Kubernetes : Worker नोड्स जोड़ें2024/06/07 |
|
मौजूदा Kubernetes क्लस्टर में नए Worker नोड्स जोड़ें।
यह उदाहरण क्लस्टर वातावरण पर आधारित है, जो इस प्रकार है।
+----------------------+ +----------------------+
| [ ctrl.srv.world ] | | [ dlp.srv.world ] |
| Manager Node | | Control Plane |
+-----------+----------+ +-----------+----------+
eth0|10.0.0.25 eth0|10.0.0.30
| |
------------+--------------------------+-----------
| |
eth0|10.0.0.51 eth0|10.0.0.52
+-----------+----------+ +-----------+----------+
| [ node01.srv.world ] | | [ node02.srv.world ] |
| Worker Node#1 | | Worker Node#2 |
+----------------------+ +----------------------+

On a new Node, क्लस्टर में शामिल होने के लिए सामान्य सेटिंग्स कॉन्फ़िगर करें, यहां देखें। |
| [2] | कंट्रोल प्लेन नोड पर जॉइन कमांड की पुष्टि करें। |

| [3] | नये नोड पर join कमांड चलाएँ। |

| [4] | प्रबंधक नोड पर सेटिंग्स सत्यापित करें। यदि नए नोड की स्थिति [स्थिति = तैयार] हो जाती है तो यह ठीक है। |
