🛥️ Introduction to Docker: Core Concepts and Basics for Beginners
- Docker lets developers build, ship, and manage their apps in containers, which are isolated environments containing everything needed to run an application.
- Docker is an open-source platform that automates the deployment of applications inside containers.
- The Open Container Initiative (OCI) aims to create industry standards for container runtime and image specifications.
- Containers share the host system's kernel, making them lightweight and fast to start compared to virtual machines (VMs).
- Docker is ideal for microservices and rapid deployments, while bare metal is best suited for high-performance workloads requiring complete control over hardware.
- Docker terminology includes Dockerfile, Image, Container, and Registry.
- Basic docker commands include docker --version, docker help, docker info, docker images, docker pull, docker build, docker rmi, docker tag, docker run, docker ps, docker stop, docker start, docker restart, docker rm, docker exec, docker logs, docker top, docker stats, docker inspect, docker rename, docker network ls, docker network create, docker network connect, docker network disconnect, docker volume ls, docker volume create, docker volume inspect, and docker volume rm.
- Docker makes building, deploying, and running apps using containers efficient, portable, and scalable, which is why they’re at the heart of modern software development.
- If you know Docker and how it works with OCI, you can use this tech to speed up your workflows and ensure your apps work on any platform.
- Docker architecture will be discussed in the next week's article.
