jSpirit Unconference 2018
At January the 13th and 14th I've attended the jSpirit Unconference 2018.
hustior - new features
I've added two
new features to hustior: direct program execution and config
In my last posts I've written about the usage of Linux namespaces.
I've took the lessons learned there and went one step further to
create a sandbox called hustior.
Owncloud in a container: putting all together
In the previous posts I've explained how to run a container with my
Ownlcoud installation without docker but it still requires a lot of
commands to be executed manually and php-fpm didn't like to be run
as root. This post explains how to put all together to start it with
one command and also how to please php-fpm.
Owncloud in a container: device files
As I've mentioned in the previous post there was a problem in my
container that prevented it from starting the webserver. After some
debugging I've found that it was missing a random device and the
null device file in the /dev directory.
Owncloud in a container: getting the runtime files
In the last post I've explained the parts to isolate a container but
the runtime is still missing. With runtime I mean the program
files/executables to run my Owncloud installation. To make live easy
for me I've used a docker installation in a virtual machine.
Owncloud in a container: container and namespaces
As docker became more and more popular I've started to get my hands
on it. For that I've searched the web after documentation and
examples. While on that I've came across the following presentation:
of a Container: Namespaces, cgroups & Some Filesystem Magic -
LinuxCon. It introduced me to the concept of namesapces and
how they are used to separate conatainers from each other and the
Owncloud in a container
As I've mentioned in my last post I've
got a new computer. It required a newer version of Ubuntu which
broke my Owncloud
installation. To be fair I've used a "very stable" version of
Owncloud. I was already planing about updating to the latest edge
version as I've remembered a story about my scanner I've told to my
coworker a few days ago.
FreeBSDBackup Update 2017
In 2012 and 2014 I've blogged
about my FreeBSD based backup system. Lucky me didn't need it until
now. But this month I've got a new computer and took this as a
chance of testing the full restoring of all data. I've learned
two lessons I've want to share here.
All started when I've got a new toy: a GoPro Hero 5. So I went out
and took a 37 minute video. It turned out to be 13GB splitted in
multiple chunks of 4GB. That is a lot of memory especially when you
do make serious backups. As I knew that the were encoded in H.264
and that H.265 should reduce the file size about 50 percent I've
started to look for a way to reencode.
