  • How to Set Up NFS Server and Client on Ubuntu 20.04

    NFS (Network File System) is a distributed file system protocol that allows a user on a client computer to access files over a computer network much like local storage is accessed. It is a popular, cross-platform and distributed file system protocol used to export local file systems over the network so that clients can share directories and files with others over a network and interact with them as though they are mounted locally. This distributed file system protocol allows a user on a client computer to access files over a network in the same way they would access a local storage file. Because it is an open standard, anyone can implement the protocol.

    Ubuntu 20.04 supports NFS version 3(NFSv3) and 4(NFSv4). The default NFS version is 4.2 which features support for Access Control Lists (ACLs), server-side copy, sparse files, space reservation, labeled NFS, layout enhancements, and much more.

    In this guide, we will learn how to install and configure the NFS Server and NFS client on Ubuntu 20.04.

  • 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.
