Docker daemon fails to start on voxl

As I'm working on this issue, I noticed the following.

It's not showing any IP address for docker0.
How to configure the IP address that will listen to docker daemon on voxl-core board?

Hey @Alex123 were you able to resolve this? I'm having the same issue.

Are you following the docs here?

The voxl-docker command is for developing in a Docker on a PC, it should not be run on VOXL.

The tutorial steps to run on target are:

yocto:/# voxl-configure-docker-support.sh
yocto:/# docker images
yocto:/# docker run hello-world

If you have run the PC scripts on VOXL, not really sure what would happen

@Chad-Sweet Thanks for the fast response!

Not really sure what state your system is in. This github issue shows it could be related to disk space or needs a reboot. Did you install other Dockers on the image? They are very large and maybe all of the space is consumed

Just looking at your script, I realized that modal has it's own docker services.. so perhaps this provides a little more info: I have created a few images from the kinetic image

I had a battery go pretty low and the system crashed while running mavros in docker last night, after reboot, docker deamon is not responding and I cannot see any images.

Eric Katzfey

@kiprock I would reflash the system, setup your IP connection, configure Docker and just verify that it works as expected.

kiprock

just looking at the logs, the docker deamon fails here:

level=fatal msg="Error starting daemon: Error initializing network controller: could not delete the default bridge network: network bridge has active endpoints"

Most forums suggest removing the docker network folder: rm -r /var/lib/docker/network

I did this but still having issues. Just curious if the modalAI setup stores docker files somewhere else?

Eric Katzfey

@kiprock Everything is stored on /data. But again, I would reflash and start over just to verify Docker operation.

kiprock

rm /data/network/files/local-kv.db

did the trick. Thanks for providing that missing piece of data!

@kiprock Hi I have a exactly same issue.

I flashed image and reset factory configuration on my VOXL, but, It has still issue.

Did you resolve this problem?

Thanks,

kiprock

@Eric-Katzfey if you cannot start docker images, you can try the command above to clear them. Good luck.

Eric Katzfey

Thanks, but I think you meant to ping @shlee853

shlee853

@kiprock thank you for your reply
I’ll try it

shlee853

@shlee853

Great!

I resolved this problem as you mentioned.

@kiprock Thank you for this, that also solved the issue in my case.

To be a little more cautious, I simply renamed the existing file, which forced the generation of a new one when running the configuration script voxl-configure-docker-support.sh:

voxl:/data/network/files$ mv local-kv.db local-kv_DISABLED.db

José Quintanilla

@modaltb I have a problem, after I write that line, the drone display a message that says: voxl:/$ voxl-configure-docker-suport.sh
bash: voxl-configure-docker-suport.sh: command not found
voxl:/$

@José-Quintanilla Looks like you spelled it wrong

@José-Quintanilla You can use [TAB] after you start writing a command to auto-fill
