Robusta is based on Prometheus and uses webhooks to add context to each alert. IP routing and network address translation (NAT).Īnd for better or worse, no code is required to make the networking magic happen.As a result, it'll become apparent that the single-host container networking is nothing more than a simple combination of the well-known Linux facilities: While answering these questions, we'll setup a container networking from scratch using standard Linux tools. How to reach containers running on a machine from the outside world ( aka port publishing)?.How to turn containers into friendly neighbors, prevent them from interfering, and teach to communicate well?.How to virtualize network resources to make containers think each of them has a dedicated network stack?.In this article, we are going to answer the following questions: Or, more precisely, a single-host container networking problem. Now comes a time to tackle the container networking problem.

Luckily, we've been looking under the hood of the containerization technology for quite some time already and even managed to uncover that containers are just isolated and restricted Linux processes, that images aren't really needed to run containers, and on the contrary - to build an image we need to run some containers. In a good way for those who understand the internals and in a terrifying - for those who don't. Working with containers always feels like magic.
