Bari mu kalli sarrafa shards da kwafin bayanai a cikin Kubernetes.
Na gaba, za mu tattauna batutuwan ajiyar bayanai:

Me yasa muke da damar yin magana game da mai aiki da ClickHouse?

• Muna tallafawa da haɓaka ClickHouse.

Ina so in gaya muku ɗaya daga cikin waɗannan ayyukan. Wannan game da ClickHouse-operator don Kubernetes ne.

A cikin rahotona ina so in tabo batutuwa guda biyu:

• Maudu'in farko shine yadda ma'aikacin sarrafa bayanai na ClickHouse ke aiki a Kubernetes.
• Maudu'i na biyu shine yadda kowane ma'aikaci ke aiki, watau yadda yake mu'amala da Kubernetes.

Koyaya, waɗannan tambayoyin biyu za su haɗu a cikin rahoton nawa.

Wanene zai yi sha'awar sauraron abin da nake ƙoƙarin faɗa?

• Zai fi sha'awa ga waɗanda ke aiki da ma'aikata.

Don mafi kyawun fahimtar abin da za mu tattauna a yau, yana da kyau a san yadda Kubernetes ke aiki da samun horo na girgije.

Menene ClickHouse? Wannan ma'ajin bayanai ne na columnar tare da takamaiman fasali don sarrafa tambayoyin nazari akan layi. Kuma shi ne gaba daya bude tushen.

Kuma yana da mahimmanci a gare mu mu san abubuwa biyu kawai. Kuna buƙatar sanin cewa wannan ma'adanin bayanai ne, don haka abin da zan gaya muku zai yi amfani da kusan kowace rumbun adana bayanai.

Kuma mun fi sha'awar tattauna yadda ake hidimar gungu na ClickHouse a Kubernetes.

Me yasa ake bukata a can? Me ya sa ba za mu iya ci gaba da sarrafa shi da kanmu ba? Kuma amsoshi wani bangare ne na fasaha da wani bangare na kungiyance.

Yaya sauki ko wahala? Wannan, ba shakka, ana iya yin shi da hannu. Amma ba haka ba ne mai sauƙi, saboda muna da ƙarin rikitarwa na sarrafa Kubernetes kanta, amma a lokaci guda ƙayyadaddun ƙayyadaddun ClickHouse suna da yawa. Kuma irin wannan sakamakon tarawa.

Kuma duk tare wannan yana ba da babbar fasahar fasaha, wanda ya zama da wahala a sarrafa shi, saboda Kubernetes yana kawo nasa al'amuran yau da kullun don aiki, kuma ClickHouse yana kawo nasa al'amurran yau da kullun. Musamman idan muna da ClickHouses da yawa, kuma muna buƙatar yin wani abu koyaushe tare da su.

Tare da tsayayyen tsari, ClickHouse yana da adadi mai yawa na batutuwa waɗanda ke haifar da kullun nauyi akan DevOps:

• Lokacin da muke son canza wani abu a cikin ClickHouse, alal misali, ƙara kwafi ko shard, to muna buƙatar sarrafa tsarin.
• Sannan canza tsarin bayanan, saboda ClickHouse yana da takamaiman hanyar sharding. A can kuna buƙatar tsara zane-zanen bayanai, tsara tsarin daidaitawa.
• Kuna buƙatar saita sa ido.

• Kuma zata sake farawa.

Waɗannan ayyuka ne na yau da kullun waɗanda da gaske nake so in sauƙaƙe amfani da su.

Kubernetes kanta yana taimakawa sosai a cikin aiki, amma akan abubuwan tsarin asali.

Kubernetes yana da kyau a sauƙaƙe da sarrafa abubuwa kamar:

• Farfadowa da na'ura.

Wannan yana da kyau, wannan shine madaidaicin alkibla, amma gaba ɗaya bai san yadda ake tafiyar da gungun bayanai ba.

Muna son ƙarin, muna son duk bayanan su yi aiki a Kubernetes.

Ina so in sami wani abu kamar babban maɓallin jan sihiri ɗaya wanda kuke latsawa kuma gungu tare da ayyukan yau da kullun waɗanda ke buƙatar warwarewa ana tura su kuma ana kiyaye su gabaɗayan rayuwarta. ClickHouse cluster a cikin Kubernetes.

Kuma mun yi kokarin samar da mafita da za ta taimaka wajen saukaka aikin. Wannan ma'aikacin ClickHouse ne don Kubernetes daga Altinity.

Operator shiri ne wanda babban aikinsa shi ne sarrafa wasu shirye-shirye, watau Manager.

Kuma ya ƙunshi sifofi na ɗabi'a. Kuna iya kiran wannan ingantaccen ilimin game da yankin batun.

Kuma kawai ma'aikacin shine mataimaki na mutum-mutumi wanda ke hulɗa da microtasks kuma yana taimakawa DevOps.

Me yasa kuke buƙatar afareta? Yana aiki da kyau a cikin nau'i biyu:

• Lokacin da ƙwararren da ke hulɗa da ClickHouse ba shi da isasshen ƙwarewa, amma ya riga ya buƙaci yin aiki da ClickHouse, mai aiki yana sauƙaƙe aikin kuma yana ba ku damar yin aiki da gungu na ClickHouse tare da tsari mai rikitarwa, ba tare da yin cikakken bayani game da yadda duk yake aiki ba. ciki.

Wannan ya fi buƙata ko dai ta waɗanda ke fara tafiya, ko kuma waɗanda ke buƙatar yin aiki da yawa.

Ta yaya tsarin tushen aiki ya bambanta da sauran tsarin? Akwai Helm. Hakanan yana taimakawa shigar da ClickHouse; zaku iya zana taswirar helm, wanda har ma zai shigar da gungu na ClickHouse gaba daya. Mene ne bambanci tsakanin mai aiki da guda ɗaya, misali, Helm?

Babban bambanci na asali shine Helm shine sarrafa kunshin kuma Mai aiki ya ci gaba da gaba. Wannan tallafi ne ga dukan tsarin rayuwa. Wannan ba kawai shigarwa ba ne, waɗannan ayyuka ne na yau da kullum waɗanda suka haɗa da sikelin, sharding, i.e. duk abin da ya kamata a yi a lokacin zagayowar rayuwa (idan ya cancanta, sannan kuma sharewa) - duk abin da mai aiki ya yanke shawarar. Yana ƙoƙarin sarrafa sarrafa kansa da kula da duk tsawon rayuwar software. Wannan shi ne ainihin bambancinsa da sauran hanyoyin da aka gabatar.

Wannan shi ne bangaren gabatarwa, mu ci gaba.

Ta yaya za mu gina ma'aikacin mu? Muna ƙoƙarin tunkarar batun don sarrafa gungu na ClickHouse a matsayin hanya ɗaya.

Anan muna da bayanan shigarwa a gefen hagu na hoton. Wannan YAML ne tare da ƙayyadaddun tari, wanda aka wuce zuwa Kubernetes ta hanyar gargajiya ta kubectl. Can ma’aikacin mu ya dauko shi ya yi sihirinsa. Kuma a fitarwa muna samun makirci mai zuwa. Wannan aiwatarwa ne na ClickHouse a cikin Kubernetes.

Sannan a hankali za mu kalli yadda ainihin ma'aikacin ke aiki, waɗanne ayyuka na yau da kullun za a iya warware su. Za mu yi la'akari da ayyuka na yau da kullun saboda muna da iyakacin lokaci. Kuma ba duk abin da mai aiki zai iya yanke shawara ba ne za a tattauna.

Bari mu fara daga aiki. Aikinmu gaba daya bude tushe ne, saboda haka zaku iya ganin yadda yake aiki akan GitHub. Kuma zaku iya ci gaba daga la'akari da cewa idan kuna son ƙaddamar da shi kawai, to zaku iya farawa tare da Jagoran Farawa Mai Sauri.

Idan kuna son fahimta daki-daki, to muna ƙoƙarin kiyaye takaddun a cikin tsari mai kyau ko žasa.

Bari mu fara da matsala mai amfani. Aiki na farko, inda duk muke so mu fara, shine gudanar da misali na farko ko ta yaya. Ta yaya zan iya ƙaddamar da ClickHouse ta amfani da mai aiki, koda kuwa ban san ainihin yadda yake aiki ba? Muna rubuta takarda, saboda ... Duk sadarwa tare da k8s sadarwa ne ta hanyar bayyanawa.

Wannan shi ne irin wannan hadadden bayani. Abin da muka haskaka a ja shine abin da ya kamata mu mai da hankali akai. Muna tambayar ma'aikacin ya ƙirƙiri gungu mai suna demo.

Waɗannan misalai ne na asali a yanzu. Har yanzu ba a bayyana ma'ajiya ba, amma za mu koma wurin ajiya kaɗan nan gaba. A yanzu, za mu lura da yanayin ci gaban tari.

Mun ƙirƙiri wannan ma'anar. Muna ciyar da shi ga ma'aikacin mu. Ya yi aiki, ya yi sihiri.

Muna kallon wasan bidiyo. Abubuwa uku suna da ban sha'awa: Pod, Sabis guda biyu, da StatefulSet.

Mai aiki ya yi aiki, kuma muna iya ganin ainihin abin da ya halitta.

Ya halitta wani abu kamar wannan. Muna da StatefulSet, Pod, ConfigMap don kowane kwafi, ConfigMap ga duka tari. Ana buƙatar sabis azaman wuraren shiga cikin tari.

Sabis ɗin su ne Sabis na Ma'auni na Load na tsakiya kuma ana iya amfani da su don kowane kwafi, ga kowane shard.

Tarin mu na asali yayi kama da wannan. Yana daga kumburi guda ɗaya.

Mu ci gaba da dagula abubuwa. Muna buƙatar share gungu.

Ayyukanmu suna girma, haɓakawa sun fara. Muna so mu ƙara shard. Muna bin ci gaban. Muna canza ƙayyadaddun ƙayyadaddun mu. Mun nuna cewa muna son shards biyu.

Wannan fayil iri ɗaya ne wanda ke haɓakawa tare da haɓakar tsarin. Adana a'a, za a ƙara yin magana akan ajiya, wannan batu ne daban.

Muna ciyar da ma'aikacin YAML kuma mu ga abin da ya faru.

Ma'aikacin yayi tunani kuma ya sanya abubuwa masu zuwa. Mun riga muna da Pods guda biyu, Sabis uku da, ba zato ba tsammani, 2 StatefulSets. Me yasa 2 StatefulSets?

A kan zane ya kasance kamar haka - wannan shine yanayin mu na farko, lokacin da muke da kwasfa daya.

Ya zama haka. Ya zuwa yanzu komai yana da sauki, an kwafi shi.

Kuma me yasa aka zama StatefulSets guda biyu? Anan muna buƙatar ƙaddamarwa kuma mu tattauna tambayar yadda ake sarrafa Pods a Kubernetes.

Akwai wani abu da ake kira StatefulSet wanda ke ba ka damar ƙirƙirar saitin Pods daga samfuri. Maɓalli mai mahimmanci anan shine Samfura. Kuma zaku iya ƙaddamar da Pods da yawa ta amfani da samfuri ɗaya a cikin StatefulSet ɗaya. Kuma mabuɗin kalmar anan shine "yawan Pods don samfuri ɗaya."

Kuma akwai babban jaraba don yin gabaɗayan tari, tare da tattara shi cikin StatefulSet ɗaya. Zai yi aiki, babu matsala tare da shi. Amma akwai gargadi guda ɗaya. Idan muna son tara gungu iri-iri, watau, daga nau'ikan ClickHouse da yawa, to tambayoyinmu sun fara. Ee, StatefulSet na iya yin sabuntawar birgima, kuma a can za ku iya fitar da sabon sigar, bayyana cewa kuna buƙatar gwada nodes da yawa a lokaci guda.

Amma idan muka fitar da aikin kuma muka ce muna son yin gungu mai ban sha'awa gaba ɗaya kuma ba ma son canzawa daga tsohuwar sigar zuwa sabon ta amfani da sabuntawar birgima, amma kawai muna son ƙirƙirar tari iri-iri duka biyu cikin sharuddan. na daban-daban iri na ClickHouse da kuma cikin sharuddan ajiya daban-daban. Muna so, alal misali, yin wasu kwafi akan faifai daban-daban, akan masu jinkirin, gabaɗaya, don gina gungu iri-iri. Kuma saboda gaskiyar cewa StatefulSet yana yin daidaitaccen bayani daga samfuri ɗaya, babu wata hanyar yin wannan.

Bayan wani tunani, sai aka yanke shawarar cewa za mu yi haka. Muna da kowane kwafi a cikin nasa StatefulSet. Akwai wasu kura-kurai ga wannan maganin, amma a aikace duk mai aiki ne ya tattara shi gaba ɗaya. Kuma akwai fa'idodi da yawa. Za mu iya gina ainihin gungu da muke so, alal misali, cikakken nau'in nau'i. Saboda haka, a cikin gungu wanda muke da shards guda biyu tare da kwafi ɗaya, za mu sami 2 StatefulSets da 2 Pods daidai saboda mun zaɓi wannan hanyar saboda dalilan da aka ambata a sama don samun damar gina gungu iri-iri.

Mu koma ga matsalolin aiki. A cikin gungun mu muna buƙatar daidaita masu amfani, watau. kuna buƙatar yin wasu sanyi na ClickHouse a cikin Kubernetes. Mai aiki yana ba da duk damar yin hakan.

Za mu iya rubuta abin da muke so kai tsaye a cikin YAML. Ana tsara duk zaɓuɓɓukan daidaitawa kai tsaye daga wannan YAML zuwa cikin saitunan ClickHouse, waɗanda kuma ana rarraba su cikin gungu.

Kuna iya rubuta shi kamar haka. Wannan misali ne. Ana iya rufaffen kalmar sirri. Lallai ana tallafawa duk zaɓuɓɓukan sanyi na ClickHouse. Ga misali kawai.

Ana rarraba saitin tari azaman ConfigMap. A aikace, sabuntawar ConfigMap baya faruwa nan take, don haka idan tarin yana da girma, to tsarin tura tsarin yana ɗaukar ɗan lokaci. Amma duk wannan ya dace sosai don amfani.

Bari mu dagula aikin. Tarin yana tasowa. Muna son yin kwafin bayanai. Wato mun riga mun sami shards guda biyu, kwafi ɗaya kowanne, kuma an daidaita masu amfani. Muna girma kuma muna son yin kwafi.

Me muke bukata don kwafi?

Muna buƙatar ZooKeeper. A cikin ClickHouse, ana gina kwafi ta amfani da ZooKeeper. Ana buƙatar ZooKeeper don kwafin ClickHouse daban-daban su sami yarjejeniya game da waɗanne tubalan bayanai ke kan abin ClickHouse.

ZooKeeper na iya amfani da kowa. Idan kamfani yana da ZooKeeper na waje, to ana iya amfani dashi. Idan ba haka ba, zaku iya shigar da shi daga ma'ajiyar mu. Akwai mai sakawa wanda ke sauƙaƙa wannan duka.

Kuma zane-zanen hulɗar tsarin gaba ɗaya ya juya kamar haka. Muna da Kubernetes azaman dandamali. Yana aiwatar da ma'aikacin ClickHouse. Na dauki hoton ZooKeeper anan. Kuma mai aiki yana hulɗa tare da ClickHouse da ZooKeeper. Wato sakamakon mu'amala.

Kuma duk wannan ya zama dole don ClickHouse don samun nasarar kwafin bayanai a cikin k8s.

Muna ƙara sassa biyu zuwa bayanin mu. Na farko shine inda za'a sami ZooKeeper, wanda zai iya kasancewa ko dai cikin Kubernetes ko na waje. Wannan siffa ce kawai. Kuma muna yin odar kwafi.

Kuma lokaci yayi da za a ƙara aiki na gaba. Za mu ƙara ma'ajiya na dindindin.

Don Ma'ajiyar Dagewa muna da zaɓuɓɓuka daban-daban.

Idan muna gudana a cikin mai ba da girgije, alal misali, ta amfani da Amazon, Google, to akwai babban jaraba don amfani da ajiyar girgije. Yana da matukar dacewa, yana da kyau.

Kuma saboda ClickHouse yana mai da hankali musamman kan yawan aiki, mutum na iya cewa yana matse duk abin da zai iya, wanda shine dalilin da ya sa yawancin abokan ciniki ke ƙoƙarin fitar da mafi girman yawan aiki.

Kuma don samun fa'ida daga gare ta, muna buƙatar ma'ajiyar gida.

Kubernetes yana ba da abstractions guda uku don amfani da ma'ajiyar gida a Kubernetes. Wannan:

Bari mu dubi yadda suka bambanta da kuma yadda suke kama.

Da fari dai, a cikin dukkan hanyoyin guda uku muna da ajiya - waɗannan fayafai ne na gida waɗanda ke kan kullin k8s na zahiri ɗaya. Amma suna da wasu bambance-bambance.

Bari mu fara da mafi sauƙi, watau emptyDir. Menene wannan a aikace? A cikin ƙayyadaddun mu, muna tambayar tsarin kwantena (mafi yawancin Docker) don ba mu damar shiga babban fayil akan faifan gida.

A aikace, Docker yana ƙirƙirar babban fayil na wucin gadi a wani wuri tare da nasa hanyoyin kuma ya kira shi dogon zanta. Kuma yana ba da hanyar sadarwa don samun dama gare shi.

Ta yaya wannan zai yi aiki da hikima? Wannan zai yi aiki a saurin faifai na gida, watau. Wannan shine cikakken damar zuwa dunƙule ku.

Amma wannan harka yana da nasa drawback. Dagewa yana da shakka a cikin wannan al'amari. A karon farko Docker yana motsawa tare da kwantena, Mai dagewa ya ɓace. Idan Kubernetes yana so ya motsa wannan Pod zuwa wani faifai don wasu dalilai, bayanan za su ɓace.

Wannan tsarin yana da kyau ga gwaje-gwaje, saboda ya riga ya nuna saurin al'ada, amma ga wani abu mai tsanani wannan zaɓi bai dace ba.

Don haka akwai hanya ta biyu. Wannan shine hostPath. Idan ka kalli faifan da ya gabata da kuma wannan, za ka iya ganin bambanci ɗaya kawai. Babban fayil ɗinmu ya matsa daga Docker kai tsaye zuwa kumburin Kubernetes. Yana da ɗan sauki a nan. Muna ƙayyade hanyar kai tsaye akan tsarin fayil ɗin gida inda muke son adana bayanan mu.

Wannan hanya tana da amfani. Wannan ya riga ya zama na gaske na dindindin, kuma na al'ada a wancan. Za mu sami bayanan da aka rubuta akan faifai a wasu adireshi.

Amma ba mu kaɗai ne muke buƙatar wannan buƙata ba, don haka ma'aikatan Kubernetes su ma sun fahimci cewa mutane suna son samun damar yin amfani da faifai na zahiri, don haka suna samar da Layer na uku.

Amma muna son yin aiki ba kawai tare da pods da StatefulSets ba, muna son ƙirƙirar ClickHouseInstallation, watau wani abu na nau'in ClickHouse, don yin aiki da shi gaba ɗaya. Ya zuwa yanzu babu yiwuwar haka.

Amma K8s yana da abubuwa masu kyau masu zuwa. Muna son mu sami wani wuri kamar wannan hadadden mahallin inda za a haɗa tarin mu daga kwas ɗin da StatefulSet.

Kuma me ya kamata a yi don wannan? Na farko, Ma'anar Albarkatun Al'ada ta shigo cikin hoton. Menene shi? Wannan siffa ce ta K8s, cewa za ku sami ƙarin nau'in bayanai guda ɗaya, cewa muna son ƙara kayan aiki na al'ada a cikin kwafsa, StatefulSet, wanda zai kasance mai rikitarwa a ciki.
