  • How to deal with OpenVPN Client Runtime Issues?

    In my practical human trials, I have encountered issues mostly with availability. The most common issue in my experience has been that the openvpn process dies due to an error condition it cannot handle, such as socket availability or an error condition with the client-server communication that it cannot deal with in a controlled manner.

    To this end, I first experimented with ifstated(8), but found out that it is not really the right tool for the task, since openvpn getting stuck is a rarer event than it exiting due to an error condition. Moreover, it remained unclear to me how to gracefully handle multiple independent processes and their state through the configuration. [...]

  • How to Register a Domain Name on AWS

    Amazon Route53 comes to the rescue when it comes to buying a domain name on AWS. One can also transfer a domain name from other registrars to AWS. When you want to build a website or web applications, the first step is to buy a domain name, as it is an easier way to remember than the IP of the server. A domain name is a unique name that identifies the website, hence no 2 websites can have the same name on the internet.

    Any domain consists of Top Level Domain (TLD) and Second Level Domain (SLD). If we take an example of the domain name as "my-example.com" .com is the Top Level Domain and my-example is the Second Level Domain. Additionally, you can create Sub-Domains under your Domain name for which you don't need to pay. In "my-subdomain.my-example.com" URL, "my-subdomain" is the Sub-Domain you can create it without paying any additional amount to your registrar.

  • 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.
