Parameter | Support Details | Description |
Model | Standard: S2, S4, S5, SA2, SA3, S6, SA5, SA4, S7, and S8 Compute optimized: C3, C4, C5, and C6 Memory optimized: M3, MA3, M5, and M6 GPU optimized: GN7, GNV4, PNV4, GN10X, GN10Xp, and GT4 High-IO type: IT5 | The models displayed in the console vary with the remaining resources in the selected availability zone. If you need other models, you can submit a ticket to seek for help. Moreover, native node pools support several alternative models with the same specifications. You can go to the node pool details page to configure. |
System disk | Premium Cloud Disk and SSD | It is recommended that the system disk be at least 100 GB. |
Data disk | Premium Cloud Disk, SSD, Balanced SSD, and Enhanced SSD | It is recommended that the data disk be at least 50 GB. By default, no data disk is bound. |
Public network bandwidth | EIP binding is supported. | By default, the node's public network bandwidth is not enabled. For details, see Enable the Public Network Access. |
Operating system | TencentOS Server | Based on the Tencent Cloud virtualization platform, by using techniques such as kernel optimization, the operating system supports cloud-native resource isolation and performs comprehensive parameter tuning for container applications. |
Node login | SSH login | By default, node login is enabled. You can enable and distribute an SSH key in the console for the node to be logged in. For details, see Enable SSH Key Login. |
GPU driver | Drivers 450/470/515/525 | When creating a node pool, you can select the target driver below model selection. |
Runtime | Only Containerd is supported. | For Kubernetes clusters 1.16 and later versions, the supported Containerd version is 1.6.9. |
Kubernetes | K8s major version 1.16 or later | Some K8s versions have specific minor version requirements including: v1.16.3-tke.28 or later; v1.18.4-tke.26 or later; v1.20.6-tke.21 or later. |
Operation and Maintenance Parameters | The setting of parameters for Kubelet, Kernel, Hosts, and Nameservers is supported. | |
Initialization Script | Two phases are supported: before node initialization and after node initialization. | You can provide an initialization script when creating a node pool. |
Node Auto Scaling | Supported. | |
Node Specification Enlargement | Supported. A scalable dedicated scheduler for native nodes is provided. | |
qGPU | Supported. | |
Memory Compression | Supported. | For details, see the Memory Compression User Guide. |
Preemptible Jobs | Supported. | For details, see the preemptible Job feature description. |
QoSAgent | Supported. | Multi-dimensional fine scheduling capabilities such as CPU Priority, CPU Burst, Memory/Network/Disk IO QoS enhancements are provided, improving cluster resource utilization while ensuring quality stability. For details, see Fine Scheduling. |
Fault Self-Healing | Supported. | Based on TKE's self-developed intelligent operations product Cloud Explorer, it provides multi-dimensional fault self-healing capabilities, comprehensively enhancing node stability and improving operational efficiency. For details, see Fault Self-Healing Rules. |
In-Place Scaling | Supported. |
