Fluent Bit is compatible with latest Apple macOS system on x86_64 and Apple Silicon M1 architectures. At the moment there is only an official supported package on x86_64 but you can build it from source as well by following the instructions below.
Installation Packages
The packages can be found here: https://packages.fluentbit.io/macos/
Requirements
For the next steps, you will need to have Homebrew installed in your system. If is not there, you can install it with the following command:
Copy /bin/bash -c "$( curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh )" Installing from Homebrew
The Fluent Bit package on Homebrew is not officially supported, but should work for basic use cases and testing. It can be installed using:
Copy brew install fluent-bit Compile from Source
Install build dependencies
Run the following brew command in your terminal to retrieve the dependencies:
Copy brew install git cmake openssl bison Get the source and build it
Grab a fresh copy of the Fluent Bit source code (upstream):
Copy git clone https://github.com/fluent/fluent-bit
cd fluent-bit Optionally, if you want to use a specific version, just checkout to the proper tag. If you want to use v1.8.13 just do:
In order to prepare the build system, we need to expose certain environment variables so Fluent Bit CMake build rules can pick the right libraries:
Copy export OPENSSL_ROOT_DIR = ` brew --prefix openssl `
export PATH = ` brew --prefix bison ` /bin:$PATH Change to the build/ directory inside the Fluent Bit sources:
Build Fluent Bit. Note that we are indicating to the build system "where" the final binaries and config files should be installed:
Copy cmake -DFLB_DEV=on -DCMAKE_INSTALL_PREFIX=/opt/fluent-bit ../
make -j 16 Install Fluent Bit to the directory specified above. Note that this requires root privileges due to the directory we will write information to:
The binaries and configuration examples can be located at /opt/fluent-bit/.
Create macOS installer from source
Grab a fresh copy of the Fluent Bit source code (upstream):
Copy git clone https://github.com/fluent/fluent-bit
cd fluent-bit Optionally, if you want to use a specific version, just checkout to the proper tag. If you want to use v1.9.2 just do:
In order to prepare the build system, we need to expose certain environment variables so Fluent Bit CMake build rules can pick the right libraries:
Copy export OPENSSL_ROOT_DIR = ` brew --prefix openssl `
export PATH = ` brew --prefix bison ` /bin:$PATH And then, creating the specific macOS SDK target (For example, specifying macOS Big Sur (11.3) SDK environment):
Copy export MACOSX_DEPLOYMENT_TARGET = 11.3 Change to the build/ directory inside the Fluent Bit sources:
Build the Fluent Bit macOS installer.
Copy cmake -DCPACK_GENERATOR=productbuild -DCMAKE_INSTALL_PREFIX=/opt/fluent-bit ../
make -j 16
cpack -G productbuild Then, macOS installer will be generated as:
Copy CPack: Create package using productbuild
CPack: Install projects
CPack: - Run preinstall target for: fluent-bit
CPack: - Install project: fluent-bit []
CPack: - Install component: binary
CPack: - Install component: library
CPack: - Install component: headers
CPack: - Install component: headers-extra
CPack: Create package

CPack: - package: /Users/fluent-bit-builder/GitHub/fluent-bit/build/fluent- bit-1.9.2-apple.pkg generated. Finally, fluent-bit-<fluent-bit version>-(intel or apple).pkg will be generated.
The created installer will put binaries at /opt/fluent-bit/.
Running Fluent Bit
To make the access path easier to Fluent Bit binary, in your terminal extend the PATH variable:
Copy export PATH = /opt/fluent-bit/bin:$PATH Now as a simple test, try Fluent Bit by generating a simple dummy message which will be printed to the standard output interface every 1 second:
Copy fluent-bit -i dummy -o stdout -f 1 You will see an output similar to this:
Copy Fluent Bit v1.9.0
