To start a Docker container, you can use the docker start command followed by the container ID or name:
docker start <container_id_or_name>
This command restarts a stopped container, using the same options that were used to start it initially.
If you want to start a new container from an image, you can use the docker run command instead:
docker run <image_name>
This command creates and starts a new container from the specified image. You can also specify additional options, such as port mappings, volumes, and environment variables, to customize how the container is created and started.
Note that if the image has not been downloaded yet, Docker will first attempt to download it from the registry before creating and starting the container.
