From 97323808ed57cf52311a80c55339f8927614b7f0 Mon Sep 17 00:00:00 2001 From: Matthew Heon Date: Mon, 17 Feb 2020 16:49:59 -0500 Subject: Add network options to podman pod create Enables most of the network-related functionality from `podman run` in `podman pod create`. Custom CNI networks can be specified, host networking is supported, DNS options can be configured. Also enables host networking in `podman play kube`. Fixes #2808 Fixes #3837 Fixes #4432 Fixes #4718 Fixes #4770 Signed-off-by: Matthew Heon --- libpod/options.go | 43 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 43 insertions(+) (limited
