Exploring Docker

In this step, you will embark on an exploration of Docker by pulling and running a simple container.

Pull the "hello-world" Docker image:
```
docker pull hello-world
```
Run the "hello-world" container:
```
docker run hello-world
```

Creating Your Own Container

In this step, you will create a simple Dockerfile to build your own custom Docker image.

Create a file named Dockerfile in the ~/project directory with the following content:

FROM alpine:latest
CMD ["echo", "Welcome to the Docker Arena"]

Build the Docker image from the Dockerfile:

docker build -t docker-arena .

Run the custom Docker container based on the newly-built image:

docker run docker-arena

Managing Containers

In this step, you will learn how to start, stop, and remove Docker containers.

Start a container named "nginx" using the official nginx image:
```
docker run --name nginx -d -p 8080:80 nginx
```
Stop the running "nginx" container:
```
docker stop nginx
```
Remove the "nginx" container:
```
docker rm nginx
```
