Mythtv in Docker. Missing files?

jmgibson1981 · 11-12-2020, 01:05 PM

My problem is moving my mythtv-backend into Docker. The location of the maintenance scripts is empty, namely

Code:

/usr/share/doc/mythtv-backend/contrib/maintenance/optimize_mythdb.pl

does not exist. When installed bare metal it shows up just fine?

Code:

# no frills repository mythtv backend #
FROM ubuntu:focal


# needed for tzdata
# https://stackoverflow.com/questions/44331836/apt-get-install-tzdata-noninteractive

ENV DEBIAN_FRONTEND=noninteractive
RUN apt update && \
	apt full-upgrade -y && \
	apt install -y curl && \
	ln -s /usr/share/zoneinfo/$(curl https://ipapi.co/timezone) /etc/localtime

RUN apt install -y --no-install-recommends \
	ssh \
	man \
	x11-apps \
	sudo \
	xauth \
	xvfb \
	xmltv-util \
	mythtv-backend && \
	apt clean && \
	rm -r /var/lib/apt/lists/* && \
	echo "mythtv ALL=(ALL) NOPASSWD:ALL" > /etc/sudoers.d/mythtv

COPY config.xml /etc/mythtv/config.xml
COPY sshd_config /etc/ssh/sshd_config
RUN chown mythtv:mythtv /etc/mythtv/config.xml && \
	echo "mythtv:mythtv" | chpasswd

Not sure how important it is. I typically had this script run once a week. More interested in why it's missing really.

It appears that the script may be tied to the explicit Ubuntu operating system as opposed to being for a container. Have you asked on the MythTV forums for a similar maintenance script that would be useful in a container?

jmgibson1981 · 11-13-2020, 07:16 PM

Never considered that. I assumed it knew it was an Ubuntu container and that was that. I just did a post on Mythtv forums. Will report back.

I would check the /etc/os-release file on both systems (full install and container) and compare. Also, compare the output of "uname -a" on both. You will likely see differences that may be behind why the script gets installed on the full install but not the container.

The only thing that made me think along these lines is because it appears that the script is doing myth updates as well as possibly OS updates, and knowing the distro is key to ensuring that the updates are scripted correctly.

Both os-release & uname -a are the same output. I checked lsb-release (installed in container after your initial response) and it is identical to the host. Even rebuilt the container intalling it first, then the second install command did the mythtv-backend.

The script I'm mainly looking for is supposedly just for cleaning up the database. It's a perl script.

Suppose I could manually track it's paths and manually stick it in there. Didn't think of that.

Marking solved. Why the libdbi-perl and libmythtv-perl packages weren't pulled automatically I cannot say. I had to manually get the script from their git. I hope it's not against any rules to say I won't bother going there again. I can't even post their own file names to my thread. As such I couldn't show them my dockerfile or anything. Waste of time

This is a working Dockerfile for a basic mythtv-backend. Including link to my git for the other files as needed.
