ContainerD OCI Import

Build and export docker images as OCI for use with containerD on a Raspberry Pi.

Build

Build and export an OCI image with buildx:

docker buildx build --platform=linux/arm/v7 --tag hello -o type=oci,dest=- . > hello.tar

NOTE: If you have buildkit installed, you can use that.

Import

Copy the image to the pi:

scp ./hello.tar pi@raspberrypi.local:

On the pi, import the image with ctr:

sudo ctr -n=example images import hello.tar

NOTE: We use the example namespace, but could just use the default one too.

The image should be available as docker.io/library/hello:latest after imported.

Use

Copy the main.go file to the pi:

scp ./main.go pi@raspberrypi.local:

Build it:

go build main.go

And run it:

sudo ./main

Or build it locally and copy it to the pi:

GOARCH=arm GOOS=linux go build -o main ./main.go
scp ./main pi@raspberrypi.local:
sudo ./main
