AM4378: Running Docker Engine and small hello-world container

Mahesh Gaikwad
Prodigy 190 points
Part Number: AM4378

I am trying to get docker-container on AM4378.

Have created image with docker-ce enabled and when I check docker --version on target i do see docker-engine available

However when i try to get a image running[basic hello-world], I see various kernel configuration missing.

I added few based on my reading of this (Please find attached kernel config fragments I added)

But with this too, I get some more configuration missing.

I would like to know the exact kernel fragments I need to enable to run a docker image

I am using linux-4.19 kernel.

Would like to know, if this is even possible on Am437x and what needs to be done to enable this

TIA

    Hi Mahesh,

    our current TI SDK for AM437x v8.2 should support Docker right out of the box. Please download the SDK (https://www.ti.com/tool/PROCESSOR-SDK-AM437X) and try programming the tisdk-docker-rootfs-image-am437x-evm.wic.xz SD card image and see if this works for you. If it does, you can then go into the associated Yocto sources and figure out how it works / what makes it work, and apply that to your scenario as needed.

    Thanks for the response.

    As suggested u tried the "tisdk-docker-*" image.

    When i try to get a docker image i get errors asking to check if docker is running

    I tried couple of systemctl commands too to stat the docker but that too didnt help

    Attached is the logs of what i tried and the errors i see.

    Let me know your thoughts

    By the way i was able to get the docker image running on another hardware of mine which has Am62x processor.

    But i am looking to see if i can get this with AM4378. I am trying this on AM437x-SK-EVM
