Kutshanje, iindaba bezipapashiwe ukuba iSayithiGround, yenye yezona zinto zibalulekileyo zokubamba iwebhu eYurophu, zahlala kwilizwe lethu kwaye zamkela itekhnoloji yokusika ngokubhekisele kwintsebenzo: sithetha ngayo Izikhongozeli zeLinux okanye i-LXC. Lo msebenzi awukho mtsha, ngaphakathi kweenkqubo zokusebenza, kuba iFreeBSD ineeJele, iSolaris ineZones kwaye kukho ezinye iintlobo zezikhongozeli ezinje ngezo zinikezwe yi-OpenVZ kunye neLinux VServer ezinolungelelwaniso olwahlukileyo ngaphakathi kernel yazo ukuyenza.
Inyani yokuba iSayithiGound isamkele esi sikhundla ngokweetekhnoloji yayo, kunye nembono yayo ecacileyo yeshishini egxile ekusebenzeni okuphezulu kweziseko zophuhliso, kokubini kwinqanaba lehardware (ngokusebenzisa imeko eqinileyo iqhuba i-SSD) njengesoftware, iphakamisa umbuzo wokuba ilungile kwaye ithembisa. Sithetha malunga ne-LXC kwizikhongozeli ezingezantsi.
I-LXC okanye iiLinux Containers ngoku zimele enye yeetekhnoloji zangoku kunye noqikelelo olukhulu lwexesha elizayo. Imalunga ne Izikhongozeli ezenza ubume bemo yokusebenza kwinqanaba le-Linux kwaye zinokusasazwa kumatyeli amaninzi kwiseva efanayo yomzimba. Zonke zisebenza zodwa njengee-SPVs (i-Virtual Private Servers) okanye ii-EVs (Virtual Environments), apho zonke izibonelelo zibonelelwa kulungelelwaniso, unxibelelwano kunye nenqanaba lokugcina.
Kodwa luphi uncedo lweziqulathi ngenene? Masithathe lo mzekelo ulandelayo. Indawo yokungena yenkonzo ifuna ukuba abasebenzisi bayo bakwazi ukuhambisa amaqonga azimeleyo kunye nodwa kwimfuno. Ngokwesiko, yonke isoftware kunye nezinto eziyimfuneko kwisixhobo ngasinye esifunekayo kuya kufuneka sifakelwe, kodwa enkosi kwizikhongozeli, Zonke izibonelelo eziyimfuneko zinokudityaniswa kwaye zidityaniswe amaxesha amaninzi njengoko kufuneka ngokuzenzekelayo.
Xa bekuSayithiGound benze imfuduko yabo yokugqibela abayamkeleyo, ukongeza kule teknoloji, ukugcinwa kwidiski ye-SSD yesimo esomeleleyo. I-LXC ibabonelela, ngamagama abasebenzi bayo, ukuguquguquka okufunekayo kwishishini lakho, kunye nee disks zeSSD isantya sokwenza kufuneka ukubonelela ngenkonzo eyoneleyo ngexesha kubasebenzisi bayo. Ukongeza, inkampani yenze ukuphunyezwa kwayo kwe-LXC kwaye ivelise uninzi lweepatches zeLinux kernel elungisa iibugs kunye nokulungisa iingxaki zokhuseleko.
Ikamva lezikhongozeli lijongeka lithembisa kakhulu kwaye linokupela ukuphela kobuchule njengoko siyazi namhlanje. Okanye hayi?
Iimpawu zeLXC
La Ukubanakho ukwenza izikhongozeli ezifakwe ngaphakathi nezikwanti ngequla lakho lezixhobo ngumsebenzi osele wenziwe namhlanje ngokubonakalayo kwimeko-bume. Nangona kunjalo, itekhnoloji yeekhonteyina ibonelela ngokwanda kokusebenza (phantse kufana nokungabonakali kwesinyithi) kunye nokuguquguquka. Izikhongozeli azilingisi izixhobo zomatshini kwaye ukuba nje indawo ayiboniswanga, akukho sithuba sokugcina sithathiweyo.
I-LXC kufuneka ikhulelwe njenge inkqubo yokusebenza ngaphakathi kweyethu, kwaye ngenxa yeenjongo ezibonakalayo iziphatha njengomatshini obonakalayo. Ukulinganisa kwenziwa nge-Linux kernel uqobo kwaye i-LXC ibonelela ngesiqulatho esincinci ukuze ikwazi ukugcina itemplate yokuhanjiswa kweenkqubo ezahlukeneyo kunye nokusetyenziswa komsebenzisi okuvumela ukusetyenziswa kwayo kwakhona kwiindawo ezahlukeneyo kunye nemijikelezo yophuhliso.
La ukuthwala Ngalo msebenzi uyaqinisekiswa, kuba iyasusa usetyenziso kwinkqubo yokusebenza kwaye kunokwenzeka ukuba usebenze nasiphi na isikhongozeli kufakelo lwendalo encinci. Ukongeza, ngenxa yokwahlulwa kwezixhobo, kunokwenzeka ukuba usebenzise iimeko ezininzi zeenguqulelo ezininzi zeJava, i-PHP okanye i-Apache ngaxeshanye, kunye nokuguquguquka okupheleleyo kunye nokukwazi ukulinganisa imithwalo yabo phakathi kweenkqubo ezininzi, ukuhambelana nemo engqongileyo okanye ukwenza ukhuphelo lwakutshanje kumcimbi wemizuzwana.
Ikamva lokwenziwa kwezinto alikagqitywa, kuba ngayo kunokwenzeka ukuhambisa izinto ezahlukeneyo zendalo, okwangoku, izikhongozeli azikwazi ukusebenzisa i-kernel ethile kulo msebenzi.
I-LXC kunye ne-Docker
I-LXC kunye ne-Docker ziinkqubo ezimbini zokuthwala ezisebenzisa ifilosofi ngendlela efanayo: Yenza ubume bodwa kwindawo ezahlukeneyo zesicelo ezisebenza ngokuzimela. Ubutu usebenza ngazo zombini ezi projekthi oko kuhlala kuthanda ukubhideka kwaye umahluko ophambili esikwenzayo uqaphele. Izikhongozeli I-LXC ine-init evumela ukuba kuphunyezwe iinkqubo ezininzi ngelixa Izikhongozeli zeDocker zinokuqhuba kuphela inkqubo enye yohlobo ngalunye.
Umbono weDocker ukunciphisa ubungakanani beekhonteyina zakho kangangoko kunokwenzeka kwinkqubo enye elawulwa kwesi sicelo. Ingxaki kukuba uninzi lwezicelo eziphuhlisiweyo namhlanje zinolindelo lokukwazi ukwenziwa kwiindawo ezifundwayo, ngenkxaso yeekron ezininzi, iidemem, ii-SSH, njl. Kuba iDocker ayinayo nayiphi na kwezi, ukumiliselwa kwemeko yokusasazwa, inethiwekhi, ukugcinwa kunye nokucwangciswa kokugqibela kwenkqubo yonke kufuneka kwenziwe ngesicelo.
Le yincam yomkhenkce, njenge Eminye imibuzo isemoyeni ezinje ngolawulo lwezixhobo zenethiwekhi, ukuthungelwa konxibelelwano, ingqokelela yeekhonteyina okanye ukufuduka phakathi kweendawo ezishushu. Okwangoku, kubonakala ngathi umsantsa owahlula bobabini ubuchwephesha ufuna ukuncitshiswa kwaye iya kuba lixesha lokuthatha isigqibo sokuba yeyiphi iteknoloji eya kubekwa apha ngasentla.
