While this "Kubernetes explained" video reviews the core native functionality of the container management platform, IT admins can also consider Kubernetes add-on components, such as a DNS to handle network names, a dashboard for a web-based Kubernetes management interface and resource monitoring and logging tools that can gather and report on Kubernetes cluster metrics and … Kubernetes architecture: Master and API server. They are portable across clouds, different devices, and almost any OS distribution. Kubernetes architecture explained The Kubernetes command-line interface is called kubectl. 1 Kubernetes Architecture explained . The pod serves as a ‘wrapper’ for a single container with the application code. Like most distributed computing platforms, a Kubernetes cluster consists of at least one master and multiple compute nodes. Its service then works to align the two states and achieve and maintain the desired state. Kubernetes - Cluster Architecture. The Kubernetes control panel records, implements, and runs background reconciliation loops that continuously check to see if the environment matches user-defined requirements. Like containers, it is designed to run anywhere, including on-prem, private, public cloud, and even in the hybrid cloud. For example The Twelve-Factor App approach where connectivity between application layer and data persistence layer is done via HTTPS and often UI part of the application is served as a static web app or SPA.. One key difference in Kubernetes world and more broadly, in the … Pods are not constant. A service automatically discovers a new pod with labels that match the selector. The agreed-upon origin is from the Greek, meaning “helmsman” or “sailing master.” It is the entry point of all administrative tasks. Kubernetes objects explained. In order to get a deeper understanding, you are highly encouraged to deploy each of the components separately and setup their communication from scratch. Based on that information, the Master can then decide how to allocate tasks and resources to reach the desired state.
