Make it possible to specify an image build tool other than docker - a
limitation is that the build tool must be compatible with docker files,
of course. This makes it possible to build an NFD image without the
Docker daemon, for example.
The image build command is specified in a makefile variable and can be
overridden from command line, for example:
$ make IMAGE_BUILD_CMD="buildah bud"
Thanks: Zvonko Kosic for suggesting this
Without correct proxy settings propagated to docker build it is not possible to
build node-feature-discovery from behind a proxy server, e.g. in corporate
networks. This patch fixes the issue by exporting all http(s) proxy related
environment variables as build-time variables.
- Added interface FeatureSource, moved cpuid, rdt and pstate
discovery logic into implementations.
- Updated logging output to make it more machine-readable
(one feature, in label-format, per line).
- Normalized label names (derived from the underlying feature source).
- Added makefile.
- Added command-line argument parsing and proper CLI documentation.
- Added ability to filter the enabled feature sources: cpuid,rdt,pstate.
- Added ability to print the software version and exit.
- Added ability to print the CLI help.
- Updated README.
- Updated dep versions.
- Added -s -w to ldflags.
- Output version label along with discovered feature labels.
- Added sources section to README.
- Normalized README link for pstate
