Docker is a platform that allows developers to easily deploy, run, and manage applications in a containerized environment. Containers allow for consistent and reproducible environments, making it easier to move an application from development to production.
To use Docker efficiently, it’s important to understand the basics of how it works. A Docker container is a lightweight, standalone executable package that includes everything needed to run a piece of software, including the code, runtime, system tools, libraries, and settings.
Here are some basic commands to get started with Docker:
docker run: This command is used to start a new container from a given image.docker pull: This command is used to download a given image from a Docker repository.docker images: This command is used to list all images that are currently stored on the host machine.docker ps: This command is used to list all running containers.docker stop: This command is used to stop a running container.
It’s also important to note that you can use docker-compose which help you to configure and run multi-container applications with ease.
It’s also a good practice to keep your images small and to avoid installing unnecessary packages in containers. Additionally, you can use a .dockerignore file to exclude files and directories from the build context that are not needed in the image.
Finally, you can use Docker in the cloud services like AWS ECS, GCP GKE and Azure AKS to run your containers in a production environment.
