La Ukubona sele kuyinto eqhelekileyongakumbi kwiinkonzo zelifu ukuze zikwazi ukufumana okuninzi kumaseva kumaziko edatha. Kodwa mva nje, ubonelelo olusekwe kwisikhongozeli yeyona nto inyanzeliswayo, kuba ivumela ulawulo olusebenza ngakumbi (ngokungafuneki ukuphinda-phinda iinkqubo ezithile). Kwaye kule nto iphakamileyo apho kuvela khona amadabi eDocker vs Kubernetes.
Iiprojekthi ezimbini ezidumileyo, osenokuba sele usazi. Zombini nge eziluncedo nezingeloncedo, kunye neyantlukwano enokuba yinto ephambili xa kufikwa ekuncedeni ukuba ukhethe iprojekthi ngokweemfuno zakho ...
Yintoni i-virtualization esekwe kwisikhongozeli?
Njengoko usazi, kukho ezininzi Iindidi zokwenza ubonelelonjengokujonga ngokupheleleyo, ukwenza paravirtualization, njl. Ewe, kweli candelo ndiza kugxila kubungqina obupheleleyo obuqhele ukusetyenziswa xa kusonyuswa oomatshini ababonakalayo, kunye nezikhongozeli, ukuze ungazisi ezinye izinto ezinokukuphazamisa.
- Oomatshini ababonakalayo-Yindlela efikelelekayo yokujonga ubuchule. Isekwe kwi-hypervisor, enje nge-KVM, i-Xen, okanye iinkqubo ezinje nge-VMWare, i-VirtualBox, njl. Ngale software, umatshini opheleleyo ophathekayo (vCPU, vRAM, idiski eqhuba, iinethiwekhi ezibonakalayo, iipheripherali, njl. Ke ngoko, inkqubo yokusebenza (undwendwe) inokufakwa kwezi zixhobo kwaye ukusukela apho, usetyenziso lunokufakwa kwaye luqhutywe ngendlela efanayo naleyo inokwenziwa ngayo kwinkqubo yokusebenza yomgcini.
- Izikhongozeli: Yenye itekhnoloji apho uhlobo lwendlwana okanye ibhokisi yesanti edityanisiweyo apho ezinye iinxalenye zale nkqubo ingagqitywa, esebenza ngakumbi kwaye inokubanakho ukuthwala kunye nezinye izibonelelo zokhuselo (nangona ingekho sengozini). Ngapha koko, endaweni yokuba ne-hypervisor, kwezi meko kukho isoftware efana neDocker kunye neKubernetes eziza kusebenzisa inkqubo yokubamba ngokwayo ukuqhuba ii -apps ezizimeleyo. Icala elisezantsi kukuba likuvumela kuphela ukuba uthumele ii -apps zomthonyama kwi-OS uqobo lwayo. Oko kukuthi, ngelixa ukwi-VM unokwenza iWindows kwi-Linux distro, umzekelo, kwaye kwiWindows unokuqhuba nayiphi na usetyenziso lwayo, kwisitya ungayenza kuphela ngeapps ezixhaswe yinkqubo yokubamba, kule Ityala ngeLinux ...
Khumbula ukuba ulwandiso okanye inkxaso ubuchule behardware, Njenge-Intel VT kunye ne-AMD-V ikwazile ukuphucula ukusebenza kakhulu, ithatha i-2% ye-CPU ngaphezulu. Kodwa oko akusebenzi kwezinye izixhobo ezinjengememori okanye ukugcinwa ngokwako okwabelwe ukubonwa okupheleleyo, okuthetha ukufunwa kwezixhobo.
Konke oku zizinto eziza kusonjululwa zizikhongozeli Akudingeki ukuba uphinde iinkqubo ezithile ukuze ukwazi ukuhambisa usetyenziso. Umzekelo, ukuba ufuna ukwenza isikhongozeli ngeseva ye-Apache, ngomatshini ogqibeleleyo uya kuba nenkqubo yokusebenza yomgcini, i-hypervisor, inkqubo yokusebenza yeendwendwe, kunye nesoftware yale nkonzo. Kwelinye icala, ngesikhongozeli kuya kufuneka ubenayo kuphela isoftware ephumeza le nkonzo, kuba izakusebenza kwi "bhokisi" yodwa kwaye isebenzise inkqubo yokusebenza kwayo. Ngaphandle kwalonto, ukumiliselwa kweapp kukhawuleza kakhulu, ngokususa undwendwe lwe-OS.
Yintoni iDocker?
Docker yiprojekthi yomthombo ovulekileyo, phantsi kwelayisensi ye-Apache, ebhalwe kulwimi lwenkqubo yokuya kwaye isetyenziselwa ukwenza ukuthunyelwa kwezicelo ngaphakathi kwezikhongozeli. Ngamanye amagama, le software izakuvumela ukuba ulawule izikhongozeli kwiinkqubo ezahlukeneyo zokusebenza, kuba isebenza kumaqonga aliqela.
Xa kwavela iDocker, yayineenzuzo ezininzi, yaye yanwenwa ngokukhawuleza. Umbono wayo owahlukileyo wenkqubo yokusebenza kunye nokulula, kuvunyelwe ukwakha izikhongozeli ngeapps, ukumilisela, ukuzilinganisela, nokuzenza ngokukhawuleza. Indlela yokuphehlelela zonke iiapps ozifunayo kusetyenziswa ubuncinci bokusebenzisa izixhobo.
Isishwankathelo, iDocker ibonelela ngezi zinto zilandelayo iimpawu isitshixo:
- Ukuzahlula kwimeko-bume.
- Ulawulo lweekhonteyina.
- Ulawulo lwenguqulo.
- Indawo / Ukuhlangana.
- Ubuchule.
- Imveliso
- Ukusebenza kakuhle.
Kodwa yayingenazo iingxaki ezithile, njengaxa ezo khonteyina kwakufuneka zilungelelanise, zinxibelelane nabanye. Esi sesinye sezizathu ezikhokelele ekudalweni kweKubernetes ...
Njengoko ndiza kuphawula kamva Ibutho leDockerNdingathanda ukuphawula ukuba yisoftware eyenziwe ngabaphuhlisi abafanayo beDocker ukuze babenakho ukubeka iqela kuthotho lwemikhosi yeDocker kwiqela kwaye ngenxa yoko balawule amaqela embindini, ukongeza kulungelelwaniso lwezikhongozeli.
Yintoni ukubernetes?
Yayenziwe okokuqala nguGoogle, kwaye kamva yanikelwa kwi-Cloud Native Computing Foundation. Kubernetes Ikwayinkqubo efana neDocker, umthombo ovulekileyo, onelayisensi phantsi kweApache, kwaye ubhaliwe kusetyenziswa ulwimi lwenkqubo yokuHamba. Isetyenziselwa ukwenza ukuthunyelwa kunye nokulawulwa kwezicelo ezinekhonteyina. Ukongeza, ixhasa iimeko ezahlukeneyo zokuqhuba izikhongozeli, kubandakanya iDocker.
Ekugqibeleni, iiKubernetes yi isixhobo somculo weokhestra isikhongozeli esinoxanduva lokunceda izikhongozeli ezahlukeneyo zoomatshini abohlukeneyo, ulawulo lwabo, kunye nokuhanjiswa kwemithwalo phakathi kwabo. Ngokukodwa lo mbutho wenze le projekthi yinxalenye ebalulekileyo kwezi meko ...
- Ukucwangciswa okuzenzekelayo.
- Amandla okuziphilisa.
- Ukukhutshwa okuzenzekelayo kunye nokusasazwa.
- Ukulinganisa umthwalo kunye nokulinganisa okuthe tye.
- Ukuxinana okuphezulu kosetyenziso lwezixhobo.
- Imisebenzi ejolise kwimeko yeshishini.
- Ulawulo lwesicelo esembindini.
- Iziseko zophuhliso ezinokuzimela.
- Ukucwangciswa kokumiselwa.
- Ukuthembeka.
Okungakumbi malunga neKubernetes
