💡 Hint

Common Mistakes

Using 'docker build' instead of 'docker run'.

Using 'docker pull' which only downloads the image but does not run it.

The docker run command starts a container from an image. Here, it runs the hello-world image to verify Docker is installed correctly.

💡 Hint

Common Mistakes

Using 'docker run' when the task asks to pull the image only.

Using 'docker exec' which runs commands inside a running container.

The docker pull command downloads the image from Docker Hub without running it. This is useful to get the image first.

💡 Hint

Common Mistakes

Typing 'runs' instead of 'run'.

Using 'start' which is for starting stopped containers, not running new ones.

The correct command is docker run. Using 'runs' or 'running' is invalid syntax and causes an error.
