Minikube : इंस्टॉल करें2024/05/13

एकल नोड पर Kubernetes क्लस्टर को कॉन्फ़िगर करने के लिए Minikube स्थापित करें।

[1]	पहले एक हाइपरवाइज़र स्थापित करें जो Minikube द्वारा समर्थित हो। इस उदाहरण पर, इंस्टॉल करें। अन्य हाइपरवाइज़र के लिए, VirtualBox, VMware Fusion, HyperKit का उपयोग करना संभव है।
[2]	Snapd चलाएँ, यहाँ देखें।
[3]	Minikube और अन्य आवश्यक उपकरण स्थापित करें।
