This video provides a crash course in using Kubernetes to manage application deployments, including how to set up a deployment, configure it to use default values, and add a MongoDB database.

  • 00:00:00 The Kubernetes Crash Course for Absolute Beginners will teach you everything you need to know to get started with Kubernetes, including the architecture, main components, and practical demo project.
  • 00:05:00 In this video, the main kubernetes components that are used to deploy a web application are introduced. We go through the setup of a worker node, and see how each component plays a role in the deployment process. Finally, we build a simple use case to demonstrate how each component works.
  • 00:10:00 Kubernetes is a system for managing containers, which abstracts away the underlying container runtime. The system provides a virtual network for each pod, and each pod can communicate with each other using its own internal ip address. When a pod dies, a new pod is created in its place with a new ip address. There is also a service component of Kubernetes which allows requests to be routed to specific pods.
  • 00:15:00 In this video, a crash course on Kubernetes is given for absolute beginners. Kubernetes provides an easy way to keep your data persistent, even in the event of a pod restart. The video also covers the use of volumes to store data outside of the Kubernetes cluster.
  • 00:20:00 This video provides a crash course on using Kubernetes to manage applications and databases. Kubernetes allows for easy replication of applications and databases to multiple servers, in case one node fails.
  • 00:25:00 In this video, Kubernetes crash course for absolute beginners, we reviewed the most used Kubernetes components, starting with the pods and services. We also looked at external configuration, using config maps and secrets, and data persistence, using volumes and pod blueprints. Finally, we looked at pod replication mechanisms, like deployments and stateful sets. This information is essential for building basic Kubernetes clusters. Finally, I introduced Castin, who made this video possible. Kessen's K10 is the data management platform for Kubernetes, taking off most of the load of doing backup and restore in Kubernetes from the cluster administrators. With my link, you can download K10 for free and get 10 nodes free forever to do your Kubernetes backups.
  • 00:30:00 In this one-hour video, the presenter explains how mini cubes and cubes control clusters of nodes. Mini cubes are used to test and/or experiment with Kubernetes without setting up a full, production-ready cluster. Cubes allow an administrator to manage a cluster of nodes from a single command line interface.
  • 00:35:00 This video tutorial explains how to use the cube client, mini cube, to create and manage nodes in a Kubernetes cluster. Mini cube can be installed on a machine with sufficient resources, and a local cluster can be created by running the mini cube start command.
  • 00:40:00 In this video, the presenter shows how to create a Kubernetes cluster and deploy a simple application using Kubernetes commands. He also creates a secret and configures a Mongodb service.
  • 00:45:00 Kubernetes provides a set of configuration files that allow for the definition of deployments and services. The configuration files are YAML files and the metadata section defines the names and values for the components of the file. The specification section defines the configuration of the components within the deployment. The template section defines the configuration of the parts within the deployment.
  • 00:50:00 In this video, the Kubernetes Crash Course for Absolute Beginners is introduced, which covers the basics of setting up a Kubernetes deployment. The video covers the concepts of selector matching labels, selector matching pods, and service configurations. Finally, the video covers adding a mongodb deployment and service to the Kubernetes deployment.
  • 00:55:00 This video demonstrates how to create a deployment in Kubernetes for a web application, and how to configure the application and the deployment to use default values for username and password.

01:00:00 - 01:10:00

This video introduces the basics of using Kubernetes to deploy a web application. Environment variables and service configurations are set up, and all of the components needed for the app are created. The app is then deployed, and the logs are checked for any errors.

  • 01:00:00 This video covers how to set up environment variables and service configurations for a web app using Kubernetes. The first environment variable is called username, and the second is for password. The last environment variable is for the database endpoint, which is configured in a secret. Finally, we create all of the components needed for a web app using Kubernetes.
  • 01:05:00 In this video, the basics of Kubernetes are introduced. A Kubernetes cluster is created and various components are listed, including deployments, pods, and services. Finally, a web application is deployed and the logs are examined to check for any problems.
  • 01:10:00 In this video, the presenter demonstrates how to access a web application deployed with its database in Kubernetes, and how to refresh the changes. The presenter also provides links to additional resources if you want to learn more about Kubernetes in depth.
