 If you want to get a job in software these days, you really need to know about Docker. So Docker uses a technology called containers, which is kind of like the idea of shipping containers. You can pack several together and they can each hold many different things. A Docker container is a lightweight, standalone, executable package that includes everything needed to run a piece of software, including the code, the runtime, libraries, environment variables and config files. Docker containers provide a consistent way to package and deploy applications, making this ideal for microservices or other distributed applications. They can be deployed with many technologies like Kubernetes or AWS Elastic Container Service, and it's easy to scale them as needed. They allow developers to easily move their applications between development, testing, and production environments, without having to worry about dependencies or configuration differences between them. So I hope you've learned something new about Docker in this video, and consider subscribing if you like this content.
