- I-Slurm ikuvumela ngempela ukuthi ungene esihlokweni se-Kubernetes noma uthuthukise ulwazi lwakho.
- Abahlanganyeli bajabule. Kukhona abambalwa kuphela abangazange bafunde lutho olusha noma abangakazixazululi izinkinga zabo. Imbuyiselo yemali engenamibandela yosuku lokuqala (“Uma uzwa sengathi i-Slurm ayikufanelanga, sizokubuyisela inani eliphelele lethikithi”) yasetshenziswa umuntu oyedwa kuphela, ezithethelela ngokuthi ulinganisele ngokweqile amandla akhe.
- I-Slurm elandelayo izokwenzeka ekuqaleni kukaSepthemba eSt. I-Selectel, umxhasi wethu waphakade, ayihlinzeki nje ngefu lezitendi, kodwa futhi negumbi layo lenkomfa.
- Siphinda i-Slurm eyisisekelo (Septhemba 9-11) futhi sethula uhlelo olusha: I-DevOps Slurm (Septhemba 4-6).
Iyini i-Slurm futhi ishintshe kanjani?
Ngonyaka odlule, saqhamuka nombono wokuqhuba izifundo ku-Kubernetes. Ngo-August '18, i-Slurm-1 yenzeka: kunzima, nokwethulwa okuqhubekayo (lapho isethulo siqedwa esiteji), nenqwaba yezinkinga zansuku zonke. Izilingo ziyahlangana: abahlanganyeli be-Slurm yokuqala, njenge-Fellowship of the Ring, basaxhumana bodwa.
Yile ndlela i-Slurm-1 ebukeka ngayo
Kwi-Slurm yokuqala, kwavela umqondo wokubamba i-MegaSlurm. Sabuza abantu ukuthi yiziphi izihloko abathanda kuzo, futhi ngo-October saba nezifundo ezithuthukisiwe “Ngesicelo sabahlanganyeli.” Kuvele kwaba umcimbi othokozisayo, kodwa owesikhathi esisodwa. NgoMeyi '19 sesilungiselele isifundo esithuthukile sangempela, esinengqondo kanye nomlando wangaphakathi.
Ngokuhamba konyaka, i-Slurm ishintshile ngokwenhlangano:
- U-Docker no-Anisble bakhishiwe ohlelweni oluyinhloko futhi benza izifundo ezihlukene ze-inthanethi.
- Usekelo lobuchwepheshe oluhlelekile olusiza abafundi baxazulule amaqoqo okufunda.
— Izikhulumi manje sezinokwesekwa kwendlela.
Iqembu elenze i-Slurm 4
Impendulo evela kubahlanganyeli
Kwasethwa elinye irekhodi: ababambiqhaza abayi-170 ku-Slurm eyisisekelo, abangama-75 ku-MegaSlurm.
I-Slurm-4
Abantu abayi-101 kwabayi-170 bagcwalise ifomu lempendulo.
Ingabe u-Kubernetes usecacile?
41 - Angikawaqondi ama-k8 okwamanje, kodwa ngibona ukuthi ngimbe kuphi.
36 — Bengingawazi ama-k8 ngaphambilini, kodwa manje sengikutholile.
23 — Bengazi ama-k8 ngaphambilini, kodwa manje sengiyazi kangcono.
1 - Angifundanga lutho olusha.
0 — Bengingaqondi lutho ngama-k8s.
Uthanda kanjani ukuqina kwe-Slurm?
Abantu abangu-16 bacabanga ukuthi i-Slurm ilula kakhulu futhi ihamba kancane, futhi abantu abangu-14 bacabanga ukuthi inzima kakhulu futhi iyashesha. Kulungile nje kwabanye.
Ingabe usuyixazululile inkinga obuzoya ngayo kwi-Slurm?
90 - Yebo.
11 - Cha.
I-MegaSlurm
Abantu abangu-40 bagcwalise ifomu lempendulo. Abantu abangu-2 bathe kulula kakhulu futhi kuhamba kancane. Umuntu ongu-1 akazange ayixazulule inkinga abeya ngayo eMega. Ezinye zilungile.
Izibuyekezo zesipikha
Uma eSt. Petersburg Slurm ngoFebhuwari kwakukhona abaqalayo abaningi, khona-ke eMoscow Slurm abantu abaningi base bevele bazama uKubernetes. Kube nemibuzo eminingi ethuthukile ekwenze ucabange.
Uma eSt. Petersburg bebuza ukuthi sizoyishicilela nini imfoloko yethu ye-kubespray, khona-ke eMoscow base bebuza ukuthi kungani siphakamisa ukusebenzisa imfoloko yethu futhi singayithathi i-kubespray yasekuqaleni. Lokhu kakade ukucabanga okubucayi kwabadala abaphakathi.
Umkhuba wawunzima, abantu benza amaphutha amaningi, futhi lokho kuhle: udinga ukwenza amaphutha ngenkathi ufunda, hhayi empini.
Besihlala sihlangabezana nemikhawulo ekutholeni izitifiketi, imikhawulo yokulanda kusuka ku-Github, njll. Lokhu ukuphila - kanyekanye satshala amaqoqo angaba ngu-200 efwini le-Selectel. Akekho olungiselela izinsiza zakhe nemikhawulo yalokhu.
