Taswirar Kubernetes + Helm

«Hanya ita ce hanya mafi kyau don ganowa, rarrabawa da amfani da software da aka gina don Kubernetes."

Lokacin da kuke da tarin aikace-aikacen Kubernetes da ke gudana, turawa da sabunta su ya zama zafi, musamman idan kuna buƙatar sabunta alamar hoton docker kafin turawa. Taswirar Helm suna ƙirƙirar fakiti waɗanda aikace-aikace da tsari za a iya ayyana su, shigar da su, da sabunta su lokacin da aka ƙaddamar da su akan gungu ta tsarin sakin.

Kunshin Kubernetes a Helm ana kiransa ginshiƙi kuma ya ƙunshi bayanai da yawa waɗanda ke haifar da misalin Kubernetes.

Tsarin yana da amfani sosai: ya ƙunshi bayanai masu ƙarfi game da yadda aka tsara taswirar. Saki shine misalin data kasance a cikin tari haɗe da ƙayyadaddun tsari.

Ba kamar apt ko yum ba, ana gina taswirar Helm (watau fakiti) a saman Kubernetes kuma suna cin gajiyar tsarin gine-ginen ta, kuma mafi kyawun abu shine ikon yin la'akari da ƙima daga farkon. Ana adana sigogin duk hotunan da Helm ke amfani da su a cikin wurin yin rajista da ake kira Helm Workspace.

Bi waɗannan shawarwarin kuma ƙwarewar Kubernetes za ta yi laushi. Ƙaddamar da lokacinku na kyauta ga babban burin aikace-aikacen Kubernetes a cikin gungu. Idan kuna da tambayoyi game da Kubernetes ko Helm, rubuta mana.
