Hello Fedi friends,

Please stage an intervention. This is a special “my adventures in self-hosting - edition” toot.

So I need to learn #Docker in order to move my #Ghost blog there - possibly - as it’s the only way to let it federate (per the official Ghost.org documentation).

If you’ve followed me here for a while, you might have caught a running joke “please don’t tempt me to get a THIRD #VPS”.

This is my mayday, begging you: “please talk me out of getting a third VPS.”

I was happily doing online research wondering if I could install Docker on my #RaspberryPi5. Sure, it’s possible. Good to know.

Then things escalated when I started wondering: “hmmm how much would it cost to get a new VPS for Docker testing purposes?”

I checked out the website of my current VPS provider and noticed that you could get a basic VPS and pick an application that would come pre-installed. Docker is in the list of applications with a thumbs up next to it. Oh and I have a $20 credit after a commission. Awww the temptation!

I’m currently with my extended family in the middle of nowhere, with no WiFi in the house, one bar of 5G in most places (at best) and a laptop that refuses to connect to my phone’s hotspot. I’m typing this on my iPad (which is cooperating, vis-à-vis tethering). It’s my 12th day in this location, with 4 days to go before I return to civilization. I’m easily tempted because I’m going a little batty.

Please please please tell me that it’s better to learn Docker on my Pi 5. It’ll be waiting for me at home in a few days

Docker изнутри: исчерпывающее руководство. Механизмы контейнеризации + примеры, эксперименты и реализация / Хабр

> Практические примеры. Ссылки на репозитории с примерами: Containy –  реализация контейнерной утилиты на языке Golang Namespaces example – лёгкий пример работы пространств имён на C++.

...а если запустить процесс в отдельных пространствах имён и контрольных группах и с помощью `chroot` сделать его корнем директорию `merged`?

Верно! Получится контейнер!

В контейнерах за базовое дерево каталогов обычно берут не случайную папку, как наша `mycatalogs`, а стандартное дерево каталогов `ubuntu`, `debian` или `alpine` Linux. Такие деревья называются `minirootfs`.

Take back control: secure and private self-hosting on Debian with SSH keys, an ufw firewall and a robust fail2ban configuration. Use Docker and Caddy as a reverse proxy to securely provide your self-hosted services.

Step-by-step, minimal, and practical.

Does anyone know why JsonContent sometimes throws an IOException when it is used as HTTP request content, while creating a StringContent from JSON serialization does not?

I understand the difference, and that the second one creates the JSON content ahead, but I do not understand why JsonContent causes an IOException (connection reset by peer): https://github.com/testcontainers/Docker.DotNet/pull/33. #dotnet #docker #podman

Ich habe einen VPS und eine eigene Domain. Anschliessend habe ich eine #Subdomain erstellt und #Immich" als Docker installiert.
Aber wie verknuepfe ich das #Docker image mit der Subdomain?
Das sind meine ersten Gehversuche mit Docker, vielleicht kann mir jemand einen Tip geben?

How to connect a docker-image with a subdomain?
