IT giants like Google, Amazon, and Microsoft are providing various enriching career opportunities to Docker professionals. Docker is a software containerization platform that helps you to package applications with their dependencies into standardized units for better software development. While docker runs on any operating system, there are certain benefits to choosing a docker host OS that is specific to your needs.
Here, we'll cover the best OS for Docker, benefits of running Docker on a specific OS and give you tips on selecting the best OS for Docker. So whether you're getting started with Docker or looking to jumpstart your career with a credible Docker course, this article will help.
Docker is a lightweight software platform that enables developers to create virtual environments for their applications. Dockers isolate their applications from the underlying host operating system, simplifying management and deployment . Docker is used for running software packages named "containers". They usually include their own libraries, configuration files, and tools; they can communicate with each other via well-defined channels. All the containers are operated by a single Docker OS kernel and thus require fewer resources than a virtual machine.
Docker containers provide an additional layer of abstraction and automation of operating-system-level virtualization on Linux and Windows. As a result, Docker has become a popular choice under DevOps courses online for developing and deploying cloud-native applications for career advancement.
Here is the list of best OS for Docker:
Boot2Docker is a lightweight Linux distribution designed to run Docker containers. It includes everything you need to get started with Docker, including a kernel with support for virtualization and a bootloader that can launch Docker images. It is designed to be easy to use, and it runs completely from a USB drive or SD card.
You can even install it on a Windows or Mac machine using VirtualBox. Once installed, Boot2Docker will automatically download the latest version of Docker and set up a virtual machine that can run Docker containers. If you’re just a beginner, Boot2Docker is the best OS for docker you can get. It can be used without having to install a full Linux distribution.
RancherOS is a minimalistic Linux distribution designed specifically for running containers. By simplifying the operating system and removing unnecessary components, RancherOS makes it easier to deploy and manage containers at scale. The operating system includes only the bare minimum required to run containers, such as a kernel, init system, and container runtime.
This minimalist approach reduces the surface area for potential security vulnerabilities and minimizes the number of resources required to run the operating system. It also includes built-in orchestration tools that make it easy to deploy and manage containerized applications. As a result, RancherOS is an ideal docker OS for macOS and windows to run containers in production environments.
Ubuntu Core is a minimalistic version of Ubuntu. Initially, it is designed for, and most suitable for, containers of apps and IoT devices in the form of Ubuntu Core. The fact that Docker is a rather lightweight itself makes it a great candidate to serve this rather minor, well-thought, positively light-built characteristic and stability.. As for the differences among them, Ubuntu Core can be lighter in terms weight and can be used on constrained tools/devices, IoTs, Edge bases.
Highlights of Ubuntu Core:
Alpine Linux is another lightweight Linux distribution, known for its simplicity and small size. It is specifically designed for power users who need a minimalistic and highly efficient OS for running containers.
Alpine Linux's minimalism makes it ideal for creating small and efficient Docker images. Its secure environment, provided busybox, ensures that applications run reliably. The apk package manager is both fast and easy to use, allowing for quick installation and management of dependencies.
Highlights of Alpine Linux :
Data center Operating System or DC OS is a container platform developed by Mesosphere that is used for corporate and commercial data centers. Mesosphere DC/OS is designed to scale, which may be advantageous to large enterprises. Its integrated services help to address the requirements for deploying and managing containerized applications in an organizational environment.
Highlights of Mesosphere DC/OS :
Fedora Linux is one of the most loved, contemporary, progressive Linux distribution with a great deal of community base. It offers a stable middleware for deploying Docker containers, especially in the development and the testing environments.
Fedora Linux is ideal for developers who want access to the latest technologies. Its modularity allows for flexibility in managing software versions and dependencies. The integration of SELinux provides robust security mechanisms, protecting containerized applications. With extensive documentation and a strong community, Fedora Linux is an excellent choice for development and testing environments, particularly when leveraging Docker OS for container management and orchestration.
Highlights of Fedora Linux:
If you’re planning to use Docker OSX for your business or daily needs, here are some factors to consider when making your decision:
Containerized applications tend to be very resource-intensive, so it's important to choose an OS that can provide the power and resources they need to run smoothly.
A Docker host exposes a number of ports that could be exploited by attackers, so it's important to choose an OS that has robust security measures in place.
When you're running containers in production, you want to make sure you have a reliable support system in place in case something goes wrong.
Consider the version of the Docker Engine that's included with the host OS. The latest version of the Docker Engine is always recommended for production use.
Finally, you'll want to consider the ease of use when choosing a Docker host OS. Some operating systems are easier to use than others. If you're new to Docker, you may want to choose an OS that's easy to install and configure.
Docker is a powerful tool, and it’s important to choose the best OS for Docker in order to take full advantage of its capabilities. It is a big part of what makes containerization so powerful, and it’s growing more popular every day. Kubernetes is also on the rise and is quickly becoming the standard for managing containers at scale.
When looking for a rewarding career, Docker and Kubernetes are two of the most important skills to learn. These technologies are revolutionizing the way we think about computing, and they show no signs of slowing down.
With the industry's best Docker and Kubernetes course available, you can learn everything you need to know. Hopefully, you found this article helpful as you make your decision about which Docker OS will work best for you and your business.
Any Linux OS can be used for docker but we prefer Boot2Docker or RancherOS. There are many reasons why you would want to choose one over the other. Boot2Docker is a better choice for Windows and Mac OS X users because it provides an easy way to get started with Docker. Whereas, RancherOS is very good at running containers and positively impacts your development environment.
Docker containers will run on any operating system that supports the Docker engine including all major Linux distributions, as well as MS Windows and macOS. The only requirement is that the host operating system must have a kernel that supports containerization.
Docker desktop macOS and Windows are supported for several years now, and it is typically included in the default installation of these operating systems. As a result, there should be no problem running Docker containers on either of these platforms.
Windows containers are based on either Windows Server Core or Nano Server, which are slimmed-down versions of Windows designed to be more efficient for running containers. Docker containers can be run on Windows 10 and Windows Server 2016 without any additional configuration required. However, you must install the Docker daemon on your server before using containers.
Yes, Docker is free to use for Linux (as well as Windows and Mac). However, there are some points to consider. First, a pay-for subscription is required for commercial use of Docker in large enterprises (over $10 million USD in revenue per year or more than 250 employees).
In addition, if you want to deploy Docker containers in a production environment, you will need to purchase a support plan from Docker.
