The difference between docker run and start

The difference between docker run and start

The difference between run and start in docker

Docker run specifies a mirror image.

And docker start specifies a container

Docker run uses the image to generate a container and start the container, while Docker start starts a previously generated container.

try

Docker start starts a container that has already been created.

For example, my docker has a mirror of the springboot project

Then I use the docker run command to start it. Using docker ps, I can see that a springboot container has been started, and then we stop it (docker stop)

Then use docker start to start it, and then use docker ps to see that the previously stopped one has started.

Supplement: Docker container start | restart | stop

Recently, when maintaining the Fabric network, a server power outage occurred. Except for the containers of Kafka and Zookeeper, all other containers were in the Exited state.

Ok, I need to restart the container

1. docker start

Start one or more stopped containers

docker start [OPTIONS] CONTAINER [CONTAINER...]
#You can start the container according to the container's Name or ID $ docker start ID/NAME

Options:
# -a parameter connects to the container and prints output or errors -a, --attach Attach STDOUT/STDERR and forward signals 
# I don't understand the parameters...
   --detach-keys string Override the key sequence for detaching a container
# -i parameter starts the container and enters interactive mode -i, --interactive Attach container's STDIN

2. docker restart

Restart the container, regardless of whether it was previously started or stopped

docker restart [OPTIONS] CONTAINER [CONTAINER...]
#You can restart the container according to the container's Name or ID $ docker restart ID/NAME

Options:
# -t parameter wait time before stopping the container (default 10 seconds)
 -t, --time int Seconds to wait for stop before killing the container (default 10)

3. docker stop

Stop a running container

docker stop [OPTIONS] CONTAINER [CONTAINER...]
#You can stop the container according to the container's Name or ID $ docker restart ID/NAME

Options:
# -t parameter wait time before stopping the container (default 10 seconds)
 -t, --time int Seconds to wait for stop before killing it (default 10)

With these commands, it is convenient to restart the stopped container.

Another point to note is that the chaincode container in the Fabric network does not need to be restarted using the above command. After the started peer node uses the query command to query, the chaincode container will be automatically started.
