Uyifaka njani i-Docker kwi-Ubuntu 18.10 kunye neziphumo?

I-Docker ngokungathandabuzekiyo yiprojekthi enkulu evulekileyo ixhaswa liziko loshishino elinegama elifanayo eyenza kube lula kakhulu ukuqhuba inkqubo yokwenza isicelo ngaphakathi kwendawo ethe qelele ebizwa ngokuba sisiqulathi okanye isikhongozeli.

I-Docker, ngokungafaniyo nomatshini obonakalayo, ine-kernel yayo, isikhongozeli sixhomekeke kwikernel yenkqubo yokusebenza ye-Host, evumela ukuba ikhanyise kwaye ibaleke ngokukhawuleza okukhulu.

Esi sisixhobo esilula esinika amandla ekhompyuter yethu ekuphuhliseni nasekulawuleni usetyenziso lwezeshishini.

NgeDocker ngokusisiseko sinokwenza into ebonakalayo kwinqanaba lenkqubo yokusebenza, kodwa ngesiqinisekiso sokuba iDocker isebenzisa izixhobo ezizimeleyo zokwahlulahlula i-kernel yeLinux, ezinje ngamaqelana kunye neendawo zamagama ukuvumela izikhongozeli ezizimeleyo ukuba zisebenze kwimeko enye yeLinux, ukuthintela ngaphezulu kokuqala nokugcina oomatshini ababonakalayo.

Docker Iphatha iinguqulelo ezimbini, enye ihlawulelwa iinkampani ze-EE (Ushicilelo lweshishini) Enye inguqulelo yasimahla yona ivela kuluntu lwe-CE (UHlelo loLuntu).

Ngokusebenzisa izikhongozeli, izixhobo zinokuhlukaniswa, Iinkonzo ezithintelweyo, kwaye iinkqubo zinikwa amandla okuba nembono yabucala phantse yangasese yenkqubo yokusebenza ngenkqubo yayo yesazisi sendawo, inkqubo yenkqubo yefayile, kunye nonxibelelwano lwenethiwekhi. Izikhongozeli ezininzi zabelana ngekernel efanayo, kodwa isikhongozeli ngasinye sinokuthintelwa ekusebenziseni kuphela isixa esichaziweyo sezixhobo ezinjenge-CPU, inkumbulo, kunye ne-I / O.

Umbono wokwenza oku kukubonelela ngeendlela zokutsala ezivumela inkqubo ukuba iqhubeke nokuba yeyiphi na esebenzayo.

Ke ngoko, oku kuluncedo kakhulu kubalawuli benkqubo abalawula iikhompyuter ezahlukeneyo.

Ukudibanisa i-Docker kunye ne-Ubuntu 18.10 kusebenza ngokubheja okukhuselekileyo kokusebenza ngokulula kunye nokuphathwa kokuphathwa kwesikhongozeli.

Ukufakwa kwe-Docker kwi-Ubuntu 18.10 kunye neziphumo

Okwangoku kukho iphakheji yeDocker ye-Ubuntu 18.10, kodwa oku kudala ukungaboni ngasonye, ​​ukuba awukwazanga ukufaka iDocker ngokuchanekileyo kwinkqubo yakho, sinokukunceda.

Okokuqala kufuneka senze uhlaziyo lweephakeji zethu, ke kufuneka sivule i-terminal kwaye kuyo siza kwenza le miyalelo ilandelayo:

sudo apt update

sudo apt upgrade

Uyenzile ngoku kwayeKuyimfuneko ukuba sifake ezinye iipakeji eziyimfuneko kufakelo lweDocker, sisebenzisa lo myalelo ulandelayo:

sudo apt-get install apt-transport-https ca-certificates curl gnupg software-properties-common

Ahora si todo sale bien puedes realizar la instalación de Docker directamente con el siguiente comando:

[sourcecode language="bash"]sudo apt-get install docker-ce

Ukuba ufakelo aluzange lwenziwe, kuya kufuneka ukuba ufumane umyalezo onje:

Reading package lists... Done

Building dependency tree

Reading state information... Done

Package docker-ce is not available, but is referred to by another package.

This may mean that the package is missing, has been obsoleted, or

is only available from another source

E: Package 'docker-ce' has no installation candidate

Impazamo Singayisombulula ngokuchwetheza le miyalelo ilandelayo kwisiphelo sendlela. Kuqala siza kongeza isitshixo se-gpg kwinkqubo, kuba kufuneka siyikhuphele:

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

Songeza indawo yokugcina kwinkqubo:

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu cosmic nightly "

Qaphela: xa usongeza le ndawo yokugcina sisebenzisa ingxelo yophuhliso, kodwa kwabo bayithandayo sinokunyanzela inkqubo ukuba ithathe ingxelo ezinzileyo yokugcina iBionic.

Ukwenza oku, kufuneka sichwetheze oku kulandelayo:

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable"

Kwaye ekugqibeleni singasifaka isicelo kunye:

sudo apt install docker-ce

Uyisebenzisa kanjani iDocker?

Ekupheleni kofakelo, ukuze inkonzo iqhubeke kuqaliso lwenkqubo, kufuneka sisebenzise le miyalelo ilandelayo:

sudo systemctl enable docker

sudo systemctl start docker

Ukuqinisekisa ukuba iDocker isebenza ngokupheleleyo, licebo elilungileyo ukujonga inqanaba lenkonzo:

sudo systemctl status docker

Okokugqibela, ukuba ufuna ukubona uhlobo lweDocker.

docker -v
