🛠 Running and Managing Docker Containers

This document provides essential commands and practices to run, manage, and troubleshoot Docker containers effectively.

---

🚀 Running Containers

Run a Container from an Image

Bash

docker run -d --name my-nginx -p 8080:80 nginx

• -d: Detached mode (runs in background)

• --name: Assigns a name to the container

• -p: Maps port 8080 on host to port 80 in container

Run with Interactive Terminal

Bash

docker run -it ubuntu /bin/bash

• -it: Interactive terminal access

Run and Remove After Exit

Bash

docker run --rm alpine echo "Hello, Docker!"

---

📋 Managing Containers

List All Running Containers

Bash

docker ps

List All Containers (including stopped)

Bash

docker ps -a

Start, Stop, and Restart Containers

Bash

docker start <container_id_or_name>
docker stop <container_id_or_name>
docker restart <container_id_or_name>

View Logs

Bash

docker logs <container_name>

Execute Command Inside Container

Bash

docker exec -it <container_name> /bin/bash

---

🧼 Clean Up

Remove a Container

Bash

docker rm <container_id_or_name>

Remove All Stopped Containers

Bash

docker container prune

Remove All Unused Resources

Bash

docker system prune -a

⚠️ Use with caution – this will remove unused containers, networks, volumes, and images.

---

🧪 Inspect and Debug

Inspect Container Details

Bash

docker inspect <container_name>

Resource Usage (CPU, memory, etc.)

Bash

docker stats

Network Inspection

Bash

docker network ls
docker network inspect <network_name>

---

📌 Tips

• Name containers meaningfully for easier management

• Use docker-compose for multi-container apps

• Monitor logs and resource usage for performance issues

• Tag and version your images clearly
