From 1d10ca739f3599b9bd746783ad15c8f51ce9f75c Mon Sep 17 00:00:00 2001 From: cdoern Date: Fri, 25 Jun 2021 14:26:33 -0400 Subject: Created scp.go image_scp_test.go and podman-image-scp.1.md added functionality for image secure copying from local to remote. Also moved system connection add code around a bit so functions within that file can be used by scp.
