Icinga for Windows: How to enable features during unattended automated install?

Icinga 2
1

I am attempting to use Icinga for Windows + Icinga Driector self service API to deploy and register our agents on Windows endpoints in a single command.

After a lot of playing in the Icinga Powershell Framework module, I was able to find almost the complete set of values to pass to the InstallCommand argument, except for how to enable the Checker feature during install.

After installation, I’m finding that I need to manually enable this feature via cli call and restart the agent to get checks to work. But I am trying to achieve as much of an automated/unattended installation as possible. Does anybody know what value to pass to enable this feature during installation?

Here is my code:

[Net.ServicePointManager]::SecurityProtocol = 'tls12, tls11';
$ProgressPreference                         = 'SilentlyContinue';
[string]$ScriptFile                         = 'C:\Windows\Temp\IcingaForWindows.ps1';

Invoke-WebRequest `
    -UseBasicParsing `
    -Uri 'https://packages.icinga.com/IcingaForWindows/IcingaForWindows.ps1' `
    -OutFile $ScriptFile;

& $ScriptFile `
    -AllowUpdate `
    -ModuleDirectory 'C:\Program Files\WindowsPowerShell\Modules' `
    -InstallCommand '{"IfW-AgentDirectory":{"Values":["C:\\Program Files\\ICINGA2"]},"IfW-AgentUser":{"Values":["NT Authority\\NetworkService"]},"IfW-AgentVersion":{"Values":["release"]},"IfW-CAServer":{"Values":["<icinga_master>"]},"IfW-DirectorSelfServiceKey":{"Values":["<director_selfservice_key>"]},"IfW-DirectorUrl":{"Values":["https://<icinga_host>/icingaweb2/director"]},"IfW-ForceCertificateCreation":{"Selection":"0"},"IfW-GlobalZones":{"Selection":"0"},"IfW-Hostname":{"Selection":"1"},"IfW-InstallAgent":{"Selection":"0"},"IfW-InstallApiChecks":{"Selection":"1"},"IfW-InstallJEAProfile":{"Selection":"2"},"IfW-InstallPlugins":{"Selection":"0"},"IfW-InstallService":{"Selection":"0"},"IfW-ParentAddress":{"Values":{"<icinga_master>":<icinga_master>"]}},"IfW-ParentNodes":{"Values":["<icinga_master>"]},"IfW-ParentZone":{"Values":["<icinga_master>"]},"IfW-Port":{"Values":[5665]},"IfW-ServiceRecovery":{"Selection":"1"},"IfW-StableRepository":{"Values":["https://packages.icinga.com/IcingaForWindows/stable/ifw.repo.json"]},"IfW-WindowsFirewall":{"Selection":"0"},"IfW-WindowsServiceDirectory":{"Values":["C:\\Program Files\\icinga-framework-service"]}}'

Are all of the various InstallCommand values documented anywhere? Thanks in advance.

They don’t appear to be documented anywhere but grepping the icinga-powershell-framework repo for Set-Alias -Name 'IfW- gives the following:

$ grep -r "Set-Alias -Name 'IfW-" |awk '{ gsub(/\'/, "", $3); print $3 }' |sort |uniq

The values of (some of) these attributes are stored in the Powershell configuration:

PS C:\Users\Administrator>  $config = Get-Content `
        -Path (Join-Path `
            -Path (Get-IcingaPowerShellConfigDir) -ChildPath "config.json" `
    ) | ConvertFrom-Json;

For example, I managed to set a custom hostname when registering a host with the Director self-service API like so:

$InstallCommand = @{
    'IfW-DirectorUrl' = @{
        'Values' = ('https://icinga.example.com/icingaweb2/director');
    };
    'IfW-DirectorSelfServiceKey' = @{
        'Values' = ('xxxx');
    };
    'IfW-Hostname' = @{
        'Selection' = "6";
    };
    'IfW-CustomHostname' = @{
        'Values' = ('windows.example.com');
    };
}

Install-Icinga `
    -InstallCommand (ConvertTo-Json -InputObject $InstallCommand);

Note that I had to set the Selection property of the IfW-Hostname attribute to 6, which allows you to set a custom hostname:

6 is the index of the relevant entry (starting from 0) in the argument to -Entries.
