Docker hello_world not running

Hi,

I am working on a custom carrier board using following setup:

  • Colibri iMX7D 1 GB V1.1A
  • Kernel 5.4.193-5.7.3-devel+git.f5d73fd6e9f8
  • Based on Toradex BSP Layers and Reference Images for Yocto Project 5.7.3

I would like to use docker within this image, so I included docker-ce in the image recipe, added the meta-virtualization layer and bitbaked it. After installing it onto the target, I get following output regarding docker version:

root@colibri:~$ docker version

 docker-init:

  GitCommit:        fec3683-dirty

Now when I run the docker ‘hello-world’ example I get following output:

root@colibri:~$ docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
c4018b8bf438: Pull complete

Status: Downloaded newer image for hello-world:latest
http: invalid Host header

What am I doing wrong or what can I do to make the example work?

Here is the output of the images:

root@colibri:~$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

Thank you for your support on this.

Cheers,
Rob

Hi Robbie,

It seems like this is a known issue from the upstream Golang client fails to attach to streams with "http: invalid Host header" with go1.20.6, go1.19.11 · Issue #45935 · moby/moby · GitHub.

What is the hash of meta-virtualization you used? Because it may be something that needs to be fixed on their side.

Hi @leon.tx,

Thanks for the quick response. The hash is 35c723774ee06b3c1831f00a2cbf25cbeae132e1 (this is on dunfell branch).

What could I do to resolve this issue?

Thanks.

Rob

Hi @Robbie !

Quickly reading the link shared by @leon.tx, seems like updating it could help.

Have you tried it?

Btw, Toradex has the TorizonCore, which is a ready to use distro with Docker, OTA client update (to be used with Torizon Platform) and a very nice developer experience with several tools to make your development easier.

Since you would like to have containers on your embedded OS, maybe you would like to test TorizonCore :slight_smile:

Best regards,

Hi @henrique.tx,

Thanks for pointing out the TorizonCore. We are nearly at the end of the project development - so there is no room for switching to TorizonCore. But maybe we could switch for the upcoming project…

Regarding updating, what should I update? The go-1.14.bb recipe (and all the files contained within the directory)? So I tried this but had no luck. It complained with errors…

Is this approach correct? Or is there a better method for updating recipe files?

Hi @Robbie ,

I saw that you used the most recent dunfell version of meta-virtualization, which is commit 35c723774ee06b3c1831f00a2cbf25cbeae132e1 at the time of writing this.

Did you take a look at how we implement Docker in TorizonCore at our meta-toradex-torizon layer? There we have a .bbappend file that downloads a more recent version of Docker CE than the one present by default in the dunfell version of meta-virtualization, along with some additional patches.

We also use an older dunfell version of meta-virtualization for TorizonCore 5, which currently is this one:

You can verify this by downloading our layers for TorizonCore 5 with repo sync, dunfell-5.x.y branch, as instructed here:

See if Docker works if you use our setup for meta-toradex-torizon with this specific version of meta-virtualization. This may be an easier alternative than trying to update the Golang recipe.

Lucas Akira
