  Kubernetes: Docker out

Recently，The hottest news in the Kubernetes circle that docker will be deprecated has been confirmed by the release of 1.20. Docker support in the Kubelet is now deprecated and will be removed in a future release. The Kubelet uses a module called “dockershim” which implements CRI support for Docker and it has seen maintenance issues in the Kubernetes community. We encourage you to evaluate moving to a container runtime that is a full-fledged implementation of CRI (v1alpha1 or v...

  Go Error Best Practice

Being indulged in Go for quite a while and having implemented web-related programs, grpc interfaces and Operators, I seem to be an advanced beginner now. However, I am still a raw hand in production-environmental debugging, which is cumbersome if done by querying logs or error messages. Imagine the scenario that a full-text search is called when the specific location of the error log is missing. Then what happens when those error logs are not only in one place? Yes, my error logs can no longer h...

  Breakdown Kubernetes Container Runtime

Keeping on learning Kubernetes piece by piece and having a deeper understanding of its advantages, I am no longer shocked at its rapid development and popularity. Though backed by big companies like Google is undoubtedly the push, its design, features, and convenience are the biggest attraction. Most of all, it disintegrates the monolithic Internet system governance and lifecycle and offers a new management method. Kubernetes is a set of concepts, including various resource types like Pod, Deplo...

You need it to query related Pod and Service information both in developing or performing some maintenance operations, such as events, scale, rolling update, etc. However, when using kubectl, there are many inconveniences. Though Kubernetes is officially maintaining kubectl¹, and you can submit the problems, improvement, and even PR in its Github Issues, you still have to wait long before its release. The m...

Authentication (from Greek: αὐθεντικÏŒς authentikos, “real, genuine”, from αὐθέντης authentes, “author”) is the act of proving an assertion, such as the identity of a computer s...

  When and How to Use the Go Channel

Go’s concise structure and powerful native library enable us to hit the ground running easily. It is more efficient than Java or Python when implementing the same functions, especially its concurrent programming, which is very handy and widely admired due to its goroutine and channel. goroutine and channel has much to dig into, and let’s start with channel, which I used to consider narrowly as a message queue to transfer data between gorouti...

  Secure Your Go Code With Vulnerability Check Tool

Security vulnerabilities exist in any language and any code, some are written by ourselves, but more are from the upstream dependencies, even the underlying Linux. We have discussed the security protection methods for Go and Kubernetes Image in Path to a Perfect Go Dockerfile and Image Vulnerability Scanning for Optimal Kubernetes Security, in which the security scanning was performed based on generic. As the Go community grows, more and more open-source packages have caused ...
