调度到master节点
一般来说，kubernetes 的pod是不在master 节点上运行的。 如果要求pod 必须被调度到master 节点上运行，可以修改pod 的 toleration 和 affinity。 toleration和affinity： 在pod加上toleration和affinity配置 yaml 1 2 3 4 5 6 7 8 9 10 11 12 13 spec: tolerations: - key: "node-role.kubernetes.io/master" operator: "Equal" value: "true" effect: "NoSchedule" affinity: nodeAffinity: requiredDuringSchedulingIgnoredDuringExecution: nodeSelectorTerms: - matchExpressions: - key: node-role.kubernetes.io/master operator: Exists go 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 + Operator: apiv1.TolerationOpExists, + Effect: apiv1.TaintEffectNoSchedule, + }, + }, + Affinity: &apiv1.Affinity{ + NodeAffinity: &apiv1.NodeAffinity{ + RequiredDuringSchedulingIgnoredDuringExecution: &apiv1.NodeSelector{ + NodeSelectorTerms: []apiv1.NodeSelectorTerm{ + apiv1.NodeSelectorTerm{ + MatchExpressions: []apiv1.NodeSelectorRequirement{ + apiv1.NodeSelectorRequirement{ + Key: "node-role.kubernetes.io/master", + Operator: apiv1.NodeSelectorOpExists, + }, + }, + }, + }, + },
