Kutsitsa Kutsitsa mu Openstack

M'makina akuluakulu amtambo, vuto la kusanja kapena kusanja katundu pamakompyuta ndizovuta kwambiri. Tionix (wokonza ndi wogwiritsa ntchito mautumiki amtambo, mbali ya gulu la makampani a Rostelecom) nayenso wasamalira nkhaniyi.

Ndipo, popeza nsanja yathu yayikulu yachitukuko ndi Openstack, ndipo ife, monga anthu onse, ndi aulesi, adaganiza zosankha gawo lokonzekera lomwe laphatikizidwa kale papulatifomu. Chosankha chathu chinagwera pa Watcher, yomwe tinasankha kugwiritsa ntchito zosowa zathu.

Choyamba, tiyeni tione mawu ndi matanthauzo.

Migwirizano ndi Matanthauzo

Cholinga ndi zotsatira zowerengeka, zowoneka komanso zoyezeka zomwe ziyenera kukwaniritsidwa. Pali njira imodzi kapena zingapo zokwaniritsira cholinga chilichonse. Njira ndi kukhazikitsidwa kwa algorithm yomwe imatha kupeza yankho la cholinga choperekedwa.

Zochita ndi ntchito yoyambira yomwe imasintha momwe zinthu ziliri pagulu la OpenStack, monga: kusamutsa makina enieni (kusamuka), kusintha mphamvu ya node (change_node_power_state), kusintha mawonekedwe a nova service (change_nova_service_state). ), kusintha kukoma (kusintha), kulembetsa mauthenga a NOP (nop), kusachitapo kanthu kwa nthawi yayitali - kupuma (kugona), disk transfer (volume_migrate).

Zochita - kuyenda kwinakwake kwa zochita zomwe zimachitika mwadongosolo linalake kuti mukwaniritse cholinga china. Dongosolo la Ntchito lilinso ndi machitidwe oyezera padziko lonse lapansi okhala ndi zizindikiro za magwiridwe antchito. Dongosolo la ntchito limapangidwa ndi Woyang'anira pa kafukufuku wopambana, chifukwa chake njira yomwe idagwiritsidwa ntchito imapeza yankho kuti akwaniritse cholingacho. Dongosolo la zochita limakhala ndi mndandanda wa zochita motsatizana.

Audit ndi pempho kukhathamiritsa cluster. Kukhathamiritsa kumachitika kuti mukwaniritse Cholinga chimodzi pagulu lopatsidwa. Pakuwunika kulikonse kopambana, Watcher imapanga Dongosolo Lochita.

Audit Scope ndi gulu lazinthu zomwe kafukufukuyu amachitira (malo opezeka), ma node aggregators, ma compute node kapena malo osungira, etc.). Kuchuluka kwa kafukufuku kumafotokozedwa mu template iliyonse. Ngati chiwerengero cha kafukufuku sichinatchulidwe, gulu lonse limawerengedwa.

Audit template - makonda osungidwa kuti ayambitse kafukufuku. Ma templates amafunikira kuti mufufuze kangapo ndi makonda omwewo. Tsambali liyenera kukhala ndi cholinga cha kafukufukuyu; ngati njira sizinatchulidwe, ndiye kuti njira zomwe zilipo ndizosankhidwa.

Gulu ndi gulu la makina akuthupi omwe amapereka makompyuta, kusungirako, ndi maukonde zothandizira ndipo amayendetsedwa ndi njira yomweyo yoyang'anira OpenStack.

Cluster Data Model (CDM) ndi chifaniziro chomveka cha momwe zinthu zilili panopa komanso topology ya zinthu zomwe zimayendetsedwa ndi gululo.

Chizindikiro Chogwira Ntchito - chizindikiro chomwe chimasonyeza momwe yankho lopangidwira pogwiritsa ntchito njirayi likuchitikira. Zizindikiro za kagwiridwe ka ntchito zimakhala zachindunji ku cholinga chinachake ndipo nthawi zambiri zimagwiritsidwa ntchito powerengera mphamvu yapadziko lonse ya ndondomeko yotsatilapo.

Kufotokozera Mwachangu ndi mndandanda wazinthu zapadera zomwe zimagwirizanitsidwa ndi Cholinga chilichonse chomwe chimatanthauzira zizindikiro zosiyanasiyana zogwirira ntchito zomwe njira yokwaniritsira Cholinga choyenera iyenera kukwaniritsa mu yankho lake. Zowonadi, yankho lililonse lomwe laperekedwa ndi njirayo lidzawunikidwa molingana ndi zomwe zafotokozedwera musanawerengere momwe imathandizira padziko lonse lapansi.

Scoring Engine ndi fayilo yomwe ingagwiritsidwe ntchito yomwe ili ndi zolowa zodziwika bwino, zotuluka zodziwika bwino, ndipo imagwira ntchito yamasamu. Mwanjira iyi, kuwerengerako sikudalira chilengedwe komwe kumachitikira - kudzapereka zotsatira zomwezo kulikonse.

Woyang'anira Planner - gawo la injini yopangira zisankho za Woyang'anira. Gawoli limatenga zochitika zomwe zimapangidwa ndi njira ndikupanga dongosolo la kayendetsedwe ka ntchito lomwe limafotokozera momwe mungakonzekere zochitika zosiyanasiyanazi munthawi yake komanso pachinthu chilichonse, zomwe ziyenera kukhala.
