Unable to access service running in docker swarm cluster

I have a docker swarm cluster with following nodes

NAME       ACTIVE   DRIVER       STATE     URL                         SWARM   DOCKER      ERRORS
manager1   -        virtualbox   Running   tcp://192.168.99.113:2376           v19.03.12   
worker1    -        virtualbox   Running   tcp://192.168.99.114:2376           v19.03.12   
worker2    -        virtualbox   Running   tcp://192.168.99.115:2376           v19.03.12

I have created service on manager node as follows

$ docker service create --name registry --publish 5000:5000 registry:2

Now I can access the service from any swarm node

$ curl localhost:5000/v2/_catalog                                     
{"repositories":[]}

But If I try to access the service from outside swarm cluster I get this error

$ curl localhost:5000/v2/_catalog
curl: (7) Failed to connect to localhost port 5000: Connection refused

How can we access service running in swarm cluster from host machine

Solution

  • Finally I was able to access service with this command curl <manager/worker ip>:5000/v2/_catalog
