Additional info: - OpenShift supports specific docker version. OCP 3.9 supports docker 1.13, so we would like you to backport it into docker-1.13.
Podman build now has support for this. Should be in podman 0.12.1
Test with the steps in comment 1 with podman-0.12.1.2-2.git9551f6b.el7.x86_64: # podman build -t test . STEP 1: FROM busybox STEP 2: RUN echo $foo test --> e6736a73421a23d68d7100ea2c42a54ce42e55e32781cc9b8a5e0bb65ed640d0 STEP 3: COMMIT test [Warning] One or more build-args [foo] were not consumed So set this to verified.
