Docker waa tiknoolajiyo beddeshay sida software-ka loo dhiso, loo tijaabiyo, loona deploy gareeyo. Haddii hore lagu tiirsanaa virtual machines (VMs) oo culus, Docker wuxuu keenay fikradda containers —goob uu barnaamijkaagu si gooni ah ugu run gareesmi karo. isagoo wata dhammaan files, libraries, iyo configurations uu u baahan yahay.

Farqiga ugu weyn waa miisaan iyo xawaare. Virtual machine waxay qaadataa daqiiqado si ay u shiddo sababtoo ah waxay u baahan tahay nidaam buuxa (OS), halka Docker container uu ku run gareeyo daqiiqad gudaheed maadaama uu la wadaago kernel-ka nidaamka hoose.

Docker wuxuu leeyahay saddex fikradood oo muhiim ah:

Image: waa barnaamijkaaga — tusaale ahaan "Python app" ama "Node.js service".

Container: waa halka image-kaas ku run garoobo.

Dockerfile: waa fayl lagu qeexayo sida image-ka loo dhisayo, tillaabo kasta oo code-kaaga loo diyaarinayo.

Bal qiyaas makhaayad. Container waa sanduuq yar oo cunto gaar ah lagu diyaariyo: mid bariis ah, mid baasto ah, mid cambuulo ah. Sanduuq kasta waa mid madax-bannaan — haddii mid xumaado, kuwa kale ma saameeyo. Docker wuxuu nidaamkaa keenay dunida development-ga: barnaamij kasta sanduuqiisa ayuu leeyahay, qalad mid ku dhaco kan kale ma burburinayo.

Docker waa sanduuqa amniga ee software-ka. Waa meesha code-kaagu si nadiif ah ugu shaqeyn karo, meel kasta oo la geeyo. Qof kasta oo developer ah waa inuu bartaa Docker — maxaa yeelay software deployment-ka waxaa lagu cabiraa hal eray: Containerization.
