10 Kubernetes Best Practices in DevOps — without ChatGPT>
– Stephen Chin
1.
Reduce Complexity: Kubernetes simplifies complex system operations by grouping together similar services and applications into manageable groups called “Namespaces”.
Try to keep your namespaces simple, clean, and as modular as possible.
This will make it easier to debug and update.
2.
Modular Volumes: Volumes in Kubernetes should be modular, so that the components within the same namespace are located on the same volume.
This will help make troubleshooting easier and ensure that components of the same namespace are operating as expected.
3.
Simplify Logging: Make sure that all of your containers are outputting logging information in an organized manner.
This will make troubleshooting and debugging much easier.
4.
Automate Deployments: Deployment automation can be a life saver in difficult debugging situations.
Make sure to always have an automated process to handle deployments and ensure that you apply the same configuration across all your environments.
5.
Security and Compliance: Security and compliance should always be a priority, and Kubernetes can help put the appropriate safety measures in place to keep your services and containers safe.
Make sure that all of your resources are up-to-date and secure.
6.
Use Helm: Helm is an important tool to use when it comes to managing releases of Kubernetes applications.
It will help you manage application lifecycles, upgrade configurations, scale components, and more.
7.
Use Taints and Tolerations: Taints and Tolerations on Kubernetes nodes are good ways to control resource allocations on nodes.
This will make nodes more efficient and help optimize performance.
8.
Utilize Resource Limits: Resource limits are important for Kubernetes.
Establish rules for CPU and memory usage, which will help prevent unintended system performance issues.
9.
Monitor with Stateful Sets: Stateful sets are helpful for monitoring applications or services that are running in Kubernetes.
This will allow you to see the state of each namespace and component of your application.
10.
Update Regularly: Regular updates and maintenance of Kubernetes components are a must.
Make sure that you are always on the latest version to take advantage of any bug fixes and performance enhancements.
