The difference between run and start in dockerDocker 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. tryDocker 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.

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 startStart 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 restartRestart 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 stopStop 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. You may also be interested in:
