In this blog post however, we will present the good old way: we will use Laravel Envoy to deploy our code directly to our server(s). This method has the advantage of simplicity as it does not require to build containers, nor does it require a kubernetes cluster: Laravel Envoy uses a simple SSH connection to the target server(s) to perform the deployment.

Implement a Java detector for the Multi-Agent Ranking framework

MARk Java

In previous blog posts we showed how to inject a stream of data in the Multi-Agent Ranking framework, and how to use the built-in detectors to produce a ranking. This time we show how to implement your own detection algorithms.

Continuous Deployment with GitLab and Kubernetes

If you have a web application, with the appropriate Dockerfile, you can now go the next step and use GitLab to automatically deploy your application to a kubernetes cluster. Here is how...

MARk : Use built-in detectors


Now that you have a running MARk server, with data flowing in, you can use the provided algorithms to build your detection chain.

Getting started with MARk : create a PHP data injector


The Multi-Agent Ranking framework (MARk) aims to provide all the building blocks that are required to build large scale detection and ranking systems. For this blog post we will use docker and docker-compose to run a MARk server, then we will use PHP and composer to inject data in the framework.
