Is there a qemu-like container running ubuntu?

I’m trying to set up one but running into issues running mender-connect which relies on dbus.
Is there - maybe - some kind of out-of-the-box solution running ubuntu (and not Yocto)?

Hi @uishon,

Did you try already these steps? QEMU, the FAST! processor emulator (Ubuntu)
Is there anything in particular that is not working after following the tutorial?

Regards,

Tried that and it is working for me on a clean ubuntu machine (except for one little issue which I’ve fixed - mender-inventory-geo script is missing an ipinfo.io token so it always fails). BUT, I’m trying to set up a container as a virtual device. When running inside a docker, mender-connect is failing with errors connecting to d-bus:

root@51bc6aa947bf:/# mender-connect daemon

WARN[2021-07-27T14:47:11Z] No server URL(s) specified in mender configuration.

ERRO[2021-07-27T14:47:11Z] Could not connect: No such file or directory

I assume it’s because dbus is not running inside the container which makes the setup more complex…

Here is my Dockerfile:

FROM ubuntu
COPY get-mender.sh supervisord.ini ./
RUN sh get-mender.sh

RUN apt-get update && apt-get install -y wget iproute2 supervisor

ARG DEVICE_TYPE="ubuntu"
ARG TENANT_TOKEN="XXXXXXX"
RUN mender --no-syslog setup \
            --device-type $DEVICE_TYPE \
            --hosted-mender \
            --tenant-token $TENANT_TOKEN \
            --retry-poll 30 \
            --update-poll 5 \
            --inventory-poll 5

RUN sed -i 's%https://ipinfo.io%https://ipinfo.io\\?token=XXXXXXX%'  /usr/share/mender/inventory/mender-inventory-geo

CMD supervisord -n -l - -c supervisord.ini
