I-Docker uhlelo lwesitsha olungadingi izinsiza eziningi ukusebenzisa izitsha, okwenza kube lula kakhulu . Ngakho-ke, i-Docker ingaba yindlela ephelele yokuthuthukisa nokuhlola izinhlelo zokusebenza zewebhu ku-Raspberry Pi.
Vele, ungenza ezinye izinto njengokusebenzisa iseva yewebhu, iseva yommeleli, noma iseva yedatha nokuningi ku-Docker ku-Raspberry Pi.
Uma ungakajwayelani ne-Docker, kufanele wazi ukuthi iphrojekthi yomthombo ovulekile ezenzakalelayo ukuthunyelwa kwezinhlelo zokusebenza ngaphakathi kweziqukathi zesofthiwe , ihlinzeka ngesendlalelo esengeziwe sokukhushulwa kanye nokwenza ngokuzenzakalela kokusetshenziswa kwezinhlelo zokusebenza kuzo zonke izinhlelo zokusebenza eziningi.
I-Docker isebenzisa izici zokuhlukanisa izinsiza ze-kernel ze-Linux, njenge-cgroups kanye ne-namespaces , ukuvumela "iziqukathi" ezizimele ukuthi zisebenze ngaphakathi kwesibonelo esisodwa se-Linux, zigwema izindleko zokuqala nokugcina imishini ebonakalayo.
Ukulungiselela i-Raspberry Pi
Ukufaka i-Docker ku-Raspberry Pi yakho kulula kakhulu futhi kulula kakhulu . Kulesi sifundo, sizosebenzisa uhlelo lokusebenza olusemthethweni lwe-Raspberry Pi, i-Raspbian, njengesisekelo sethu.
Uma ungakafaki lolu hlelo ku-Raspberry Pi yakho, ungabheka isihloko esilandelayo lapho sichaza khona ukuthi singakwenza kanjani kalula. Isixhumanisi silapha.
Njengoba i-Raspbian isifakiwe ku-Raspberry Pi yethu, sizobuyekeza amaphakheji kanye ne-Raspbian APT package repository cache sisebenzisa umyalo olandelayo:
sudo apt update
Manje, kufanele ubuyekeze wonke amaphakheji wesoftware amasha atholakele evela eRaspbian. Ngalokhu kufanele senze umyalo olandelayo:
sudo apt upgrade
Okwamanje, amaphakheji wesoftware adinga ukuvuselelwa.
Manje, udinga ukufaka ama-kernel headers ohlelweni lwakho lokusebenza. Lokhu kubalulekile, ngoba uma ungawafaki ama-kernel headers, i-Docker ngeke isebenze.
Ukufaka izihloko ze-kernel, konke okumele ukwenze ukusebenzisa umyalo olandelayo ku-terminal:
sudo apt install raspberrypi-kernel raspberrypi-kernel-headers
Ngakho konke okungenhla sekulungile, manje singaqhubeka nokufakwa kwe-Docker ku-Raspberry Pi yethu ethandekayo, ngoba siqiniseke ngokuphelele ukuthi sinawo wonke amaphakheji abuyekeziwe ohlelo.
Faka iDocker ku-Raspberry Pi
Sifaka i-Docker ngokusebenzisa umyalo olandelayo ku-terminal:
curl -sSL https://get.docker.com | sh
Le nqubo yokulanda nokufaka ingathatha isikhashana, ngakho-ke ngiphakamisa ukuthi uthathe isikhathi sakho.
Manje njengoba i-Docker isifakiwe ohlelweni lwethu lwe-Raspberry Pi, singaqala inqubo yokusebenzisa i-Docker ukuze sikwazi ukuyisebenzisa.
Isinyathelo sokuqala ukwengeza umsebenzisi wakho wesistimu "pi" (umsebenzisi ozenzakalelayo ku-Raspbian) eqenjini le-docker. Lokhu kuzokuvumela ukuthi udale futhi uphathe izitsha ze-Docker, izithombe, amavolumu, njll., ngaphandle kwamalungelo e-sudo noma e-superuser.
Uma udale umsebenzisi ohlukile, kufanele ufake igama lakho lomsebenzisi esikhundleni sika-“pi” emyalweni. Ukuze ungeze umsebenzisi we-pi eqenjini le-Docker, mane usebenzise umyalo olandelayo:
sudo usermod -aG docker pi
Njengoba sesishintshe lolu shintsho, manje kuzodingeka siqalise kabusha uhlelo lwethu ukuze izinguquko zilayishwe ekuqaleni kohlelo futhi kusetshenziswe ukwengezwa komsebenzisi wethu eqenjini le-Docker.
Bangakwazi ukuqala kabusha uhlelo lwabo ngokusebenzisa umyalo olandelayo ku-terminal:
sudo reboot
Uma uhlelo seluqalile kabusha, ngena ngemvume bese uvula i-terminal. Sebenzisa umyalo olandelayo ukuqinisekisa ukuthi i-Docker ifakiwe futhi iyasebenza ohlelweni:
docker version
Njengoba ukwazi ukubona, iDocker isebenza ngokuphelele ku-Raspberry Pi yakho.
Manje udinga nje ukufaka isitsha sakho sokuqala. Ungasithola kuwebhusayithi ye-Docker, enezinhlelo zokusebenza eziningi. Nasi isixhumanisi.
