This article mainly explains "how to expand the Kubernetes plug-in", the content of the article is simple and clear, easy to learn and understand, the following please follow the editor's ideas slowly in depth, together to study and learn "how to expand the Kubernetes plug-in" bar!

1. Expansion of the security management and governance framework

For enterprises, the security management and governance framework is critical, but this is also the difficult part. Because different enterprises have different security requirements, security plug-ins also face challenges.

So, first, define the requirements and determine the correct extension; second, minimize the required framework while maximizing coverage. Some security frameworks will be integrated with overlay network extensions, or some Kubernetes security features can be utilized, including network policies, pod security policies, and so on.

2. Cloud native storage expansion

When you start using stateless applications for Kubernetes, you often come into contact with the area of stateful applications. At this point, you need a way to manage cloud native storage using specific extensions.

Kubernetes provides basic local storage capabilities. However, they may be inadequate in areas such as storage configuration, access management, or SLA for different storage types. In order to support scalable Kubernetes clusters through stateful applications, cloud native storage management, operations, and governance need to be performed automatically, such as Portworx,Storage OS and Robin. Open source projects can also choose Ceph and Rook.

3. Overlay network plug-in

Because containers must communicate in some way, overlay network (Overlay network) plug-ins are important. Although a cluster can run independently of the overlay network, using this extension of the overlay network can increase flexibility. There are many plug-ins that overlay the network, such as Calico,Weave,Flannel,Canal (Calico + Flannel) and Kube Router. Each cluster can be installed manually or separately for each cluster.

4. CI/CD pipeline plug-in

You can choose from various continuous integration and continuous delivery (CI/CD) extensions. Some are cloud-specific, while others are generic and can be used with Kubernetes or other deployment tools. Each of these tools is customizable to varying degrees. Some wrappers are packaged with preconfigured pipes, which limits customization, while others are less restrictive but require more setup work. When viewing options, consider the tools that the development team is using and their experience. CI/CD pipes can be integrated with Kubernetes and cloud native stacks through plug-ins. If not, consider using open source tools such as Jenkins,Spinnaker or a combination of both.

5. Portal management extension

The portal management extension can provide Kubernetes cluster services to external users. To do this, you can take advantage of the ingress controller in the cluster. However, more complex scenarios may require multiple entry controllers and integration with API management systems such as NGINX or Kong. Both tools are integrated with Kubernetes, cloud native tools, and different API management systems.

6. Runtime framework

There are many runtime extension frameworks, and when using these tools, it is important to note that they collect additional metrics dimensions from the application and should be integrated with Kubernetes log collection and monitoring. For example, a service grid can provide valuable tracking information for monitoring and solving various problems.

Thank you for your reading, the above is the content of "how to extend the Kubernetes plug-in", after the study of this article, I believe you have a deeper understanding of how to expand the Kubernetes plug-in, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
