An example of how to set up a connection from MacOS to inside the Podman Host VM

podman-socket.sh

#!/usr/bin/env bash
set -o errexit
set -o nounset
set -o pipefail

# run script with TRACE=1 ... to enable debugging
if [[ "${TRACE-0}" == "1" ]]; then
    set -o xtrace
fi

PODMAN_PORT=$(podman system connection list --format=json | jq '.[0].URI' | sed -E 's|.+://.+@.+:([[:digit:]]+)/.+|\1|')
PODMAN_INTERNAL_UID=$(podman system info --format=json | jq '.host.idMappings.uidmap[0].host_id')

rm -f /tmp/podman.sock
ssh -v -i ~/.ssh/podman-machine-default  \
-p "$PODMAN_PORT" \
-L "/tmp/podman.sock:/run/user/$PODMAN_INTERNAL_UID/podman/podman.sock" \
-N core@localhost
