From 338d521782727daca90efc2601b16502626aa53c Mon Sep 17 00:00:00 2001 From: Matthew Heon Date: Tue, 28 Jul 2020 16:22:48 -0400 Subject: Re-create OCI runtimes by path when it is missing When an OCI runtime is given by full path, we need to ensure we use the same runtime on subsequent use. Unfortunately, users are often not considerate enough to use the same `--runtime` flag every time they invoke runtime - and if the runtime was not in containers.conf, that means we don't have it stored inn the libpod Runtime. Fortunately, since we have the full path, we can initialize the OCI runtime for use at the point where we pull the container from the database.
