Docker is an open-source tool for shipping, developing, and running applications within a Linux container, which is a lightweight virtual machine. It has many tools and features that provide categorised applications using the Docker index or your docker registry. It is used to manage and build applications and provide a platform for simplifying the deployment of numerous complex applications. We will discuss What is Docker Linux and Why Shout you use Docker. Join Linux Training In Chennai. It offers advanced certification training and 100% job placement assistance.
Docker Linux
Docker Linux is an open-source platform for categorising and deploying applications. It assists developers in packaging various applications in a Linux container. It provides a platform for standardised executable components that can be used to combine and run application source code in any environment. Its popularity is skyrocketing as more businesses transition to cloud-native and hybrid cloud development.
Developers can build containers without the use of Docker. On the other hand, Docker makes building, managing, and deploying containers easier, simpler, better, and safer. Docker is an essential toolkit for developers because it allows them to build, run, update, manage, and deploy containers using simple commands. It also provides time-saving APIs for automation.
Docker, also known as Docker Inc., sells the commercial version of Docker and the Docker Open Source Project. Docker Inc. and numerous other organisations have gathered to contribute to Docker’s open-source projects.
Why Use Docker?
During the early stages of development, Linux Docker was created in the Linux kernel, allowing for the visualisation of a single instance of Linux.
Docker has altered and improved native categorisation with technologies that enable:
Improved and Seamless Portability
Linux Containers (LXC) frequently work with machine-specific configurations, whereas Docker containers can run on any cloud platform, data centre, or desktop without modification.

Lighter and Faster
A Docker container can only run one process at a time, making it much faster and lighter than others. It can build an application while one of its components is being updated or changed.
Automated Container Creation
Docker also offers automated containers based on application source code.
Container Reuse
Existing containers can also create and deploy new containers as base images.
Open-Source Libraries
Docker developers have access to many open-source repositories containing thousands of containers contributed by users and other organisations.
Docker Linux Container
Docker Linux containers are created by the Linux kernel’s built-in process isolation and virtualisation capabilities. Control groups are used to distribute resources among processes, and namespaces are used to limit process access.
Multiple virtual machines can share a single hardware server’s CPU, memory, and other resources using these containers. As a result, containers offer a variety of virtual machine functionalities and features, including application isolation, cost-effectiveness, and a few others, which are listed below:
Lightweight
Virtual machines contain the payload of an entire operating system and the hypervisor, but Docker containers do not. They only include processes and dependencies required for the operating system to run. Container sizes are measured in megabytes (some virtual machines have sizes in gigabytes), making them faster to boot and more cost-effective at hardware stores.
Greater Resource Efficiency
Containers can run any application multiple times on the same hardware as virtual machines, reducing cloud space requirements.
Improved Developer Productivity
Containers are faster, easier, and better than virtual machines for building, deploying, and managing applications, making them ideal for developers’ various use cases.
