Today, most organizations rely on Docker and its tools. With the introduction of Docker, the software development process has transformed, and thus, it has been widely adopted by most organizations, irrespective of their business size.
Why Learn Docker?
Docker makes the application development and deployment process simpler by creating, deploying, and running containerized applications on any required platform. Naturally, the Docker developers are in great demand. Not only developers but organizations are also emphasizing learning Docker basics to figure out its implementation.
There is no better time than now to start learning a new technology. DevOps has become the top priority within the organizations, and it necessitates learning Docker and related tools to make the DevOps pipeline smoother and efficient.
There are many options and sources that you can consider for learning Docker and its related tools. You can either go for personal training, which may not always be feasible, or you can go for self-learning from various online or offline tutorials, which are available anytime, anywhere.
Going for online courses is not only a great way to learn but also to stay up-to-date with changing tools and technologies, and evolving tech trends.
In the below article, we will suggest various online Docker courses that you can consider. But before getting into the details, we will give you a summary of what Docker is and why we should integrate it with our development process.
What is Docker?
Docker has become a must-have tool for all DevOps developers. With the help of Docker and containers, you can work without having system dependencies. Docker reduces the effort for developers and enhances productivity by focusing on what’s important without worrying about the platform where the application will run.
The container platform allows you to build, test, and run the containerized applications on the platform where you can install Docker. Due to this portability, you can migrate the container applications from one platform to another without getting into the systems’ configuration details.
Docker solves the purpose of running multiple containers in a more efficient way and with less overhead as compared to VMs. Docker does not require to have a complete OS instance but shares the kernels of the host OS. It helps optimize resource usage.
No one container interferes with the others. Implementing Docker brings you several benefits and allows you to run applications on cloud-native platforms.
Advantages of Docker
- You can start Docker within seconds without the overhead as a Docker container is a process running on the operating system.
- Docker helps in ensuring a faster software deployment process. With Docker, there is no need to create an entirely new environment. You only need to download the Docker image for a particular server where you want to run the container.
- The popular containerization platform scales and maintains the containers seamlessly. It allows you to run multiple containers bundled with applications and their dependencies on the same host or server.
- Docker optimizes the resources efficiently as these resources are being shared by multiple containers running on the same server.
