How to run a command inside a Docker container?

To run a command inside a Docker container, you can use the docker exec command followed by the name or ID of the container and the desired command. For example:

docker exec my_container ls -la

This command will run the ls -la command inside a running container called my_container. The -it option can be used to access the container’s interactive terminal if needed. Note that the container must be running for the docker exec to work. For more information, refer to the Docker documentation on docker exec.
