deploy not work

@arrow2012 Thank you for your report.

It seems that use are using docker-compose to run the hello service. However the deploy keyword in a compose file is reserved for the deployment of stacks in a swarm cluster (https://docs.docker.com/compose/compose-file/#deploy) and this section of the compose file is ignored when deployed with docker-compose.
Did you encounter any other error message?

Yes. yml version 3.7. docker-compose version 1.24.1, build 4667896b.
"WARNING: Some services (service_name) use the 'deploy' key, which will be ignored. Compose does not support 'deploy' configuration - use docker stack deploy to deploy to a swarm."

That is just a warning telling that docker-compose does not provide any functionality we are expecting under the deploy

Means, if you want use the deploy option you cannot just use docker-compose up -d you need to initiate the docker swarm docker init swarm and then do docker stack deploy --compose-file="docker-compose.yml" stack to start containers under docker swarm.

when use docker-compose add a parameter --compatibility,like docker-compose --compatibility up -d maybe help you!
