fluent-package-builder

About fluent-package-builder

fluent-package-builder (formerly known as td-agent-builder, it was renamed at Aug, 2021) is a new build system for td-agent which aims to replace the traditional build system omnibus-td-agent since it has several problems due to Omnibus's limitations.

NOTE: Discussed why re-branding is required Rebranding td-agent-builder

Changes from Treasure Agent 3

  • Use system libraries: e.g. openssl
  • Remove libraries for 3rd party gems: e.g. postgresql
  • Remove embedded directory by omnibus
    • Use /opt/td-agent/bin/fluent-cat instead of /opt/td-agent/embedded/bin/fluent-cat
  • Update core components: ruby, jemalloc and more
  • Add td-agent-apt-source deb package for maintaining apt-line and keyring
    • Download it and install by apt install, then you can install td-agent via apt install td-agent.
    • td-agent-apt-source deb package is created to install td-agent easily. Currently it points to td-agent 4 apt-line.

See also this issue for omnibus problems.

Prerequisites

For building .rpm & .deb packages

  • Any host OS that is supported by Docker
    • Debian buster or Ubuntu 18.04 are recommended
  • Docker
  • Ruby 2.5 or later
  • Bundler 2.2.0 or later
  • Git

For building Windows package (.msi)

After installed above software, you need to enable additional features from powershell (as admin).

dism.exe /online /enable-feature /featurename:Microsoft-Hyper-V /all /norestart
dism.exe /online /enable-feature /featurename:Containers /all /norestart

Then restart Windows.

For building macOS package (.dmg)

  • macOS 10.15 (Catalina)
  • Ruby 2.5 or later
  • Bundler 2.2.0 or later
  • Git

How to build .rpm package

% rake yum:build

By default, yum repositories for following platforms will be built under td-agent/yum/repositories/ directory:

  • CentOS 6 (x86_64)
  • CentOS 7 (x86_64)
  • CentOS 8 (x86_64)

You can choose target platforms by YUM_TARGETS environment variable like this:

% rake yum:build YUM_TARGETS="centos-6,centos-7,centos-8"

You can find other supported platforms under td-agent/yum directory.

Note for AArch64 platforms

You can also build packages for AArch64 platforms like this:

% rake yum:build YUM_TARGETS="centos-8-aarch64"

But if you use older GNU/Linux platforms (e.g. Ubuntu 18.04 or before) as your host OS, you need to copy qemnu-aarch64-static into the base directory of the target:

% export TARGET_BASE="centos-8"
% sudo apt install qemu-user-static
% cd /path/to/fluent-package-builder
% cp /usr/bin/qemu-aarch64-static td-agent/yum/${TARGET_BASE}
% rake yum:build YUM_TARGETS="${TARGET_BASE}-aarch64"

Note for ppc64le platform

You can also build packages for ppc64le platform like this:

% rake yum:build YUM_TARGETS="centos-8-ppc64le"

But if you use older GNU/Linux platforms (e.g. Ubuntu 18.04 or before) as your host OS, you need to copy qemnu-ppc64le-static into the base directory of the target:

% export TARGET_BASE="centos-8"
% sudo apt install qemu-user-static
% cd /path/to/fluent-package-builder
% cp /usr/bin/qemu-ppc64le-static td-agent/yum/${TARGET_BASE}
% rake yum:build YUM_TARGETS="${TARGET_BASE}-ppc64le"

How to build .deb package

% rake apt:build

By default, apt repositories for following platforms will be built under td-agent/apt/repositories/ directory:

  • Debian 10 "Buster" (x86_64)
  • Ubuntu 20.04 LTS "Focal Fossa" (x86_64)
  • Ubuntu 18.04 LTS "Bionic Beaver" (x86_64)
  • Ubuntu 16.04 LTS "Xenial Xerus" (x86_64)

You can choose target platforms by APT_TARGETS environment variable like this:

% rake apt:build APT_TARGETS="debian-buster,ubuntu-bionic"

You can find other supported platforms under td-agent/apt directory.

Note for AArch64 platforms

You can also built packages for AArch64 platforms like this:

% rake apt:build APT_TARGETS="ubuntu-bionic-arm64"

But if you use older GNU/Linux platforms (e.g. Ubuntu 18.04 or before) as your host OS, you need to copy qemnu-aarch64-static into the base directory of the target:

% export TARGET_BASE="ubuntu-bionic"
% sudo apt install qemu-user-static
% cd /path/to/fluent-package-builder
% cp /usr/bin/qemu-aarch64-static td-agent/apt/${TARGET_BASE}
% rake apt:build APT_TARGETS="${TARGET_BASE}-arm64"

How to build .msi package

% rake msi:build

A td-agent-${version}-x64.msi package will be built under td-agent/msi directory.

Note for Windows package

You can use with MSYS2 for C extension gem building.

MSI included Ruby can detect MSYS2 environment. So, you can install C extension included gem with MSYS2.

e.g.)

Prepare C extension gem building environment:

cmd> ridk install 2
...
cmd> ridk install 3

Install gem via ridk exec td-agent-gem install:

cmd> ridk exec td-agent-gem install winevt_c

How to build .dmg package

% rake dmg:selfbuild

A td-agent-${version}.dmg package will be built under td-agent/dmg directory.

Note for macOS package

GitHub Actions' built package is ready to run on macOS 10.15 (Catalina).

Be sure to permit to be authrized for for assistive access. In System Preferences > Security & Privacy > Privacy > Accessibility, you should permit Terminal.app there.

NOTE: Since authorization is at the application level on Terminal.app, it allows any script run from Terminal.app to perform GUI scripting.

How to bump up the package version

  • Edit td-agent/config.rb to choose Ruby & Fluentd versions
  • Edit Gemfile and update .lock files
    • cd td-agent && rake lockfile:update
  • Bump up the versions of rpm & deb packages by the following command:
% cd td-agent
% rake version:update
% git diff  # Check the change log
% git commit -a
  • Build packages
% rake apt:build
% rake yum:build
% rake msi:build

Note for bump up the package version

It assumes that Gemfile works with Bundler's multiplatform feature, so bundler must be 2.2.0 or later.
