COMMON USEFUL DOCKER COMMANDS

Here are some common Docker commands for managing containers, images, networks, and volumes:

Run a container:
```
 docker run -d --name <container-name> <image-name>
```
- Runs a container in detached mode (-d) from the specified image.
- Example: docker run -d --name my-nginx nginx
List running containers:
```
 docker ps
```
- Shows all currently running containers.
- Add -a to list all containers, including stopped ones.

Stop a container:

 docker stop <container-id|container-name>

Remove a container:
```
 docker rm <container-id|container-name>
```
- Deletes a stopped container.
- Use -f to force-remove a running container.

Build an image:
```
 docker build -t <image-name>:<tag> <path-to-dockerfile>
```
- Builds an image from a Dockerfile.
- Example: docker build -t my-app:latest .
List images:
```
 docker images
```
- Lists all images available on the host.
Remove an image:
```
 docker rmi <image-id|image-name>
```
- Deletes an image.
- Use -f to force-remove an image if it’s being used.
Pull an image from a repository:
```
 docker pull <image-name>:<tag>
```
- Downloads an image from Docker Hub or other registries.
- Example: docker pull ubuntu:latest

List networks:
```
 docker network ls
```
- Shows all Docker networks.
Create a network:
```
 docker network create <network-name>
```
- Creates a new Docker network.

Connect a container to a network:

 docker network connect <network-name> <container-name>

Inspect a network:
```
 docker network inspect <network-name>
```
- Shows detailed information about a Docker network.

Create a volume:
```
 docker volume create <volume-name>
```
- Creates a new volume for persistent storage.
List volumes:
```
 docker volume ls
```
- Lists all Docker volumes.
Remove a volume:
```
 docker volume rm <volume-name>
```
Inspect a volume:
```
 docker volume inspect <volume-name>
```
- Shows detailed information about a volume.

View container logs:
```
 docker logs <container-id|container-name>
```
- Displays logs from a specific container.
- Use -f to follow the logs in real-time.
Access a running container’s shell:
```
 docker exec -it <container-id|container-name> /bin/bash
```
- Starts an interactive shell inside a running container.
- Example: docker exec -it my-nginx /bin/bash
Tag an image:
```
 docker tag <image-name> <repository>/<image-name>:<tag>
```
- Tags an image to prepare it for pushing to a registry.
- Example: docker tag my-app myrepo/my-app:latest
Push an image to a registry:
```
 docker push <repository>/<image-name>:<tag>
```
- Uploads an image to a Docker registry.
Prune unused containers, images, networks, and volumes:
```
 docker system prune
```
- Cleans up unused resources.
- Add -a to remove all stopped containers and unused images.

These commands cover most of the typical operations when working with Docker, such as managing containers, images, and networking.
