Kubernetes Direction

Challenges

In Kubernetes, the following aspects may be difficult to understand:

Conceptual understanding: Kubernetes has many concepts to understand, such as Pods, Deployments, Services, Ingress, etc. Beginners need to spend time understanding these concepts and their relationships.
Installation and configuration: Kubernetes installation and configuration are complex and require consideration of many factors, such as network configuration, node configuration, storage configuration, etc. Incorrect installation and configuration may result in a non-functional Kubernetes cluster.
Application deployment: Deploying applications in Kubernetes requires writing YAML files and understanding concepts such as container images, container ports, environment variables, etc. Beginners may find this challenging.
Scheduling management: Kubernetes has many scheduling management concepts, such as Node Selector, Affinity, Taints, etc. Beginners need to understand these concepts and their roles in order to better manage and schedule applications in the Kubernetes cluster.

The above are some of the aspects of Kubernetes that may be difficult to understand, and require more time and effort to learn and understand.

Network and storage are important directions in Kubernetes and require special attention. Here are some related concepts and considerations:

Network: In Kubernetes, Pods can communicate across nodes, but it is important to note that Pod IP addresses may change. In addition, there are other network-related concepts in Kubernetes such as Services, Ingress, etc.
Storage: There are two main types of storage in Kubernetes: persistent storage and temporary storage. Persistent storage is typically used to save application data, while temporary storage is used to save temporary data such as logs. When using these storage types, factors such as storage type, location, and size need to be considered.
