What is Rancher ? Rancher Labs is a software company working on operating-system-level virtualization tools, more commonly known as Linux Containers. Founded in 2014, Rancher Labs introduced two main tools: Rancher, a container management platform for Docker container systems, and RancherOS , a Linux operating system distribution simplified to host containers. [1] What is kubernetes ? Kubernetes (commonly stylized as k8s ) is an open-source container - orchestration system for automating application deployment, scaling, and management. It was originally designed by Google, and is now maintained by the Cloud Native Computing Foundation . It aims to provide a "platform for automating deployment, scaling, and operations of application containers across clusters of hosts". It works with a range of container tools, including Docker . Many cloud services offer a Kubernetes-based platform or infrastructure as a service ( PaaS or IaaS ) on which Kubernetes can...

What is VPN ? A virtual private network ( VPN ) extends a private network across a public network, and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. Applications running on a computing device, e.g., a laptop, desktop, smartphone, across a VPN may therefore benefit from the functionality, security, and management of the private network. Encryption is a common, though not an inherent, part of a VPN connection.[1] What is Docker ? [2] Docker Engine is an open source containerization technology for building and containerizing your applications. Docker Engine acts as a client-server application with: A server with a long-running daemon process dockerd . APIs which specify interfaces that programs can use to talk to and instruct the Docker daemon. A command line interface (CLI) client docker . This article describes how to install a VPN (Virtual Private Network) ser...
