basic understanding of containers and containerization
- A basic understanding of software development and the software development life cycle
- A basic understanding of networks and networking
- Anyone interested in learning Kubernetes
- Software Developers interested in Kubernetes containerization, orchestration, and scheduling
- DevOps Practitioners
- [Instructor] Okay, welcome back. From here on in, we're actually deploying to our Kubernetes cluster. And this is really the fun part, which we've worked really hard for. We've done all of the set-up work, and performed all of the necessary container packaging.
Let's now move ahead and have some fun deploying and creating resources within our Kubernetes cluster. For starters, we'll navigate into the voteapp-k8s directory. This contains all of the Kubernetes' declarative yaml resource files that, when applied into the cluster, will tell Kubernetes what our desired end state is. And Kubernetes will go ahead and perform all of the necessary provisioning to achieve that end goal. As you can see, the root director contains several sub directories, which are used to collate the yaml files into the main components that make up our deployment. Within each sub folder, we have ordered the files using the as seen naming convention. This allows us to deploy at the folder level using the kubectl command.
Okay, we'll start off by deploying a custom namespace into our cluster, to segment and isolate all of our resources into this one namespace. Which, as you can see, is named cloudacademy. We'll use the kubectl apply command, together with the dash f parameter to specify the yaml file we want to apply into the cluster like so.
Okay, with the namespace now created, we can change and apply the current context to be set to the namespace of cloudacademy, using the following command. Okay, that completes our namespace set-up. And we are ready to deploy the remainder of our cloud native application resources into it.
