🥇Whakaahua Docker mo te tohatoha Tono Wharangi Kotahi

Ko te tono wharangi-kotahi (SPA) he huinga o nga konae JavaScript me HTML, me nga whakaahua me etahi atu rauemi. Na te mea karekau ratou e huri tere, he tino ngawari te whakaputa i runga ipurangi. He maha nga ratonga utu iti me te kore utu mo tenei, timata mai i nga wharangi GitHub ngawari (me etahi me narod.ru) ka mutu ki te CDN penei i a Amazon S3. Heoi, i hiahia ahau ki tetahi atu mea.

I hiahia ahau ki tetahi ahua Docker me te SPA kia ngawari te whakarewahia i roto i te hanga hei waahanga o te roopu Kubernetes, me te miihini o te kaiwhakawhanake-muri kaore e mohio he aha te SPA.

Kua whakatauhia e au nga whakaritenga whakaahua e whai ake nei mo au ake:

ngawari ki te whakamahi (engari ehara i te huihuinga);
te rahi iti e rua mo te kōpae me te RAM;
whirihoranga na roto i nga taurangi taiao kia taea ai te whakamahi i te ahua ki nga taiao rereke;
te tohatoha tino pai o nga konae.

I tenei ra ka korero ahau ki a koe me pehea:

nginx gut;
hanga brotli mai i nga puna;
whakaako i nga konae pateko kia mohio ki nga taurangi taiao;
me pehea te kohikohi i tetahi ahua Docker mai i enei mea katoa.

Ko te kaupapa o tenei tuhinga he whakapuaki i aku wheako me te whakapataritari i nga mema mohio o te hapori ki te whakahee.

Te hanga pikitia mo te huihuinga

Kia iti te rahi o te ahua Docker whakamutunga, me piri koe ki nga ture e rua: he iti rawa nga paparanga me te ahua iti. Ko tetahi o nga whakaahua iti rawa ko te ahua Alpine Linux, na ko taku e whiriwhiri ai. Ko etahi ka tohe ko te Alpine kaore e pai mo te hanga, a he tika pea. Engari ko ahau ake, kare ano au i raru ki a ia, kaore hoki he tautohetohe ki a ia.

Kia iti ake nga paparanga, ka kohia e ahau te ahua ki nga waahanga e 2. Ko te tuatahi he tauira; ko nga taputapu awhina katoa me nga konae rangitahi ka noho ki roto. A i te wahanga whakamutunga ka tuhia e au te putanga whakamutunga o te tono.

Me timata ki te ahua awhina.

Hei whakahiato tono SPA, me hiahia koe ki te node.js. Ka tangohia e ahau te ahua mana, ka tae mai me nga kaiwhakahaere putea npm me te miro. Mo ahau ake, ka taapirihia e ahau te node-gyp, e hiahiatia ana hei hanga i etahi kohinga npm, me te Brotli compressor mai i a Google, ka whai hua ki a maatau i muri mai.

Dockerfile me nga korero.

Kei konei ahau e whawhai ana mo te iti, no reira ka whakakotahihia te ahua e tetahi roopu nui.

Ka kitea te ahua kua oti i konei: https://hub.docker.com/r/alexxxnf/spa-builder. Ahakoa ka tūtohu ahau kia kaua e whakawhirinaki ki nga whakaahua a etahi atu me te kohikohi i a koe ake.

nginx

Ka taea e koe te whakamahi i tetahi tūmau tukutuku ki te tohatoha ihirangi pateko. Kua waia ahau ki te mahi me te nginx, no reira ka whakamahia e au inaianei.

Kei a Nginx tetahi ahua Docker mana, engari he maha rawa nga waahanga mo te tohatoha noa. Ko nga mea kei roto i te tuku ka kitea e tetahi roopu motuhake, i te Dockerfile mana ranei.

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

Ka whakamahia e ahau te Dockerfile hei turanga, engari ka waiho e au ko nga mea e hiahiatia ana hei tohatoha i nga ihirangi pateko. Kaore e taea e taku putanga te mahi i runga i te HTTPS, e kore e tautoko i te whakamanatanga, me te maha atu. Engari ka taea e taku putanga te tohatoha i nga konae kua kopirihia me te Brotli algorithm, he pai ake i te gzip. Ka kopirihia e matou nga konae kotahi; kaore he take ki te mahi i runga i te rere.

Koinei te Dockerfile i mutu i ahau. Ko nga korero i roto i te reo Rusia naku, i te reo Ingarihi - mai i te taketake.

Ka whakatika tonu ahau i te nginx.conf kia taea ai te gzip me te brotli ma te taunoa. Ka whakauruhia ano e ahau nga pane keteroki, na te mea kare rawa tatou e huri i te pateko. A ko te pa whakamutunga ko te whakahoki i nga tono 404 katoa ki te index.html, he mea tika tenei mo te whakatere i te SPA.

Ka taea e koe te tango i te ahua kua oti i konei: https://hub.docker.com/r/alexxxnf/nginx-spa. Ka nui ake te 10,5 MB. Ko te nginx taketake i tango 19,7 MB. Kua makona taku hiahia hakinakina.

Te whakaako i nga tatauranga ki te mohio ki nga taurangi taiao

He aha pea te take e hiahiatia ana i roto i te SPA? Hei tauira, hei tohu ko tehea API RESTful hei whakamahi. Ko te tikanga, ka whakawhitia nga tautuhinga mo te taiao e hiahiatia ana ki te SPA i te wa hanga. Mena ka hiahia koe ki te whakarereke i tetahi mea, me hanga ano e koe te tono. Kaore au e hiahia. E hiahia ana ahau kia hanga kotahi te tono i te atamira CI, me te whirihora i nga mea e tika ana i te atamira CD ma te whakamahi i nga taurangi taiao.

Ae ra, ko nga konae pateko kaore e mohio ki nga taurangi taiao. Na reira, ka whai koe ki te whakamahi i te tinihanga. I te ahua whakamutunga, kaore au e whakarewa i te nginx, engari he tuhinga anga motuhake ka panui i nga taurangi o te taiao, tuhia ki nga konae pateko, ka kopirihia, katahi ka whakawhiti te mana ki te nginx.

Mo tenei kaupapa, ka tukuna e te Dockerfile te tawhā ENTRYPOINT. Me hoatu ki a ia te tuhinga e whai ake nei (ma te Angular hei tauira):

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 $FLAG_FILE echo "Done" fi fi exec "$@"
Kia taea ai e te tuhinga te mahi, me tuhi nga tautuhinga ki nga konae js i tenei puka: ${API_URL}.

Me mahara ko te nuinga o nga SPA hou e taapiri ana i nga tohu ki o raatau konae i te wa e hanga ana. He mea tika tenei kia taea e te kaitirotiro te keteroki i te konae mo te wa roa. Mena ka huri te konae, ka huri tona hash, ka kaha te kaitirotiro ki te tango ano i te konae.

Engari, i roto i taku tikanga, ko te whakarereke i te whirihoranga na roto i nga taurangi taiao e kore e arai i te huringa o te hash file, ko te tikanga me whakakorehia te keteroki tirotiro i etahi atu huarahi. Kaore au i tenei raru na te mea ka tukuna nga whirihoranga rereke ki nga taiao rereke.

Te whakakotahi i te ahua whakamutunga

Ka mutu.
