From ba65301c955454e47c3893ca548f18a845a4c4a9 Mon Sep 17 00:00:00 2001 From: baude Date: Wed, 20 Mar 2019 13:00:34 -0500 Subject: podman-remote create|run add the ability to create and run containers via the podman-remote client. we now create an intermediate layer from the the create/run cli flags. the intermediate layer can be converted into a createconfig or into a varlink struct. Once transported, the varlink struct can be converted back to an intermediate layer and then to a createconfig. remote terminals are not supported yet.
