minikube 部署时的一些坑

1、部署完minikube后，想在其中部署一个deployment。但是pod一直是显示pending。
用kubectl describe pod 查看，显示
shell Warning FailedScheduling 2m (x57 over 17m) default-scheduler 0/1 nodes are available: 1 node(s) had taints that the pod didn't tolerate.
这与kubernetes调度算法中的Taints和Tolerations有关
Taints的含义是：此节点已被key=value污染，Pod调度不允许（PodToleratesNodeTaints策略）或尽量不（TaintTolerationPriority策略）调度到此节点，除非是能够容忍（Tolerations）key=value污点的Pod
所以在pod中添加Tolerations定义为[{"key":"xxx","value":"xxx","effect":"NoSchedule"}]，则允许调度到此节点
tolerations:
- key: "xxx"
operator: "Equal"
value: "xxx"
effect: "NoSchedule"
