Izvo zvinoshandiswa zvinokutendera kuti uwiriranise zviri mukati medhairekitori remunharaunda nedhairekitori remudziyo unomhanya musumbu. Chishandiso chakadaro chakanakira vanogadzira scripting programming mitauro, vane dambudziko guru kuendesa kodhi kumudziyo unomhanya. Ksync yakagadzirirwa kudzikisa musoro uyu.

Kana yatangwa kamwe chete nemurairo ksync init a DaemonSet inogadzirwa musumbu, iyo inoshandiswa kutarisa mamiriro efaira system yemudziyo wakasarudzwa. Pakombuta yake yemuno, mugadziri anomhanyisa kuraira ksync watch, iyo inotarisa zvigadziriso uye inomhanya sync, iyo inowiriranisa mafaera zvakananga nesumbu.

Chasara kudzidzisa ksync yekubatanidza nei. Semuenzaniso, murairo uyu:

ksync create --name=myproject --namespace=test --selector=app=backend --container=php --reload=false /home/user/myproject/ /var/www/myproject/

... achagadzira murindi ane zita myprojectiyo ichatsvaga podhi ine label app=backend uye edza kuwiriranisa dhairekitori renzvimbo /home/user/myproject/ nekatalogi /var/www/myproject/ pamudziyo wakanzi php.

Matambudziko uye manotsi pane ksync kubva pane zvakaitika kwatiri:

Inofanirwa kushandiswa paKubernetes cluster node overlay2 semutyairi wekuchengetedza weDocker. Iyo yekushandisa haishande nemamwe chero.
Paunenge uchishandisa Windows semutengi OS, iyo faira system inoona inogona kusashanda nemazvo. Iyi bug yakaonekwa pakushanda nemadhairekitori akakura - aine nhamba huru yemafaera nemadhairekitori. Isu takagadzira nyaya yakakodzera muchirongwa chesyncthing, asi hapana kufambira mberi pachiri (kubvira kutanga kwaChikunguru).
Shandisa faira .stignore kudoma makwara kana mapatani emafaira asingade kuwiriraniswa (semuenzaniso, madhairekitori app/cache и .git).
Nekutadza, ksync inozotangazve mudziyo pese mafaera achinja. KuNode.js izvi zviri nyore, asi zvePHP hazvina kufanira zvachose. Zviri nani kudzima opcache uye kushandisa mureza --reload=false.
Iyo configuration inogona nguva dzose kugadziriswa mukati $HOME/.ksync/ksync.yaml.

Mhinduro kubva kukambani yezita rimwe chete, iyo inopa masumbu akagadziriswa neKubernetes yekuvandudza kwechikwata. Izvo zvinoshandiswa zvakagadzirirwa zvikwata zvekutengesa, asi zvinoshanda zvakanaka nemamwe chero.

Paunenge uchimhanya murairo devspace init mune iyo catalog yeprojekiti iwe uchapihwa (inopindirana):

sarudza inoshanda Kubernetes cluster,
shandisa iripo Dockerfile (kana kugadzira imwe nyowani) kugadzira mudziyo wakavakirwa pairi,
sarudza nzvimbo yekuchengetera mifananidzo yemidziyo, nezvimwe.

Mushure mese aya matanho ekugadzirira, unogona kutanga kusimudzira nekumhanyisa kuraira devspace dev. Iyo inovaka mudziyo, woiisa kune repository, buritsa iyo yekuendesa kune iyo cluster uye wotanga kutumira chiteshi uye kuwiriranisa kwemudziyo nedhairekitori renzvimbo.

Sarudzo, iwe unozokurudzirwa kufambisa iyo terminal kune mugaba. Iwe haufanirwe kuramba, nekuti muchokwadi mudziyo unotanga nekuraira kwekurara, uye yekuyedza chaiyo application inoda kutangwa nemaoko.

Pakupedzisira, chikwata devspace deploy inoburitsa iyo application uye yakabatana zvivakwa kune cluster, mushure mezvo zvese zvinotanga kushanda mukurwisa mode.

Yese magadzirirwo eprojekiti anochengetwa mufaira devspace.yaml. Pamusoro pemagadzirirwo enzvimbo yekusimudzira, iwe unogona zvakare kuwana tsananguro yezvivakwa mairi, zvakafanana neyakajairwa Kubernetes inoratidzira, inongorerutswa zvakanyanya.

Architecture uye nhanho huru dzekushanda neDevSpace

Mukuwedzera, zviri nyore kuwedzera chikamu chakafanotaurwa (semuenzaniso, MySQL DBMS) kana Helm chati kupurojekiti. Verenga zvakawanda mu zvinyorwa - hazvina kuoma.

Skaffold

Website; GitHub.
Pfupi GH nhamba: 7423 nyeredzi, 4173 inoita, 136 vabatsiri.
Mutauro: Enda.
Rezinesi: Apache License 2.0.

Ichi chishandiso kubva kuGoogle chinoti chinovhara zvese zvinodiwa nemugadziri ane kodhi neimwe nzira inomhanya pane Kubernetes cluster. Kutanga kuishandisa hazvisi nyore se devspace: hapana kupindirana, kuona mutauro uye kugadzira otomatiki Dockerfile havangakupi pano.

Nekudaro, kana izvi zvikasakutyisa, hezvino izvo Skaffold inobvumidza iwe kuti uite:

Tevera shanduko yekodhi kodhi.
Iwiriranise nemudziyo wepodhi kana isingade kuungana.
Unganidza midziyo ine kodhi, kana mutauro uchidudzirwa, kana unganidza zvigadzirwa wozvirongedza mumidziyo.
Mapikicha anenge abuda anotariswa otomatiki pachishandiswa mudziyo-chimiro-bvunzo.
Kumaka uye kurodha mifananidzo kuDocker Registry.
Tumira application muchikwata uchishandisa kubectl, Helm kana kustomize.
Ita port forwarding.
Debug application yakanyorwa muJava, Node.js, Python.

Kufambiswa kwebasa mumhando dzakasiyana-siyana kunotsanangurwa zvinotsanangurwa mufaira skaffold.yaml. Kune purojekiti, iwe unogona zvakare kutsanangura akati wandei maprofiles maunogona kuchinja zvishoma kana zvachose gungano uye danho rekutumira. Semuenzaniso, yekusimudzira, tsanangura mufananidzo wakanakira mugadziri, uye wekuita uye kugadzira - ishoma (+ shandisa securityContext midziyo kana kutsanangura zvakare cluster umo iyo application ichashandiswa).

Docker midziyo inogona kuvakwa munharaunda kana kure: mukati Google Cloud Build kana musumbu uchishandisa Kaniko. Bazel naJib Maven/Gradle vanotsigirwawo. Nekumaka, Skaffold inotsigira akawanda mazano: ne git commit hash, zuva / nguva, sha256-sum yezvinyorwa, nezvimwe.

Kusiyana, zvakakosha kucherechedza mukana wekuyedza midziyo. Iyo yakatotaurwa yemudziyo-chimiro-yekuyedza chimiro chinopa dzinotevera nzira dzekusimbisa:

Kuita mirairo mukati memudziyo une mastatus ekutevera ekubuda uye kutarisa mameseji ekubuda kwemurairo.
Kutarisa kuvepo kwemafaira mumudziyo uye nekufananidza hunhu hwakatsanangurwa.
Kudzora zvemukati zvemafaira uchishandisa zvinogara zvichitaurwa.
Kuongororwa kwemetadata yemufananidzo (ENV, ENTRYPOINT, VOLUMES zvichingoenda zvakadaro.).
Kutarisa rezinesi kuenderana.

Kuwiriranisa mafaera nemudziyo hakuitwe nenzira yakanyanya kunaka: Skaffold inongogadzira archive ine masosi, inokopa uye nekuiburitsa mumudziyo (tara inofanirwa kuiswa). Naizvozvo, kana basa rako guru riri rekubatanidza kodhi, zviri nani kutarisa kune yakasarudzika mhinduro (ksync).

Matanho makuru eSkaffold oparesheni

Kazhinji, chishandiso hachikubvumidze kuti utore kubva Kubernetes inoratidzira uye haina chero yekudyidzana, saka zvingaite seyakaoma kugona. Asi izvi zvakare zvakanakira - rusununguko rukuru rwekuita.

Garden

Website; GitHub.
Pfupi GH nhamba: 1063 nyeredzi, 1927 anoita, 17 vabatsiri.
Mutauro: TypeScript (yakarongwa kupatsanura purojekiti muzvikamu zvakati wandei, zvimwe zvacho zvichange zviri muGo, uye zvakare kugadzira SDK yekugadzira ma-add-ons muTypeScript/JavaScript uye Go).
Rezinesi: Apache License 2.0.

SaSkaffold, Gadheni rinovavarira kuita otomatiki maitiro ekuendesa kodhi yekushandisa kune K8s cluster. Kuti uite izvi, iwe unofanirwa kutanga watsanangura chimiro chepurojekiti muYAML faira, wobva wamhanyisa rairo garden dev. Achaita mashiripiti ese:

Unganidza midziyo ine zvikamu zvakasiyana-siyana zvepurojekiti.
Inoita yekubatanidza uye bvunzo dzeyuniti, kana paine dzakatsanangurwa.
Inoburitsa zvese zvikamu zveprojekiti kune cluster.
Kana iyo kodhi kodhi ikachinja, ichatangazve pombi yese.

Chinangwa chikuru chekushandisa chishandiso ichi kugovera sumbu riri kure nechikwata chekusimudzira. Muchiitiko ichi, kana zvimwe zvekuvaka uye nhanho dzekuedza dzakatoitwa, izvi zvichanyanya kukurumidzira hurongwa hwese, sezvo Bindu richakwanisa kushandisa cached mhinduro.

A purojekiti module inogona kunge iri mudziyo, Maven mudziyo, Helm chati, manifest ye kubectl apply kana kunyange OpenFaaS basa. Uyezve, chero yemamodule anogona kudhonzwa kubva kure Git repository. Module inogona kana kusatsanangura masevhisi, mabasa, uye bvunzo. Masevhisi uye mabasa anogona kuve nekutsamira, saka iwe unogona kuona kutevedzana kwekutumira kweimwe sevhisi uye kuronga kutangwa kwemabasa uye bvunzo.

Bindu rinopa mushandisi dhibhodhi rakanaka (ikozvino mukati experimental state), iyo inoratidza girafu yeprojekiti: zvikamu, kutevedzana kwegungano, kuitwa kwemabasa uye bvunzo, kubatana kwavo uye zvinoenderana. Imo mubrowser, unogona kuona matanda ezvese mapurojekiti epurojekiti uye tarisa izvo chimwe chikamu chinobuda kuburikidza neHTTP (kana, chokwadi, ingress resource yakaziviswa iyo).

Panel for Garden

Ichi chishandiso zvakare chine inopisa-reload modhi, iyo inongo wiriranisa script shanduko nemudziyo uri musumbu, ichimhanyisa zvakanyanya maitiro ekugadzirisa application. Garden ine yakanaka zvinyorwa uye kwete zvakaipa seti yemienzaniso, zvichikutendera kuti ukurumidze kujaira uye wotanga kuishandisa. Nenzira, munguva pfupi yapfuura takaburitsa chinyorwa chekushandura kubva kuvanyori varo.
