What is UK8S?

SurferCloud UK8S is a fully managed Kubernetes service designed for both developers and enterprises to quickly and easily deploy containerized applications. UK8S abstracts away the complexity of setting up and maintaining Kubernetes clusters, allowing users to focus on their applications without worrying about infrastructure management. The platform is fully compatible with Kubernetes' native API, ensuring a seamless experience for developers accustomed to the community Kubernetes environment.

Key Features and Advantages of UK8S

1. Automated Cluster Deployment and Management

With UK8S, users can create and manage Kubernetes clusters in just 5 minutes. The service supports dynamic scaling, allowing users to add or remove worker nodes as needed. This automation eliminates the need for manual intervention in cluster management, making it easier to get started with Kubernetes in the cloud.

2. Deep Integration with UCloud Cloud Products

UK8S integrates tightly with SurferCloud's suite of cloud products, such as UDisk, ULB, EIP, and VPC. These integrations allow users to leverage powerful cloud resources without managing them separately. For instance, when creating a Persistent Volume Claim (PVC) within the Kubernetes environment, UK8S will automatically provision the necessary UDisk (block storage).

3. High Availability for Critical Applications

UK8S ensures business continuity by offering 3 Master Node high availability. It also supports cross-availability zone deployments for nodes and applications, ensuring your workloads remain available even during infrastructure disruptions. This architecture guarantees that your services can continue running without interruption, a critical feature for enterprise-level applications.

4. Full Compatibility with Native Kubernetes APIs

UK8S is fully compatible with the native Kubernetes APIs, offering multi-version support. The platform closely follows the Kubernetes community’s release cycle, ensuring that your workloads can benefit from the latest features and improvements. Whether you are running a legacy application or a cutting-edge service, UK8S ensures compatibility with the Kubernetes ecosystem.

5. Private Cluster Control

UK8S provides complete isolation between different users' clusters, ensuring tenant segregation and transparency in terms of resource usage. Cluster resources are visible only to the authorized users, and users have full control over their private cluster configurations.

Why Choose UK8S Over DIY Kubernetes Clusters?

1. Simplified Cluster Management

Unlike setting up a self-managed Kubernetes cluster, UK8S offers one-click cluster creation, reducing the time spent on configuration and management. Whether you're using cloud-native resources like UHost (cloud servers) or UDisk (block storage), UK8S automatically handles the orchestration.

2. Built-in Cloud Resource Integration

With UK8S, you no longer have to manually integrate various cloud products. UK8S leverages the SurferCloud ecosystem, such as UDisk for persistent storage, ULB for load balancing, and EIP for elastic IP allocation. This deep integration streamlines your Kubernetes management, making it easier to scale applications and manage cloud resources.

3. High Availability & Fault Tolerance

UK8S' high availability architecture ensures that your applications are fault-tolerant, preventing downtime caused by node or network failures. The service automatically balances workloads and maintains the health of your cluster without manual intervention.

4. Transparent Pricing

UK8S charges no service fees. You only pay for the cloud resources you use, including cloud hosts (UHost), cloud disks (UDisk), load balancers (ULB), and elastic IPs (EIP). This pricing model ensures that you only pay for what you use, without hidden costs for Kubernetes management.

How to Use UK8S

1. Resource Management

Once you create a Kubernetes cluster with UK8S, it will automatically provision the necessary cloud resources (e.g., UHost, UDisk, EIP, etc.). Please note that these resources are tied to the UK8S cluster and should not be modified or deleted manually. Doing so may disrupt the operation of your cluster or result in data loss.

2. Node and Application Management

It’s essential to avoid deploying business workloads on Master nodes, as these nodes are reserved for managing the Kubernetes control plane and are set as SchedulingDisabled. For optimal performance, deploy applications on the Worker nodes, which handle actual workload scheduling and execution.

3. Cluster Upgrades and Maintenance

UK8S supports the latest Kubernetes versions, and the platform encourages users to upgrade to the most recent versions to take advantage of new features and improvements. Running outdated Kubernetes versions could limit your access to certain functionalities, so it's important to stay up-to-date.

4. Monitoring and Logging

UK8S provides users with a web terminal and a graphical management interface for easy cluster monitoring and management. These interfaces allow you to track the health of your cluster, manage resources, and monitor application performance.

Important Considerations

• Avoid Modifying UK8S-created Resources: To ensure smooth operation, do not delete or modify cloud resources like UHost, UDisk, or EIP directly from the product interface. Always use UK8S to manage and release resources.
• Master Node Restrictions: Avoid deploying your business applications on the Master nodes to ensure your services are isolated from cluster management activities.
• Cluster Versions: UK8S supports the three most recent Kubernetes versions. Make sure to upgrade your clusters regularly to stay on the supported version and take full advantage of Kubernetes' latest features.

Conclusion: Simplifying Container Management with UK8S

SurferCloud UK8S offers a powerful yet simple solution for managing containerized applications. By abstracting away the complexities of Kubernetes cluster setup and maintenance, UK8S allows developers and businesses to focus on their applications, while SurferCloud handles the heavy lifting. With features like high availability, deep integration with cloud products, and seamless compatibility with Kubernetes APIs, UK8S is the ideal choice for businesses looking to modernize their infrastructure and scale applications in a cloud-native environment.

Frequently Asked Questions and Answers

Q1: Does UK8S support custom network plugins?
A1: UK8S is compatible with SurferCloud VPC’s high-performance network plugin, and users can integrate other supported network plugins. However, it is not recommended to change the network plugin configuration arbitrarily, as it may affect the stability of the cluster.

Q2: How can I add nodes to a UK8S cluster?
A2: In the UK8S console, users can add nodes with a one-click operation. The system will automatically configure the required resources and add them to the cluster. You can dynamically add or remove worker nodes based on your actual needs.

Q3: How does UK8S ensure high availability of the cluster?
A3: UK8S ensures high availability of the cluster through a 3-Master node high-availability architecture and cross-availability-zone deployment. If a node or zone fails, the system will automatically reroute traffic to healthy nodes or zones, ensuring business continuity.

Q4: Do I need to manage the storage for the cluster myself?
A4: No, you do not need to. UK8S automatically creates and manages storage resources, such as UDisk block storage, UFS file storage, and US3 object storage. When you create a Kubernetes application, UK8S will automatically configure the required storage resources.

Q5: How do I upgrade the Kubernetes cluster version?
A5: Users can check the current version of the cluster in the UK8S console and upgrade as needed. UK8S supports the latest versions released by the Kubernetes community and provides upgrade guides to help users transition smoothly.

Q6: Does UK8S support integration with other cloud platforms?
A6: UK8S is primarily integrated with SurferCloud products such as UHost, UDisk, ULB, EIP, etc. However, users can integrate with other cloud platforms based on their needs through Kubernetes’ standard API.
