क्यूबलेट के लिए api.Node ऑब्जेक्ट बनाने में असमर्थ: क्लाउड प्रदाता से बाहरी आईडी प्राप्त करने में विफल: ऑब्जेक्ट

Question

ओपनस्टैक पर सिंडर वॉल्यूम का उपयोग करने के लिए मेरे पॉड्स के लिए लगातार वॉल्यूम के रूप में उपयोग करने में विफल। जैसे ही मैं क्लाउडप्रोवाइडर को कॉन्फ़िगर करता हूं और क्यूबलेट को पुनरारंभ करता हूं, क्यूबलेट क्लाउड प्रदाता से अपनी बाहरी आईडी प्राप्त करने में विफल रहता है।

ओपनस्टैक एपीआई कॉमोडो प्रमाणपत्र का उपयोग करके https के माध्यम से पहुंचा जा सकता है। कॉमोडो-सीए-बंडल नोड पर भरोसेमंद सीए के रूप में स्थापित किया गया है। एपीआई के खिलाफ कर्ल का उपयोग बिना - असुरक्षित और --cacert विकल्पों के काम करता है।

Kubelet ओपनस्टैक तक पहुँचने में सक्षम है, लेकिन यह की सूची में इस नोड खोजने के लिए विफल हो रहा है सर्वर, इस किरायेदार में, और इस क्षेत्र में। Oct 01 07:40:27 [4196]: I1001 07:40:27.133478 4196 openstack.go:201] Found 8 compute flavors Oct 01 07:40:27 [4196]: E1001 07:40:27.158908 4196 kubelet.go:846] Unable to construct api.Node object for kubelet: failed to get external ID from cloud provider: Failed to find object

क्लाउड प्रदाता द्वारा प्रदान किए गए सर्वरों की सूची से इसकी पहचान करने के लिए नोड का होस्टनाम उपयोग किया जाता है। हालांकि, इसे --hostname_overide ध्वज का उपयोग करके ओवरराइड किया जा सकता है।

आपकी कॉन्फ़िगरेशन में, मुझे लगता है कि आपने इसे आईपी के साथ ओवरराइड कर दिया है, अगर यह नोवा द्वारा रिपोर्ट किए गए सर्वर के नाम से मेल नहीं खाता है, तो आपको यह त्रुटि मिल सकती है।
