[Amazon Linux 2] docker buildx create & build error (rootless): `mount sysfs:/sys (via /proc/self/fd/6), flags: 0xe: operation not permitted: unknown`

Rez0k commented 1 year ago

Hi,

I am running docker in docker rootless (dind-rootless) on kubernetes cluster (eks cluster with containerd as container runtime). everything is working on dind, but when migrating to dind-rootless I am getting errors while running the commands:

docker buildx create --name ci-builder --config buildkitd.toml --use --driver-opt image=moby/buildkit:v0.10.4-rootless --buildkitd-flags '--security-opt seccomp=unconfined --security-opt apparmor=unconfined --device /dev/fuse --oci-worker-no-process-sandbox --allow-insecure-entitlement security.insecure'

docker buildx build --push --builder ci-builder

I tried running the dind-rootless with the fuse-overlayfs storage driver and nothing changed. I also tried modifying the buildkitd-flags and nothing changed.

Thanks !

Is this Amazon EKS?

I'm also seeing this problem, but on AKS

We also had the same issue. After debugging a bit what helped for us deactivating Istio namespace injection.

Specifying --oci-worker-no-process-sandbox may work (although it seems already specified for the OP's case)
