Custom Operator and grpc runtime

This example shows how to run a gadget in a remote instance of Inspektor Gadget and how to get its output by implementing a custom operator.

How to run

ig needs to be running in daemon mode in the same machine as this example:

$ sudo ig daemon --host tcp://127.0.0.1:8888
INFO[0000] starting Inspektor Gadget daemon at "tcp://127.0.0.1:8888"

Run the binary. In this root is not needed because the all privileged operations are done by the ig process.

$ go run .
