Docker Hands-on Workshop Chennai - 3 days

Learn to Work with Docker Basic to Advanced Operations

Docker has been a game-changer when it comes to how modern applications are deployed and architectured. It has now grown into a key driver of innovation beyond system administration, with an impact on the world of web development and more. But how can you make sure you're keeping up with the innovations it's driving

Docker is an open source containerization engine that offers a simple and faster way for developing and running software. Docker containers wrap software in a complete filesystem that contains everything it needs to run, enabling any application to be run anywhere – this flexibility and portability means that you can run apps in the cloud, on virtual machines, or on dedicated servers.
