Once a VM name is altered on the ECS console, the node name cannot be modified accordingly during ECS synchronization. To prevent conflicts between Kubernetes node names, a suffix is automatically added to the node name of a node configured with cceNodeName.
Parameter Example Description Node Type Elastic Cloud Server (VM) Select a node type based on service requirements. The available node flavors will then be displayed in the Specifications area for you to choose from.
Log in to the ECS where kubectl has been installed. Create a description file named wordpress-deployment.yaml. wordpress-deployment.yaml is an example file name.
Formula: Memory usage = Used memory on all nodes/Total memory on all nodes × 100% Cost Breakdown Cost breakdown during the specified time period, including the ECS cost, EVS cost, and CCE cluster management cost.

Install kubectl on an existing ECS and access the cluster using kubectl. For details, see Accessing a Cluster Using kubectl.
Check whether the Kubernetes node name is the same as the ECS name. 2 Upgrade Management Check whether the target cluster is under upgrade management. 3 Add-ons Check whether the add-on status is normal.
Dynamic Adjustment of the Weight of the Backend ECS Table 6 Annotations for dynamically adjusting the weight of the backend ECS Parameter Type Description Supported Cluster Version kubernetes.io/elb.adaptive-weight String Dynamically adjust the weight of the load balancer backend
For example, if an IAM user wants to query ECSs using an API, the user must have been granted permissions that allow the ecs:servers:list action. Supported Actions CCE provides system-defined policies that can be directly used in IAM.
Changing the flavor of a node in a node pool on the ECS console If a node flavor is different from the flavor specified in the node pool where the node resides, the increased number of nodes in a node pool scale-out is different from the expected number.
Figure 1 Execution process of the case Install kubectl on an existing ECS and access a cluster using kubectl. For details, see Accessing a Cluster Using kubectl.
Whether 90% or more of the ECS quota has been used Yes Pod Diagnosis Items and Rectification Solutions Table 1 Pod diagnosis items and rectification solutions Diagnosis Item Rectification Solution FailedScheduling Insufficient memory The available memory of the node is insufficient

Subnet CIDR Block A subnet is a network that manages ECS network planes. It supports IP address management and DNS. ECSs in a subnet are assigned IP addresses from this subnet.
Remote CCE Turbo Cluster Cloud resources are categorized into two main types based on deployment location, service scope, and functions: Central cloud resources: deployed in large data centers to provide global, highly elastic, and full-featured cloud computing services, such as ECS
If no EIP is bound to the node during node creation, you can manually bind one on the ECS console after creating the node. Install add-ons for the cluster. autoscaler: node scaling add-on metrics-server: an aggregator of resource usage data in a Kubernetes cluster.
Configuring resource quotas for cloud services: Cloud services like ECS, EVS, VPC, ELB, and SWR are also used to run the CCE clusters. If the existing resource quotas cannot meet your requirements, submit a service ticket to increase the quotas.
Figure 4 Checking the IP address of a DCS Redis instance Install kubectl on an existing ECS and access a cluster using kubectl. For details, see Accessing a Cluster Using kubectl. Create a secret for JuiceFS to access the OBS bucket and DCS Redis instance.
