# Fluent Bit Packaging

This directory contains files to support building and releasing Fluent Bit.

For PRs, add the `ok-package-test` label to trigger an automated build of all supported Linux, macOS, Windows and container image targets to verify a PR correctly builds for all supported platforms.
This can take some time to complete so is only triggered via the label on-demand.

## Linux

The [`distros`](./distros/) directory contains OCI container definitions used to build [Fluent Bit](http://fluentbit.io) Linux packages for different distros, the following table describe the supported targets:

| Distro        |   Version / Code Name     | Arch    | Target Option            |

These container images are intended to be built from the root of this repo to build the locally checked out/updated version of the source easily for any target.

### Usage

The _build.sh_ script can be used to build packages for a specific target, the command understand the following format:

```shell
./build.sh -d DISTRO
```

Replace `DISTRO` with the `Target option` column above.

All Linux builds happen in a container so can be run on any supported platform with QEMU installed and a container runtime.

## Windows

Windows builds are carried out by the [dedicated workflow](../.github/workflows/call-build-windows.yaml) in CI.
This builds using the standard CMake process on a dedicated Windows runner within Github actions.
The steps involved and additional requirements can all be found there.

## macOS

Windows builds are carried out by the [dedicated workflow](../.github/workflows/call-build-macos.yaml) in CI.
This builds using the standard CMake process on a dedicated macOS runner within Github actions.
The steps involved and additional requirements can all be found there.
