Dev With Imagination

The Eclipse MicroProfile project has been evolving over the last few years, but only in the last month or so have I started taking a proper look into it.

The mission of the project is described to provide:

An open forum to optimize Enterprise Java for a microservices architecture by innovating across multiple implementations and collaborating on common areas of interest with a goal of standardization.

–microprofile.io

The collection of framework specifications which are included in this standard, when used along with JAX-RS, provides the pieces required to build applications in a modern “microservices” architecture, while leaving behind more legacy aspects (and bloat) of the Java EE specification.

In my start of the year post, I had given up with attempting to get Pi-hole to work as a DHCP server while in a docker container and had started using “isc-dhcp-server”. The main driver to having Pi-hole performing DHCP was so that in the dashboard I could see actual hostnames as opposed to the IP addresses of the clients. Instead of persevering with trying to get DHCP working in the Pi-hole container, I took advantage of changes I was making in my home network setup.

Since I rebuilt my server I have been seeing issues where my use of the transcode-video docker image would consistently fail to complete the encoding process with this error.

transcode-video: invalid byte sequence in US-ASCII

The linked post led me to the solution - I needed to update the Dockerfile for my version of the image to include additional commands to configure the locale. This was a pretty easy addition as I already was using my own to customise a couple of things. I do not know why the appeared, but all I really care about is that it is working again now.

FROM ntodd/video-transcoding
  
# Configure locale
RUN locale-gen en_GB.UTF-8
ENV LANG en_GB.UTF-8
ENV LANGUAGE en_GB:en
ENV LC_ALL en_GB.UTF-8

Ah, the Christmas holidays - a few weeks of rest & relaxation, not having to think about work at all.

So of course it was time to get some little ongoing projects moving!

(Warning - this feels like a long one!)

In the last part of this series we got the Official Xbox One TV Tuner working successfully with Plex on a beta version of Fedora 28.

Last weekend one part of the RAID-1 boot drive array I used for my media server failed, so I took the opportunity to give Fedora 28 a shot as my boot OS with the replacement drive as opposed to imediately repairing the RAID. If this didn’t work out I can still swap some drives around and let the RAID resync. This may still happen, as Fedora is not offically supported on the HP Microserver I run, so I miss out on some of the agents used by the Integrated Lights-Out (iLO) server management interface to report back machine metrics.

As part of this switch I am re-evaluating what I can use Docker for, and so have OS distribution agnostic, scripted, services. Even if I do choose to switch back to CentOS this will not be a waste as there were some software packages which I was already compiling from source due to a lack of availability in CentOS repositories. When Ubuntu move to the 4.16 kernel I will likely switch again, but should have an easier time as I can re-use the configured Docker containers I have already scripted.

So it is now time to get Plex working on Docker with this tuner.
