Akuyona imfihlo ukuthi ngezilungiselelo ezizenzakalelayo I-Ansible ayikwazi ukwenza umsebenzi wayo ngokushesha okukhulu. Esihlokweni ngizoveza izizathu ezimbalwa zalokhu futhi nginikeze ubuncane bezilungiselelo eziwusizo, okungenzeka, empeleni zikhulise isivinini sephrojekthi yakho.
Lapha nangezansi sixoxa nge-Ansible 2.9.x, efakwe ku-virtualenv esanda kwakhiwa ngendlela oyithandayo.
Ngemva kokufaka, dala ifayela elithi “ansible.cfg” eduze kwebhuku lakho lokudlala - le ndawo izokuvumela ukuthi udlulise lezi zilungiselelo kanye nephrojekthi, futhi zizolayisha ngokuzenzakalelayo.
Ukufakwa kwamapayipi
Abanye kungenzeka ukuthi sebezwile kakade ngesidingo sokusebenzisa amapayipi, okungukuthi, ukungakopishi amamojula ohlelweni lwefayela lesistimu eqondiwe, kodwa ukudlulisa ingobo yomlando ye-zip esongwe ku-Base64 ngqo ku-stdin yomhumushi wePython, kodwa abanye bangase bangenzi, kodwa iqiniso. kuhlala kuyiqiniso: kusathathwa kancane. Ngeshwa, okunye okusatshalaliswa kweLinux okudumile okusetshenziselwa ukulungisa i-sudo kahle ngokuzenzakalelayo - ukuze lo myalo udinga i-tty (itheminali), ngakho-ke i-Ansible ishiye lesi silungiselelo esiwusizo kakhulu sikhutshazwe ngokuzenzakalelayo.
pipelining = TrueUkuqoqa amaqiniso
Ingabe bewazi ukuthi ngezilungiselelo ezizenzakalelayo, Ukufaneleka kokudlala ngakunye kuqalisa iqoqo lamaqiniso labo bonke ababungazi ababamba iqhaza kukho? Ngokuvamile, uma ubungazi, manje uyazi. Ukuze uvimbele lokhu ukuthi kungenzeki, udinga ukunika amandla imodi yokucela esobala yokuqoqa amaqiniso (okusobala) noma imodi ehlakaniphile. Kuyo, amaqiniso azoqoqwa kuphela kulabo basokhaya abangazange bahlangane nemidlalo edlule.
I-UPD. Lapho ukopisha, kuzodingeka ukhethe eyodwa yalezi zilungiselelo.
gathering = smart|explicitUkusebenzisa kabusha ukuxhumana kwe-ssh
Uma uke wasebenzisa i-Ansible kwimodi yokulungisa iphutha (inketho ethi "v", ephindaphindwa izikhathi eziyisishiyagalolunye kuya kweziyisishiyagalolunye), kungenzeka ukuthi uqaphele ukuthi ukuxhumana kwe-ssh kwenziwa njalo futhi kuphulwa. Ngakho, kukhona ezimbalwa ezicashile lapha futhi.
Ungakwazi ukugwema isinyathelo sokuphinda usungule uxhumano lwe-ssh kumaleveli amabili ngesikhathi esisodwa: kokubili ngokuqondile kuklayenti le-ssh, nalapho udlulisela amafayela kumsingathi ophethwe esuka kumphathi.
Ukusebenzisa kabusha uxhumano lwe-ssh oluvulekile, vele udlulise okhiye abadingekayo kuklayenti le-ssh. Ngemuva kwalokho izoqala ukwenza lokhu okulandelayo: lapho isungula uxhumano lwe-ssh okokuqala ngqa, izophinde idale okuthiwa isokhethi lokulawula, ekufakweni okulandelayo, izohlola ukuba khona kwalesi sokhethi, futhi uma iphumelele, sebenzisa kabusha uxhumano lwe-ssh olukhona. Futhi ukwenza konke lokhu kube nengqondo, ake sibeke isikhathi sokugcina ukuxhumana lapho kungasebenzi. Ungafunda kabanzi ku , futhi kumongo we-Ansible simane sisebenzisa "ukudlulisela" izinketho ezidingekayo kuklayenti le-ssh.
ssh_args = "-o ControlMaster=auto -o ControlPersist=15m"Ukuze usebenzise kabusha uxhumano lwe-ssh oseluvele luvuliwe lapho udlulisela amafayela kumsingathi ophethwe, vele ucacise esinye isilungiselelo esingaziwa ssh_tranfer_method. Imibhalo ephathelene nalesi sihloko ibaluleke kakhulu futhi iyadukisa, ngoba le nketho isebenza kahle! Kodwa ukufunda ikuvumela ukuthi uqonde ukuthi kuzokwenzekani ngempela: umyalo we-dd uzokwethulwa kumsingathi ophethwe, usebenza ngqo nefayela olifunayo.
transfer_method = pipedNgendlela, egatsheni elithi "thuthukisa" lesi silungiselelo sikhona .
Ungawusabi ummese, usabe imfologo
Esinye isilungiselelo esiwusizo izimfoloko. Inquma inani lezinqubo zabasebenzi ezizoxhumeka ngesikhathi esisodwa kubasingathi futhi zenze imisebenzi. Ngenxa yezici zePython njengolimi, kusetshenziswa izinqubo, hhayi imicu, ngoba i-Ansible isasekela iPython 2.7 - ayikho i-asyncio yakho, asikho isidingo sokwethula ukuziphatha okuvumelanayo lapha! Ngokuzenzakalelayo imigijimo ye-Ansible abasebenzi, kodwa uma ibuzwa kahle, izokwethula okwengeziwe:
forks = 20Ngivele ngikuxwayise ngokushesha ukuthi kungase kube khona ubunzima lapha obuhlobene nenani elitholakalayo lememori emshinini wokulawula. Ngamanye amazwi, ungabeka izimfoloko=100500, kodwa ngubani othe kuzosebenza?
Ukuhlanganisa konke
Njengomphumela, ku-ansible.cfg (ifomethi ye-ini), izilungiselelo ezidingekayo zingabukeka kanje:
[defaults]
gathering = smart|explicit
forks = 20
[ssh_connection]
pipelining = True
ssh_args = -o ControlMaster=auto -o ControlPersist=15m
transfer_method = piped
Futhi uma ufuna ukufihla yonke into ku-YaML-inventory evamile yomuntu onempilo, khona-ke ingabukeka kanje:
---
all:
vars:
ansible_ssh_pipelining: true
ansible_ssh_transfer_method: piped
ansible_ssh_args: -o ControlMaster=auto -o ControlPersist=15m
Ngeshwa, lokhu ngeke kusebenze nezilungiselelo ezithi “gathering = smart/explicit” kanye “nezimfoloko = 20”: okufana kwazo ne-YaML akukho. Kuphakathi kokuthi siwasetha kokuthi ansible.cfg, noma siwadlulisela ezintweni eziguquguqukayo zemvelo ANSIBLE_GATHERING kanye ne-ANSIBLE_FORKS.
Mayelana ne-Mitogen
- Kukuphi lokhu mayelana neMitogen? - unelungelo lokubuza, mfundi othandekayo. Akukho ndawo kulesi sihloko. Kodwa uma usukulungele ngempela ukufunda ikhodi yayo futhi uthole ukuthi kungani i-playbook yakho iphahlazeka ne-Mitogen, kodwa isebenza kahle nge-vanilla Ansible, noma kungani i-playbook efanayo yayisebenza kahle ngaphambili, kodwa ngemva kokubuyekezwa kwaqala ukwenza izinto ezingavamile - kahle, uMitogen. kungenzeka kube yithuluzi lakho . Yisebenzise, iqonde, bhala izindatshana - ngizoyifunda ngentshisekelo.
Kungani ngingasebenzisi iMitogen mathupha? Ngoba i-Gladiolus isebenza kuphela inqobo nje uma imisebenzi ilula futhi yonke into ihamba kahle. Kodwa-ke, uma ujikela kancane kwesokunxele noma kwesokudla - yilokho-ke, sesifikile: ngokuphendula, idlanzana lezinto ezihlukile ezingacacile zindizela kuwe, futhi ukuqedela isithombe, okushodayo nje inkulumo evamile "ngiyabonga nonke , wonke umuntu ukhululekile.” Ngokuvamile, angifuni nje ukuchitha isikhathi ngithola izizathu zokulandelayo "zokushaya ngaphansi komhlaba".
Ezinye zalezi zilungiselelo zitholwe phakathi nenqubo yokufunda i-plugin yokuxhumana ngaphansi kwegama elizichazayo elithi "ssh.py". Ngihlanganyela imiphumela yokufunda ngethemba lokuthi kuzogqugquzela omunye umuntu ukuthi abheke imithombo, ayifunde, ahlole ukuqaliswa, aqhathanise nemibhalo - emva kwakho konke, ngokushesha noma kamuva konke lokhu kuzokulethela imiphumela emihle. Ngikufisela inhlanhla!
Abasebenzisi ababhalisiwe kuphela abangabamba iqhaza kuhlolovo. , wamukelekile.
