Problem Description

Build Image using a Dockerfile with a '--chmod' command throws this error on build:

• the --chmod option requires BuildKit. Refer to https://docs.docker.com/go/buildkit/ to learn how to build images with BuildKit enabled

The image builds fine from the CLI. Buildkit is enabled in daemon.json, but it should be default from Docker v23 and up. I am currently building with Docker v24.

Expected Behavior

The image should build with both docker build and Portainer's build image function.

Actual Behavior

Build Image using a Dockerfile with a '--chmod' command throws this error on build:

• the --chmod option requires BuildKit. Refer to https://docs.docker.com/go/buildkit/ to learn how to build images with BuildKit enabled

Steps to Reproduce

Use the Dockerfile from this repo for testing.
