What’s Docker?
Docker is a software platform that allows you to easily build, package, and deploy applications in a consistent and portable manner. It achieves this by using containerization technology, which allows you to isolate your application and its dependencies into a self-contained package called a "container."
Some of the use cases for Docker include:
- Application development: Docker provides a lightweight and portable environment for developers to build and test their applications. Developers can easily create a container with all the necessary dependencies and configurations, which can be shared with other developers or deployed to different environments.
- Continuous integration and deployment: Docker can be used to automate the building, testing, and deployment of applications. Continuous integration tools can use Docker to build and test applications in isolated environments, while continuous deployment tools can use Docker to deploy applications to production environments.
- Microservices architecture: Docker is well-suited for building microservices-based applications, where each microservice is packaged as a separate container. This approach allows for easy scaling, updates, and maintenance of individual microservices without affecting the rest of the application.
- Hybrid and cloud environments: Docker allows for easy deployment of applications to hybrid and cloud environments. Containers can be easily moved between different environments, allowing for greater flexibility and scalability.
Overall, Docker provides a way to simplify the process of building, deploying, and managing applications, making it a popular choice for many software development teams.
I’ve found that video so useful on explaining what docker is on short.
to start working with Docker, you will need to download and install docker for you OS.
you can find the windows installation link here.
Install Docker
First, install Docker on your machine:
While setting it up locally you may face some problems such as you will need to enable virtualization in your machine, or you may need to update your windows, you can always google the error prompt to find the solution.
