# Services

{% hint style="info" %}
The **Services** menu is only available to Docker Swarm endpoints.
{% endhint %}

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](https://docs.portainer.io/2.33-lts/user/swarm/setup#other) 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.

For more on how this works, have a look at [this article](https://docs.portainer.io/2.33-lts/faqs/troubleshooting/stacks-deployments-and-updates/how-does-the-image-update-notification-icon-work).

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.
