Malangizo ena amomwe mungafulumizitse kupanga zithunzi za Docker. Mwachitsanzo, mpaka 30 masekondi

Mbali isanapangidwe, m'masiku ano a oimba ovuta ndi CI / CD, pali njira yayitali yopitira pakudzipereka kupita ku mayeso ndi kutumiza. M'mbuyomu, mutha kukweza mafayilo atsopano kudzera pa FTP (palibe amene amachitanso izi, sichoncho?), Ndipo njira ya "kutumiza" idatenga masekondi. Tsopano muyenera kupanga pempho lophatikiza ndikudikirira nthawi yayitali kuti mawonekedwewo afike kwa ogwiritsa ntchito.

Gawo lanjira iyi ndikumanga chithunzi cha Docker. Nthawi zina msonkhano umatenga mphindi, nthawi zina mphindi makumi, zomwe sizingatchulidwe kuti ndizabwinobwino. M'nkhaniyi, titenga ntchito yosavuta yomwe tidzayiyika mu chithunzi, tigwiritse ntchito njira zingapo kuti tifulumizitse kumanga, ndikuyang'ana ma nuances a momwe njirazi zimagwirira ntchito.

Tili ndi chidziwitso chabwino pakupanga ndikuthandizira mawebusayiti azama media: CHIWANDA, The Bell, "New Newspaper", Republic… Osati kale kwambiri ife anakulitsa mbiri yathu ndi kumasula mankhwala webusaiti Chikumbutso. Ndipo ngakhale zatsopano zidawonjezeredwa mwachangu ndipo nsikidzi zakale zidakonzedwa, kutumiza pang'onopang'ono kunakhala vuto lalikulu.

Timatumiza ku GitLab. Timasonkhanitsa zithunzi, kuzikankhira ku GitLab Registry ndikuzitulutsa kuti zipangidwe. Chotalika kwambiri pamndandandawu ndikusonkhanitsa zithunzi. Mwachitsanzo: popanda kukhathamiritsa, kumanga kumbuyo kulikonse kumatenga mphindi 14.

Pamapeto pake, zinaonekeratu kuti sitingakhalenso moyo wotere, ndipo tinakhala pansi kuti tidziwe chifukwa chake zithunzizo zinkatenga nthawi yaitali kuti zisawonongeke. Zimenezi zinachititsa kuti tichepetse nthawi ya msonkhanowo kufika masekondi 30!

Kwa nkhaniyi, kuti tisamangiridwe ku chilengedwe cha Chikumbutso, tiyeni tiwone chitsanzo cha kusonkhanitsa pulogalamu yopanda kanthu ya Angular. Chifukwa chake, tiyeni tipange pulogalamu yathu:

ng n app

Onjezani PWA kwa izo (tikupita patsogolo):

ng add @angular/pwa --project app

Pomwe mapaketi miliyoni a npm akutsitsidwa, tiyeni tiwone momwe chithunzi cha docker chimagwirira ntchito. Docker imapereka mwayi woyika mapulogalamu ndikuyendetsa pamalo akutali otchedwa chidebe. Chifukwa cha kudzipatula, mutha kuyendetsa zotengera zambiri nthawi imodzi pa seva imodzi. Zotengera ndizopepuka kwambiri kuposa makina enieni chifukwa zimayendera molunjika pa kernel. Kuti tigwiritse ntchito chidebe chokhala ndi pulogalamu yathu, choyamba tifunika kupanga chithunzi chomwe timayikamo chilichonse chofunikira kuti pulogalamu yathu igwire ntchito. Kwenikweni, chithunzi ndi kopi ya fayilo yamafayilo. Mwachitsanzo, tengani Dockerfile:

FROM node:12.16.2
WORKDIR /app
COPY . .
RUN npm ci
RUN npm run build --prod

Dockerfile ndi mndandanda wa malangizo; Pochita chilichonse, Docker amasunga zosintha pamafayilo ndikuzikuta pazimene zapita. Gulu lirilonse limapanga wosanjikiza wake. Ndipo chithunzi chomalizidwa ndi zigawo zophatikizidwa pamodzi.

Chofunika kudziwa: gawo lililonse la Docker limatha kubisa. Ngati palibe chomwe chasintha kuyambira pakumanga komaliza, ndiye kuti m'malo motsatira lamulo, docker itenga wosanjikiza wokonzeka. Popeza kuwonjezeka kwakukulu kwa liwiro la kumanga kudzakhala chifukwa cha kugwiritsa ntchito cache, pamene kuyeza liwiro la kumanga tidzatchera khutu kumanga fano ndi cache yokonzeka. Kotero, sitepe ndi sitepe:

1. Timachotsa zithunzizo kwanuko kuti zomwe zidachitika kale zisakhudze mayeso.
   docker rmi $(docker images -q)
2. Timakhazikitsa kumangako koyamba.
   time docker build -t app .
3. Timasintha fayilo ya src/index.html - timatsanzira ntchito ya wopanga mapulogalamu.
4. Timayendetsanso kumangako kachiwiri.
   time docker build -t app .

Ngati malo opangira zithunzi akonzedwa bwino (zambiri pamunsimu), ndiye kuti kumangako kukayamba, Docker adzakhala ndi kale nkhokwe zambiri. Ntchito yathu ndikuphunzira momwe tingagwiritsire ntchito cache kuti kumangako kupite mofulumira momwe tingathere. Popeza tikuganiza kuti kuyendetsa nyumba popanda cache kumachitika kamodzi kokha - koyambirira - titha kunyalanyaza momwe nthawi yoyambayo idachedwera. M'mayesero, kuthamanga kwachiwiri kwa zomangamanga ndikofunika kwa ife, pamene ma cache atenthedwa kale ndipo takonzeka kuphika keke yathu. Komabe, malangizo ena adzakhudzanso kumanga koyamba.

Tiyeni tiyike Dockerfile yomwe yafotokozedwa pamwambapa mufoda ya polojekiti ndikuyamba kumanga. Mindandanda yonse yafupikitsidwa kuti muwerenge mosavuta.

Timagwiritsa ntchito Alpine

Njira ina yosungira pa kukula kwa chithunzi ndikugwiritsa ntchito chithunzi chaching'ono cha kholo. Chithunzi cha makolo ndi chithunzi chomwe chifaniziro chathu chakonzedwa. Chigawo chapansi chikufotokozedwa ndi lamulo FROM mu Dockerfile. Kwa ife, tikugwiritsa ntchito chithunzi chochokera ku Ubuntu chomwe chili kale ndi ma nodejs. Ndipo amalemera...

Choyamba tiyenera kukuuzani chifukwa chake malamulo awiri akuyambitsidwa build. Chowonadi ndi chakuti mumsonkhano wamagulu ambiri chifaniziro chotsatira chidzakhala chamagulu kuchokera pagawo lomaliza. Pankhaniyi, zigawo zochokera m'magawo am'mbuyomu sizingaphatikizidwe pachithunzichi. Chifukwa chake, mukamagwiritsa ntchito chithunzi chomaliza kuchokera pamapangidwe am'mbuyomu, Docker sangathe kupeza zigawo zokonzeka kuti amange chithunzicho ndi ma nodejs (gawo lomanga). Pofuna kuthetsa vutoli, chithunzi chapakati chimapangidwa $IMAGE_NAME-builder-stage ndipo imakankhidwira ku GitHub Packages kuti igwiritsidwe ntchito pomanganso ngati gwero la cache.

Nthawi ya msonkhano wonse inachepetsedwa kukhala mphindi imodzi ndi theka. Theka la miniti limatha kukoka zithunzi zam'mbuyo.

Kuganiziratu

Njira ina yothetsera vuto la cache yoyera ya Docker ndikusuntha zigawo zina mu Dockerfile ina, kumanga padera, kukankhira mu Container Registry ndikuigwiritsa ntchito ngati kholo.

Timapanga chithunzi chathu cha nodejs kuti tipange pulogalamu ya Angular. Pangani Dockerfile.node mu polojekitiyi

FROM node:12.16.2-alpine3.11
RUN apk --no-cache --update --virtual build-dependencies add 
    python 
    make 
    g++

Timasonkhanitsa ndikukankhira chithunzi chapagulu ku Docker Hub:

docker build -t exsmund/node-for-angular -f Dockerfile.node .
docker push exsmund/node-for-angular:latest

Tsopano mu Dockerfile yathu yayikulu timagwiritsa ntchito chithunzi chomalizidwa:

FROM exsmund/node-for-angular:latest as builder
...

Muchitsanzo chathu, nthawi yomanga sinachepe, koma zithunzi zomangidwa kale zitha kukhala zothandiza ngati muli ndi mapulojekiti ambiri ndipo muyenera kuyika zodalira zomwezo pa chilichonse.

Tidawona njira zingapo zofulumizitsa kupanga zithunzi za docker. Ngati mukufuna kuti ntchitoyo ipite mofulumira, yesani kugwiritsa ntchito izi mu polojekiti yanu:

• kuchepetsa nkhani;
• kugwiritsa ntchito zithunzi zazing'ono za makolo;
• multistage msonkhano;
• kusintha dongosolo la malangizo mu Dockerfile kuti mugwiritse ntchito bwino posungira;
