To run our first Docker image terryalsdorf/devopshelloworld:latest, follow these steps:

Pull the Docker Image

First, you need to pull the Docker image from the Docker Hub repository to your local machine. You can do this using the docker pull command:

docker pull terryalsdorf/devopshelloworld:latest

Run the Docker Container

Once you have the image locally, you can run it as a Docker container using the docker run command:

docker run -d -p 8080:80 terryalsdorf/devopshelloworld:latest

-d: Runs the container in detached mode (in the background).

-p 8080:80: Maps port 8080 on your host to port 80 in the container.

Access the Application

Now that the container is running, you can access your application by opening a web browser and navigating to http://localhost:8080. You should see the "Hello, World!" message from your Docker container.

Stop and Remove the Container

When you're done testing, you can stop and remove the container using the following commands:

docker stop <container_id>

docker rm <container_id>

Replace <container_id> with the actual ID or name of the running container. You can find the container ID by running docker ps

That's it! You've successfully run your first Docker image as a container.
