I-Docker yinkqubo yesikhongozeli engadingi zibonelelo zininzi zokuqhuba izikhongozeli, ke Kukhanya kakhulu kwaye ke iDocker inokuba ngumgqatswa ogqibeleleyo wokuphuhlisa kunye nokuvavanya usetyenziso lwewebhu kwiRaspberry Pi.
Kanjalo, unokwenza ezinye izinto ezifana nokuqhuba umncedisi wewebhu, umncedisi weproxy okanye umncedisi wesiseko sedata kunye nokunye eDocker kwiRaspberry Pi.
Ukuba awukaqhelananga neDocker, kuya kufuneka uyazi ukuba le yiprojekthi yomthombo ovulekileyo izenza ngokuzenzekelayo ukusasazwa kwesicelo ngaphakathi kwizikhongozeli zesoftware, inikezela umaleko owongezelelweyo wokutsalwa kunye nokuzenzekela kwi-automation yesicelo kwiinkqubo ezininzi zokusebenza.
Docker isebenzisa iimpawu zokwahlulwa kwezixhobo zeLinux kernel, ezinje ngamaqela kunye nezithuba zamagama (izithuba zamagama) ukuvumela "izikhongozeli" ezizimeleyo ukuba ziqhube ngaphakathi komzekelo omnye weLinux, kuthintelwa umphezulu wokuqalisa nokugcina oomatshini benyani.
Ukulungiselela iRaspberry Pi
Ukufaka iDocker kwiRaspberry Pi yethu akukho nto iphuma kweli hlabathi kwaye Ukufakela kwayo kulula kakhulu. Kule tutorial Siza kuthatha njengesiseko inkqubo esemthethweni yeRaspberry yethu eyiRaspbian.
Ukuba awunayo le nkqubo efakwe kwiRaspberry yakho, unokujonga kwinqaku elilandelayo apho sichaza indlela yokwenza ngendlela elula. Ikhonkco yile.
Sele neRaspbian efakwe kwiRaspberry pi yethu, siza kuhlaziya iipakethe kunye neRaspbian APT yogcino lwepakethe yecache ngalo myalelo ulandelayo:
sudo apt update
Ngoku, kuya kufuneka uhlaziye zonke iipakeji zesoftware ezintsha eziye zafunyanwa kwiRaspbian. Ngenxa yoku kufuneka siphumeze lo myalelo ulandelayo:
sudo apt upgrade
Ngeli xesha, iipakethe zesoftware kufuneka zihlaziywe.
Ngoku kufuneka ufakele ii-kernel-headers zendlela yokusebenza. Oku kubalulekile, kuba ukuba awuyifaki i-kernel headers, i-Docker ayiyi kusebenza.
Ukufakela i-kernel-headers kufuneka usebenzise lo myalelo ulandelayo kwi-terminal:
sudo apt install raspberrypi-kernel raspberrypi-kernel-headers
Ngayo yonke into engentla ilungile, ngoku sinokuqhubekeka kufakelo lweDocker kwiRaspberry Pi yethu esiyithandayo, kuba siqinisekile ukuba sinazo zonke iipakethe zenkqubo ehlaziyiweyo.
Ukufaka iDocker kwiRaspberry Pi
Ukufakwa kweDocker Siyenza ngokwenza lo myalelo ulandelayo kwi-terminal:
curl -sSL https://get.docker.com | sh
Le nkqubo yokukhuphela kunye nokufaka ingathatha ixesha, ngoko ke ndicebisa ukuba uthathe ixesha lakho.
Ngoku ngokufakela iDocker kwinkqubo yethu yeRaspberry Pi, Ngoku siqala umsebenzi wokuphunyezwa yeDocker ukuze ukwazi ukuyisebenzisa.
Kule nyathelo lokuqala yongeza umsebenzisi wenkqubo yethu "pi" (Okumiselweyo kwiRaspbian) kwiqela le-docker. Ke ngoko, uya kuba nakho ukwenza kunye nokulawula izitya, imifanekiso, imiqulu, njl. I-Docker ngaphandle kwe-sudo okanye amalungelo aphezulu omsebenzisi.
Ukuba udale umsebenzisi owahlukileyo, kufuneka utshintshe "pi" kumsebenzisi wakho kumyalelo. Ukongeza umsebenzisi we-pi kwiqela leDocker Kufuneka nje benze lo myalelo ulandelayo:
sudo usermod -aG docker pi
Wenze olu tshintsho ngoku, Kuya kufuneka ukuba siqale ngokutsha inkqubo yethu, ukuze utshintsho olwenziweyo lulayishwe ekuqaleni kwenkqubo kwaye ukongezwa kwiqela lethu leDocker liyasetyenziswa.
Ungaphinda uqalise inkqubo yakho ngokusebenzisa lo myalelo ulandelayo kwi-terminal:
sudo reboot
Nje ukuba inkqubo iphinde iqale, siphinda siyifake kwaye sivule i-terminal. Kuyo siza kwenza lo myalelo ulandelayo ku qinisekisa ufakelo lweDocker kwaye sele lusebenza kwinkqubo:
docker version
Njengoko ubona, iDocker sele isebenza ngokugqibeleleyo kwiRaspberry Pi yakho.
Ngoku kuya kufuneka ubeke kuphela isikhongozeli sakho sokuqala. Ukwenza oku, unokukhangela enye kwiphepha leDocker, elinezicelo ezininzi. Ikhonkco yile.
