Infrastructure li bash keeb kwm

Qhov kuv kawm tau los ntawm Kev Xeem 200 Kab ntawm Infrastructure Code

Piv txwv tias koj tuaj rau qhov project tshiab, thiab lawv hais rau koj: β€œpeb muaj Infrastructure li Code". Hauv kev muaj tiag nws hloov tawm Infrastructure li bash keeb kwm los yog piv txwv Cov ntaub ntawv raws li keeb kwm bash. Qhov no yog qhov xwm txheej tiag tiag, piv txwv li, ib qho xwm txheej zoo sib xws tau piav qhia los ntawm Denis Lysenko hauv kev hais lus Yuav ua li cas hloov tag nrho cov infrastructure thiab pib pw tsaug zog, nws hais li cas lawv tau txais kev sib koom ua ke rau qhov project los ntawm keeb kwm bash.

Nrog qee qhov kev ntshaw, peb tuaj yeem hais qhov ntawd Infrastructure li bash keeb kwm qhov no yog li code:

  1. kev yug dua tshiab: Koj tuaj yeem nqa keeb kwm bash, khiav cov lus txib los ntawm qhov ntawd, thiab koj tuaj yeem, los ntawm txoj kev, tau txais kev teeb tsa ua haujlwm raws li qhov tso tawm.
  2. versioning: koj paub leej twg tuaj thiab lawv tau ua dab tsi, dua, nws tsis yog qhov tseeb tias qhov no yuav coj koj mus rau kev teeb tsa ua haujlwm ntawm qhov tawm.
  3. keeb kwm: zaj dab neeg ntawm leej twg ua dab tsi. tsuas yog koj yuav tsis tuaj yeem siv nws yog tias koj poob lub server.

Kuv yuav ua li cas?

Infrastructure li Code

Qhov kuv kawm tau los ntawm Kev Xeem 200 Kab ntawm Infrastructure Code

Txawm li cas los txawv txawv li Infrastructure li bash keeb kwm koj tuaj yeem rub nws los ntawm pob ntseg Infrastructure li Code, tab sis thaum peb xav ua ib yam dab tsi nyuaj dua li qhov zoo qub LAMP server, peb yuav los xaus tias cov cai no yuav tsum tau hloov kho, hloov pauv, txhim kho. Tom ntej no peb xav xav txog cov parallels ntawm Infrastructure li Code thiab kev txhim kho software.

DRY

Qhov kuv kawm tau los ntawm Kev Xeem 200 Kab ntawm Infrastructure Code

Ntawm qhov kev tsim kho qhov system cia, muaj ib qho haujlwm ua haujlwm ib ntus configure SDS: peb tab tom tso tawm tshiab - nws yuav tsum tau muab dov tawm rau kev sim ntxiv. Txoj haujlwm yog qhov yooj yim heev:

  • nkag rau hauv no ntawm ssh thiab ua tiav cov lus txib.
  • luam cov ntaub ntawv ntawd.
  • kho qhov config ntawm no.
  • pib qhov kev pabcuam ntawd
  • ...
  • TSWV YIM!

Rau cov lus piav qhia, bash yog ntau tshaj qhov txaus, tshwj xeeb tshaj yog nyob rau theem pib ntawm qhov project, thaum nws nyuam qhuav pib. Qhov no nws tsis phem uas koj siv bash, tab sis dhau sij hawm muaj kev thov kom xa tej yam zoo sib xws, tab sis txawv me ntsis. Thawj qhov uas los rau hauv siab yog luam-paste. Thiab tam sim no peb twb muaj ob tsab ntawv zoo sib xws uas yuav luag zoo ib yam. Sij hawm dhau mus, tus lej ntawm cov ntawv loj tuaj, thiab peb tau ntsib nrog qhov tseeb tias muaj qee yam kev lag luam logic rau kev siv lub installation uas yuav tsum tau synchronized ntawm cov ntawv sib txawv, qhov no yog qhov nyuaj heev.

Qhov kuv kawm tau los ntawm Kev Xeem 200 Kab ntawm Infrastructure Code

Nws hloov tawm tias muaj kev xyaum zoo li DRY (Tsis Txhob Rov Ua Koj Tus Kheej). Lub tswv yim yog rov siv cov cai uas twb muaj lawm. Nws suab yooj yim, tab sis peb tsis tuaj rau qhov no tam sim ntawd. Nyob rau hauv peb cov ntaub ntawv, nws yog ib lub tswv yim banal: cais configs los ntawm scripts. Cov. lag luam logic ntawm yuav ua li cas lub installation yog deployed nyias, configs nyias.

SOLID rau CFM

Qhov kuv kawm tau los ntawm Kev Xeem 200 Kab ntawm Infrastructure Code

Thaum lub sij hawm qhov project loj hlob thiab natural continuation yog qhov tshwm sim ntawm Ansible. Lub ntsiab yog vim li cas rau nws cov tsos yog hais tias muaj kev txawj ntse ntawm pab neeg thiab bash tsis yog tsim rau complex logic. Ansible kuj pib muaj cov logic nyuaj. Txhawm rau tiv thaiv tsis yooj yim logic los ntawm kev hloov mus rau hauv chaos, muaj cov hauv paus ntsiab lus rau kev teeb tsa cov cai hauv kev txhim kho software SOLID Tsis tas li ntawd, piv txwv li, Grigory Petrov hauv tsab ntawv tshaj tawm "Vim li cas tus kws tshaj lij IT xav tau lub npe ntawm tus kheej" tau tsa cov lus nug uas tus neeg tau tsim los ntawm txoj hauv kev uas nws yooj yim dua rau kev khiav lag luam nrog qee lub koom haum hauv zej zog, hauv kev txhim kho software. yog khoom. Yog tias peb muab ob lub tswv yim no thiab txuas ntxiv txhim kho lawv, peb yuav pom tias peb tuaj yeem siv tau SOLID ua kom yooj yim rau kev tswj hwm thiab hloov kho qhov kev xav no yav tom ntej.
