How to get container id of a docker service

Question

I want to get a container ID of docker service. Is there any command available for this ?

I tried

docker service ps MyService

but this one only gives the service ID, I am interested in the container id in which the service is running

Answer 1

try combination of docker process filtering and formatting:

docker ps -f name=YOUR_SERVICE_NAME --format "{{.ID}}"

UPDATE

thanks to ahivert for even shorter solution:

# same behavior with
docker ps -f name=YOUR_SERVICE_NAME --quiet

Answer 2

try from

https://github.com/moby/moby/issues/31369

for f in $(docker service ps -q $service);do docker inspect --format '{{.NodeID}} {{.Status.ContainerStatus.ContainerID}}' $f; done

and

docker network inspect --verbose
