Yintoni iShell enomda kwaye kutheni kubalulekile ukuhlasela iShell etsibayo
Iigobolondo ezithintelweyo zisetyenziselwa ukulawula imiyalelo abasebenzisi abanokuyenza, zihlala zithintela izenzo ezinje cd, ukuqalisa iigobolondo ezintsha, okanye ukuthumela ngaphandle izinto eziguquguqukayo zendalo. Zihlala zisetyenziswa kwi CI/CD iiarhente okanye ukwakha iindawo zokunciphisa indlela abasebenzisi abaziphethe ngayo. Nangona kunjalo, abahlaseli bafuna iindlela zokwenza iqokobhe lokutsiba, indlela esetyenziselwa ukubaleka kwiindawo ezithintelweyo zeqokobhe baze bafumane ukufikelela kwiiqokobhe ezingathintelwayo ezifana umgqomo/bash. Kanye ngaphakathi it, umhlaseli unolawulo olupheleleyo lomgca womyalelo, edlula yonke imida yendawo ethintelweyo.
Indlela i-Jumping Shell esebenza ngayo: Ukusuka kwi-Restricted ukuya kwi-bin/bash
Injongo yeqokobhe elitsibayo kukusebenzisa ubuthathaka kwiindawo ezithintelweyo kunye nokubangela ukuba iqokobhe liphume elikhokelela ekubeni umgqomo/bashIindlela eziqhelekileyo zokuhlasela iigobolondo ezithintelweyo zokubaleka ziquka:
$ ls /bin/bash $ /bin/bashIf umgqomo/bash iyafikeleleka, olu bizo lulula luyayigqibezela.
Enye indlela eqhelekileyo:
$ echo "/bin/bash" > run.sh $ sh run.sh Abahlaseli banokuxhaphaza abahleli abafana vi or Ngaphantsi:
vi :set shell=/bin/bash :shell Ezi ndlela zibonisa indlela ekulula ngayo ukutsiba iqokobhe umgqomo/bash ukuphunyezwa, ngokusebenzayo ukudlula ukhuseleko oluthintelweyo lweqokobhe.
Iingozi Zokwenyani Zale Nhlaselo kwiDevOps
Kwabelwana ngako CI/CD iindawo ezingqongileyo, iigobolondo ezithintelweyo zisetyenziselwa ukwahlukanisa ukwakhiwa kunye nokunciphisa umngcipheko. Kodwa xa umhlaseli ephumelela ngegobolondo elitsibayo aze afikelele umgqomo/bash, imodeli yokhuseleko iyawa.
Imingcipheko ibandakanya:
- Ukufikelela okungagunyaziswanga kwiimfihlo zendalo esingqongileyo
- Ukunyuka kwamalungelo ngaphandle kwemida umgqomo/bash
- Ukuphazamisana nokwakha pipelineokanye izinto zakudala
- Ukusasazwa kwezixhobo eziqhubekayo ngaphakathi pipeline
Iqokobhe elithintela ukubaleka umgqomo/bash ivula ucango oluya kwisivumelwano esipheleleyo senkqubo, idla ngokuba yinyathelo lokuqala ngokubanzi Uhlaselo lweDevSecOps.
Ukubeka esweni kunye nokubona ukutsiba kweShell kunye neBin/Bash
Ukuze kubonwe indlela eziqhuba ngayo iigobolondo ezitsibayo kunye nemizamo yokuthintela ukuphunyuka kweegobolondo, amaqela okhuseleko kufuneka:
- Bhala yonke imisebenzi yegobolondo, ngakumbi / ibin / ibash kuqhutywa
- Jonga ukusetyenziswa gwenxa komhleli kunye nokusetyenziswa kwesikripthi njengeevekhtha ze-shell spawn
- Landelela ukufikelela kwiifayile zoqwalaselo lweqokobhe ezifana .ukuku or .bash_profayile
Iipateni zokuziphatha ezifana nokuqalisa umgqomo/bash ukusuka kwindawo ethintelweyo kufuneka kuthathwe njengezilumkiso eziphambili. Ukuyifumana kwangethuba kunokuthintela intshukumo enzulu ecaleni.
Ukuthintela Ukubaleka Uhlaselo Olukhawulelweyo LweeShell kunye Nokuxhatshazwa
Ukunciphisa iingozi zokutsiba iimbumbulu kunye nokuthintela abahlaseli ekuqhumeni umgqomo/bash:
- Qinisa amaqokobhe athintelweyo: Susa okanye uvale ukufikelela
- Sebenzisa i-AppArmor okanye i-SELinux ukuthintela ukuphunyezwa komyalelo
- Sebenzisa amalungelo amancinci kuwo onke CI/CD iindima kunye nabagijimi
- I-Containerize yakha ngemifanekiso engenazo iigobolondo ezifana umgqomo/bash
- Qinisekisa iindawo ngaphambi nasemva kokwakhiwa ukuze ubambe izinto ezingaqhelekanga
Ukuthintela iimeko zegobolondo ezithintelweyo zokubaleka kufuna ulawulo olunemigangatho, kungekuphela nje ukuxhomekeka kwiigobolondo ezithintelweyo. Musa ukucinga ukuba iigobolondo ezithintelweyo zikhuselekile ukuba umgqomo/bash inokufikeleleka.
Isiphelo: Ukubaleka kweShell ngamanqaku okungena
Iimbumbulu ezithintelweyo zingumaleko wokhuselo, azisisiqinisekiso. Uhlaselo lweembumbulu ezitsibayo lujolise ekuzihlukaniseni okubuthathaka kunye nokuqinisekiswa okungekho ngqiqweni. Nje ukuba zingene ngaphakathi / ibin / ibash, abahlaseli banokujika, baqhubeke, kwaye babeke emngciphekweni iziseko zeDevSecOps.
Ukuchonga kunye nokwahlukanisa kubalulekile. Ukudibanisa ukuloga imiyalelo, iindawo ezithintelweyo, kunye nokucocwa ngokufanelekileyo kwabaphathi beepakeji kunciphisa ukuvezwa.
Okokugqibela, izixhobo ezifana I-Xygeni zibonelela ngokubonakala kwezi ngozi. Zinceda ekuqinisekiseni ukuthembeka kwekhowudi, zibone indlela engaqhelekanga yokuziphatha kwegobolondo, kwaye khusela eyakho pipelinekwiingozi zangaphakathi nezangaphandle, kuquka ezo ziqala ngeqokobhe elilula lokutsiba ukuya / ibin / ibash okanye iinzame zokubaleka kwiindawo ezithintelweyo zeshelufu.
