How to install guacenc with docker? - docker

Question

I installed guacamole and guacadmin with docker, so I also wanted to install guacenc with docker, but I didn't find the information.
In fact, I have not found any other way to install guacenc.
If anyone knows, I hope I can get the answer.
Thank you very much

Answer 1

If guacamole and guacadmin can be installed on linux/windows/Mac OS then it can be run inside docker.
Here is the official docker image of guacamole on dockerhub, which you can try out.
Also check this out.
Update:
To install guacenc in centos docker image you need to install necessary packages as mentioned here.
Quoting the statement from this link.
The guacenc utility, provided by guacamole-server to translate screen
recordings into video, depends on FFmpeg, and will only be built if at
least the libavcodec, libavutil, and libswscale libraries provided by
FFmpeg are installed.
The libavcodec, libavutil, and libswscale libraries provided by FFmpeg
are used by guacenc to encode video streams when translating
recordings of Guacamole sessions. Without FFmpeg, the guacenc utility
will simply not be built.
You need to install these packages using yum install so that guacenc utility can be build and installed.
Hope this helps.

This dockerfile is only reference. thanks
# This is a Dockerfile to build the docker image including guacenc service and ffmpeg utility.
# To reduce docker image size, utilize multi-stage build method and copy shared library file required while executing guacenc.
# Copying shared library method is inspired by this thread "https://gist.github.com/bcardiff/85ae47e66ff0df35a78697508fcb49af"
