kubectl explain HorizontalPodAutoscaler.spec.minReplicas\r\nKIND: HorizontalPodAutoscaler\r\nVERSION: autoscaling\/v1\r\n\r\nFIELD: minReplicas <integer>\r\n\r\nDESCRIPTION:\r\n minReplicas is the lower limit for <\/span>the number of replicas to which the\r\n autoscaler can scale down. It defaults to 1 pod. minReplicas is allowed to\r\n be 0 if <\/span>the alpha feature gate HPAScaleToZero is enabled and at least one\r\n Object or External metric is configured. Scaling is active as long as at\r\n least one metric value is available.\r\n<\/code><\/pre>\n\u5982\u679c\u542f\u7528\u4e86HPAScaleToZero\u7684alpha\u529f\u80fd\uff0c\u5e76\u4e14\u914d\u7f6e\u4e86\u81f3\u5c11\u4e00\u4e2a\u5bf9\u8c61\u6216\u5916\u90e8\u6307\u6807\uff0c\u90a3\u4e48minReplicas\u53ef\u4ee5\u4e3a0\u3002<\/p><\/blockquote>\n
