Einsatz von Git im Unternehmen

5,154 views

Published on

Immer mehr Open-Source-Projekte benutzen Git. Der Vorteil ist klar: Viele Entwickler arbeiten weltweit verteilt, zeitlich versetzt und nur lose gesteuert an einem Projekt. Das passt hervorragend zum dezentralen Ansatz von Git. Git untersützt die benötigten Workflows für eine solche Projektorganisation hervorragend - denn dafür wurde es entwickelt.

Der Vortrag diskutiert die Fragen, die sich bei der Einführung von Git im eigenen Unternehmen stellen:
- Welche Vorteile bringt Git für In-House-Projekte und Produktentwicklungen?
- Wie geht man vor, wenn man Git einführen möchte?
- Mit welchen Problemen ist beim Umstieg zu rechnen?
- Sind die gleichen Workflows, die in der Open-Source-Welt funktionieren auch für die Unternehmenswelt sinnvoll?

Am Beginn des Vortrages gibt es einem kurzen Einstieg in Git, so dass auch Git-Unerfahrene eine Idee von den Fähigkeiten einer dezentralen Versionsverwaltung erhalten.

  9. 9. Dezentrales Arbeiten * aus „Workflows mit Git“ 9
  10. 10. Dezentrale Versionsnummern Es gibt keinen zentralen Server der die Versionen nummerieren kann Für alle Inhalte werden Hash-Werte als Schlüssel berechnet (SHA, 160 Bit) Commit-Hash - Dezentrale Version des gesamten Projektes Git versioniert immer das ganze Projekt * aus „Workflows mit Git“ 10

Git für EntwicklerMöglichkeiten Flexible lokale Arbeitsweisen Kleine Commits, Lokale Branches Performante lokale Operationen Gute Unterstützung von Merging Gute Recherche-Möglichkeiten in der Historie Bisection - Unterstützung bei der Fehlersuche Offline arbeiten ist möglich Git kann parallel zur zentralen Versionierung genutzt werden 17
  18. 18. Entwickler - Trade-OffsTrade-Offs Starke Kommandozeilen-Orientierung Komplexität führt zu steilerer Lernkurve Lokale Administration notwendig Komplexere Workflows z.B.

  19. 19.

  23. 23. Administration - Trade-OffsTrade-Offs Keine feingranulare Rechteverwaltung möglich Für große Binaries nur bedingt geeignet Historien sind änderbar Entscheidung welche Repositorys gesichert werden müssen Tools sind sehr an Unix-Infrastruktur ausgerichtetMaßnahmen Workflows für mehr Kontrolle definieren Definition von Staging-Pipelines „Network of Trust“ Einsatz von Server-Werkzeugen für mehr Kontrolle z.B. Gitolite oder Gerrit Auslagerung an Dienstleister evaluieren z.B. GitHub 23

  25. 25. QualitätssicherungMöglichkeiten Feste Versionsstände durch Hashes Feature-Branches erleichtern die Zuordnung von Änderungen zu Features Genauere Recherche-Möglichkeiten sind möglich Kontrollierter Umgang mit Bugfixes ist möglich, z.B. Cherry-Picking Versionierte Zusatzinformationen sind möglich Nachträgliche Änderungen in Installationen werden nachvollziehbar Kundenversion kann Hash enthalten 25
  26. 26. Qualitätssicherung - Trade-OffsTrade-Offs Know-How in Git notwendig Integration von Git in Issue-TrackingMaßnahmen Git-Einführung bewusst planen Schulung, Bücher Recherche-Möglichkeiten erlernen Definition von Workflows QA-Tools überprüfen 26
  27. 27. Grenzen von GitHohe Komplexität Dezentraler Ansatz Fokus auf Kommandozeile Viele Befehle mit sehr vielen Parametern Befehle sind sehr technisch orientiert und nicht immer selbsterklärendWorkflows sind nicht standardisiertKomplizierter Umgang mit SubmodulenHoher Ressourcenverbrauch bei großen binärenDateienRepositorys können nur vollständig verwendetwerdenAutorisierung nur auf dem ganzen Repository 27
  28. 28. Migration (I)1. Git lernen - Erfahrungen sammeln a. Isoliert arbeiten, Parallel arbeiten2. Entscheidungen treffen a. Alle Projekte auf einmal migrieren? b. Welche Projekte migrieren? c. Bestehende Struktur übernehmen? d. Unterbrechung der Entwicklung möglich? e. Branching-Strategie / Workflows festlegen f. Werkzeuge auswählen3. Neues Repository erzeugen a. Branches finden b. Repository einrichten c. Inhalte übernehmen d. Ergebnisse überprüfen 28
  29. 29. Migration(II)4. Repository in Betrieb nehmen a. Ankündigung / Notfallplan während Umstellung b. Schulung der Entwickler c. Letzte Änderungen aus alter Versionierung nachziehen d. Neues Repository bereitstellen, Entwickler informieren e. Null-Release durchführen f. Altes Repository auf Read-Only setzen g. Entwickler unterstützen5. Aufräumen des Git-Repository a. Temporäre Branches löschen 29
