Thaum Lub Tsib Hlis 27-29 peb tab tom tuav plaub Slurm: mob siab rau Kubernetes.
Ntxiv: Cov chav kawm online ntawm Docker, Ansible, Ceph
Peb tau muab los ntawm Slurm cov ncauj lus uas tseem ceeb rau kev ua haujlwm nrog Kubernetes, tab sis tsis cuam tshuam ncaj qha rau k8s. Yuav ua li cas, yog vim li cas thiab dab tsi tshwm sim - nyob rau hauv lub txiav.
Txhua tus neeg koom nrog Slurm 4 yuav nkag mus rau cov kev kawm no.
Tag nrho cov nyiaj rov qab rau thawj hnub
Ntawm St. Petersburg Slurm, ob tug neeg koom nrog tawm mus . Yuav ua li cas kuv tu siab tias nws tsis tuaj yeem rov qab mus rau lub sijhawm thiab koom nrog lawv yam tsis muaj kev sib tham.
Yog tias koj pom dab tsi koj tsis nyiam txog Slurm, thawj hnub sau ntawv mus rau ib qho ntawm cov koom haum. Peb yuav lov tes taw kev nkag mus thiab rov qab them tag nrho cov nqi koom nrog.
Cov kws pab tswv yim
Yog leej twg paub (nws tsim ib lub club ntawm cov thawj coj ua haujlwm), peb tau caw nws mus rau Slurm (los kawm, tsis ua haujlwm). Nws tau cog lus tias yuav qhia txhua tus. Qhov no tsis zoo li yuav txaus siab rau cov thawj coj thiab cov neeg tsim tawm, tab sis nws yuav txaus siab rau cov thawj coj IT.
Slurm yog dab tsi
Slurm-4: Hoob kawm theem pib (Tsib Hlis 27-29)
Tsim los rau cov neeg uas pom Kubernetes thawj zaug lossis xav ua kom lawv txoj kev paub.
Txhua tus neeg koom yuav tsim lawv tus kheej pawg hauv Selectel huab thiab xa daim ntawv thov rau ntawd.

Excursion rau lub keeb kwm
Thawj Slurm yog ib qho kev sim. Cov neeg hais lus ua tiav lawv cov lus tshaj tawm hauv theem, thiab hauv cov neeg tuaj saib zaum cov thawj coj ntawm ib qib uas nws yog lub sijhawm los caw lawv los ua tus hais lus.
Cov chav kawm tiag tiag tau tshwm sim ntawm Slurm thib ob: 80% ntawm cov neeg koom tau pom Kubernetes thawj zaug, thiab ib feem peb tsis tau ua haujlwm nrog Docker.
Nws yog qhov tseeb tias nws nyuaj npaum li cas rau tib neeg los mloog kev qhuab qhia ntawm Docker thaum sawv ntxov thiab ua haujlwm nrog nws hauv kev sib ntaus sib tua thaum yav tsaus ntuj.
Ceph ua rau muaj kev nyuaj heev. Ntxiv mus, muaj 20 tus neeg hauv cov neeg tuaj saib uas xav tau los piav qhia Ceph, thiab lwm 60 tus uas tsis xav tau Ceph kiag li.
Rau qhov thib peb Slurm, peb tau tsiv Docker thiab Ansible mus rau hauv cov webinars cais, tso sijhawm ntau ntxiv rau Kubernetes. Cov kev daws teeb meem tau muab tso rau hauv cov ntsiab lus tseem ceeb thiab tsis tsim nyog rau kev siv: cov lus qhuab qhia tsis txaus siab rau cov neeg paub txog, thiab kev sib tham tsis txaus siab rau cov pib tshiab.
Rau thib plaub Slurm, peb tau kawm online ntawm Docker, Ansible thiab Ceph. Lub tswv yim yog yooj yim: cov neeg uas xav tau nws yuav kawm cov kev xav, cov neeg uas tsis xav tau nws yuav calmly tsis quav ntsej nws. Kev txiav txim los ntawm pab pawg neeg xeem, chav kawm Docker siv sijhawm 6-8 teev. Ansible thiab Ceph tseem tsis tau clocked.
Tsis lees paub:
- kev sim. Qee qhov kev txiav txim siab yuav ua tsis tiav.
- lub platform (Stepik.org) yog crude, thiab peb tsis tau ua hauj lwm nrog nws ua ntej. Tej zaum yuav muaj pob thiab snags.
- Cov chav kawm tau raug sim tsuas yog rau cov neeg ua haujlwm Southbridge. Muaj tseeb koj yuav tau ua kom tiav ib yam dab tsi thaum koj mus.
Tsuas yog lwm hnub hauv kev sib tham ntawm thawj Slurm lawv nco qab tias nws txias thiab lom zem npaum li cas, txawm tias tag nrho cov koom haum txaus ntshai. Thawj qhov kom tau txais kev xav pom tseeb tshaj plaws. Cia peb pom dab tsi tshwm sim rau thawj cov tub ntxhais kawm ntawm cov kev kawm online. 🙂
