How to scale a service
In this help article, you will learn how to scale your services. This is a powerful feature because, in no time, Portainer allows you to scale your services horizontally.
Once you logged in Portainer, do a click in Services and then do a click in Scale.
Enter the number of replicas you want for this service and click on the Check button.
If everything works as expected, you will see the following pop up.
After a few seconds (depends on the size of the container), you can refresh this page, and you will see (as this case) three replicas running.
