How to remove docker container using port number - shell

Question

I have Node services which are running in Docker container
I am using shell script to run these services
I want to run three different instances of the same service on 3 different port. say 9011 9022 9033
I also want it to configure it in such a way that after every new deployment it should stop the previous service and remove it
I am using docker rm test-service to remove it but it will remove other instances too.
by this approach only once instance can be running.
Is there any way to remove Docker service running on the specific port.
here is my shell script
#!/bin/bash
ORGANISATION="$1"
SERVICE_NAME="$2"
VERSION="$3"
ENVIRONMENT="$4"
INTERNAL_PORT_NUMBER="$5"
EXTERNAL_PORT_NUMBER="$6"
NETWORK="$7"
docker build -t ${ORGANISATION}/${SERVICE_NAME}:${VERSION} --build-arg PORT=${INTERNAL_PORT_NUMBER} --build-arg ENVIRONMENT=${ENVIRONMENT} --no-cache .
docker stop ${SERVICE_NAME}
docker rm ${SERVICE_NAME}
sudo npm install
sudo npm install -g express
docker run -p ${EXTERNAL_PORT_NUMBER}:${INTERNAL_PORT_NUMBER} --network ${NETWORK} --name ${SERVICE_NAME} --restart always -itd ${ORGANISATION}/${SERVICE_NAME}:${VERSION}

Answer 1

I can not run more than one container with the same name. Can I run the docker service with the same name on 3 different port. if yes what modifications do i need to make in above shell file?
That would be three docker run, each using the same internal port, but mapped to a different host port, with three different names
docker run -p ${EXTERNAL_PORT_NUMBER1}:${INTERNAL_PORT_NUMBER} --name ${SERVICE_NAME1}
docker run -p ${EXTERNAL_PORT_NUMBER2}:${INTERNAL_PORT_NUMBER} --name ${SERVICE_NAME2}
docker run -p ${EXTERNAL_PORT_NUMBER3}:${INTERNAL_PORT_NUMBER} --name ${SERVICE_NAME3}
I want to perform LoadBalance for service
See docker swarm mode
The swarm manager uses ingress load balancing to expose the services you want to make available externally to the swarm.
The swarm manager can automatically assign the service a PublishedPort or you can configure a PublishedPort for the service. You can specify any unused port. If you do not specify a port, the swarm manager assigns the service a port in the 30000-32767 range.
Example:
the following command publishes port 80 in the nginx container to port 8080 for any node in the swarm
$ docker service create \
--name my-web \
--publish 8080:80 \
--replicas 2 \
nginx
