• zašto ne appwiz.cpl (Add or Remove Programs) ?
• OneGet, Powershell Gallery
• ... ili ms-windows-store:

• apt-get (Debian based systems)
• yum/dnf (Red Hat & friends)
• homebrew (OS X)
• pacman Arch, portage Gentoo, pkg Solaris ....

Treba mi Firefox: `choco install firefox`

ili stariji: `cinst firefox -version 46.0.1`

Update firefox: `cup firefox`

Meh: `choco uninstall firefox`

Teba mi PowerShell: cinst powershell
(instalira dotnet ako je potrebno)

Želim sve browsere: `cinst allbrowsers`

Teba mi mnogo toga: `cinst allbrowsers skype powershell 7zip git`

Outdated: `choco outdated`

Update svega: `cup all`

Personalni sistem

• Manualno kod svakog OS install
• Kloniranje nije preterano zanimljivo
• Portabilne aplikacije ne mogu lako da se update-uju
• Problem mnogo uređaja

Tim

• Podrazumeva se ili postoji dokumentovano
• Nekad se neko usudi da uradi silent install
  naporno, 20+ formata
• Da li random osoba ume (sitni detalji)
• Da li smo svesni tekućeg stanja sistema
• Dinamika tima kod višegodišnjih projekata
• Group policy - previše generalizovan

Produkcija

• Manuelna okruženja.
• Reimplementacija na build serveru.
• Imutabilna infrastruktura

- jedan interfejs - *mnogo* pakovanja i **up to date** - stabilnost i reproduktivnost - da bude sigurno - i decentralizovano - lako za korišćenje (KISS) i ekstenzibilno

Fakti

- maintainers: 1100 - install svake sekunde - [community repo](https://chocolatey.org/packages) - moderacija - trusted people/pkgs - virus total (50+ AV) - XP .. Windows 10

• FOS NuGet kao format pakovanja
  • decentralizovan
  • specifikacija dependency-ja
  • nema security
• Fensi zip fajlovi koji imaju pristup PowerShell-u.
• Dodatna logika koja fali u instalerima.
• CLI i GUI tool , ali ipak CLI, stvarno
ALI NE CMD.EXE

Problemi

- Custom installeri koji nemaju silent opcije - Autohotkey - Registry problemi - Nekad je teško napraviti downloader - Mrežni problemi - Ogromni installer-i - Rejected

- Nano image je nekoliko stotina MB - Nano zahteva PowerShell: `NanoServerImageGenerator.psd1` - Nano ne koristi MSI subsistem već WSA - Chocolatey će podržati WSA i MSI na nano serveru - ETA: 6 meseci
