For example, CCE can be interconnected with block storage (EVS), file storage (SFS), and object storage (OBS) services. Basic Objects in Kubernetes The following figure shows the basic objects in Kubernetes and the relationships between them.
everest-csi-provisioner 17d # Storage class for EVS disks with delayed association csi-nas everest-csi-provisioner 17d # Storage class for SFS file systems csi-obs everest-csi-provisioner 17d # Storage class for OBS
CCE Tenant Guest Monitoring Center and Alarm Center check the configurations of global resources (for example OBS or DNS) associated with clusters to identify invalid or inappropriate configurations.
StorageClass: EVS, SFS, SFS Turbo, OBS, DSS, local PV, and EV are provided. For details, see Storage Overview. Auto scaling Workload scaling: The number of workload pods can be adjusted based on service requirements and policies. For details, see Workload Scaling Rules.
TCP port 443 100.125.0.0/16 Allow the worker nodes to access OBS over internal networks to pull the installation package. TCP port 6443 100.125.0.0/16 Allow the worker nodes to report that the worker nodes have been installed. Parent Topic: Network Planning
Clearing Idle Resources in a Timely Manner It is a good option to identify and clear idle cloud services or resources in clusters in a timely manner, such as unused ECSs, EVS disks, OBS buckets, ELB load balancers, and EIPs.
When assigning this role to a user group, you must also select other roles and policies on which this role depends, such as Tenant Guest, Server Administrator, ELB Administrator, OBS Administrator, SFS Administrator, APM FullAccess, and SWR Admin.
Notes and Constraints The DNS configuration of a subnet where a node is located cannot be modified because OBS and other dependent services are necessary for creating nodes.
Expanding a PVC Cloud storage: OBS and SFS: There is no storage restriction and capacity expansion is not required. EVS: You can expand the capacity of automatically created pay-per-use volumes on the CCE console.
