\nKubernetes parimad praktikad. Korralik l\u00f5petamine Terminate<\/a><\/noindex><\/p>\n

Kui olete nagu enamik inimesi, kasutate t\u00f5en\u00e4oliselt ressursse, mis asuvad v\u00e4ljaspool teie klastrit. V\u00f5ib-olla kasutate API Taleo, et saata tekstis\u00f5numeid v\u00f5i anal\u00fc\u00fcsida pilte Google Cloud Vision API kaudu.<\/a><\/noindex><\/p>\n

Kui kasutate sama l\u00f5pp-punkti \u2014 serveri poolt p\u00e4ringute vastuv\u00f5tmise punkti k\u00f5igis oma keskkondades ega kavatse oma servereid Kubernetesesse kolida, siis on t\u00e4iesti normaalne, et teenuse l\u00f5pp-punkt asub otse teie koodis. Siiski on palju teisi stsenaariume. Selles sarjas \"Kubernetes parimad praktikad\" saate teada, kuidas kasutada Kubernetesesse sisseehitatud mehhanisme teenuste avastamiseks nii klastris kui ka v\u00e4ljaspool seda. <\/p>\n

N\u00e4iteks laialdaselt kasutatavatest v\u00e4listest teenustest v\u00f5ib tuua v\u00e4lja andmebaasi, mis t\u00f6\u00f6tab v\u00e4ljaspool Kubernetes klastrit. Erinevalt pilveandmebaasidest, nagu Google Cloud Data Store v\u00f5i Google Cloud Spanner, millele p\u00e4\u00e4seb ligi \u00fche ja sama l\u00f5pp-punkti kaudu, on enamikul andmebaasidest erinevad l\u00f5pp-punktid erinevate olukordade jaoks.
\nTavap\u00e4rase andmebaasi, nagu MySQL ja MongoDB, kasutamise parim praktika h\u00f5lmab tavaliselt erinevate komponentide \u00fchendamist erinevatesse keskkondadesse. V\u00f5ib olla suur masin tootmisandmete jaoks ja v\u00e4iksem masin testkeskkonna jaoks. Igal neist on oma IP-aadress v\u00f5i domeeninimi, kuid te kindlasti ei taha oma koodi muuta, kui liigute \u00fchelt keskkonnalt teisele. Seet\u00f5ttu v\u00f5ite nende aadresside k\u00f5va kodeerimise asemel kasutada Kubernetesi sisseehitatud teenuste avastamist, mis p\u00f5hineb DNS-il, just nagu teeksite natiivsete Kubernetesi teenustega.<\/p>\n

\"Parimad
\n
\nOletame, et k\u00e4itate andmebaasi MongoDB Google Compute Engine'is. J\u00e4ete kinni selle h\u00fcbriidmaailma, kuni suudate selle klastrisse kolida.<\/p>\n

\u00d5nneks saate kasutusele v\u00f5tta Kubernetes'i staatilised teenused, et endale elu veidi lihtsamaks teha. Selles n\u00e4ites olen loonud MongoDB serveri, kasutades Google Cloud Launcherit. Kuna see on loodud samasse v\u00f5rku (v\u00f5i Kubernetes klastrisse VPC), toimub sellele juurdep\u00e4\u00e4s suure j\u00f5udlusega sise-IP-aadressi kaudu.<\/p>\n

\"Parimad
\n
\nGoogle Cloudis on vaikimisi seade, nii et te ei pea midagi seadistama. N\u00fc\u00fcd, kui IP-aadress on olemas, on esimene samm teenuse loomine. V\u00f5ib m\u00e4rgata, et selle teenuse jaoks ei ole \u00fchtegi pod'i valijat. See t\u00e4hendab, et oleme loonud teenuse, mis ei tea, kuhu liiklust suunata. See v\u00f5imaldab k\u00e4sitsi luua endpoint objekti, mis saab liiklust sellest teenusest. <\/p>\n

\"Parimad
\n
\nJ\u00e4rgmine koodin\u00e4ide n\u00e4itab, et l\u00f5pp-punktid m\u00e4\u00e4ravad andmebaasi IP-aadressi, kasutades sama nime mongo, mis on teenusel.<\/p>\n

\"Parimad
\n
\nKubernetes kasutab k\u00f5iki IP-aadresse, et leida l\u00f5pp-punkte, nagu oleks need tavalised Kubernetes pod'id, nii et n\u00fc\u00fcd saate andmebaasi juurde p\u00e4\u00e4seda lihtsa \u00fchendusteksti abil, mis on antud nimi mongodb:\/\/mongo. Sellega ei ole teie koodis \u00fcldse vaja IP-aadresse kasutada.<\/p>\n

Kui tulevikus IP-aadressid muutuvad, saate lihtsalt l\u00f5pp-punkte v\u00e4rskendada uue IP-aadressiga, ja teie rakendusi ei pea mingil moel muutma.<\/p>\n

Kui kasutate andmebaasi, mis asub kolmandal pool, on t\u00f5en\u00e4oliselt hosti omanikud andnud teile \u00fchendamiseks \u00fchtse ressursi identifikaatori URI. Nii et kui teile on antud IP-aadress, saate lihtsalt kasutada eelnevat meetodit. See n\u00e4ide n\u00e4itab, et mul on kaks MongoDB andmebaasi, mis asuvad mLab hostis.<\/p>\n

\"Parimad
\n
\n\u00dcks neist on arendajate andmebaas ja teine \u2014 tootmisandmebaas. Nende andmebaaside \u00fchendusread n\u00e4evad v\u00e4lja j\u00e4rgmised \u2014 mLab pakub teile d\u00fcnaamilist URI-d ja d\u00fcnaamilist porti. Nagu n\u00e4ete, on need erinevad.<\/p>\n

\"Parimad
\n
\nKuna soovime sellest eristuda, kasutame Kubernetes't ja \u00fchendame arendajate andmebaasiga. Saate luua Kubernetes'e v\u00e4lise teenuse nime, mis annab teile staatilise teenuse, mis suunab liikluse v\u00e4list teenust. <\/p>\n

\"Parimad
\n
\nSee teenus rakendab lihtsat CNAME edastamist tasemel kernel, mis m\u00f5jutab tulemuslikkust minimaalselt. T\u00e4nu sellele saate kasutada lihtsamat \u00fchendusreed.<\/p>\n

\"Parimad
\n
\nKuna v\u00e4line nimi kasutab CNAME-i \u00fcmbersuunamist, ei saa seda portide uuenemist teha. Seet\u00f5ttu on see lahendus rakendatav ainult staatilistele portidele ja ei saa kasutada d\u00fcnaamiliste portide puhul. Kuid tasuta mLab Free Tier pakub vaikimisi kasutajale d\u00fcnaamilist porti, ja te ei saa seda muuta. See t\u00e4hendab, et dev ja prod jaoks vajate erinevaid \u00fchenduste k\u00e4sklusi. Halba on see, et porti numbrit tuleb tugevalt kodeerida. Kuidas siis portide \u00fcmbersuunamist t\u00f6\u00f6le saada?<\/p>\n

Esimene samm on saada IP-aadress URI-st. Kui k\u00e4ivitada nslookup k\u00e4sk, hostname v\u00f5i pingida URI, saab andmebaasi IP-aadressi. Kui teenus tagastab mitu IP-aadressi, saab k\u00f5iki neid kasutada objekti l\u00f5pp-punktidena.<\/p>\n

\"Parimad
\n
\nPea meeles, et URI IP-aadressid v\u00f5ivad muutuda ette teatamata, seega on nende kasutamine prod-s \u00fcsna riskantne. Sellise IP-aadressiga on v\u00f5imalik \u00fchenduda kaugandmebaasiga, mitte porti n\u00e4idates. Seega teostab Kubernetes teenus \u00fcsna transparentselt portide \u00fcmbersuunamist.<\/p>\n

\"Parimad
\n
\nKaartimine, ehk v\u00e4liste ressursside seondamine sisemistega, annab teile v\u00f5imaluse paindlikult neid teenuseid tulevikus klastris kasutada, v\u00e4hendades refaktoreerimise vaeva. See h\u00f5lbustab ka haldamist ning annab arusaama, milliseid v\u00e4liseid teenuseid teie ettev\u00f5te kasutab. <\/p>\n

Peagi on see tulemas\u2026<\/p>\n
