First, you need libfluent-bit.so Alien::FluentBit helps you with this by building one from source. The binary dist from github.com/fluent/fluent-bit currently does not work with perl without adding the library to LD_PRELOAD which is not a great solution.
apt-get install cmake flex bison m4 # not required, but speeds things up
cpanm Alien::FluentBit
Now you can install the module:
cpanm Fluent-LibFluentBit-0.02.tar.gz
or:
tar -xf Fluent-LibFluentBit-0.02.tar.gz
cd Fluent-LibFluentBit-0.02
perl Makefile.PL
make
make test
make install
Download or checkout the source code, then:
dzil --authordeps | cpanm
dzil test
To build and run single unit tests, use the 'dtest' script:
./dtest t/10-output-to-datadog.t
To build and install a trial version, use
V=0.02_01 dzil build
cpanm Fluent-LibFluentBit-0.02_01.tar.gz
