Musi waMay 27-29 tiri kubata yechina Slurm: yakasimba paKubernetes.
Bhonasi: online makosi paDocker, Ansible, Ceph
Isu takatora kubva kuSlurm misoro yakakosha pakushanda neKubernetes, asi haina hukama zvakananga nek8s. Sei, sei uye chii chakaitika - pasi pekucheka.
Vese vatori vechikamu veSlurm 4 vachawana mukana kune aya makosi.
Mari yakazara pazuva rekutanga
PaSt. Petersburg Slurm, vatori vechikamu vaviri vakaenda . Ndakademba sei kuti zvaisaita kuti ndidzoke nguva yakare tigoparadzana navo pasina kutaurirana.
Kana iwe ukaona zvausingade zvachose nezveSlurm, zuva rekutanga nyorera chero wevarongi. Tichadzima kuwana uye kudzosera mutengo wakazara wekutora chikamu.
Technical consultants
Kana paine anoziva (akaumba kirabhu yevatungamiriri vehunyanzvi), takamukoka kuSlurm (kuti adzidze, kwete kuita). Akavimbisa kupa munhu wese zano. Izvi hazvigone kuve zvekufarira kune vatariri nevagadziri, asi zvichave zvinonakidza kune mamaneja eIT.
Chii chinonzi Slurm
Slurm-4: kosi yekutanga (Chivabvu 27-29)
Yakagadzirirwa avo vanoona Kubernetes kekutanga kana vanoda kuronga ruzivo rwavo.
Mumwe nemumwe anotora chikamu achagadzira yavo sumbu muSelectel gore uye voisa application ipapo.

History tour
Yekutanga Slurm yaive kuyedza. Vakurukuri vakapedza mharidzo dzavo chaidzo pachikuva, uye muvateereri maigara vatariri venhanho zvokuti yakanga yava nguva yokuvakoka sevakurukuri.
Kosi chaiyo yakakosha yakaitika paSlurm yechipiri: 80% yevatori vechikamu vakaona Kubernetes kekutanga, uye chetatu akange asati amboshanda naDocker.
Zvaive pachena kuti zvaive zvakaoma sei kuti vanhu vateerere hurukuro paDocker mangwanani uye vashande nayo mukurwisa mode manheru.
Ceph yakakonzera matambudziko mazhinji. Uyezve, pakanga paine vanhu makumi maviri muvateereri vaifanira kunyatsotsanangura Ceph, uye vamwe makumi matanhatu vaisada Ceph zvachose.
Kune yechitatu Slurm, takafambisa Docker uye Ansible mumawebhusaiti akasiyana, tichisunungura imwe nguva yeKubernetes. Mhinduro yakazova inoshanda muchokwadi uye isina kuvandudzwa mukuita: hurukuro yacho yakanga isingafadzi kune vakomana vane ruzivo, uye nhaurirano yacho yakanga isingafadzi kune vanotanga.
Kune yechina Slurm, takaita online makosi paDocker, Ansible uye Ceph. Pfungwa yacho iri nyore: avo vanoida vanozotora kosi vachifunga, avo vasingaide vanoifuratira vakanyarara. Tichitonga neboka revanoedza, kosi yeDocker inotora maawa matanhatu-6. Ansible naCeph havasati vavhara.
Disiki:
- experimental course. Zvimwe zvisarudzo zvingava zvisina kubudirira.
- puratifomu (Stepik.org) haina kunaka, uye isu hatina kumboshanda nayo kare. Panogona kunge pave nemapundu uye snags.
- Kosi yacho yakaedzwa chete kuvashandi veSouthbridge. Chokwadi uchafanira kupedza chimwe chinhu sezvaunoenda.
Rimwe zuva mukutaura kwekutanga Slurm vakarangarira kutonhorera uye kunakidza kwazvaive, kunyangwe zvese zvaityisa musangano. Yekutanga kuwana zvinonyatsojeka zvinoonekwa. Ngationei zvinoitika kuvadzidzi vekutanga ve online makosi. 🙂
