* Read kubernetes version from environment
Set kubernetes version to the value of the environment variable `KUBE_BENCH_VERSION` if it is defined and the flag `--version` is not specified on the kube-bench command line.
The command line flag `--version` takes precedence of the environment variable `KUBE_BENCH_VERSION` if both are defined.
* Add info about KUBE_BENCH_VERSION to README
The root command will run node checks and if possible master checks.
I've also added some Makefile targets to improve local testing and improve the documentation.
This is caused by a command in the audit pipeline (for example
ps -ef | grep kube-apiserver) failing. The causes of this failure
in my testing is usually a missing config file.
Extensive refactor and correction in verification code to check for
config files and binaries.
Replace joncalhoun/pipes with implementation using exec.Cmds so errors
are visible and can be handled when audit pipeline commands fail.
Change some audit commands
from: ps -ef | grep <cmd> | grep -v
to: ps -C <something> -o comm,args --no-headers
which is simpler to work with.
* Replace the default help text
* Readme file, including the test config format documentation
* Typo
* Warn if config files / executables aren't found
* Ignore original name of executable (as per current README)
* Update tests to avoid failing on stat of a non-existant file
* Add a makefile for ease of build
