I have correctly followed this guide but, when it comes to generating a Mender Artifact it seems the image must be available on https://hub.docker.io
What about if I create my own image with a Docker file i.e.:
# syntax=docker/dockerfile:1
FROM python:3.8-slim-buster
WORKDIR /app
COPY serial_write.py serial_write.py
RUN pip install pyserial
CMD [ "python3", "./serial_write.py" ]
Am I still able to use Mender? (I’m on a Raspberry Pi 4)
The Docker module supports normal Docker image syntax, which can include other servers. Check out this example from one of the Mender Enterprise images:
registry.mender.io/mendersoftware/workflows-enterprise-worker
However, it must be downloadable from a server. It does not package the Docker container inside the artifact. Someone asked about that functionality recently in the Update Module page.
Your link returns a 404 Not Found Page
So basically I first need to build the image, host it on a server, and run the Update Module to create an artifact that will download it from my server?
Yes, you need a login for that page. It was just meant as an example of the syntax, the actual link itself is unimportant.
Correct!
