Part of my daily routine is to consume, design and deliver services built for HTTP clients. This might manifest in something special like WebSocket, Protobuf but most often a plain JSON REST API. In any case, the performance is key, and an Undertow REST API with JAX-RS can deliver a stable performance under consistent load. In this article, I will cover some basics for setting up and deploying a REST API with Undertow, in Docker.

This post is a walkthrough on my approach to develop and deploy Golang web service in Docker container. There are many reasons for integrating Docker into the daily routine as a developer, one being the simplification of setting up a separated runtime environment. Using containers in production has, even more, advantages from simplified release to better performance. Kubernetes and Docker Swarm is gaining more and more space, which I think is partly because of the simplified management on IBM Cloud and Google Cloud Platform.

Cap crawler is a simple python crawler with multi threaded execution and shared execution queue, with cli execution options. This project is a wrapper(API) around cap crawler implemented in Php Zend Framework 2 and Cassanadra. The project is available on Github, clone it 🙂 Features Private/public key or password based authentication Hmac(sha256) based request authentication (similar to AWS authentication) Chained validation(Auth<>identity<>endpoint<>request etc.) Json/Csv/zip response options Stateless & scalable Custom error handling Dependencies
