Kubermatic Kubernetes Platform supports a multitude of different cloud providers. In order to ensure the best integration possible Kubermatic has a tiered approach towards the providers.Currently supported are the following infrastructures and cloud providers:
Tier 1
Tier 2
Tier 3
Note: KubeVirt cloud provider is under heavy development. There is no guarantee that user clusters created on the KubeVirt cloud provider will perform well after the upgrade to the newer KKP version.
Please note that the vendors of the software or the cloud provider may change functions or features on their own accord. Kubermatic does not guarantee any particular compatibility with a certain feature. Tier 1 has full support of the providers capabilities (but only up to our knowledge), these providers are included in our regular end-to-end tests. Tier 2 has the support for all needed functions that are consumed, but some deeper integrations might not be available. Tier 3 means that it works for the stated releases but we do not do extensive end to end tests.
See detail pages for specific requirements of the cloud providers.
Some cloud providers supported by the Kubermatic Kubernetes Platform support periodic reconciliation of cloud infrastructure resources created by KKP (for example, subnets or firewall/security group rules). KKP uses a timestamp in LastProviderReconciliation on the cluster status to trigger a reconciliation after the cluster was set up initially. This defaults to six hours and can be changed on a datacenter level by setting ProviderReconciliationInterval.
Currently, KKP periodicially reconciles the following providers:
