How to use extra trusted CA certs when pulling images for a builder

I’m trying to build an image in Openshift 4.2 where my internet has an MITM proxy.

So trying to pull docker images fails during the build with x509 errors.

Is there a way to provide extra trusted CA certificates to the builder?

Warning: Pull failed, retrying in 5s ...

error: build error: failed to pull image: After retrying 2 times, Pull image still failed due to error: while pulling "docker://registry.redhat.io/ubi7-minimal:7.7" as "registry.redhat.io/ubi7-minimal:7.7": Error initializing source docker://registry.redhat.io/ubi7-minimal:7.7: pinging docker registry returned: Get https://registry.redhat.io/v2/: x509: certificate signed by unknown authority
