  • How has nobody in this thread said check_mk yet?

    It’s free, you host it yourself. It’s built off of nagios, compatible with nagios plugins, supports snmp or agent based checks. It can email, SMS, slack or discord you when something breaks, you can write your own custom checks in any language that can output to a local console… I could never imagine even looking for something else.





  • I have condensed almost all of my workflows into pure bash scripts that will run on anything from bare metal to a vm to a docker container (to set up and/or run an environment). My dockerfiles mostly just run bash scripts to set up environments, and then run functions within the same bash scripts to do whatever things they need to do. That process is automated by the bash scripts that built my main host. For the very few workflows I have that aren’t quite as appropriate for straight docker (wireguard for example) I use libvirt to automate building and running virtual machines as if they were ephemeral containers. Once the abstraction between container and vm is standardized in bash, the automation doesn’t really need to care which is which, it just calls start/stop functions that change based on what the underlying tech is. Because of that, I can have the canary system build and run containers/vms in a sandbox, run unit tests, and return whether or not they passed. It does that via cron once a week and then supplants all the running containers with the canary versions once unit tests pass.

    Basically I got sick of reinventing the wheel every time a new technology came out and eventually boiled everything down into bash so that it’ll run on anything it needs to. Maybe podman in userland becomes the new hotness next year, or maybe I run a full fat k8s like I do at work. Pure bash lets me have control over everything, see how everything goes together, and make minor modifications to accommodate anything I need it to.

    It sounds more complicated than it really is, It took me like a week of evenings to write and it’s worked flawlessly for almost a year now. I also really really really hate clicking things by hand lol, so I automate anything I can. Since switching off proxmox, this is the first environment that I have entirely automated from bare-metal to fully running in a single command.

    I’m incredibly lazy; it’s one of my best qualities.


  • Virtual machines also exist. I once got bit by a proxmox upgrade, so I built a proxmox vm on that proxmox host, mirroring my physical setup, that ran a debian vm inside of the paravirtualized proxmox instance. They were set to canary upgrade a day before my bare-metal host. If the canary debian vm didn’t ping back to my update script, the script would exit and email me letting me know that something was about to break in the real upgrade process. Since then, even though I’m no longer using proxmox, basically all my infrastructure mirrors the same philosophy. All of my containers/pods/workflows canary build and test themselves before upgrading the real ones I use in my homelab “production”. You don’t always need a second physical copy of hardware to have an appropriate testing/canary system.


  • Generally end-user applications like Firefox would be the latest/same version, but system libraries might be a few versions different. Generally security patches are written for a few major versions of libraries/daemons at the same time. So features might be different but it’s all the same security for the most part.

    That’s the major draw between one distro to another, they will have different philosophies on what to include, and what major version to use. Debian for example is much more reluctant to upgrade something unless there’s a large demand for a new feature. The theory is it is more stable and consistent to use that way.

    Ubuntu on the other hand features much more modern versions of libraries because they want to be more hip and modern, expecting users to learn new things more often because they think the new features are worth it and they want to support all the things.


  • Yes but they use different repositories with different maintainers. Think of a package manager like steam, epic, etc, except instead of games it’s everything. Some package managers get different applications, some have different versions of the same applications. In the case of Debian/Ubuntu it’s more like steam in China vs steam in the rest of the world. Same steam, different games, different maintainers of who decides what games get to go in which steam.
