  • Getting Started With Swap Files on Linux

    A swap file in Linux is a file on your hard disk that the Linux kernel uses to store variable data of the applications running on your computer. A process known as swapping is responsible for transferring the data to a swap file when the Random Access Memory (RAM) doesn't suffice.

    Imagine you are running a memory-intensive application and the system starts using 100% of the RAM, the Linux operating system will use a swap file to avoid your RAM from filling up and rendering your system non-responsive or worse: crashing.

  • Analyzing cases for and against setting swap space on cloud instances | Enable Sysadmin

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
