Docker is the industry-leading containerisation technology, currently possessing ~95% market share. The Docker and Kubernetes technologies are used together. Docker allows you to “create” containers and Kubernetes helps you to “manage” containers.
Containers are empowering businesses to scale fearlessly and manage their web applications hassle-free. They are the prime reason why micro and small enterprises are migrating to the cloud. All of this has undoubtedly led to an enormous demand for professionals with containerization skills.
The course starts with an introduction to Docker and explains how it helps in developing web applications. Next, you will explore the architecture of Docker and become familiar with Docker images, Docker files, and containers.
By the end of this course, you will have all the skills needed to build, deploy, and manage containerized web applications on local premises and on the cloud using Kubernetes and Docker.
