How to run a Docker image?

To run a Docker image, you can use the docker run command followed by the name of the image. Here’s the general syntax:

docker run <image_name>

For example, to run the official hello-world image, you would execute:

docker run hello-world

If you want to run the container in the background (detached mode), you can add the -d flag:

docker run -d <image_name>

Additionally, if you need to map a port from the container to your host machine, you can use the -p option. For example, to run an image and map port 3000 of the container to port 3000 on your host, you would use:

docker run -p 3000:3000 <image_name>

Replace <image_name> with the name of the image you want to run.
