I am having trouble using BuildKit. I am using Ubuntu 18.04 with Docker version 19.03.8, build afacb8b7f0
Dockerfile:
FROM ubuntu:18.04
RUN echo hello
RUN echo world
Command:
export DOCKER_BUILDKIT=1
docker build .
Output:
[+] Building 0.4s (4/6)
=> [internal] load build definition from Dockerfile 0.0s
=> => transferring dockerfile: 37B 0.0s
=> [internal] load .dockerignore 0.0s

=> => # hello
unexpected EOF
The seconds echo command is not executed. The same Dockerfile works fine without BuildKit.
