Gore nehafu rapfuura, munaKurume 5, 2018, Google yakaburitsa yekutanga alpha vhezheni yayo Open Source purojekiti yeCI/CD inonzi. , avo vavariro yavo yaive yekugadzira "zvakareruka uye zvinodzokororwa Kubernetes budiriro" kuitira kuti vanogadzira vatarise kusimudzira kwete kutonga. Chii chingave chinonakidza nezveSkaffold? Sezvazvinozoitika, ine mashoma manomano kumusoro kwayo iyo inogona kuiita chishandiso chine simba kumugadziri, uye pamwe kunyangwe injiniya yekushanda. Ngatizivei nezve purojekiti uye kugona kwayo.
NB: Nenzira, takatotaura muchidimbu nezveSkaffold mune yedu general , vane hupenyu hwakabatana neKubernetes.
Dzidziso. Chinangwa uye kugona
Saka, kazhinji kutaura, Skaffold inogadzirisa dambudziko rekuita otomatiki kutenderera kweCI/CD (pakuvaka, kusunda, kuendesa matanho), ichipa mugadziri wemhinduro yekukurumidza, i.e. kugona kukurumidza kugamuchira mhedzisiro yeanotevera kodhi shanduko - muchimiro cheyakagadziridzwa application inomhanya muKubernetes cluster. Uye inogona kushanda mumasekete akasiyana (dev, nhanho, kugadzirwa ...), iyo Skaffold inobatsira kutsanangura mapaipi anoenderana ekuburitsa.
Skaffold's source code yakanyorwa muGo, pasi pemahara Apache License 2.0 (GitHub).
Ngatitarisei mabasa makuru uye maitiro. Yekutanga inosanganisira zvinotevera:
- Skaffold inopa maturusi ekugadzira CI/CD mapaipi.
- Inokutendera kuti utarise shanduko mune kodhi kodhi kumashure uye kumhanya otomatiki maitiro ekuunganidza kodhi mumidziyo mifananidzo, kuburitsa iyi mifananidzo muDocker Registry uye nekuiendesa kune Kubernetes cluster.
- Inowiriranisa mafaera mudura nedhairekitori rekushanda mumudziyo.
- Edza otomatiki uchishandisa mudziyo-chimiro-bvunzo.
- Forwards ports.
- Inoverenga matanda ekushandisa ari mugaba.
- Inobatsira mukugadzirisa zvikumbiro zvakanyorwa muJava, Node.js, Python, Go.
Zvino nezve maficha:
- Skaffold pachayo haina cluster-side components. Ndiko kuti, hapana chikonzero chekuwedzera kugadzirisa Kubernetes kushandisa iyi yekushandisa.
- Mapaipi akasiyana ekushandisa kwako. Iwe unofanirwa kuburitsa kodhi kune yemuno Minikube iwe uchigadzira, uye wozoenda pachinhanho kana kugadzira? Nechinangwa ichi pane uye zvigadziriso zvemushandisi, nharaunda dzakasiyana uye mireza, izvo zvinokutendera iwe kutsanangura mapaipi akasiyana kune imwe application.
- CLI. Chete console utility uye zvigadziriso muYAML. PaInternet unogona kuwana mareferensi ekuedza kugadzira , zvisinei, panguva ino izvi zvingangoreva chete kuti mumwe munhu anomuda, asi kwete chaizvoizvo.
- Modularity. Skaffold haisi yekukohwa yakamira yega, asi inovavarira kushandisa mamodule ega kana mhinduro dziripo dzemamwe mabasa.
Mufananidzo wekupedzisira:
- Muchikamu chekutanga unogona kushandisa:
- docker inovaka munharaunda, musumbu uchishandisa kaniko kana muGoogle Cloud Build;
- Bazel locally;
- Jib Maven naJib Gradle munharaunda kana muGoogle Cloud Build;
- tsika kuvaka zvinyorwa zvinomhanya munharaunda. Kana iwe uchida kumhanyisa imwe (inochinjika / yakajairwa /...) kuvaka mhinduro, inotsanangurwa mune script kuitira kuti Skaffold itange iyo () Izvi zvinokubvumira kushandisa chero muunganidzi anogona kunzi uchishandisa script;
- Padanho rekuyedza, izvo zvatotaurwa ;
- Kuti zvitumirwe zvinotevera zvinopihwa:
- Kubectl;
- Helm;
- gadzirisa.
Nekuda kweizvi, Skaffold inogona kunzi yakasarudzika chimiro chekuvaka CI/CD. Heino muenzaniso wekufambisa kana uchiishandisa (kubva pane zvinyorwa zveprojekiti):
Basa raSkaffold rinotaridzika sei mune zvakajairika?
- Iyo yekushandisa monitors inochinja mune source code dhairekitori. Kana magadzirirwo akaitwa kumafaira, anowiriraniswa neiyo application pod muKubernetes cluster. Kana zvichibvira, pasina kubatanidzazve mufananidzo. Zvikasadaro, chifananidzo chitsva chinounganidzwa.
- Mufananidzo wakaunganidzwa unotariswa uchishandisa mudziyo-chimiro-bvunzo, wamaka uye unotumirwa kuDocker Registry.
- Mushure meizvi, chifananidzo chinoiswa - chakaiswa muKubernetes cluster.
- Kana kuvhurwa kwakatangwa uchishandisa murairo
skaffold dev, ipapo tinotanga kugamuchira matanda kubva pachikumbiro, uye Skaffold inomirira shanduko kuti idzokorore zviito zvese zvakare.
Mufananidzo wematanho makuru eSkaffold oparesheni
Dzidzira. Kuedza Skaffold
Kuratidza kushandiswa kweSkaffold, ini ndichatora muenzaniso kubva . Zviya, Iwe unogona kuwana mimwe mienzaniso yakawanda iyo inofunga zvakasiyana zvakasiyana. Ini ndichaita zvese zviito munharaunda muMinikube. Kuisa kuri nyore uye kunotora maminetsi mashoma, uye iwe uchada kubectl kuti utange.
