Ungayifaka kanjani i-Docker ku-Ubuntu 18.04 nakwezokuphuma?

Ukusetshenziswa kwe Ukubona okuhle kakhulu sekuyafaneleka nsuku zonke, ngoba ngentuthuko nezinto ezintsha abazinikezayo, zenza kube lula ukusebenzisa ubuchwepheshe. Lokhu kwenza ukuthi zombili izinkampani nabasebenzisi bokugcina babe nokukhululeka nokuphepha kokukwazi ukukusebenzisa.

Naye ungenza imisebenzi ehlukahlukene futhi usebenzise zombili izinhlelo zokusebenza nezinhlelo zokusebenza ngaphandle kokuyekethisa uhlelo olusebenzayo lokusingathwa, ngoba basebenza endaweni eyihlane ngokuphelele.

Kulesi senzakalo ake sibheke iDocker, okuyinto uhlelo lokusebenza lomthombo ovulekile wesikhulumi lokho ihambisa ukuthunyelwa kwezinhlelo zokusebenza ngaphakathi kweziqukathi zesoftware, ukuhlinzeka ngesendlalelo esingeziwe sokukhishwa nokuzenzakalelayo kwe-Virtualization ezingeni lesistimu yokusebenza ku-Linux.

Abaningi benu sebevele bezwile noma basebenzise iDocker ngoba isivele idume kakhulu ngayo ngokuyisisekelo singenza ukubonwa kwesitsha ezingeni lohlelo lokusebenza, kepha ngesiqinisekiso sokuthi i-Docker isebenzisa izici zokuhlukaniswa kwemithombo ye-Linux kernel njengama-cgroups nezikhala zamagama ukuvumela iziqukathi ezizimele ukuthi zisebenze ngaphakathi kwesimo esisodwa se-Linux, ukugwema isisekelo sokuqala nokugcina imishini ebonakalayo.

UDocker uphatha izinhlobo ezimbili leyo ekhokhelwa izinkampani ze-EE (I-Enterprise Edition) kanti enye inguqulo yamahhala okuyiyona evela emphakathini we-CE (Uhlelo Lomphakathi).

Ngecala lethu vSiyakwazi ukusebenzisa inguqulo yamahhala.

Ngaphambi kokuqala ukufakwa kufanele sikhiphe noma yikuphi ukufakwa okwenziwe ngaphambili uma kungenzeka kubuyekezwe, Ngaphezu kokukutshela ukuthi le ndlela isebenza naku-Ubuntu Artful 17.10, Ubuntu Xenial 16.04 naku-Ubuntu Trusty 14.04.

Manje dsidinga ukuvula i-terminal (Ctrl + Alt + T) kanye sebenzisa umyalo olandelayo Ukususa ukufaka kwangaphambilini kwe-Docker:

sudo apt-get remove docker docker-engine docker.io

Kwenziwe lokhu, ukuzetime kufanele sivuselele amakhosombe ethu no:

sudo apt-get update

Futhi noma iyiphi iphakethe:

sudo apt-get upgrade

Faka i-Docker CE ku-Ubuntu 18.04

Kufanele sifake ukuncika okuthile kuyadingeka ku-Docker ngale miyalo:

sudo apt-get install \

apt-transport-https \

ca-certificates \

curl \

software-properties-common

Kwenziwe lokhu manje kufanele singenise ukhiye we-GPG:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Kufanele siqinisekise ukuthi izigxivizo zeminwe Ulwandle Ingxenye #: 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88, ngifuna izinhlamvu zokugcina eziyi-8 zeminwe.

Kulokhu singaqhuba lo myalo:

sudo apt-key fingerprint 0EBFCD88

Okufanele kubuyise into enjengale:

pub   4096R/0EBFCD88 2017-02-22

Key fingerprint = 9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88

uid Docker Release (CE deb) <docker@docker.com>

sub 4096R/F273FCD8 2017-02-22

Manje kufanele sengeze indawo yokugcina izinto ohlelweni ngomyalo olandelayo:

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

Uma uthola iphutha ungalifaka ngesandla ngokuhlela imithombo yolwazi.list, ukwenza lokhu kusuka esigungwini osithayiphayo:

sudo nano /etc/apt/sources.list

Futhi ungeza umugqa olandelayo, mhlawumbe ekugcineni:

deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable

Uyifaka kuphi iBionic uma ungasebenzisi i-18.04 ngobuciko be-17.10, i-xenial ye-16.04 noma i-trusty ye-14.04.

Uma lokhu sekwenziwe, sibuyekeza uhlu lwethu lwezinqolobane nge:

sudo apt-get update

Futhi manje manje sesingafaka iDocker kusistimu yethu, kufanele sithayiphe umyalo olandelayo:

sudo apt-get install docker-ce

Lapho ukufakwa sekuqediwe, kungakuhle ukuthi uqale kabusha ikhompyutha yakho, ngoba izinsizakalo ze-Docker ziqala ngokuzenzakalela lapho uqala uhlelo lwakho.

para qinisekisa ukuthi iDocker ifakwe ngempumelelo futhi lokho sekuvele kusebenza ohlelweni singenza isivivinyo esilula, kufanele nje sivule ukuphela futhi sisebenzise umyalo olandelayo:

sudo docker run hello-world

Okokugcina kufanele sengeze iqembu le-Docker kumsebenzisi wethu ngoba lokhu kudalwe ohlelweni, kepha akufakwa ngokuzenzakalela, kulokhu esigungwini esisisebenzisayo:

sudo usermod -aG docker $USER

Futhi i-voila, uma sifuna ukuvuselela inguqulo yethu ye-Docker iye kweyakamuva kakhulu, kufanele sisebenzise kuphela:

sudo apt-get install docker-ce

Uma ufuna ukwazi kabanzi ngayo, ungaxhumana nomhlahlandlela wayo wokufaka ukuthola amapulatifomu amaningi, kusixhumanisi yilokho.
