📄️ What is Docker
Docker is an open-source platform that allows you to automate the deployment, scaling, and management of applications using containerization. It provides a way to package software applications and their dependencies into standardized units called containers. These containers are isolated, lightweight, and portable, making it easier to deploy and run applications across different environments.
📄️ How to create a Dockerfile?
Docker is used to create, run and deploy applications in containers. A Docker image contains application code, libraries, tools, dependencies and other files needed to make an application run. When a user runs an image, it can become one or many instances of a container. In this tutorial we will be creating ubuntu image:
📄️ Build your First Docker Image
Building your first Docker image is an exciting step towards containerizing your application. Docker allows you to package your application and its dependencies into a portable and reproducible image. Follow these steps to build your first Docker image:
📄️ Start Docker Image
After building a Docker image, the next step is to start a container based on that image. Starting a Docker container allows you to run your application in an isolated and reproducible environment. Follow these steps to start a Docker image as a container:
📄️ Push Docker Image to Docker Hub
Once you have built a Docker image, you may want to share it with others or deploy it to different environments. Docker Hub is a popular cloud-based registry that allows you to store and distribute Docker images. Follow these steps to push your Docker image to Docker Hub:
