To allow for a more portable build environment, create a builder image
that is based on centos 6 with devtoolset-2 for a refrence g++.
In that image, install all required packages and run a script that can
either run cmake or make.
The image depends on the following parameters:
FALCO_VERSION: the version to give any built packages
BUILD_TYPE: Debug or Release
BUILD_DRIVER/BPF: whether or not to build the kernel module/bpf program when
building. This should usually be OFF, as the kernel module would be
built for the files in the centos image, not the host.
BUILD_WARNINGS_AS_ERRORS: consider all build warnings fatal
MAKE_JOBS: passed to the -j argument of make
A typical way to run this builder is the following. Assumes you have
checked out falco and sysdig to directories below /home/user/src, and
want to use a build directory of /home/user/build/falco:
$ docker run --user $(id -u):$(id -g) -v /etc/passwd:/etc/passwd:ro -e MAKE_JOBS=4 -it -v /home/user/src:/source -v /home/user/build/falco:/build falco-builder cmake
$ docker run --user $(id -u):$(id -g) -v /etc/passwd:/etc/passwd:ro -e MAKE_JOBS=4 -it -v /home/user/src:/source -v /home/user/build/falco:/build falcosecurity/falco-builder package
