multi-platform builds fail

[vincer]

Description

When running docker build --platform linux/amd64,linux/arm64 . I get:

ERROR: Multi-platform build is not supported for the docker driver.
Switch to a different driver, or turn on the containerd image store, and try again.
Learn more at https://docs.docker.com/go/build-multi-platform/

Per this issue comment it sounds like this should work out of the box.

buildx says it's using Colima:

NAME/NODE       DRIVER/ENDPOINT   STATUS    BUILDKIT               PLATFORMS
colima*         docker
 \_ colima       \_ colima        running   v0.11.7+435cb77e369c   linux/arm64, linux/amd64, linux/amd64/v2
default                           error
desktop-linux                     error

Cannot load builder default: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
Cannot load builder desktop-linux: Cannot connect to the Docker daemon at unix:///Users/vince/.docker/run/docker.sock. Is the docker daemon running?

I tried recreating the buildx builder, recreating the Colima instance and always get that message which refers me to Docker Desktop docs to enable the "containerd image store". Is there an equivalent step for Colima or some other step I need to take?

This should help

docker buildx create --use --name super-builder

@vincer Edit $HOME/.colima/default/colima.yaml to contain:

# NOTE: value cannot be changed after virtual machine is created.
# Default: qemu
vmType: vz

# Utilise rosetta for amd64 emulation (requires m1 mac and vmType `vz`)
# Default: false
rosetta: true
docker:
  features:
    containerd-snapshotter: true

Then run colima restart and containerd storage should become enabled.

Then run colima restart and containerd storage should become enabled.

you may need to delete ~/.colima/_lima/colima/diffdisk if the restart fails. Had an error that its format was wrong. Deleting it and restarting colima again resolved that.
