If you are looking for a container orchestration platform, Ridge’s Container Service might be the right choice for you. The inner workings of Docker and where containers fit in can be seen in the following diagram: Need a lightweight setting due to hardware constraints.Need to scale up or tear down your application.Operate on Continuous-Integration and Continuous Delivery (CI/CD) workflows.Once your development and testing phase is complete, you can deploy your application to the main production environment. Moreover, you can store or share these container images through Docker Hub (or a similar registry). With Docker Engine, you can run several containers on a given host without worrying about what’s installed on the host itself. Docker comes to the rescue here, by streamlining the container creation process. Now, imagine having to deal with all these dependencies on your system and push the new changes to the main server-every single time. Use-case example of DockerĪny conventional application will use a database to store user data, a framework to add new features, and a programming language to hold it all together. While the concept of managing containers is not new, it’s the “reduced time and faster-deployment” marketing that has made Docker popular, so much so that the words ‘container’ and ‘docker’ are often used interchangeably. It enables you to segment your application from its infrastructure and deploy it quickly on a cloud-premise (or localhost). Now that we know what containers are, we may ask: How are they related to Docker?įor further reading, we have a whole article on What Are Containers.ĭocker is an open-source containerization platform launched by the company Docker Inc. in 2013. They can be easily transferred from one environment to another and work uniformly throughout. Unlike Virtual Machines, containers only virtualize the operating system and thus are lightweight.
However, Virtual Machines contain an extra hardware layer making them heavy, complex, and less mobile.
What is kubernetes and how to use it install#
This means that a standalone container image is enough for you to run an application on your system without having to install any additional packages.Ĭontainers are often compared to Virtual Machines, as the latter also provides resource isolation. What makes containers so popular is their ability to provide abstraction and isolation of resources. This not only allows an application to run quickly on a system but also makes it portable, easy to transfer from one environment to another.
Let’s start with the first and most basic one: containers.Ī container is like a compact box holding an application’s dependencies all in one place. In this article, we’ll clear up the misconceptions surrounding the “Docker vs Containers vs Kubernetes” debate and provide a thorough understanding of the overall hierarchy.
