docker
It’s almost outrageous to say that I don’t like distributed systems while working in a company that advertises as being cloud-native, headless and what not. And probably every SRE with some buzzword certifications may think I’m a complete idiot, but hear me out.
Roughly a year ago, I decided to switch to a Kubernetes based multi-node environment with one of my side projects. The promise of doing zero-downtime deployments and node maintenance, better scalability and “self healing” if a node goes down sounded too good to not jump on the ever-growing train of tech marketing.
I’m running a Docker host on a Hetzner Cloud server. Since my GitLab instance grew quite big, I bought some additional storage that’s mounted to the machine as a additional device. All my Docker stuff uses local volumes located in /var/lib/docker/volumes. The question now was: How to move those volumes to the new storage? Docker volumes are basically just subdirectories in a special folder. For some applications it’s important to copy over all the extended attributes and other metadata like permissions, ownership and change dates.
I’m working on an application where I use Docker and docker-compose to orchestrate a NodeJS container running my backend and a MongoDB container for my database. Using Docker for Mac, I’ve seen drastic slowdowns when initially establishing the database connection. When I used a Linux host, everything was extremely smooth. Since Docker for Mac creates a xhyve-based virtual machine running a Linux with the Docker daemon inside, I initially thought that this is just the usual slow in-VM performance compared to running Docker natively on the host system.
In this article I will show you how to set up a Firefox Sync Server as a Docker container. In my case this will replace iCloud Bookmark / Tab synchronization. This article is part of the byeCloud series in which I try to replace iCloud with self-hosted services.
I’ve evaluated different solutions to synchronize tabs and bookmarks, but none of them seemed to satisfy my needs. Firefox Sync almost does. Originally, I wanted to use Chromium with some plugin that would allow me to self-host a bookmark sync service.
For some months now I’m running a private GitLab server. I really enjoy using it, especially with all the great features like the Docker Container Registry and GitLab Pages to host static pages, even with own domains. Normally I would prefer a more lightweight solution, such as Gitea but GitLab has so many advantages that, at least for me, this is currently the only way to go. However, it felt tedious setting it up, even with Docker.
In this article I will show you how to set up your own RSS feed aggregator with sync support for many third-party clients through the Fever API as a replacement for Apple News/Google News/Feedly. This article is part of the byeCloud series in which I try to replace iCloud with self-hosted services.
Choosing the right software I fiddled around for a while with the News app for Nextcloud, ttr-rss and a few other alternatives, but ended up with Miniflux (now in version 2) because it is simple and lightweight and provides the most important thing for me, a Fever-compatible API without any plugins.
UPDATE Apr, 17 2018: Update imapsync to run as standalone docker container to make deployment easier.
In this article I will show you how to set up a fully-featured mail server including webmail as a Docker container. This article is part of the byeCloud series in which I try to replace iCloud with self-hosted services.
Let’s be honest: Setting up a mailserver really is a pain in the ass. Always. There are so many components involved, on a pretty standard setup starting from Dovecot and Postfix to Amavis, OpenDKIM, ClamAV, postgrey and much more.
In this article I will show you how I set up my photo synchronization using Nextcloud. This article is part of the byeCloud series in which I try to replace iCloud with self-hosted services.
One of the most important things in my setup is a solid and reliable way to synchronize Photos and videos I take. In one of the previous parts of this series I set up my Nextcloud instance.
In this article I will describe how I set up my Nextcloud instance aiming to replace iCloud Drive. This article is part of the byeCloud series in which I try to replace iCloud with self-hosted services.
The goals for a file syncing infrastructure are simple
I want a reliable solution that syncs files as-is, that does not corrupt them and does not cancel uploads all the time. Additionally, I want to be able to access my files on the go using a mobile app, as well as having files on my local hard disk to also be able to use it offline, just in case I have no network connection.
If you encounter any problems, please check the up-to-date documentation at https://github.com/dprandzioch/docker-ddns .
In some projects I need access to various hosts with a dynamic IP from time to time. Dyndns services offer a great solution by providing a DNS with records that are updated by the clients once their IP addresses change.
There are various existing services out there that are either free or paid, but if you want to self-host a dyndns service, you have to set up a DNS by your own as well as some endpoint that your clients can connect to in order to update their records.
