CRIO runtime spec for OCI v1alpha1 compliance

Question

devs, where can I find the spec for a cri-o runtime cmdline interface to be fully OCI v1alpha1 compliant?

CRI-O supports any OCI compatible runtime. We test with runc and Clear Containers today.

But while playing around with crictl I noticed that cri-o uses runc commands and flags that are nowhere defined within the OCI Runtime Command Line Interface version 1.0.1 e.g the exec command. I tried to get the LXC runtime for cri-o working and noticed that exec is missing from the cmdline.

Thanks for your help!

That is an issue with LXC. The issue with OCI is we rely on commands matching up with the way that runc works.
