Docker service error - l4t-32.5.0 with Mender

[tirankas]

Hello,
I have made a demo full image (docker, nvidia runtime, opencv etc) with Mender support enabled for Jetson NX Xavier.
The image seems to powerup fine but I have a problem with the docker support.

systemctl status docker

• docker.service - Docker Application Container Engine
  Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset>
  Active: inactive (dead)
  TriggeredBy: * docker.socket
  Docs: https://docs.docker.com

docker ps

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Anyone familiar with this error?

Can you include the output from journalctl -b -u docker.service? The log should tell you why it's failing to start.

If /var/lib and /home aren't getting mounted properly, you should be seeing more service failures than just docker. Did you make any changes to the distro setup? I just booted an image on my Xavier NX devkit built off dunfell-l4t-r32.5.0, and everything came up as expected.

The /data partition should be mounted, read-write, on /dev/mmcblk0p12. Overlay mounts should also be there for /etc/docker, /var/lib, and /home. If they aren't present, as @ichergui mentions, that should be investigated, since several services need to have writable storage, while with Mender we have a read-only rootfs.

Hi Matt,
Yes, this is my own distro (it's name is not tegrademo-mender) but forgot to rename places that depends on the tegrademo-mender distro.

Thanks

Issue solved, thanks for the help

Thanks @tirankas

but forgot to rename places that depends on the tegrademo-mender distro.

Is this some change we should make to documentation or https://github.com/OE4T/tegra-demo-distro/blob/master/scripts-setup/create-distro-layer ?

Hi Dan,
No, this is not really related.
It totally on my side.
I have renamed the distro name manually but didn't modify the append_distro macros.
Since I am now done with all my changes and everything work fine including capturing & analytics, I will get to the point of proposing changes to the manual, making sure everything is crystal clear...
