Shim

• Debug mode
• Enable trace support

This project implements a shim called kata-shim for the Kata Containers project.

The shim runs in the host environment, handling standard I/O and signals on behalf of the container process which runs inside the virtual machine.

Debug mode

To enable agent debug output to the system journal, run with -debug.

Enable trace support

To generate OpenTracing traces using Jaeger, run with -trace.

Note:

Since the Jaeger package used by the shim needs to communicate trace information to the Jaeger agent, it is necessary to ensure the shim runs in the same network namespace as the Jaeger agent.
