If you don’t know yet, there were major changes by Google in protobuf and gRPC implementation for Go. New version should be better in all means so you should switch as soon as possible, if you are already using these technologies. In this article I am going to focus on Linux variant, but the upgrade procedure should be quite similar on OSX or Windows. In order to use protobuf compiler or generator, if you wish, you had to install protoc compiler....

In the Cloud era topics like backup became kind of less important. One of the reasons is probably possibility to take automated snapshots of your volumes, another maybe that you can use some kind of redundancy. However, there are still use cases where you need more traditional ways to backup your data. In this article we will discuss about syncing files from your Kubernetes volume to S3 compatible storage. If you know the concept of Persistent Volumes in Kubernetes, then you also know three of the supported access modes: ReadWriteOnce, ReadOnlyMany or ReadWriteMany....

Do you develop or plan to develop a Kubernetes native application in Golang, controller or operator? Such application strongly depends on being inside Kubernetes and development outside of Kubernetes may be a real hassle. Usually you have to build an image over and over again and restart the pod (with imagePullPolicy set to Always). This is very boring and time consuming procedure. Two years ago I developed an image to auto-recompile and auto-restart Go application, named go-reflex , but it was intented to be used by docker-compose....

Learn how to setup Traefik 2.2 on Kubernetes and how to automatically get TLS wildcard certificates. Traefik is a modern Web server made in the cloud era so it’s authors define it as a Cloud Native edge router. It is written in Go and it’s maybe not as fast as nginx or HAProxy, but it is fast enough and in the same time it has great features not present in traditional Web servers....

Since Traefik 2.0, this feature was possible just with custom IngressRoute resources, but it is now possible with normal Kubernetes Ingress as well. So, what is the Traefik middleware, anyways? It is a piece of code which is triggered just before the Ingress itself. Here you can find the full list of available directives that you can use to create your middleware. In this article we are going to define two middlewares, one to redirect www....
