We call `modprobe -n` to check if mpls modules are available to be loaded. We do this as normal user, to only ask for root permissions if we are actually loading the module. This breaks if `modprobe` is in `/sbin` and normal users don't have sbin in path. So add `/sbin` to the search path to work around this.

Topotests in Docker
Quickstart
If you have Docker installed, you can run the topotests in Docker. The easiest way to do this, is to use the make targets from this repository.
Your current user needs to have access to the Docker daemon. Alternatively you can run these commands as root.
make topotests-build
make topotests
The first command will build a docker image with all the dependencies needed to run the topotests.
The second command will spawn an instance of this image, compile FRR inside of it, and run the topotests.
Advanced Usage
Internally, the topotests make target uses a shell script to spawn the docker container.
There are several environment variables which can be used to modify the behavior
of the script, these can be listed by calling it with -h:
./tests/topotests/docker/frr-topotests.sh -h
For example, a volume is used to cache build artifacts between multiple runs
of the image. If you need to force a complete recompile, you can set TOPOTEST_CLEAN:
TOPOTEST_CLEAN=1 ./tests/topotests/docker/frr-topotests.sh
By default, frr-topotests.sh will build frr and run pytest. If you append
arguments and the first one starts with / or ./, they will replace the call to
pytest. If the appended arguments do not match this patttern, they will be provided to
pytest as arguments.
So, to run a specific test with more verbose logging:
./tests/topotests/docker/frr-topotests.sh -vv -s all-protocol-startup/test_all_protocol_startup.py
And to compile FRR but drop into a shell instead of running pytest:
./tests/topotests/docker/frr-topotests.sh /bin/bash
