CKS Exam Domains

Domain 1: Cluster Setup, Maintenance, and Troubleshooting

Setting up and maintaining a Kubernetes cluster is a critical aspect of the CKS exam.

It involves configuring and managing the cluster components, such as the control plane, worker nodes, and networking.

Troubleshooting skills are also essential to identify and resolve issues that may arise during cluster operations.

To excel in this domain, candidates should have a solid understanding of Kubernetes architecture and be familiar with various deployment strategies.

They should also be proficient in using kubectl commands for cluster management and troubleshooting.

Here are some key topics covered in this domain:

• Cluster installation and configuration: This includes selecting the appropriate installation method, configuring cluster networking, and securing the cluster.
• Cluster upgrades and maintenance: Candidates should be knowledgeable about upgrading Kubernetes versions, managing node upgrades, and performing routine maintenance tasks.
• Cluster troubleshooting: This involves diagnosing and resolving common cluster issues, such as pod scheduling problems, network connectivity issues, and control plane failures.

Remember to practice hands-on exercises and explore real-world scenarios to gain practical experience in cluster setup, maintenance, and troubleshooting.

Tip: Familiarize yourself with the official Kubernetes documentation and online resources to deepen your knowledge and stay updated with the latest best practices.

Domain 2: Security Best Practices

When it comes to the CKS Exam, understanding security best practices is crucial. Protecting your Kubernetes clusters and applications from potential threats is of utmost importance.

Here are some key points to keep in mind:

• Implement RBAC: Role-Based Access Control (RBAC) allows you to define and manage permissions for users and service accounts within your cluster.
• Enable Pod Security Policies: Pod Security Policies help enforce security policies for pods running in your cluster, ensuring that only authorized containers are deployed.
• Use Network Policies: Network Policies allow you to define rules for inbound and outbound traffic to and from your pods, adding an extra layer of security.

Tip: Regularly update and patch your Kubernetes components and applications to address any known vulnerabilities.

Remember, following security best practices not only helps protect your cluster but also ensures the integrity and confidentiality of your applications.

Domain 3: Application Lifecycle Management

Application Lifecycle Management focuses on managing the deployment and lifecycle of applications running on Kubernetes clusters. It involves tasks such as creating and managing deployments, scaling applications, updating application configurations, and monitoring application health.

To effectively manage the application lifecycle, consider the following:

• Version Control: Use a version control system to track changes to application code and configurations. This allows for easy rollback and collaboration.
• Continuous Integration and Deployment: Implement CI/CD pipelines to automate the build, test, and deployment processes. This ensures consistent and reliable application deployments.
• Monitoring and Logging: Set up monitoring and logging solutions to gain insights into application performance and troubleshoot issues.

Remember to follow security best practices and consider the specific requirements of your applications when managing their lifecycle.
