Ho ngotsoe lingoliloeng tse ngata mabapi le mokhoa oa ho ngola Dockerfile ka nepo. Empa ha kea fumana litaelo tsa ho ngola li-Dockerfiles tse fosahetseng. Ke tlatsa sekheo sena. Mme mohlomong mererong eo ke e fumanang tšehetso, ho tla ba le li-dockerfiles tse joalo tse fokolang.

Litlhaku tsohle, maemo le Dockerfile ke mashano. Haeba u itseba, masoabi.

Ho theha Dockerfile, e tšosang ebile e tšabeha

Peter (Moqapi ea phahameng oa java/rubby/php): Mosebetsi-'moho le Vasily, na u se u kentse mojule o mocha ho Docker?

Batho ba tla re "Kea leboha" ho uena.
O tla thusa batho
