🥇Umfanekiso weDocker wephepha elinye losasazo lwesicelo

I-Single-page Application (SPA) yiseti yeJavaScript engatshintshiyo kunye neefayile zeHTML, kunye nemifanekiso kunye nezinye izixhobo. Ngenxa yokuba azitshintshi ngokuguqukayo, ukuzipapasha kwi-intanethi kulula kakhulu. Kukho inani elikhulu leenkonzo ezingabizi kwaye zisimahla kule nto, ukuqala ngamaPhepha e-GitHub alula (kunye nakwabanye kunye ne-narod.ru) kwaye iphele nge-CDN efana ne-Amazon S3. Noko ke, ndandifuna enye into.

Bendifuna umfanekiso weDocker one-SPA ukuze ube nokusungulwa ngokulula zombini kwimveliso njengenxalenye yeqela le-Kubernetes, nakumatshini womphuhlisi osemva ongayaziyo ukuba yintoni i-SPA.

Ndizimisele ezi mfuno zilandelayo zomfanekiso:

ukusetyenziswa lula (kodwa hayi indibano);
ubuncinci besayizi zombini ngokwe diski kunye ne-RAM;
uqwalaselo ngokusebenzisa izinto eziguquguqukayo zemo engqongileyo ukuze umfanekiso usetyenziswe kwiindawo ezahlukeneyo;
unikezelo olusebenzayo lweefayile.

Namhlanje ndiza kukuxelela indlela:

ithumbu nginx;
ukwakha brotli ukusuka kwimithombo;
fundisa iifayile ezingashukumiyo ukuqonda izinto ezahlukeneyo zokusingqongileyo;
kwaye ngokuqinisekileyo ungahlanganisa njani umfanekiso weDocker kuyo yonke le nto.

Injongo yeli nqaku kukwabelana ngamava am kwaye ndixhokonxe amalungu oluntu anamava ukuba agxeke ngendlela eyakhayo.

Ukwakha umfanekiso wendibano

Ukwenza umfanekiso weDocker wokugqibela ube mncinci ngobukhulu, kufuneka unamathele kwimithetho emibini: ubuncinci bemigangatho kunye nomfanekiso wesiseko esincinci. Omnye weyona mifanekiso mincinci isiseko ngumfanekiso weAlpine Linux, ke yile nto ndiza kuyikhetha. Abanye banokuthi iAlpine ayifanelekanga ukuveliswa, kwaye banokuthi balungile. Kodwa mna ngokwam andizange ndanengxaki naye kwaye akukho zingxabano ezichasene naye.

Ukuba nemigangatho embalwa, ndiza kudibanisa umfanekiso kwizigaba ezi-2. Eyokuqala yidrafti; zonke izinto ezincedisayo kunye neefayile zexeshana ziya kuhlala kuyo. Kwaye kwinqanaba lokugqibela ndiya kubhala kuphela inguqu yokugqibela yesicelo.

Masiqale ngomfanekiso oncedisayo.

Ukuze uqokelele isicelo se-SPA, udla ngokufuna i-node.js. Ndiza kuthatha umfanekiso osemthethweni, oza kunye ne-npm kunye nabaphathi bephakheji yentambo. Egameni lam, ndiza kongeza i-node-gyp, efunekayo ukwakha iiphakheji ze-npm, kunye ne-Brotli compressor evela kuGoogle, eya kuba luncedo kuthi kamva.

Dockerfile ngezimvo.

Sele ndilapha ndilwela ubuncinci, ngoko umfanekiso uhlanganiswe liqela elinye elikhulu.

Umfanekiso ogqityiweyo unokufunyanwa apha: https://hub.docker.com/r/alexxxnf/spa-builder. Nangona ndincoma ukuba ungathembeli kwimifanekiso yabanye abantu kwaye uqokelele eyakho.

nginx

Ungasebenzisa nayiphi na iseva yewebhu ukusabalalisa umxholo omileyo. Ndiqhele ukusebenza nge nginx, so ndizoyisebenzisa ngoku.

I-Nginx inomfanekiso we-Docker esemthethweni, kodwa ineemodyuli ezininzi kakhulu zokusasazwa kwe-static. Ziziphi ezibandakanyiweyo ekuhanjisweni zingabonwa liqela elikhethekileyo okanye kwiDockerfile esemthethweni.

$ docker run --rm nginx:1-alpine nginx -V

Ndiza kusebenzisa i-Dockerfile njengesiseko, kodwa ndiya kushiya kuyo kuphela into efunekayo ukusabalalisa umxholo omileyo. Inguqulelo yam ayizukwazi ukusebenza nge-HTTPS, ayizukuxhasa ugunyaziso, nokunye okuninzi. Kodwa inguqulelo yam iya kuba nakho ukusasaza iifayile ezicinezelwe nge-algorithm yeBrotli, esebenza kancinci kunegzip. Siza kucinezela iifayile kube kanye; akukho mfuneko yakwenza oku kubhabho.

Le yiDockerfile endigqibe ngayo. Izimvo ngesiRashiya zezam, ngesiNgesi - ukusuka ekuqaleni.

Ndizakulungisa ngoko nangoko nginx.conf ukuze i-gzip kunye ne-brotli zisebenze ngokungagqibekanga. Ndiza kubandakanya i-caching headers, kuba asisoze sitshintshe i-static. Kwaye uchuku lokugqibela luya kuba kukwalathisa zonke izicelo ezingama-404 kwi-index.html, oku kuyimfuneko kwi-navigation kwi-SPA.

Ungakhuphela umfanekiso ogqityiweyo apha: https://hub.docker.com/r/alexxxnf/nginx-spa. Ithatha i-10,5 MB. I-nginx yoqobo ithathe i-19,7 MB. Umdla wam wezemidlalo wanelisiwe.

Ukufundisa i-statics ukuqonda izinto eziguquguqukayo zokusingqongileyo

Kutheni iisetingi zinokufuneka kwi-SPA? Umzekelo, ukuze uchaze ukuba yeyiphi i-RESTful API emayisetyenziswe. Ngokuqhelekileyo, iisetingi zendawo efunekayo zikhutshelwa kwi-SPA kwinqanaba lokwakha. Ukuba ufuna ukutshintsha into ethile, kuya kufuneka uphinde uyakhe isicelo. andiyifuni. Ndifuna isicelo sakhiwe kube kanye kwinqanaba leCI, kwaye iqwalaselwe kangangoko kuyimfuneko kwinqanaba le-CD usebenzisa izinto eziguquguqukayo zokusingqongileyo.

Ewe kunjalo, iifayile ezimileyo ngokwazo aziqondi naziphi na izinto eziguquguqukayo zokusingqongileyo. Ngoko ke, kuya kufuneka usebenzise iqhinga. Kumfanekiso wokugqibela, andiyi kusungula i-nginx, kodwa iskripthi esikhethekileyo seqokobhe esiya kufunda izinto eziguquguqukayo zendalo, zibhale kwiifayile ezimileyo, zizicinezele, kwaye emva koko udlulisele ulawulo kwi-nginx.

Ngale njongo, iDockerfile ibonelela nge-ENTRYPOINT iparamitha. Masimnike esi script silandelayo (sisebenzisa i-Angular njengomzekelo):

docker-entrypoint.sh

#!/bin/sh set -e FLAG_FILE="/configured" TARGET_DIR="/etc/nginx/html" replace_vars () { ENV_VARS='$(awk 'BEGIN{for(v in ENVIRON) print " quot;v}')' # В Angular ищем плейсхолдеры в main-файлах for f in "$TARGET_DIR"/main*.js; do # envsubst заменяет в файлах плейсхолдеры на значения из переменных окружения echo "$(envsubst "$ENV_VARS" < "$f")" > "$f" done } compress () { for i in $(find "$TARGET_DIR" | grep -E ".css$|.html$|.js$|.svg$|.txt$|.ttf

quot;); do # Используем максимальную степень сжатия gzip -9kf "$i" && brotli -fZ "$i" done } if [ "$1" = 'nginx' ]; then # Флаг нужен, чтобы выполнить скрипт только при самом первом запуске if [ ! -e "$FLAG_FILE" ]; then echo "Running init script" echo "Replacing env vars" replace_vars echo "Compressing files" compress touch $FLAG_FILE echo "Done" fi fi exec "$@"
Ukuze iskripthi senze umsebenzi waso, useto kufuneka lubhalwe kwiifayile zejs kule fomu: ${API_URL}.

Kuyaphawuleka ukuba uninzi lwee-SPA zanamhlanje zongeza i-hashes kwiifayile zazo xa zisakha. Oku kuyimfuneko ukwenzela ukuba isikhangeli singakwazi ukugcina ifayile ngokukhuselekileyo ixesha elide. Ukuba ifayile iyatshintsha, ke i-hash yayo iya kutshintsha, leyo iya kunyanzela umkhangeli ukuba akhuphe ifayile kwakhona.

Ngelishwa, kwindlela yam, ukutshintsha uqwalaselo ngokusebenzisa izinto eziguquguqukayo zemo engqongileyo akukhokeleli kutshintsho kwihashi yefayile, okuthetha ukuba i-cache yesikhangeli kufuneka ingasebenzi ngenye indlela. Andinayo le ngxaki kuba ulungelelwaniso olwahlukileyo lubekwe kwindawo ezahlukeneyo.
