Common Kubernetes Errors Made by Beginners [2024]
Most problems with Kubernetes adoption ultimately stem from the complexity of the technology itself. There are unobvious difficulties and nuances of implementation and operation, and there are underutilized advantages. Additionally, as you use Kubernetes more frequently, you can become a victim to alert fatigue. As a result, you lose money.
After a few years of experience with Kubernetes and several consultations for various clients, I have noticed some common Kubernetes errors. So, I thought of selecting and discussing the 6 frequent ones.
- The selector of the labels on the service does not have a match with the pods
To function correctly as a network balancer, a service generally specifies selectors that allow you to find the pods that are part of the balancing pool. If there is no match, the service has no endpoints to forward traffic to, and an error occurs. Bear in mind that the load balancing towards the pods is of a random type.
2. Wrong container port mapped to the service
