I have implemented this image one arm arch now a couple of times, (one is a PLC(armv8) the other is a PI-Zero(armv8)). In both cases the container works perfectly. In the container.conf file, there is a setting that won't allow you to run the container as root which is very smart. In my dockerfile, I have added a user with no password, and told docker to use that user but the container still won't run on my RB5009. Here is the syntax for the dockerfile:
FROM alpine
LABEL Name=rport Version=0.8.2
WORKDIR /app
COPY . /app
RUN adduser --disabled-password --gecos "" appuser && chown -R appuser /app
USER appuser
Is there something I need to do on the RouterOS side?
