Open Container Initiative (OCI) started in 2015 to make different implementations of container runtimes and images compliant with well-defined specifications. Together with other folks at Kinvolk, I have been involved in various OCI projects since months, and encountered various issues that occur in runtime specs and runtime-tools for verification. Since we live in a real world, not everything works well as expected. I’m going to talk about practical issues, and possible ways to get it improved.
