Functions

Namespace

A namespace provides a method of allocating resources among multiple users. It applies to scenarios where multiple teams or projects exist.

Currently, CCI provides general-computing and GPU-accelerated resources. When creating a namespace, you must choose a resource type so that workloads you create can run in the corresponding cluster.

For more information, see Creating a Namespace.

Workload

A workload is an application running on Kubernetes. No matter how many components are there in your workload, you can run them in a group of Kubernetes pods. A workload is an abstract model of a group of pods in Kubernetes. There are different types of workloads, such as Deployments, StatefulSets, DaemonSets, jobs, and CronJobs.

CCI provides Kubernetes-native container deployment and management and supports lifecycle management of workloads, including creation, configuration, monitoring, auto scaling, upgrade, deletion, service discovery, and load balancing.

For more information, see Deployments, Pods, Jobs, and CronJobs.

Workload Exceptions

When a workload is abnormal, you are advised to view events first.

On the workload details page, if an event is displayed indicating that the container fails to be restarted or the image fails to be pulled, you can follow the instructions to locate the fault.

For more information, see What Do I Do If an Event Indicating That the Image Failed to Be Pulled Occurs? and What Do I Do If an Event Indicating That the Container Failed to Be Restarted Occurs?

Network Access

By deeply integrating the Kubernetes networking capabilities with Huawei Cloud Virtual Private Cloud (VPC), CCI provides stable and high-performance container networking for mutual access of workloads in complex scenarios.

Workloads can be accessed over a private network or public network and can access the public network.

For more information, see Network Access Overview, Private Network Access, Public Network Access, and Access to a Public Network from a Container.

Container Storage

Container storage provides storage for workloads. It supports multiple StorageClasses. A pod can use any amount of storage.

Data can be stored in volumes provided by Huawei Cloud storage services, including Elastic Volume Service (EVS), and SFS Turbo.

For more information, see EVS Volumes, and SFS Turbo Volumes.

Add-on Management

Add-ons extends existing features. You can directly install the add-ons and use the functions provided by the add-ons conveniently.

CCI provides the CoreDNS add-on, which provides the internal domain name resolution for workloads. You are advised not to delete or upgrade this add-on, or the internal domain name resolution will become unavailable.

For more information, see CoreDNS Add-on Management.

Log Management

CCI allows you to mount a storage volume for log collection. To write logs to the log storage volume, you only need to mount this volume when you create a workload.

CCI is interconnected with Application Operations Management (AOM), which collects and dumps the .log files in container log storage.

For more information, see Viewing Logs.

Permissions Management

CCI allows you to grant permissions to your IAM users and user groups. It combines the advantages of Kubernetes Role-based Access Control (RBAC) authorization and Identity and Access Management (IAM) to provide a variety of authorization methods, including IAM fine-grained authorization, IAM token authorization, namespace-level authorization, and namespaced resource authorization.

For more information, see CCI Permissions, Creating a User and Granting Permissions, and Granting Namespace Permissions to a User or User Group.
