NGINX 502 Bad Gateway: Gunicorn

Gunicorn is a popular application server for Python applications. It uses the Web Server Gateway Interface (WSGI), which defines how a web server communicates with and makes requests to a Python application. In production, Gunicorn is often deployed behind an NGINX web server. NGINX proxies web requests and passes them on to Gunicorn worker processes that execute the application.

Kubernetes Master Class: Deploy WordPress and MySQL without Data Loss

Applications such as WordPress or MySQL require the use of data persistence. It is common when deploying such applications to use a HostPath volume as it is agnostic from the platform. A HostPath volume shares the filesystem of the Host within the container making the data available between pod restarts. However, it ties the data to one node only, creating a single point of failure and restricting any kind of scalability. Kubernetes is not able to schedule the application in any other node even if it is unavailable. This leads to eventual data loss.

Why We Chose k3s to Power our Kubernetes Service

This blog post is an adaptation of a talk I gave at the Cloud Native meetup in Birmingham in the UK in February 2020. It details the advantages of k3s, a lightweight Kubernetes distribution we have deployed as part of a managed Kubernetes service. Developed by Rancher Labs, k3s allows for quick deployments for testing, CI/CD runs and getting to grips with Kubernetes without having to commit to large-scale infrastructure and the costs that would bring.

Episode 5: Let's Encrypt? Let's Not.

SSL support is table stakes for any modern website. Browsers and search engines penalize un-encrypted websites to such an extent that SSL is necessary just to participate in the modern web. In many cases it is a quick, easy option for configuring SSL. Let's Encrypt is held up as a one-size-fits-all solution to everything SSL, but there are downsides. Situations differ between applications and LE is not always the best fit. Let’s Encrypt isn't a fit for Request Metrics. For now, we’ll buy a certificate like grumpy old men.

What is Amazon ECS?

Many companies are moving their infrastructure and web applications to the cloud. Along with moving to the cloud, organizations are finding new ways to remain agile and nimble, especially when it comes to software. By utilizing Amazon AWS and Amazon ECS, companies are decoupling their monolithic applications and taking advantage of microservice architecture.
