What good is a status page, when its availability depends on the status of your own infrastructure? After all the status page (and your monitoring) should also be available when the rest of your infrastructure isn’t. Bonus points of the status page is even in a different region/with a different provider.
Fly.io is a hosting provider that generously provides a free tier (256MB Ram and 3GB of storage) which is large enough to run an instance of Uptime Kuma. ⌘ [Read more](https://blog.9wd.eu/posts/flyio/)

To automatically mirror a git repository from an internal system (like a private Gitea) to an external system (like Github) the following Script can be used as a so called “post receive hook”:

This blog is a recap instructions I originally documented in the Cloudron forum.
The strength of Cloudron is that its a simple single server installation that provides central user management for apps running on it. But sadly only for apps running on it. Sometimes you want to use the same users for file shares, windows logins or external applications that support LDAP like media servers and NAS devices.
For this a server that can act as a windows domain control can c ... ⌘ [Read more](https://blog.9wd.eu/posts/cloudron-ucs/)

Since my current Cloudron installation was both running out of disk space and running a soon unsupported version of Ubuntu, it was time to move it to a new and bigger server. Luckily the way Cloudron is setup makes this already very easy, but since I am using some of its apps in a production manner (like for example its mail server) I cannot just tell everybody, that would connect to the server to please not do it for a given timeframe. ⌘ [Read more](https://blog.9wd.eu/posts/cloudron-migration/)

While I value self hosting for the learning value, I also see a benefit of looking across the table to solutions that may be externally hosted, but are good to know and use not only because of their use in the business world, but also because having a reliably third party service e.g. for (backup-)access, messaging and monitoring can greatly simplify ones infrastructure. And since these services know their value to large scale businesses, they often provid ... ⌘ [Read more](https://blog.9wd.eu/posts/9wd-tech-external-services/)

The time has come to perform some much needed changes in my private IT landscape. Over the years a collection of single board computers, physical and virtual machines has formed the base for my own IT “zoo”, and as time has progressed some parts of it are in need of an overhaul, since they have been built on changing needs and past assumption, that may have not turned out as wise as once thought. ⌘ [Read more](https://blog.9wd.eu/posts/9wd-tech-intro/)

In my endavour to rebuild my IT infrastructure (with a Gitops-ish approach in mind) I needed to take a short break to figure out how to securely store secrets inside of my git repository. There are multiple approaches to this and then there is of course also the possibility to not store any secrect at all in git, but rather retrieve them at runtime from e.g. Vault. One popular solution when looking for “encrypt git repository” is git-crypt and while I have used it in the past  ... ⌘ [Read more](https://blog.9wd.eu/posts/git-encryption-age/)

Preamble: I like running containers in my own infrastructure via docker-compose. Through it you can easily define the properties of your containers and their relations to each other. Which makes maintenance and even migration much easier. Sure in a business environment (and if the application is suitable for it) you may be using a proper container orchestrator like Kubernetes, but Kubernetes comes with its own added complexity and even in a business environment you may not want ... ⌘ [Read more](https://blog.9wd.eu/posts/9wd-tech-authentik/)

Cloudron is a platform to easily install, run and maintain apps on a publicly hosted server. Apps are installed from an app store and the server as well as installed apps can automatically update once a newer version is available. Cloudron also takes care of backups (for example nightly and before performing an update) which makes it easy to either roll back to an older version or in case of hardware failure restore a system (incl. ⌘ [Read more](https://blog.9wd.eu/posts/cloudron-cheats/)

Runme is both a cli tool and an extension for Visual Studio Code and it makes your markdown server documentation executable.
When setting up a system or playing with a new piece of software I often like to write myself a small README.md files. These then provide little copy & paste instructions for various tasks, but there is one main problem with this. It is still a constant case of switching between windows and terminals. ⌘ [Read more](https://blog.9wd.eu/posts/runme-readme/)

One application I use quite often on my own Cloudron is Gitea.

The Steam Deck also has a desktop mode, but as SteamOS is immutable by default, additional applications need to be installed via flatpak, which does not offer the same variety of applications as other distributions such as Ubuntu. ⌘ [Read more](https://blog.9wd.eu/posts/distrobox-assemble/)

Once added to the app, the tag behaves just like a regular AirTag and even allows you to share it with other Apple users. Only the hardware looks a little different. Compared to the original, the Kruidvat tag seems a bit power hungry. ⌘ [Read more](https://blog.9wd.eu/posts/kruidvat/)
