TL; DR
ichaitwa muMoscow muna Ndira 30 - Kukadzi 1.
Zvakare isu tichaongorora maturusi eDevOps mukuita.
Details uye purogiramu pasi pekucheka.
SRE yakabviswa purogiramu nokuti pamwe chete naIvan Kruglov tiri kugadzirira yakasiyana Slurm SRE. Chiziviso chichauya gare gare.
Kutenda kuna Selectel, vatsigiri vedu kubva kune yekutanga Slurm!
Nezvehuzivi, kusava nechokwadi uye kubudirira kusingatarisirwi
Ndakapinda DevOpsConf muMoscow pakupera kwaSeptember.
Pfupiso yezvandakanzwa:
-DevOps inodiwa nemapurojekiti mazhinji echero saizi;
- DevOps itsika, seyese tsika, inofanirwa kubva mukati mekambani. Iwe haugone kuhaya DevOps injinjini uye kurota kuti achavandudza maitiro.
-Pakupedzisira rondedzero yezvinodiwa kushanduko yeDevOps kunouya tekinoroji, kureva, iwo chaiwo maturusi eDevOps atinodzidzisa.
Ndakaona kuti takanga takarurama kuti tisabatanidze huzivi hweDevOps uye tsika muchikoro, nokuti izvi hazvigone kudzidziswa zvakarongeka. Ani nani anoida achaiverenga mumabhuku. Kana kuti achawana murairidzi anotonhorera anogonesa munhu wese necharisma yake uye chiremera.
Ini pachangu, ini ndagara ndiri mutsigiri we "kufamba kubva pasi", iyo guerrilla kushandiswa kwetsika kuburikidza nemidziyo. Chimwe chinhu chakafanana neicho chakatsanangurwa muThe Phoenix Project. Kana isu tiine mushandirapamwe neGit yakamisikidzwa nemazvo, tinogona zvishoma nezvishoma kuiwedzera nemirau, uye zvino inosvika kune zvakakosha.
Uye zvakafanana, patakanga tichigadzirira DevOps Slurm, patakanga tichingotaura nezve maturusi chete, ndaitya maitiro evatori vechikamu: "Wakataura zvinhu zvinoshamisa. Zvinosiririsa, handife ndakakwanisa kuzviita. β Pakanga pane kusava nechokwadi kwakawanda zvokuti takabva tangorega kudzokorora purogiramu yacho.
Nekudaro, ruzhinji rwevatori vechikamu vakapindura muongororo kuti ruzivo rwakawanikwa rwaishandiswa mukuita, uye kuti vaizoshandisa chimwe chinhu munyika yavo munguva pfupi iri kutevera. Panguva imwecheteyo, zvese zvatakatsanangura zvakaverengerwa murondedzero yezvinhu zvinobatsira: Git, Ansible, CI/CD, uye SRE.
Zvingave zvakakodzera kuyeuka kuti pakutanga vakataurawo nezveSlurm Kubernetes kuti hazvibviri kutsanangura k3s mumazuva matatu.
NaIvan Kruglov, uyo akatungamirira musoro weSRE, takabvumirana pane imwe purogiramu yakasiyana. Parizvino tirikukurukura nezvenyaya, ndichaita chiziviso munguva pfupi.
