Recently I have been testing one service and its clustering capabilities, in order to see if it fits in a project I'm working on.
I decided the easiest way to do this was by creating a couple docker containers and setting up a cluster between them. It should be an easy task in theory.
My first approach was using a docker-compose file and linking the containers between themselves:
version: '3' services: test_1: container_name: test_1 image: some:image links: - test_2 - test_3 test_2: container_name: test_2 image: some:image links: - test_1 - test_3 test_3: container_name: test_3 image: some:image links: - test_1 - test_2
The day Zend Expressive 2 was released I was super excited. I have been using it a lot for both professional and personal projects, so I'm quite used to it.
Since I've been using it in many projects, being able to update all of them to version 2 was a challenge, but I can say, I have succeed :-)
When I migrated my website to expressive, I had to create a custom router for backward compatibility reasons, because none of the provided implementations supports optional params at the beginning of the path, and I was using them.
It has been a long time since I first realized that handling file uploads in non-POST requests (like PUT) wasn't an easy task.
One could assume the
$_FILES array should be populated regardless the HTTP verb, but actually, PHP doesn't do it on its own.
After a long time wanting to find a solution to this problem, I've finally dedicated the time to get something functional, that allows file uploads to be transparently handled regardless the HTTP verb (it works the same way in POST, PUT and PATCH requests).
Since nowadays I try to work with psr-7/middleware based applications, I have created a Zend Expressive app that registers a middleware capable of parsing a
multipart/form-data request body, populating the request's uploaded files array and parsed body array.
Docker is, without any doubt, the trending tool these days. Everybody wants to use it, because it is very useful, allowing to easily generate development environments for any kind of application.
A couple months ago I started working with docker myself (it has taken me a while, I know), and now I can't imagine working without it.
I started using it at work, but now I'm migrating all of my OSS projects too.
Regardless docker is very cool, there is a problem when you start using it.
I had my development environment perfectly configured, and all my tools properly integrated. I was able, among other things, to run any project tests from within PhpStorm, just by right-clicking any test class, test method or phpunit.xml file, and selecting the "Run" option.
Let's Encrypt is the latest internet trending. Its a relatively young Certification Authority which intends to provide free and automated SSL certificates so that everybody can set encryption to their sites and applications.
It is a Linux Foundation project sponsored by most of the biggest Internet companies, such as Google, Facebook, Mozilla or Cisco.
They provide tools to automatically generate, setup and renew SSL certificates, but those tools are still in early stages, and not all the integrations are easy.
In this article I'm going to explain how to setup one of this certificates in an Amazon Web Services Elastic Load Balancer (ELB from now on).
