The world of Kubernetes can be both exciting and challenging, especially when it comes to day-to-day operation and maintenance. As a distributed systems engineer, you’re likely to be faced with many operational challenges as you grit your teeth towards mastering this complicated container orchestration system.
As someone who’s been working with Kubernetes for nearly two years, I’ve collaborated with developers and operations gurus to develop the following five tips for dealing with Kubernetes operational challenges.
1. Master the Kubernetes Command Line: One of the essential skills of the Kubernetes operations engineer is working on the command line. Kubernetes is a very large system and working with it on the command line is an invaluable way to become familiar with the system’s components. Before jumping into any new Kubernetes operations, be sure to master the basics, such as creating, editing, and deleting Kubernetes resources as well as running commands to monitor and troubleshoot the cluster.
2. Plan Ahead: Any Kubernetes operations engineer should be aware of the potential pitfalls of running short-sighted operational tasks. Kubernetes has a complex system architecture and component relationships, so making changes to one component could have unexpected effects. Ensure that all changes are well-thought-out and tested in a progressively manageable fashion.
3. Understand What Kubernetes is Doing Behind the Scenes: Many Kubernetes operations tasks involve managing Kubernetes resources, such as Services, Deployments, Pods, and Ingress. While it’s easy to get lost in all the technical jargon, it’s important to take some time to truly understand what each component does behind the scenes. This will help you better plan, troubleshoot, and diagnose operational issues.
4. Know Your Operational Alerts: Kubernetes can help you monitor and alert on a wide range of operational tasks, such as disk space warnings, container health, and resource scheduling. Be sure to subscribe to all the Kubernetes operational alerts and know what each alert means and how to respond to it.
5. Practice Regularly: Kubernetes is a large, complicated system and the best way to master it is to practice regularly. Take some time each day to practice Kubernetes operations tasks and get comfortable with the system. Make sure to log each task and the results of each task and review them regularly so you can keep improving.
By following the above tips, you’ll be better equipped to face many of the day-2 Kubernetes operational challenges. Mastering Kubernetes is a long process, so be sure to stay motivated and keep up the good work!
