What is the basic difference between the running and starting of a Docker container

Question

I am new to docker and its concept. Can anyone help me with some commands?

Since I have used the below command:

docker run -it container_id 

It creates a new container. In that case, what will the below command do.

docker start

I know this is a very basic query. Can anyone resolve this query?

Thanks.

Here is the basic difference between run and start command.

Run command is used to create a new container of an image, and execute the container. You can create N clones of the same image. The command is: docker run IMAGE_ID and not docker run CONTAINER_ID

Start command It is used to Launch a container previously stopped. Such as, if you had stopped a database with the command docker stop CONTAINER_ID, you can relaunch the same container with the command docker start CONTAINER_ID, and the data and settings will be the same.

I hope it would resolve you query.
