Cluster Overview By using the Cluster technology, you receive considerabe benefits in terms of performance, reliability, and flexibility at an affordable cost. Task scheduling is central to a cluster system.
Cluster Lifecycle This section describes the status of each cluster lifecycle, helping you understand the running status of the cluster in different phases.
Creating a Hybrid Cluster On the CCE console, you can easily create Kubernetes clusters. Kubernetes can manage container clusters at scale. A cluster manages a group of node resources. A hybrid cluster can manage VMs, physical machines (PMs), or a combination of both.
Creating a BMS Cluster Bare metal server (BMS) clusters are Kubernetes container clusters with high computing and high network performance. To use a BMS cluster, enable the BMS service first.
Upgrading a Cluster Kubernetes versions are expressed as x.y.z, where x is the major version, y is the minor version (for example, v1.13), and z is the patch version. Minor releases occur approximately every 3 months to provide new features, design updates, and bug fixes, and each minor release branch is maintained for approximately 9 months. You can use the CCE console to upgrade your cluster to the latest Kubernetes version or a bug fix.
Cluster Auto Scaling The Cluster Auto Scaling feature allows CCE to automatically scale out a cluster (add nodes to a cluster) according to custom scale-up policies when workloads cannot be scheduled into the cluster due to insufficient cluster resources.
Monitoring a Cluster CCE is seamlessly integrated with the Cloud Eye service on HUAWEI CLOUD. You can learn the resource usage and monitoring metrics of clusters' master nodes in real time and receive alarms immediately upon detecting an anomaly.
Namespace A namespace is a collection of resources and objects. Multiple namespaces can be created in a single cluster, but they are isolated from each other. This enables namespaces to share the services of the same cluster without affecting each other.
Cluster Management Permission Control To perform permission control on resources in a cluster (for example, user A can only read and write applications in a namespace, while user B can only read resources in a cluster), perform the operations described in this section.
