D: Docker has revolutionized the way developers build, ship, and run applications. πŸ›³οΈ Whether you’re a beginner or an experienced developer, mastering Docker commands can significantly improve your workflow. Let’s dive into the most essential Docker commands that will supercharge your productivity! ⚑


1. Getting Started with Docker

πŸ”Ή Check Docker Version

Before anything else, verify your Docker installation:

docker --version

Output:

Docker version 20.10.12, build e91ed57

πŸ”Ή Pull an Image from Docker Hub

Need a pre-built image? Use docker pull:

docker pull nginx:latest

This downloads the latest Nginx image. πŸ—οΈ


2. Managing Containers

πŸ”Ή Run a Container

Start a container from an image:

docker run -d -p 8080:80 --name my-nginx nginx
  • -d β†’ Run in detached mode (background)
  • -p 8080:80 β†’ Map host port 8080 to container port 80
  • --name β†’ Assign a custom name

πŸ”Ή List Running Containers

Check active containers:

docker ps

For all containers (including stopped ones):

docker ps -a

πŸ”Ή Stop & Remove a Container

Stop a running container:

docker stop my-nginx

Delete it permanently:

docker rm my-nginx

3. Working with Images

πŸ”Ή List Downloaded Images

See all local images:

docker images

πŸ”Ή Remove an Image

Free up space by deleting unused images:

docker rmi nginx

πŸ”Ή Build a Custom Image

Create a Dockerfile and build:

docker build -t my-app:1.0 .
  • -t β†’ Tag the image (name:version)

4. Advanced Productivity Boosters

πŸ”Ή Execute Commands Inside a Running Container

Need to debug? Access the container shell:

docker exec -it my-nginx /bin/bash
  • -it β†’ Interactive terminal

πŸ”Ή View Container Logs

Check application logs:

docker logs my-nginx

πŸ”Ή Copy Files Between Host & Container

Transfer files easily:

docker cp my-nginx:/etc/nginx/nginx.conf ./nginx.conf

5. Cleanup & Maintenance

πŸ”Ή Remove Unused Containers, Networks, & Images

Keep your system clean:

docker system prune

Add -a to remove all unused images (not just dangling ones).


🎯 Pro Tips for Maximum Efficiency

βœ… Use Docker Compose for multi-container apps.
βœ… Leverage volumes (-v) for persistent data.
βœ… Automate builds with CI/CD pipelines.
