From the menu select Services then select the service you want to configure.
In this section you can:
View a summary of the details about the service.
Configure the number of replicas.
Here you can replace the container image with a different image. Select the registry, enter the image name, then click Apply changes.
You have the option to either mount or bind volumes in Portainer, and you can also make them read only. To add a mount, first select either Volume or Bind from the Type dropdown.
Select the volume from the Source dropdown, enter the container path in the Target field tick Read only if required then click Apply changes.
Enter the source path in the Source field, enter the container path in the Target field, tick Read only if required then click Apply changes.
You can define one or more networks for a service either before or after deployment. Simply select the network from the dropdown then click Apply changes.
Use this setting to publish ports so they can access a container from outside of the host. You can either add new ports or update existing ports.
Lets you manually specify a hostname or URL and associate the URL to an internal or external IP address.
Sets limits on resource utilization, such as memory, CPU reservation and CPU limit.
Use placement constraints to control which nodes a service can be assigned to.
While placement constraints limit the nodes a service can run on, placement preferences attempt to place tasks on appropriate nodes in an algorithmic way (by default they are spread evenly).
Docker's restart policies ensure that linked containers are restarted in the correct order, and control the conditions under which they are restarted:
Any: Restart the container under any conditions (restarted host or Docker daemon).
On Failure: Restart the container if it exits due to an error which manifests as a non-zero exit code.
None: Do not automatically restart the container.
You can also adjust the restart delay, maximum attempts and restart window.
Normally, updating a service will only cause the service’s tasks to be replaced with new ones if a change to the service requires recreating the tasks for it to take effect.
Docker includes logging mechanisms called logging drivers that get information from the containers and services you're running. Each Docker daemon has a default logging driver which each container will use, unless you configure them to use a different logging driver.
Lets you add metadata to containers using Docker labels either via an array or a dictionary. We recommend that you use reverse-DNS notation to stop labels from conflicting with those used by other software.
Docker 17.06 introduced Swarm service configs. These allow you to store non-sensitive information such as configuration files outside a service’s image or running containers. This keeps images as generic as possible and removes the need to bind-mount configuration files into containers or use environment variables.
In the context of Docker Swarm services, a secret is a blob of data such as a password, SSH private key, SSL certificate, or another piece of data that should not be transmitted over a network or stored unencrypted in a Dockerfile or in your application’s source code.
Toggle the on or off.

Update, or delete the service.
It's best to set environment variables when you and before deployment. You can still set or edit these variables after deployment if you wish.
Labels give you a way to record information about a container, such as the way it's configured. Labels can also be used by Portainer to .
Updates a service according to the parameters you specify. The parameters specified here are the same as docker service create (see for more information).
