Incude script in initial image

mexekanez · September 30, 2019, 10:27am

We need to be able to build an image which could be flashed on the USB. This image would contain a file called " auto_run.py " or " auto_run.sh ".

The idea is: as soon as the USB is connected to the machine (Edge device), the script should run automatically. This script would perform an operation like making an API call, storing some logs, repairing an API and etc

dansku · September 30, 2019, 11:32am

Hey @mexekanez,
you must first provision your device with balenaOS, then the auto_run script should run inside a container.

You can also check the SDK, which you can use to control the API from the device. https://github.com/balena-io/balena-sdk

Let me know if you have ay questions.

Cheers

mexekanez · September 30, 2019, 1:05pm

@dansku Hi!
No I don’t want to wait while device will pull updates. I want that script is in image before sd burn. and will run after usb connected

dansku · September 30, 2019, 2:01pm

Hey @mexekanez, one thing that you can test is the balena-preload project => https://github.com/balena-io/balena-preload

Take a look at the repository and see if that would help with your requirements.

Cheers

mexekanez · September 30, 2019, 2:11pm

yes I understood that I can use only preload OR build yocto image.

with preload I have an issue (using openBalena):

 balena preload balena.img --app 12 --commit 9bde88b0e12e4b34228ace17a71d45ab

Hey there! Is the error message actually printing “https://registry.DOMAIN.xyz/v2/”? If not, what is the actual domain?

mexekanez · September 30, 2019, 2:28pm

hi!
actual domain:
https://registry.visoagent.xyz/v2/
as I said I using openBalena

richbayliss · September 30, 2019, 3:10pm

@mexekanez I tried to look at the domain you listed, and I only so the registry exposed on HTTP and not HTTPS. This would explain the issue, since the preload script it trying to use HTTPS and it reporting a timeout before receiving headers; which would happen if the TLS layer couldn’t be established correctly.

For openBalena I think you should have HTTPS going to your registry container, so I am not sure what setup you have but it looks like something isn’t configured correctly. By default openBalena will expose port 443 to the haproxy container, which reverse proxies the request to the registry container. I would start by looking there to see if you have something misconfigured

mexekanez · October 1, 2019, 8:10am

hi @richbayliss
not sure what you mean
bot domain working well http and https
http://registry.visoagent.xyz/v2/
https://registry.visoagent.xyz/v2/

where is an issue?

I have all ports opened on openBalenaOS

mexekanez · October 1, 2019, 11:51am

@here any thoughts?

afitzek · October 1, 2019, 12:16pm

Hi,
Could you try to run balena-preload from your laptop with NODE_EXTRA_CA_CERTS=~/open-balena/config/certs/root/ca.crt. Maybe the problem is that balena-preload cannot verify the self signed CA certificate.

mexekanez · October 1, 2019, 4:47pm

nope, doesn’t works @afitzek

mexekanez · October 1, 2019, 5:09pm

where I can check logs in OpenBalena?

robertgzr · October 1, 2019, 5:19pm

How are you running it? Did you follow the instructions here: https://www.balena.io/open/docs/getting-started/?

mexekanez · October 1, 2019, 5:21pm

yes.

also I have the same issue with balena cloud:

really confused…

mexekanez@mexekanezlaptop:~$ balena -v

what else I can check to get point where it doesn’t works?

chrisys · October 1, 2019, 11:02pm

@mexekanez it’s strange that you would have the same/similar error for both different methods.

Looking at the first log you posted I note the section dial tcp: lookup registry.visoagent.xyz on 192.168.0.1:53: read udp 192.168.0.103:35298->192.168.0.1:53: i/o timeout. This looks like it’s trying to contact a DNS server on your local network, and failing. It would make sense that both methods fail in the same fashion if the container is unable to resolve DNS for either of them. It’s hard to speculate any further without knowing your network setup but perhaps this is something to look into?

mexekanez · October 2, 2019, 7:38am

I checked /etc/resolv.conf
and put

nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 127.0.0.53

roman-mazur · October 2, 2019, 9:16am

@mexekanez So did the change help with the issue?
