You can make changes to your environment's Kubernetes configuration by selecting Cluster from the menu then selecting Setup.
To use this feature, you need to ensure that your cloud provider allows you to create load balancers. Using this feature may incur costs from your cloud provider.
Enabling the load balancer feature will allow users to expose applications they deploy over an external IP address assigned by their cloud provider.
Configuring ingress controllers will allow users to expose applications they deploy over a HTTP route.
Portainer auto detects and lists any ingress controllers defined in the cluster and sets them to allowed by default. As an admin you may choose to disable ingress controllers as needed.
Enabling Allow Ingress class to be set to "none" will let users create ingress objects without specifying any Ingress Class. This is useful for Kubernetes implementations where there is no
IngressClassdefined in the cluster.
Enable the Configure ingress controller availability per namespace toggle to be able to control Ingress Class availability further at the namespace level.
Enabling Only allow admins to deploy ingresses restricts the deployment of ingresses to cluster administrators only, preventing standard users from creating new ingresses.
If this setting is enabled and an update is made to an application outside of this window, it will not be applied.
This section allows you to override any global deployment options set for Kubernetes environments.
By default, a Kubernetes cluster will instantiate a default namespace when provisioning the cluster to hold the default set of pods, services, and deployments used by the cluster. If this option is enabled, the only users with the power to run applications in the default namespace are Portainer administrators.
Enabling this feature lets you allocate more resources to namespaces than are physically available in the cluster.
Enable resource over-commit if you need to assign more resources to namespaces than are physically available in the cluster. This may lead to unexpected deployment failures if there are insufficient resources to meet the demand.
Disable resource over-commit (highly recommended) if you are only able to assign resources to namespaces that are less (in aggregate) than the cluster total, minus any system-resource reservation.
Enabling this feature will allow users to use specific features that leverage the metrics API component, such as the memory and CPU usage graphs at the cluster and node level. If Portainer detects you are using a metrics server and is able to connect, this will default to on.
Select which storage options will be available for use when deploying applications. Take a look at your storage driver documentation to figure out which access policy to configure, and whether or not the volume-expansion capability is supported. Any storage classes marked as default will be automatically set to on.
