The AF doesnt have the concept of a baseline scan, it runs the plan you specify.
The blog explains that is you run the baseline with a mapped drive then it will out put a plan for you - this is the plan it uses.
So
will result in a "zap.yaml" file being created in your cwd.
You can run the plan again using:
docker run -v $(pwd):/zap/wrk/:rw -t owasp/zap2docker-weekly zap.sh -cmd -autorun /zap/wrk/zap.yaml
If you use the stable release then you will also need to install the passive scan beta rules:
docker run -v $(pwd):/zap/wrk/:rw -t owasp/zap2docker-stable zap.sh -cmd -addoninstall pscanrulesBeta -autorun /zap/wrk/zap.yaml
That make sense?
