När du distribuerar programuppdateringar är det viktigt att den teknik du använder för att leverera uppdateringen gör följande:
- Aktivera initiering.
- Distribuera uppdateringen.
- Dirigera trafik till den uppdaterade versionen.
- Testa den uppdaterade versionen efter routning av trafik.
- I händelse av fel kör du steg för att återställa till den senast kända bra versionen.
Vi uppnår detta genom att använda livscykelkrokar som kan köra steg under distributionen. Var och en av livscykelkrokerna matchas till ett agentjobb eller ett serverjobb (eller ett container- eller valideringsjobb i framtiden), beroende på poolattributet. Som standard ärver livscykelkrokerna den pool som anges av distributionsjobbet.
Distributionsjobb använder $(Pipeline.Workspace) system variable.
Om du använder lokalt installerade agenter kan du använda alternativen för att rensa arbetsytan för arbetsytan för att rensa distributionsarbetsytan.

strategi: runOnce
Distributionsstrategin runOnce distribuerar ändringar genom att köra vart och ett av stegen en gång.

runOnce är den enklaste distributionsstrategin där alla livscykelkrokar, nämligen preDeploydeploy, routeTrafficoch postRouteTraffic, körs en gång. Sedan körs antingen on: success eller on: failure .
strategi: rullande
En löpande distribution ersätter instanser av den tidigare versionen av ett program med instanser av den nya versionen av programmet på en fast uppsättning virtuella datorer (rullande uppsättning) i varje iteration.
strategy:
rolling: # Rolling Deployment strategy.
maxParallel: string # Maximum number of jobs running in parallel.
preDeploy: # Pre deploy hook for rolling deployment strategy.
steps: [ task | script | powershell | pwsh | bash | checkout | download | downloadBuild | getPackage | publish | template | reviewApp ] # A list of steps to run.
pool: string | pool # Pool where pre deploy steps will run.

Strategi för canary-distribution är en avancerad distributionsstrategi som hjälper till att minska risken med att lansera nya versioner av program. Genom att använda den här strategin kan du distribuera ändringarna till en liten delmängd servrar först. När du får mer förtroende för den nya versionen kan du släppa den till fler servrar i infrastrukturen och dirigera mer trafik till den.
