## ✅ Verify Installation
```bash
docker --version
docker-compose --version # For multi-container apps
```
---
## 🔧 Basic Docker Commands
```bash
# Pull an image from Docker Hub
docker pull
# Build an image from Dockerfile
docker build -t : .
# Run a container from an image
docker run -d -p : :
# List running containers
docker ps
# List all containers (including stopped)
docker ps -a
# Stop a running container
docker stop
# Start a stopped container
docker start
# Remove a stopped container
docker rm
# Remove an image
docker rmi :
# View container logs
docker logs
# Exec into a running container
docker exec -it sh
```
---
## 📦 Image Management
```bash
# List local images
docker images
# Tag an image
docker tag : /:
# Push an image to Docker Hub
docker login
docker push /:
# Pull an image from Docker Hub
docker pull /:
# Remove unused images
docker image prune
# Remove all dangling (untagged) images
docker image prune -a
```
---
## 🚀 Container Management
```bash
# Run a container with environment variables
docker run -d \
--name \
-p : \
-e "ENV_VAR=value" \
-v : \
:
# List all containers
docker ps -a
# Stop a container
docker stop
# Remove a container
docker rm
# Check container logs
docker logs
# Check resource usage
docker stats
# Inspect container metadata
docker inspect
```
---
## 🐙 Docker Compose
Example docker-compose.yml:
```bash
version: "3.8"
services:
web:
build: .
ports:
- "5000:5000"
environment:
- ENV_VAR=value
depends_on:
- redis
redis:
image: redis:alpine
```
Common Docker Compose Commands
```bash
# Start services
docker-compose up -d
# Stop services
docker-compose down
# View logs
docker-compose logs
# Rebuild services
docker-compose up --build
# List services
docker-compose ps
```
---
## 🧹 Maintenance & Cleanup
```bash
# Remove unused containers, networks, images, and caches
docker system prune
# Remove all stopped containers
docker container prune
# Remove dangling (untagged) images
docker image prune
# Remove unused volumes
docker volume prune
# Remove all unused resources
docker system prune -a
```
---
## 🐞 Troubleshooting & Debugging
```bash
# Port in use
lsof -i : && kill $(lsof -ti :)
# Permission issues
docker run --user $(id -u) ...
# Check logs
docker logs -f
# View container details
docker inspect
# Monitor container stats
docker stats
```
