podman: Podman Machine on Mac: podman build --net doesn't work

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind bug

Description

I’m using podman machine on a mac. I have the requirement to spawn a container which is available in an own network and accessible for container images during build (it’s an authentication proxy that handles all credential / ssl stuff so that I don’t need to pass it to the image to build). Creating the network for that container works, but referencing it using --net when calling podman build does not.

Steps to reproduce the issue:

podman network create esc

Tried to build with

podman build --net=esc -t something .

Describe the results you received:

Error: checking network namespace: stat esc: no such file or directory

podman network ls:
NETWORK ID    NAME        VERSION     PLUGINS
2f259bab93aa  podman      0.4.0       bridge,podman-machine,portmap,firewall,tuning
177b7cb06867  esc         0.4.0       bridge,portmap,firewall,tuning,dnsname,podman-machine

Describe the results you expected: A successful build =)

Additional information you deem important (e.g. issue happens only occasionally):

• always happens, with --net and --network.

Have you tested with the latest version of Podman and have you checked the Podman Troubleshooting Guide? (https://github.com/containers/podman/blob/master/troubleshooting.md)

No, can only use the brew version provided on my mac.

Additional environment details (AWS, VirtualBox, physical, etc.): Just a podman machine instance with qemu.
