[RESOLVED] Resin-cli preload stuck at "reading image information"

Product support
1

I am trying out resin-cli tool to preload my image. But after a few tryings, it always stuck at the same step.

$ resin preload kiosk.img --app Kiosk
Building Docker preloader image. [========================] 100%
/ Creating preloader container
- Starting preloader container
\ Fetching application Kiosk
| Fetching application Kiosk
\ Reading image information

And in docker, I see an image as

resin/resin-preload   latest              6c03d0547073        6 hours ago         278MB

But no running/stopped container.

What should I do?

Hi, can you run it with DEBUG=1 added in front of the command? That is:

DEBUG=1 resin preload kiosk.img --app Kiosk

and paste if there’s any more info here?

What device type is the Kiosk application? What OS are you running this on?

7

That is quite helpful. I got some error message. Interestingly, that did not stop the whole process. I will dig from here.

The device type is ARMv7hf, the command was run on Ubuntu x64.

Hi,

Thanks for the response, could you please give us the version numbers for:

  • resin-cli (resin --version)

  • resin-preload (npm ls | grep resin-preload)

  • Ubuntu

that you’re using, and the actual device type (the architecture is armv7hf, so is this, for example, a Raspberry Pi3?).

Many thanks, Heds

  • resin version: 7.9.3
  • resin-preload: I do not have such node module since my resin is prebuilt binary (downloaded as resin-cli-v7.9.3-linux-x64.zip)
  • Ubuntu: 18.04.1
  • Actual Device is RaspBerryPi 3.

Hi,

Apologies for the multiple questions. Could you also let us know the current version of Docker that you’re using? We’re trying to ascertain what might be causing these problems so need to keep looking at different components.

Best regards, Heds

No worries. Glad to help.

Package: docker-ce
Version: 18.06.1~ce~3-0~ubuntu

Hi, can you please run the following command:

docker run --rm -v PATH_TO_YOUR_IMAGE:/resin.img resin/resin-preload sfdisk --dump --json /resin.img

?

62

Not quite sure about the first resin.img part. PATH_TO_YOUR_IMAGE:/resin.img, what does it mean? I replaced it with my output name (./kiosk.img), and got:

sfdisk: cannot open /resin.img: Is a directory
63

You should use the absolute path to the image, like docker run --rm -v /absolute/path/to/kiosk.img:/resin.img resin/resin-preload sfdisk --dump --json /resin.img

64

Thanks. So got same error:

sfdisk: cannot open /resin.img: Not a tty
65

This is very strange

67

Can you try deleting the resin/resin-preload docker image and the containers using it and retry the same command as above ?

69

or running docker run --rm resin/resin-preload sfdisk --version, you should get sfdisk from util-linux 2.28.2

70

So I removed the image and reran the command.

Seems to be the same issue as on https://github.com/resin-io/resin-cli/issues/878

I am struggling with the same issue on Windows 10. I have sfdisk from util-linux 2.28.2. DEBUG=1 doesn’t show errors.

I think I get it. My output image (kiosk.img) was zero sized. If I filled it with some random data, the “not a tty” error was gone. I got “sfdisk: failed to dump partition table: No error information” instead, which apparently related to the image file.

I think preload command requires a working image as input, not as I thought, an image creating tool.

73

@magicloud, yes you are correct the preloader is not an image creating tool, but rather a tool for injecting docker images into a resinOS images so that they boot on initial provisioning.

74

Thanks. So I marked this thread resolved.
