Mokhoa oa ho bokella merero ho Jenkins haeba o hloka libaka tse ngata tse fapaneng

Mokhoa oa ho bokella merero ho Jenkins haeba o hloka libaka tse ngata tse fapaneng

Ho na le lingoliloeng tse ngata ka Habré mabapi le Jenkins, empa ke tse fokolang tse hlalosang mehlala ea kamoo Jenkins le baemeli ba li-docker ba sebetsang kateng. Lisebelisoa tsohle tse tsebahalang tsa ho aha merero joalo ka Drone.io, Pipeline ea Bitbucket, GitLab, Liketso tsa GitHub le ba bang, ba ka bokella tsohle ka lijaneng. Empa ho thoe'ng ka Jenkins?

Kajeno ho na le tharollo ea bothata: Jenkins 2 o sebetsa hantle le eena Baemeli ba Docker. Sehloohong sena ke batla ho arolelana phihlelo ea ka le ho bontša kamoo u ka e etsang u le mong.

Ke hobane'ng ha ke ile ka qala ho rarolla bothata boo?

Kaha re kopane Citronium Hobane re sebelisa mekhoa e mengata e fapaneng ea theknoloji, re tlameha ho boloka mefuta e fapaneng ea Node.JS, Gradle, Ruby, JDK le tse ling mochine oa kopano. Empa hangata likhohlano tsa liphetolelo li ke ke tsa qojoa. E, u tla be u nepile ha u re ho na le batsamaisi ba mefuta e fapaneng ba joalo ka nvm, rvm, empa ha se ntho e 'ngoe le e' ngoe e tsamaeang hantle le bona mme litharollo tsena li na le mathata:

  • palo e kholo ea nako ea ho sebetsa eo bahlahisi ba lebalang ho e hloekisa;
  • ho na le likhohlano lipakeng tsa mefuta e fapaneng ea nako ea ho matha e tšoanang;
  • Moetsi e mong le e mong o hloka sete e fapaneng ea likarolo.

Ho na le mathata a mang, empa e re ke u bolelle ka tharollo.

Jenkins sebakeng sa Docker

Kaha Docker e se e thehiloe hantle lefats'eng la nts'etsopele, hoo e ka bang eng kapa eng e ka tsamaisoang ho sebelisoa Docker. Tharollo ea ka ke ho ba le Jenkins ho Docker le ho khona ho tsamaisa lijana tse ling tsa Docker. Potso ena e qalile ho botsoa morao ka 2013 sehloohong se reng "Hona joale Docker e ka sebetsa ka har'a Docker".

Ka bokhutšoanyane, o hloka feela ho kenya Docker ka boeona ka sejaneng se sebetsang ebe o kenya faele /var/run/docker.sock.

Mona ke mohlala oa Dockerfile o ileng oa fetohela Jenkins.

Kahoo, re na le setshelo sa Docker se ka phethisang litaelo tsa Docker mochining oa moamoheli.

Hase khale Jenkins o ile a fumana monyetla oa ho hlalosa melao ea eona a sebelisa Pipe syntax, e etsang hore ho be bonolo haholo ho fetola script ea ho aha le ho e boloka sebakeng sa polokelo.

Re hlalositse tikoloho ea kopano, empa Jenkins o amana joang le eona? 'Me baemeli ba Jenkins ba ka sebetsa le litšoantšo tse joalo tsa Docker' me ba li hahe ka hare.
