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.
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.
For a project I was working on, I had a folder structure full of images and wanted to compress them to a specific maximum resolution in-place while retaining the aspect ratio using ImageMagick. The crucial point, as so often, were spaces and special characters in the folder names, making it really hard to use bash loops etc. to make this work. With the NULL character trick, luckily this works pretty well.
I maintain an archive of videos, especially documentaries from public media libraries from tv channels etc. on my NAS. Whilst I can use youtube-dl for the most part, it’s rather difficult for sites that use HTTP live streaming (HLS) to stream their content. In the most cases this is even AES-128 encrypted, which makes it difficult to download it. But since there’s players that support playback, it’s obviously possible to decode the stream on the client side.
During a setup change I had to temporarily move my incoming mailserver to Gmail and while I am now back in my own mail server, I again had this major headache of configuring the my DNS (using BIND) because I always forget the dots in the end of CNAME and MX records because usually I dont create nameserver records for external domains… So anyway here is the final configuration I used in Hetzners Domain Robot:
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.
As it turns out, the Apple Time Capsule only uses SMB protocol version 1 and NTLM for authentication. While this works with macOS without any changes, it often creates problem when trying to mount the the Time Capsule’s SMB share on a Linux system. With this parameters, mounting should work out of the box, given you have the cifs-utils (Debian/Ubuntu) installed:
sudo mount.cifs //10.0.0.1/Data /mnt/timecapsule/ -o password='yourpw',sec=ntlm,uid=<local user>,vers=1.0 If you have any problems or further insights, feel free to leave a comment.
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.
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.
It’s more than likely that your email provider of choice, especially the ones
that offer mail services free of charge, will not support receiving email to
custom domain names like, in my case, davd.net. Running your own mail server would
solve this problem but running a fully featured mail stack including POP, IMAP,
Sieve filters et cetera requires a fairly powerful machine.
Additionally, if not configured properly, there’s big potential for abuse,
As an alternative, it’s possible to just run a MTA which redirects all incoming email
to an external mail server.
This can be ran on almost any machine, even on a low-budget computer like the
Raspberry Pi or a cheap virtual server.
During the last few months I managed to automate many recurring tasks on my NAS.
One good example for those task is updating my podcast archive. I tried to accomplish
this using a lightweight shell script which, running as a cronjob, would hold my
podcast archive up to date and notify me about new episodes via push notifications.
So it’s already been a month ago when I got my new 13-inch MacBook Pro w/ Retina
Display. So everyone who knows me could already promise what would happen next:
I’d install Linux on it. For this one I once again chose to use my favorite Linux
distribution Fedora, which is currently available in version 20. Meanwhile I tried
to install Ubuntu but this lead to problems with ACPI, the disk controller and
last but not least the hi-res display featuring a pixel density from 227 ppi.
There are some things to have an eye on during the installation process but
generally most things are working now so that the system is more or less ready
for production usage.
