Shared networking for Virtual Machines and Containers

This entry explains how I have configured a linux bridge, dnsmasq and iptables to be able to run and communicate different virtualization systems and containers on laptops running Debian GNU/Linux. I’ve used different variations of this setup for a long time with VirtualBox and KVM for the Virtual Machines and Linux-VServer, OpenVZ, LXC and lately Docker or Podman for the Containers. Required packagesI’m running Debian Sid with systemd and network-manager to configure the WiFi and Ethernet interfaces, but for the bridge I use bridge-utils with ifupdown (as I said this setup is old, I guess ifupdow2 and ifupdown-ng will work too)....

Kubernetes Static Content Server

This post describes how I’ve put together a simple static content server for kubernetes clusters using a Pod with a persistent volume and multiple containers: an sftp server to manage contents, a web server to publish them with optional access control and another one to run scripts which need access to the volume filesystem. The sftp server runs using MySecureShell, the web server is nginx and the script runner uses the webhook tool to publish endpoints to call them (the calls will come from other Pods that run backend servers or are executed from Jobs or CronJobs)....

Using Git Server Hooks on GitLab CE to Validate Tags

Since a long time ago I’ve been a gitlab-ce user, in fact I’ve set it up on three of the last four companies I’ve worked for (initially I installed it using the omnibus packages on a debian server but on the last two places I moved to the docker based installation, as it is easy to maintain and we don’t need a big installation as the teams using it are small)....

New Blog Config

As promised, on this post I’m going to explain how I’ve configured this blog using hugo, asciidoctor and the papermod theme, how I publish it using nginx, how I’ve integrated the remark42 comment system and how I’ve automated its publication using gitea and json2file-go. It is a long post, but I hope that at least parts of it can be interesting for some, feel free to ignore it if that is not your case …​ 😉...

New Blog

Welcome to my new Blog for Technical Stuff. For a long time I was planning to start publishing technical articles again but to do it I wanted to replace my old blog based on ikiwiki by something more modern. I’ve used Jekyll with GitLab Pages to build the Intranet of the ITI and to generate internal documentation sites on Agile Content, but, as happened with ikiwiki, I felt that things were kind of slow and not as easy to maintain as I would like....
