Containerization of a Flask application
Flask can be seen as the equivalent of Express for Python. However, although an express application is basically production ready, a Flask app outputs the following when executed by itself:
Self-hosted GitLab instance for DevOps on Ubuntu 18.04
GitLab provides a great number of tools needed for the DevOps cycle of an application. In this guide, we'll install a GitLab instance on our own server and configure it to fit our DevOps needs. Here, we will use a fresh install of Ubuntu 18.04 as a base.
Getting Python's requests library to use a local DNS (Core-DNS, Docker-compose, etc.) while behind a proxy
When using Python's requests library, the requests are send through the proxy set as environment variables. Consequently, if the DNS to be used comes before said proxy, the host might not be resolved. This typically happens when resolving a host in Kubernetes using Core-DNS. If the request first leaves the Kubernetes cluster to reach the proxy, then the DNS server becomes unreachable, making the request fail.
Distributing a Helm chart on Artifact Hub
Building applications in a microservice architecture has become more and more popular recently. With this design pattern, an application is composed of multiple services that run independently and generally share data across network protocols.
TDD for an Express application
TDD has been proven to significantly reduce the amount of bugs in software releases. Moreover, with CI/CD systems, tests can be run automatically before the application deployment, preventing a faulty application to reach its end user. This guide goes through the steps required to set up a TDD workflow with an Express application.
Combining two independent git repositories
This article presents how to combine two independent and unrelated git repositories.
Node.js testing for multiple environment variables
Some applications might require the same codebase to be tested with different sets of environment variables. This article proposes a simple way to do so.
