Containers are the future of application development and hosting. They enable DevOps, developers, and system administrators to build, test, deploy, and maintain applications quickly, securely, and efficiently. Tools built around the containerization concept provide simple solutions for basic web applications. These advanced granular configuration options provide the control many enterprise applications may need.
Kubectl is a command-line tool for Kubernetes. It allows us to execute Kubernetes operations via the API. We can use Kubectl to deploy apps, check logs as well as manage all the other resources of the cluster.
Kubernetes uses an HTTP-based REST API which is the actual Kubernetes user interface employed to manage it. This means that every Kubernetes operation is represented as an API endpoint and can be carried out based on an HTTP-request sent to the endpoint.
In this article, we will review Kubectl, and outline its installation, configuration, and use.
A virtual machine is a simulated computer system which runs on a physical computer. In other words, a virtual machine is a computer inside a computer. Virtual machines allocate memory, a virtual CPU, disk storage space, and a network interface. This means that we can have a Windows computer that runs multiple virtual machines composed of Ubuntu Linux, macOS, Windows 10, Solaris, and CentOS, and they will all be completely separate from our parent Windows operating system.
Minikube is the name of a software program written in Go, which can build a local Kubernetes cluster on a single host. It uses a meager amount of resources to run a mini Kubernetes deployment. Minikube is mainly used for testing purposes using different scenarios or versions of Kubernetes
With the constant technological development we are witnessing in the world of hosting, it is necessary to familiarize ourselves with the terminology and meaning of the systems we are using. An important distinction that we need to make is between virtual machines and containers, as they are both widely used in the hosting industry, and yet they are often confused.
