    At the completion of this setup expect to have a ROS2 Kubernetes cluster running MicroK8s on three different machines. Applying a single configuration file distributes the ROS 2 workload across the machines.

  • Finding the real source IP: using the PROXY protocol with syslog-ng - Blog - syslog-ng Community - syslog-ng Community

    Until now collecting logs behind proxies or load balancers needed some compromises. You either trusted the host information included in the log messages or you could only see the proxy as the sender host. Starting with syslog-ng 3.30 there is a third option available: using the PROXY protocol. While not an official Internet standard, it is supported by a number of popular software, like HAProxy. Other software can be extended to use it, like F5 load balancers using iRules. This way crucial information about the original network connection is not lost, but it is forwarded to the server by the proxy.

    From this blog you can learn about the PROXY protocol, how to enable it in the syslog-ng configuration, and how to send test messages using loggen directly and through HAProxy.

  • 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.
