Hello, this is the Falco tester container.
How to use.
...
The default commands for the Falco tester image reports usage and environment info.
* docker run falcosecurity/falco-tester
* docker run falcosecurity/falco-tester usage
It supports bash.
* docker run -ti falcosecurity/falco-tester:chore-travis bash
To run Falco regression tests you need to provide:
- the docker socket
- the boot directory
- the source directory
- the directory where Falco has been built
- the environment variable FALCO_VARIABLE set to the value obtained during the Falco's build
Assuming you are running it from the Falco root directory, you can run it as follows.
* docker run -v /boot:/boot:ro -v /var/run/docker.sock:/var/run/docker.sock -v $PWD/..:/source -v $PWD/build:/build -e FALCO_VERSION=<current_falco_version> falcosecurity/falco-tester test
How to build.
...
* cd docker/builder && DOCKER_BUILDKIT=1 docker build -t falcosecurity/falco-tester .
Environment.
* ...
* python ${pythonversion}
* ${pipversion}
* ${dockerversion}
