The Services menu is only available to Docker Swarm endpoints.
A service consists of an image definition and container configuration as well as instructions on how those containers will be deployed across a Swarm cluster.
When the new image indicator feature is enabled, the Images up to date column indicates whether the local images in the service are up to date, with a green tick indicating they are up to date and an orange cross indicating that there is a newer version of an image available at the remote registry. A grey hyphen indicates Portainer was unable to determine whether there is an update available for the images.
You can click the Reload image indicators button to recheck the images for all your services for updates, or to recheck a single service's images you can click the image indicator icon for that service.

Once a service has been created you can scale it to meet your needs, as well as view individual task status and logs.
If you need to undo some changes to a service, you can roll it back.
You can also configure webhooks for your services.
