Hello,
I’m attempting to dockerize HomeSeer 4 for the Raspberry Pi. Partly for security but mostly because I want to learn more about Docker. I’m having 2 issues that I can’t seem to get past and was hoping you could help. Please keep in mind that I’m both a Docker & Linux newb.
Here is what I have so far, and why.
OS / Rasbian - Buster
I downloaded the compressed HS4 install file and extracted it to /dockerbuild/homeseer
I created a Dockerfile with the following contents:
FROM arm32v7/python:3
RUN apt-get update &&
apt-get install -y --no-install-recommends
mono-complete
mono-vbnc
mono-xsp4
COPY HomeSeer /homeseer
cmd [“mono /homeseer/HSConsole.exe”]
I ran docker build -t “homeseer_rpi4:v1” . it provides the following error message "
E: Unable to locate package mono-vbnc
The command ‘/bin/sh -c apt-get update && apt-get install -y --no-install-recommends mono-complete mono-vbnc mono-xsp4’ returned a non-zero code: 100
I’m able to install mono-vbnc just fine by running apt install mono-vbnc while not building the image so I have no idea how to troubleshoot this. I decided to remove the line for now to see what happens.
The image is created successfully!

Successfully tagged homeseer_rpi4:v1
I know it won’t work without mono-vbnc but I try to run it anyway. I get the following error message:
docker: Error response from daemon: OCI runtime create failed: container_linux.go:367: starting container process caused: exec: “mono /homeseer/HSConsole.exe”: stat mono /homeseer/HSConsole.exe: no such file or directory: unknown.
ERRO[0001] error waiting for container: context canceled
I tried a bunch of combinations in the CMD field to no avail. So I checked out the file system of the image by using docker run -it --entrypoint sh homeseer_rpi4:v1 and I’m able to see /homeseer/HSConsole.exe just fine.
I guess it’s possible the error is caused by not having the VBNC dependency but when I run mono /homeseer/HSConsole.exe inside the image it gives me a very different, but predictable error.
Unhandled Exception:
System.TypeLoadException: Could not load type of field ‘HSConsole.My.MyProject:m_ComputerObjectProvider’ (0) due to: Could not load file or assembly ‘Microsoft.VisualBasic, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’ or one of its dependencies.
[ERROR] FATAL UNHANDLED EXCEPTION: System.TypeLoadException: Could not load type of field ‘HSConsole.My.MyProject:m_ComputerObjectProvider’ (0) due to: Could not load file or assembly ‘Microsoft.VisualBasic, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’ or one of its dependencies.
So I don’t know what to do next. I need to fix both problems before I even try to build a container. Can anyone help?
On a side note - I read that I need a base to build my image, so I picked arm32v7/python:3. My image seems quite large (1.1gb) considering HS4 is under 50mb. Is there something else I can use that would get the job done and keep my image small?
