Chelete ea morao-rao e sa hlokahaleng ea letsatsi la pele ("Haeba u ikutloa hore Slurm ha ea u tšoanela, re tla busetsa theko e feletseng ea tekete") e ne e sebelisoa ke motho a le mong feela, ho lokafatsa hore o feteletse matla a hae.
- Slurm e latelang e tla etsahala mathoasong a September St. Petersburg. Selectel, motšehetsi oa rona oa ka ho sa feleng, ha a fane ka leru feela bakeng sa litulo, empa hape le kamore ea eona ea likopano.
- Re pheta Slurm ea mantlha (Lwetse 9-11) mme re hlahisa lenaneo le lecha: DevOps Slurm (La 4-6 Loetse).
Slurm ke eng mme e fetohile joang?
Selemong se fetileng, re ile ra tla ka mohopolo oa ho etsa lithuto ho Kubernetes. Ka Phato '18, Slurm-1 e ile ea etsahala: ho thata, ka tlhahiso e tsoelang pele (ha nehelano e felile sethaleng), ka bongata ba mathata a letsatsi le letsatsi. Liteko lia kopanya: barupeluoa ba Slurm ea pele, joalo ka Fellowship of the Ring, ba ntse ba buisana.
Sena ke kamoo Slurm-1 e neng e shebahala kateng
Ho Slurm ea pele, mohopolo oa ho ts'oara MegaSlurm o ile oa hlaha. Re ile ra botsa batho hore na ba thahasella lihlooho life, ’me ka October re ile ra tšoara thupelo e tsoetseng pele “Ka kōpo ea barupeluoa.” E ile ea e-ba ketsahalo e thahasellisang, empa ea nako e le 'ngoe. Ka May '19 re se re hlophisitse thupelo e tsoetseng pele, e nang le mabaka a eona le nalane ea eona ea kahare.
Ha selemo se ntse se feta, Slurm e fetohile mokhatlong:
- Docker le Anisble ba ile ba tlosoa lenaneong la mantlha mme ba etsoa lithuto tse arohaneng tsa inthanete.
- Tšehetso e hlophisitsoeng ea tekheniki e thusang baithuti ho rarolla lihlopha tsa ho ithuta.
- Hona joale libui li na le tšehetso ea mokhoa.

Maikutlo a tsoang ho barupeluoa
Rekoto e 'ngoe e ile ea beoa: barupeluoa ba 170 ho Slurm ea mantlha, ba 75 ho MegaSlurm.
Slurm-4
Batho ba 101 ho ba 170 ba tlatsitse foromo ea maikutlo.
Na Kubernetes e hlakile?

U rata matla a Slurm joang?
Batho ba 16 ba nahana hore Slurm e bonolo haholo ebile e lieha, mme batho ba 14 ba nahana hore e thata haholo ebile e potlakile. Hantle feela bakeng sa ba bang kaofela.
A na u rarolotse bothata boo u neng u il'o ho Slurm ka bona?
90 - ho joalo.
11 - Che.
MegaSlurm
Batho ba 40 ba ile ba tlatsa foromo ea maikutlo. Batho ba 2 ba itse ho bonolo ebile ho lieha. Motho a le mong ha a ka a rarolla bothata boo a neng a ea Mega ka bona. Tse ling kaofela li lokile.
Maikutlo a libui
Haeba St. Petersburg Slurm ka February ho ne ho e-na le ba qalang haholo, joale batho ba bangata ba Moscow Slurm ba ne ba se ba lekile Kubernetes. Ho ne ho e-na le lipotso tse ngata tse tsoetseng pele tse entseng hore u nahane.
Haeba St. Petersburg ba botsa hore na re tla phatlalatsa fereko ea rona ea kubespray neng, joale Moscow ba se ba ntse ba botsa hore na ke hobane'ng ha re etsa tlhahiso ea ho sebelisa fereko ea rona eseng ho nka kubespray ea pele. Ena e se e ntse e le monahano oa bohlokoa oa batho ba baholo ba bohareng.
Tloaelo e ne e le thata, batho ba entse liphoso tse ngata, 'me ke ntho e ntle: ho hlokahala hore u etse liphoso ha u ntse u ithuta, eseng ntoeng.
Re ne re lula re kopana le meeli ea ho fumana litifikeiti, meeli ea ho khoasolla ho tsoa ho Github, jj. Bona ke bophelo - ka nako e le 'ngoe re tsamaisitse lihlopha tse ka bang 200 lerung la Selectel. Ha ho motho ea lokisang lisebelisoa le meeli ea bona bakeng sa sena.
