Gore rino, Plesk yakafunga kutumira vanhu vakati wandei kuKubeCon, iyo yekutanga Kubernetes chiitiko munyika. Iko hakuna makonferensi akasarudzika muRussia nezvenyaya iyi. Ehe, isu tiri kutaura nezve K8s, uye munhu wese anoida, asi hapana kumwe kunoitwa makambani mazhinji kudaro anodzidzira anoungana munzvimbo imwechete. Ndakaita kunge ndiri mumwe wevatori vechikamu sezvo ndiri kushanda papuratifomu yakavakirwa paKubernetes.
Pamusoro pesangano
Kukura kwemusangano kunoshamisa: vatori vechikamu 7000, nzvimbo huru yekuratidzira. Kuchinja kubva kune imwe horo kuenda kune imwe kwakatora 5-7 maminetsi. Pakanga pane mishumo makumi matatu pamisoro yakasiyana panguva imwe chete. Paive nenhamba huru yemakambani aive nemastands awo, mamwe acho aipa zvakawanda zvakanaka uye mamwe mibairo mikuru, uye aipawo marudzi ese emhando yeT-shirts, zvinyoreso nezvimwe zvinoyevedza. . Kukurukurirana kwose kwaiitwa muchiRungu, asi handina kumbosangana nematambudziko. Kana ichi chiricho chete chikonzero nei usingaendi kumisangano yekunze, enda mberi. Chirungu muIT chiri nyore pane chenguva dzose Chirungu nekuda kwehuwandu hwemashoko akajairika aunonyora uye kuverenga mazuva ese mukodhi uye zvinyorwa. Pakanga pasinawo matambudziko nemaonero ezvinyorwa. Ruzivo rwakawanda rwakaiswa mumusoro mangu. Manheru, ndakafanana nesevha iyo yavakatora mukana wekufashukira kwebuffer ndokuidururira mundangariro.
Nezvemishumo
Ndinoda kutaura muchidimbu nezvemishumo yandainyanya kufarira uye ndingakurudzira kutarisa.
Chirevo ichi chakaita mucherechedzo chaiwo pandiri nekuti yakabata pamarwadzo mazhinji. Tine masevhisi mazhinji akasiyana, anotsigirwa uye akagadziridzwa nevanhu vakasiyana pachikwata. Isu tinotevera zvivakwa sekusvika kwekodhi, asi pane zvimwe zvisina kugadziriswa. Iko kune repository ine Ansible kodhi, asi iyo yazvino mamiriro uye inventory zvakachengetwa nemugadziri achimhanyisa script pamushini, uye zvikwereti zviripo. Rumwe ruzivo runogona kuwanikwa mukuwirirana, asi hazvisi pachena nguva dzose kuti kupi. Iko hakuna kwaunogona kungodzvanya bhatani uye zvese zvichanaka. Inokurudzirwa kuita tsananguro uye kuisa mune repository kwete chete kodhi, asiwo maturusi ekutumira. Rondedzera kwaunowana nyika uye makiredhiti, ita Isa uye unakirwe nemhedzisiro. Ini ndoda kurongeka kwakawanda mumasevhisi, ini ndichatevera kuburitswa kweCNAB, kuishandisa ini, kuishandisa, uye kuvanyengetedza. Nzira yakanaka yekugadzira Readme mu turnip.
Ruzivo rwakawanda pane rake kana uchinyora vashandisi. Ini ndinoona mushumo seunofanirwa-kuona kune avo vari kuronga kunyora yavo opareta yeKubernetes. Zvese zvinhu zvakaita semastatus, kuunganidzwa kwemarara, kukwikwidza uye zvimwe zvese zvinotariswa ipapo. Inodzidzisa zvakanyanya. Ini ndaifarira chaizvo quote kubva kune inoenderera mavhoriyamu Kubernetes kodhi:
K8s inotengesa kuoma kwekubatanidzwa mukufarira kuita nyore kuita.
Chirevo ichi chinoratidza zvakadzama chimwe chezvinhu zvakakosha zvekuvaka zve cluster - iyo ndege yekudzora, iyo seti yevatongi. Basa ravo uye zvivakwa zvinotsanangurwa, pamwe chete nemisimboti yekutanga yekugadzira yako controller uchishandisa muenzaniso weiyo iripo.
Imwe yeakanyanya mapoinzi kurudziro yekusavhara mamiriro asina kujairika kuseri kwemaitiro chaiwo emutongi, asi kushandura maitiro neimwe nzira kuratidza sisitimu kuti matambudziko amuka.
Chiitiko chinonakidza kwazvo, ruzivo rwakawanda nemabikirwo pamusoro pezvaunoda kufunga nezvazvo kana uine basa rakanyanyisa. Ivo vakapinda muKubernetes zvakanaka uye vanotsigira 50 masumbu. Vakataura pamusoro pezvinhu zvose zvekudzvanya zvibereko zvakanyanya. Ini ndinokurudzira kutarisa mushumo ndisati ndaita chero sarudzo dzehunyanzvi pamasumbu.
Chirevo mushure mezvo ndakaona kuti ini zvechokwadi ndinofanira kuedza Loki yematanda musumbu uye, zvichida, gara nayo. Chinonyanya kukosha: elastic inorema. Grafana aida kugadzira mhinduro isina kuremerwa, ine scalable yakakodzera kugadzirisa matambudziko. Mhinduro yakazova yakanaka: Loki anosarudza meta ruzivo kubva Kubernetes (mavara, saPrometheus), uye anoisa matanda maererano navo. Saka, iwe unogona kusarudza zvidimbu zvegidhi nebasa, tsvaga chaiyo sub, sarudza yakatarwa nguva, sefa nekodhi yekukanganisa. Masefa aya anoshanda pasina tsvakiridzo yemavara. Saka, nekudzikisa zvishoma nezvishoma kutsvaga, unogona kusvika kune chaiyo kukanganisa kwaunoda. Pakupedzisira, kutsvaga kuchiri kushandiswa, asi sezvo denderedzwa yakaderedzwa, kukurumidza kunokwana pasina indexing. Nekudzvanya pairi, mamiriro ezvinhu anoremerwa - mitsetse miviri pamberi uye mitsetse miviri yelogi mushure. Nekudaro, zvinoita sekunge kutsvaga faira rine matanda uye grepping pairi, asi zvishoma zviri nyore uye mune imwechete interface pane metrics. Inogona kuverenga nhamba yezvaitika zvekutsvaga kutsvaga. Mibvunzo yekutsvaga pachayo yakafanana nemutauro wePrometheus uye inotaridzika nyore. Mukurukuri akakwevera pfungwa dzedu kuidi rokuti mhinduro haina kunyatsokodzera ongororo. Ini ndinoikurudzira kune chero munhu anoda matanda, zviri nyore kuverenga.
Maitiro e canary uye blue-green deployment anonyatso kuratidzwa. Ndinopa zano kune avo vasati vafemerwa kuti vatarise iyo report. Vatauri vachapa mhinduro nenzira yekuwedzera kune inovimbisa CI-CD system ARGO. Kutaura kweChirungu kwemukurukuri kubva kuRussia kuri nyore kuteerera pane kutaura kwevamwe vatauri.
Chimwe chezvinhu zvakanyanya kuoma zve cluster manejimendi inoramba ichimisa chengetedzo, kunyanya kodzero dzekuwana kune zviwanikwa. Yakavakwa-mukati maK8s ekutanga anotendera iwe kuti ugadzirise mvumo sezvaunoda. Nzira yekuvachengeta sei pasina kurwadziwa? Nzira yekunzwisisa sei zviri kuitika nekodzero dzekuwana uye kugadzirisa mabasa akagadzirwa? Chirevo ichi hachingope tarisiro yezvishandiso zvakati wandei zvekubvisa mvumo muk8s, asi inopawo kurudziro yekuvaka yakapusa uye inoshanda marongero.
Mimwe mishumo
Ini handizvikurudzire. Vamwe vaive kaputeni, vamwe, pane kudaro, vaive vakaoma kwazvo. Ndinokupa zano kuti usvetukire mune ino playlist utarise zvese zvakanyorwa sekiyi.Izvi zvinokutendera kuti utarise zvakanyanya indasitiri yakatenderedza Cloud Native Apps, wobva wadzvanya ctrl+f wotsvaga mazwi makuru, makambani, zvigadzirwa uye nzira dzekufarira.
Heino chinongedzo kune playlist ine mishumo, teerera pazviri
About company stands
PaHaproxy stand ndakapiwa mwana wangu T-shirt. Ini ndinokahadzika kuti nekuda kweizvi ndichatsiva Nginx ne haproxy mukugadzira, asi ndinovarangarira zvakanyanya. Ndiani anoziva zvichaitwa nevaridzi vatsva neNginx.
Paive nehurukuro pfupi paIBM booth mazuva ese matatu, uye vakakwevera vanhu mukati nekudzura Oculus Go, Beats mahedhifoni, uye quadcopter. Waifanira kunge uri pastand kwehafu yeawa yose. Kaviri mumazuva matatu ndakaedza rombo rangu - hazvina kuitika. VMWare neMicrosoft vakapawo mharidzo pfupi.
Pakumira kweUbuntu, ndakaita zvaiita senge munhu wese ari kuita - ndakatora foto naShuttleworth. Mukomana aishamwaridzana, akafara kudzidza kuti ndanga ndichiishandisa kubva 8.04 uye kuti sevha yakashanda nayo kwemakore gumi pasina dist upgrade pasina kana kumbozorora (kunyangwe pasina kuwana Internet).
Ubuntu iri kucheka MicroK8s yayo - Inokurumidza, Chiedza, Kumusoro Mugadziri Kubernetes
Ndakanga ndisingakwanisi kupfuura Dmitry Stolyarov akaneta, ndakataura naye pamusoro pehupenyu hwakaoma hwezuva nezuva hwemainjiniya anotsigira Kubernetes. Iye achagovera kuverengwa kwemishumo kune vaanoshanda navo, asi ari kugadzirira imwe nzira itsva yekupa zvinyorwa. Ndakakukurudzira kuti unyore kuFlant's YouTube chiteshi.
IBM, Cisco, Microsoft, VMWare yakaisa mari yakawanda mumastand. Open source komuredhi vaive nemastand ane mwero. Ndakataura nevamiririri veGrafana panzvimbo uye vakandikurudzira kuti ndinofanira kuedza Loki. Kazhinji, zvinoita sekunge kutsvaga kwemavara akazara muhurongwa hwekutema matanda kunodiwa chete kune analytics, uye masisitimu ari padanho reLoki anokwana kugadzirisa matambudziko. Ndakataura nevagadziri vePrometheus. Ivo havaronge kuita kwenguva refu kuchengetedza kwema metrics uye data downsampling. Inorayirwa kutarisa cortex uye thanos semhinduro. Paive nemastands akawanda, zvakatora zuva rese kuti ndivaone vese. A gumi nemaviri ekutarisa mhinduro sevhisi. Masevhisi mashanu ekuchengetedza. Mabasa mashanu ekuita. Makumi nemaviri maUI eKubernetes. Kune vazhinji vanopa k8s sevhisi. Wese munhu anoda chikamu chavo chemusika.
Amazon neGoogle vakarenda mapatio ane huswa hwekugadzira padenga uye vakaisa maroja ezuva ipapo. Amazon yakatambidza makomichi ndokudurura lemonade, uye pachigadziko chakataura nezve hunyanzvi mukushanda nezviitiko. Google yakapa makuki ane Kubernetes logo ndokugadzira inotonhorera nzvimbo yemifananidzo, uye panzvimbo yekumira ndakaredza hove dzebhizinesi hombe.
About Barcelona
Mukudanana neBarcelona. Ndakanga ndiripo kechipiri, kekutanga muna 2012 parwendo rwekuona nzvimbo. Izvi zvinoshamisa, asi zvinhu zvakawanda zvakauya mupfungwa, ndakakwanisa kuudza vandinoshanda navo zvakawanda, ndaive mini-guide. Mhepo yakachena yemugungwa yakabva yabvisa zvinhu zvangu. Zvokudya zvegungwa zvinonaka, paella, sangria. Kudziya kwakanyanya, kwezuva zvivakwa. Nhamba shoma yepasi, yakawanda yegirini. Takafamba makiromita angangoita 50 mumazuva matatu aya, uye ndinoda kufamba-famba muguta rino kakawanda. Zvese izvi mushure memishumo, manheru.
Chii chikuru chandakanzwisisa
Ndinofara zvikuru kuti ndakawana mukana wekupinda musangano uyu. Akarongedza mumasherufu zvakanga zvisati zvarongeka. Akandikurudzira uye akaita kuti zvimwe zvinhu zvive pachena.
Pfungwa yakamhanya seshinda tsvuku: Kubernetes haisi yekupedzisira, asi chishandiso. Chikuva chekugadzira mapuratifomu.
Uye iro basa guru rekufamba kwese: kuvaka uye mhanyisa scalable application
Nhungamiro huru dziri kushanda nenharaunda dzanyatsojeka. Anenge maitiro gumi nemaviri ezvikumbiro akaonekwa panguva imwe chete, rondedzero yezvipi uye maitiro ekuita kwezvivakwa zvese zvakaonekwa. Kana uchida, unogona kudana aya maitiro:
- Dynamic environments
- Veruzhinji, makore akasanganiswa uye akavanzika
- Containers
- Service mesh
- Microservices
- Zvivakwa zvisingachinjiki
- Declarative API
Aya matekiniki anobvumidza iwe kuvaka masisitimu ane anotevera maitiro:
- Kudzivirirwa pakurasikirwa nedata
- Elastic (inogadzirisa kurodha)
- Serviced
- Zvinoonekwa (mbiru nhatu: kutarisa, kutema miti, kutsvaga)
- Kuve nekugona kuburitsa shanduko huru kazhinji uye nekufanotaura zvakachengeteka.
CNCF inosarudza akanakisa mapurojekiti (runyoro rudiki) uye inosimudzira zvinotevera zvinhu:
- Smart Automation
- open source
- Rusununguko rwekusarudza mupi webasa
Kubernetes yakaoma. Zviri nyore nemafungiro uye muzvikamu, asi zvakaoma sese. Hapana akaratidza mhinduro-mune-imwe. Musika wek8s sevhisi, uye zvechokwadi musika wese, isango kumadokero: rutsigiro runotengeswa zvese madhora makumi mashanu nemadhora zana pamwedzi. Munhu wese anopinda zvakadzika mune chimwe chikamu uye anochera mazviri. Vamwe vari mukutarisa uye dashboards, vamwe mukuita, vamwe mukuchengetedza.
K8S, zvese zviri kutanga!
