Dev Environment

Linux Dev Environment

Based on CentOS 7, we have an early draft available inside the Icinga Vagrant boxes: centos7-dev.

If you’re compiling Icinga 2 natively without any virtualization layer in between, this usually is faster. This is also the reason why developers on macOS prefer native builds over Linux or Windows VMs. Don’t forget to test the actual code on Linux later! Socket specific stuff like epoll is not available on Unix kernels.

Depending on your workstation and environment, you may either develop and run locally, use a container deployment pipeline or put everything in a high end resource remote VM.

Fork https://github.com/Icinga/icinga2 into your own repository, e.g. https://github.com/dnsmichi/icinga2.

Create two build directories for different binary builds.

• debug contains the debug build binaries. They contain more debug information and run tremendously slower than release builds from packages. Don’t use them for benchmarks.
• release contains the release build binaries, as you would install them on a live system. This helps comparing specific scenarios for race conditions and more.

mkdir -p release debug

Proceed with the specific distribution examples below. Keep in mind that these instructions are best effort and sometimes out-of-date. Git Master may contain updates.

• CentOS 7
• Debian 10 Buster
• Ubuntu 18 Bionic

CentOS 7

yum -y install gdb vim git bash-completion htop

yum -y install rpmdevtools ccache \
 cmake make gcc-c++ flex bison \
 openssl-devel boost169-devel systemd-devel \
 mysql-devel postgresql-devel libedit-devel \
 libstdc++-devel

groupadd icinga
groupadd icingacmd
useradd -c "icinga" -s /sbin/nologin -G icingacmd -g icinga icinga

ln -s /bin/ccache /usr/local/bin/gcc
ln -s /bin/ccache /usr/local/bin/g++

git clone https://github.com/icinga/icinga2.git && cd icinga2

The debug build binaries contain specific code which runs slower but allows for better debugging insights.

For benchmarks, change CMAKE_BUILD_TYPE to RelWithDebInfo and build inside the release directory.

First, off export some generics for Boost.

export I2_BOOST="-DBoost_NO_BOOST_CMAKE=TRUE -DBoost_NO_SYSTEM_PATHS=TRUE -DBOOST_LIBRARYDIR=/usr/lib64/boost169 -DBOOST_INCLUDEDIR=/usr/include/boost169 -DBoost_ADDITIONAL_VERSIONS='1.69;1.69.0'"

Second, add the prefix path to it.

export I2_GENERIC="$I2_BOOST -DCMAKE_INSTALL_PREFIX=/usr/local/icinga2"

Third, define the two build types with their specific CMake variables.

export I2_DEBUG="-DCMAKE_BUILD_TYPE=Debug -DICINGA2_UNITY_BUILD=OFF $I2_GENERIC"
export I2_RELEASE="-DCMAKE_BUILD_TYPE=RelWithDebInfo -DICINGA2_WITH_TESTS=ON -DICINGA2_UNITY_BUILD=ON $I2_GENERIC"

Fourth, depending on your likings, you may add a bash alias for building, or invoke the commands inside:

alias i2_debug="cd /root/icinga2; mkdir -p debug; cd debug; cmake $I2_DEBUG ..; make -j2; sudo make -j2 install; cd .."
alias i2_release="cd /root/icinga2; mkdir -p release; cd release; cmake $I2_RELEASE ..; make -j2; sudo make -j2 install; cd .."

This is taken from the centos7-dev Vagrant box.

The source installation doesn’t set proper permissions, this is handled in the package builds which are officially supported.

chown -R icinga:icinga /usr/local/icinga2/var/

/usr/local/icinga2/lib/icinga2/prepare-dirs /usr/local/icinga2/etc/sysconfig/icinga2

Debian 10

Debian Buster doesn’t need updated Boost packages from packages.icinga.com, the distribution already provides 1.66+. For older versions such as Stretch, include the release repository for packages.icinga.com as shown in the setup instructions.

macOS Dev Environment

It is advised to use Homebrew to install required build dependencies. Macports have been reported to work as well, typically you’ll get more help with Homebrew from Icinga developers.

The idea is to run Icinga with the current user, avoiding root permissions. This requires at least v2.11.

Note

This is a pure development setup for Icinga developers reducing the compile time in contrast to VMs. There are no packages, startup scripts or dependency management involved.

macOS agents are not officially supported.

macOS uses its own TLS implementation, Icinga relies on extra OpenSSL packages requiring updates apart from vendor security updates.

Requirements

Explicitly use OpenSSL 1.1.x, older versions are out of support.

brew install ccache boost cmake bison flex openssl@1.1 mysql-connector-c++ postgresql libpq

ccache

sudo mkdir /opt/ccache

sudo ln -s `which ccache` /opt/ccache/clang
sudo ln -s `which ccache` /opt/ccache/clang++

vim $HOME/.bash_profile

# ccache is managed with symlinks to avoid collision with cgo
export PATH="/opt/ccache:$PATH"

source $HOME/.bash_profile

Builds

Icinga is built as release (optimized build for packages) and debug (more symbols and details for debugging). Debug builds typically run slower than release builds and must not be used for performance benchmarks.

The preferred installation prefix is /usr/local/icinga/icinga2. This allows to put e.g. Icinga Web 2 into the /usr/local/icinga directory as well.

mkdir -p release debug

export I2_USER=$(id -u -n)
export I2_GROUP=$(id -g -n)
export I2_GENERIC="-DCMAKE_INSTALL_PREFIX=/usr/local/icinga/icinga2 -DICINGA2_USER=$I2_USER -DICINGA2_GROUP=$I2_GROUP -DOPENSSL_INCLUDE_DIR=/usr/local/opt/openssl@1.1/include -DOPENSSL_SSL_LIBRARY=/usr/local/opt/openssl@1.1/lib/libssl.dylib -DOPENSSL_CRYPTO_LIBRARY=/usr/local/opt/openssl@1.1/lib/libcrypto.dylib -DICINGA2_PLUGINDIR=/usr/local/sbin -DICINGA2_WITH_PGSQL=OFF -DCMAKE_EXPORT_COMPILE_COMMANDS=ON"
export I2_DEBUG="-DCMAKE_BUILD_TYPE=Debug -DICINGA2_UNITY_BUILD=OFF $I2_GENERIC"
export I2_RELEASE="-DCMAKE_BUILD_TYPE=RelWithDebInfo -DICINGA2_WITH_TESTS=ON -DICINGA2_UNITY_BUILD=ON $I2_GENERIC"

cd debug
cmake $I2_DEBUG ..
cd ..

make -j4 -C debug
make -j4 install -C debug

In order to run Icinga without any path prefix, and also use Bash completion it is advised to source additional things into the local dev environment.

export PATH=/usr/local/icinga/icinga2/sbin/:$PATH

test -f /usr/local/icinga/icinga2/etc/bash_completion.d/icinga2 && source /usr/local/icinga/icinga2/etc/bash_completion.d/icinga2

Build Aliases

This is derived from dnsmichi’s flavour and not generally best practice.

vim $HOME/.bash_profile

export I2_USER=$(id -u -n)
export I2_GROUP=$(id -g -n)
export I2_GENERIC="-DCMAKE_INSTALL_PREFIX=/usr/local/icinga/icinga2 -DICINGA2_USER=$I2_USER -DICINGA2_GROUP=$I2_GROUP -DOPENSSL_INCLUDE_DIR=/usr/local/opt/openssl@1.1/include -DOPENSSL_SSL_LIBRARY=/usr/local/opt/openssl@1.1/lib/libssl.dylib -DOPENSSL_CRYPTO_LIBRARY=/usr/local/opt/openssl@1.1/lib/libcrypto.dylib -DICINGA2_PLUGINDIR=/usr/local/sbin -DICINGA2_WITH_PGSQL=OFF -DCMAKE_EXPORT_COMPILE_COMMANDS=ON"

export I2_DEBUG="-DCMAKE_BUILD_TYPE=Debug -DICINGA2_UNITY_BUILD=OFF $I2_GENERIC"
export I2_RELEASE="-DCMAKE_BUILD_TYPE=RelWithDebInfo -DICINGA2_WITH_TESTS=ON -DICINGA2_UNITY_BUILD=ON $I2_GENERIC"

alias i2_debug="mkdir -p debug; cd debug; cmake $I2_DEBUG ..; make -j4; make -j4 install; cd .."
alias i2_release="mkdir -p release; cd release; cmake $I2_RELEASE ..; make -j4; make -j4 install; cd .."

export PATH=/usr/local/icinga/icinga2/sbin/:$PATH
test -f /usr/local/icinga/icinga2/etc/bash_completion.d/icinga2 && source /usr/local/icinga/icinga2/etc/bash_completion.d/icinga2


source $HOME/.bash_profile

Permissions

make install doesn’t set all required permissions, override this.

chown -R $I2_USER:$I2_GROUP /usr/local/icinga/icinga2

Run

Start Icinga in foreground.

icinga2 daemon

Reloads triggered with HUP or cluster syncs just put the process into background.

Plugins

brew install monitoring-plugins

sudo vim /usr/local/icinga/icinga2/etc/icinga2/constants.conf

const PluginDir = "/usr/local/sbin"

Backends: Redis

brew install redis
brew services start redis

Databases: MariaDB

brew install mariadb
mkdir -p /usr/local/etc/my.cnf.d
brew services start mariadb

mysql_secure_installation

vim $HOME/.my.cnf

[client]
user = root

sudo -i
ln -s /Users/michi/.my.cnf $HOME/.my.cnf
exit

mysql -e 'create database icinga;'
mysql -e "grant all on icinga.* to 'icinga'@'localhost' identified by 'icinga';"
mysql icinga < $HOME/dev/icinga/icinga2/lib/db_ido_mysql/schema/mysql.sql

API

icinga2 api setup
cd /usr/local/icinga/icinga2/var/lib/icinga2/certs
HOST_NAME=mbpmif.int.netways.de
icinga2 pki new-cert --cn ${HOST_NAME} --csr ${HOST_NAME}.csr --key ${HOST_NAME}.key
icinga2 pki sign-csr --csr ${HOST_NAME}.csr --cert ${HOST_NAME}.crt
echo "const NodeName = \"${HOST_NAME}\"" >> /usr/local/icinga/icinga2/etc/icinga2/constants.conf

Web

While it is recommended to use Docker or the Icinga Web 2 development VM pointing to the shared IDO database resource/REST API, you can also install it locally on macOS.

The required steps are described in this script.

Windows Dev Environment

The following sections explain how to setup the required build tools and how to run and debug the code.

TL;DR

If you’re going to setup a dev environment on a fresh Windows machine and don’t care for the details,

1. ensure there are 35 GB free space on C:
2. run the following in an administrative Powershell:
3. Enable-WindowsOptionalFeature -FeatureName "NetFx3" -Online (reboot when asked!)
4. powershell -NoProfile -ExecutionPolicy Bypass -Command "Invoke-Expression (New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com/Icinga/icinga2/master/doc/win-dev.ps1')" (will take some time)

This installs everything needed for cloning and building Icinga 2 on the command line (Powershell) as follows:

(Don’t forget to open a new Powershell window to be able to use the newly installed Git.)

git clone https://github.com/Icinga/icinga2.git
cd .\icinga2\
mkdir build
cd .\build\

& "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin\cmake.exe" `
  -DBoost_INCLUDE_DIR=C:\local\boost_1_71_0-Win64 `
  -DBISON_EXECUTABLE=C:\ProgramData\chocolatey\lib\winflexbison3\tools\win_bison.exe `
  -DFLEX_EXECUTABLE=C:\ProgramData\chocolatey\lib\winflexbison3\tools\win_flex.exe `
  -DICINGA2_WITH_MYSQL=OFF -DICINGA2_WITH_PGSQL=OFF ..

& "C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\MSBuild\Current\Bin\MSBuild.exe" .\icinga2.sln

Building icinga2.sln via Visual Studio itself seems to require a reboot after installing the build tools and building once via command line.

Chocolatey

Open an administrative command prompt (Win key, type “cmd”, right-click and “run as administrator”) and paste the following instructions:

@powershell -NoProfile -ExecutionPolicy Bypass -Command "iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin

Git, Posh and Vim

In case you are used to vim, start a new administrative Powershell:

choco install -y vim

The same applies for Git integration in Powershell:

choco install -y poshgit

In order to fix the colors for commands like git status or git diff, edit $HOME/.gitconfig in your Powershell and add the following lines:

vim $HOME/.gitconfig

[color "status"]
    changed = cyan bold
    untracked = yellow bold
    added = green bold
    branch = cyan bold
    unmerged = red bold

[color "diff"]
    frag = cyan
    new = green bold
    commit = yellow
    old = red white

[color "branch"]
  current = yellow reverse
  local = yellow
  remote = green bold
  remote = red bold

Visual Studio

Thanks to Microsoft they’ll now provide their Professional Edition of Visual Studio as community version, free for use for open source projects such as Icinga. The installation requires ~9GB disk space. Download the web installer and start the installation.

Note: Only Visual Studio 2019 is covered here. Older versions are not supported.

You need a free Microsoft account to download and also store your preferences.

Install the following complete workloads:

• C++ Desktop Development
• .NET Desktop Development

In addition also choose these individual components on Visual Studio:

• .NET
  • .NET Framework 4.x targeting packs
  • .NET Framework 4.x.y SDKs
• Code tools
  • Git for Windows
  • GitHub Extension for Visual Studio
  • NuGet package manager
• Compilers, build tools and runtimes

After a while, Visual Studio will be ready.

Style Guide for Visual Studio

Navigate into Tools > Options > Text Editor and repeat the following for

• C++
• C#

Navigate into Tabs and set:

• Indenting: Smart (default)
• Tab size: 4
• Indent size: 4
• Keep tabs (instead of spaces)

Flex and Bison

Install it using chocolatey:

choco install -y winflexbison

Chocolatey installs these tools into the hidden directory C:\ProgramData\chocolatey\lib\winflexbison\tools.

OpenSSL

Icinga 2 requires the OpenSSL library. Download the Win64 package and install it into c:\local\OpenSSL-Win64.

Once asked for Copy OpenSSLs DLLs to select The Windows system directory. That way CMake/Visual Studio will automatically detect them for builds and packaging.

Note

We cannot use the chocolatey package as this one does not provide any development headers.

Choose 1.1.1 LTS from manual downloads for best compatibility.

Boost

Icinga needs the development header and library files from the Boost library.

Visual Studio translates into the following compiler versions:

• msvc-14.2 = Visual Studio 2019

Pre-built Binaries

Prefer the pre-built package over self-compiling, if the newest version already exists.

Download the boost-binaries for

• msvc-14.2 is Visual Studio 2019
• 64 for 64 bit builds

https://sourceforge.net/projects/boost/files/boost-binaries/1.71.0/boost_1_71_0-msvc-14.2-64.exe/download

Run the installer and leave the default installation path in C:\local\boost_1_71_0.

Source & Compile

In order to use the boost development header and library files you need to download Boost and then extract it to e.g. C:\local\boost_1_71_0.

Note

Just use C:\local, the zip file already contains the sub folder. Extraction takes a while, the archive contains more than 70k files.

In order to integrate Boost into Visual Studio, open the Developer Command Prompt from the start menu, and navigate to C:\local\boost_1_71_0.

Execute bootstrap.bat first.

cd C:\local\boost_1_71_0
bootstrap.bat

Once finished, specify the required toolset to compile boost against Visual Studio. This takes quite some time in a Windows VM. Boost Context uses Assembler code, which isn’t treated as exception safe by the VS compiler. Therefore set the additional compilation flag according to this entry.

b2 --toolset=msvc-14.2 link=static threading=multi runtime-link=static address-model=64 asmflags=\safeseh

TortoiseGit

TortoiseGit provides a graphical integration into the Windows explorer. This makes it easier to checkout, commit and whatnot.

Download TortoiseGit on your system.

In order to clone via Git SSH you also need to create a new directory called .ssh inside your user’s home directory. Therefore open a command prompt (win key, type cmd, enter) and run mkdir .ssh. Add your id_rsa private key and id_rsa.pub public key files into that directory.

Start the setup routine and choose OpenSSH as default secure transport when asked.

Open a Windows Explorer window and navigate into

cd %HOMEPATH%\source\repos

Right click and select Git Clone from the context menu.

Use ssh://git@github.com/icinga/icinga2.git for SSH clones, https://github.com/icinga/icinga2.git otherwise.

Packages

CMake uses CPack and NSIS to create the setup executable including all binaries and libraries in addition to setup dialogues and configuration. Therefore we’ll need to install NSIS first.

We also need to install the Windows Installer XML (WIX) toolset. This has .NET 3.5 as a dependency which might need a reboot of the system which is not handled properly by Chocolatey. Therefore install it first and reboot when asked.

Enable-WindowsOptionalFeature -FeatureName "NetFx3" -Online
choco install -y wixtoolset

CMake

Icinga 2 uses CMake to manage the build environment. You can generate the Visual Studio project files using CMake. Download and install CMake. Select to add it to PATH for all users when asked.

Note

In order to properly detect the Boost libraries and VS 2019, install CMake 3.15.2+.

Tip

Cheatsheet: https://www.brianlheim.com/2018/04/09/cmake-cheat-sheet.html

Once setup is completed, open a command prompt and navigate to

cd %HOMEPATH%\source\repos

Build Icinga with specific CMake variables. This generates a new Visual Studio project file called icinga2.sln.

Visual Studio translates into the following:

• msvc-14.2 = Visual Studio 2019

You need to specify the previously installed component paths.

Variable	Value	Description
BOOST_ROOT	C:\local\boost_1_71_0	Root path where you’ve extracted and compiled Boost.
BOOST_LIBRARYDIR	Binary: C:\local\boost_1_71_0\lib64-msvc-14.2, Source: C:\local\boost_1_71_0\stage	Path to the static compiled Boost libraries, directory must contain lib.
BISON_EXECUTABLE	C:\ProgramData\chocolatey\lib\winflexbison\tools\win_bison.exe	Path to the Bison executable.
FLEX_EXECUTABLE	C:\ProgramData\chocolatey\lib\winflexbison\tools\win_flex.exe	Path to the Flex executable.
ICINGA2_WITH_MYSQL	OFF	Requires extra setup for MySQL if set to ON. Not supported for client setups.
ICINGA2_WITH_PGSQL	OFF	Requires extra setup for PgSQL if set to ON. Not supported for client setups.
ICINGA2_UNITY_BUILD	OFF	Disable unity builds for development environments.

Tip: If you have previously opened a terminal, run refreshenv to re-read updated PATH variables.

Build Scripts

Icinga provides the build scripts inside the Git repository.

Open a new Powershell and navigate into the cloned Git repository. Set specific environment variables and run the build scripts.

cd %HOMEPATH%\source\repos\icinga2

.\tools\win32\configure-dev.ps1
.\tools\win32\build.ps1
.\tools\win32\test.ps1

The debug MSI package is located in the debug directory.

If you did not follow the above steps with Boost binaries and OpenSSL paths, you can still modify the environment variables.

$env:CMAKE_GENERATOR='Visual Studio 16 2019'
$env:CMAKE_GENERATOR_PLATFORM='x64'

$env:ICINGA2_INSTALLPATH = 'C:\Program Files\Icinga2-debug'
$env:ICINGA2_BUILDPATH='debug'
$env:CMAKE_BUILD_TYPE='Debug'
$env:OPENSSL_ROOT_DIR='C:\OpenSSL-Win64'
$env:BOOST_ROOT='C:\local\boost_1_71_0'
$env:BOOST_LIBRARYDIR='C:\local\boost_1_71_0\lib64-msvc-14.2'

Icinga 2 in Visual Studio

This requires running the configure script once.

Navigate to

cd %HOMEPATH%\source\repos\icinga2\debug

Open icinga2.sln. Log into Visual Studio when asked.

On the right panel, select to build the Bin/icinga-app solution.

The executable binaries are located in Bin\Release\Debug in your icinga2 project directory.

Navigate there and run icinga2.exe --version.

cd %HOMEPATH%\source\repos\icinga2\Bin\Release\Debug
icinga2.exe --version

Release Package

This is part of the build process script. Override the build type and pick a different build directory.

cd %HOMEPATH%\source\repos\icinga2

$env:ICINGA2_BUILDPATH='release'
$env:CMAKE_BUILD_TYPE='RelWithDebInfo'

.\tools\win32\configure-dev.ps1
.\tools\win32\build.ps1
.\tools\win32\test.ps1

The release MSI package is located in the release directory.

Embedded Dev Env: Pi

Note

This isn’t officially supported yet, just a few hints how you can do it yourself.

The following examples source from armhf on Raspberry Pi.

ccache

apt install -y ccache

/usr/sbin/update-ccache-symlinks

echo 'export PATH="/usr/lib/ccache:$PATH"' | tee -a ~/.bashrc

source ~/.bashrc && echo $PATH

Build

Copy the icinga2 source code into $HOME/icinga2. Clone the deb-icinga2 repository into debian/.

git clone https://github.com/Icinga/icinga2 $HOME/icinga2
git clone https://github.com/Icinga/deb-icinga2 $HOME/icinga2/debian

Then build a Debian package and install it like normal.

dpkg-buildpackage -uc -us
