Must-Read Before Use
Note: Resources such as Virtual Machines, Disks, EIPs, etc., created via UK8S should not be deleted from specific product list pages, as it may lead to abnormal operation of UK8S or risk of data loss. You can release or unbind resources via UK8S to delete them.
UK8S provides orchestration and scheduling capabilities for container applications running on IAAS class products of UCloud Global, such as UHost, UDisk, EIP, ULB, etc. To help you use UK8S better, you need to understand and agree:
-
You need to authorize UK8S to manage certain products to take advantage of other products of UCloud Global when operating clusters. For example, when creating a PVC, the cluster can help you create a UDisk.
-
UK8S does not charge a service fee. However, resources like EIP and UDisk created through the cluster will incur associated costs. For more details, refer to UK8S Pricing.
-
You can view the infrastructure components of a UK8S cluster, such as UHost, UDisk, etc., on the cluster management page. Please refrain from altering or deleting these resources from other product list pages.
-
UK8S product versions follow the cloud-native Kubernetes versions. By default, UK8S supports the three latest versions (see recommendations). Users are advised to upgrade older versions, otherwise some functions may not be available.
Do Not Arbitrarily Operate Resources Created by UK8S
UK8S will create a batch of cloud resources on your behalf, such as UHost, UDisk, etc. These cloud resources are the infrastructure that UK8S clusters rely on. Once changed, it may have unpredictable impacts on cluster operations. Please do not modify them arbitrarily.
How to identify cloud resources created by UK8S?
The names of cloud resources created by UK8S follow a clear naming convention. For more details, refer to Naming Convention. A brief description is as follows:
-
UHost Name: [cluster-id]-[nodetype]-[randomcode]. For example, the VM whose name is “uk8s-uxl1l3l0-n-4rd91”, is the Node of the UK8S cluster “uk8s-uxl1l3l0”.
-
ULB Name: [cluster-id]-[master]-ulb. For example, the ULB named “uk8s-uxl1l3l0-master-4rd91” is the internal network ApiServer entrance. Do not delete it.
Avoid Deploying Business on Master Nodes
The 3 Master nodes in the UK8S cluster have pre-deployed k8s management services, and the nodes have been set to SchedulingDisabled. It is not recommended to schedule your own business on the Master nodes.
