error execution phase preflight: couldn’t validate the identity of the API Server: abort connecting to API servers after timeout of 5m0s
master节点的token过期了
在master上重新创建token
kubeadm token create
然后再去节点执行 kubeadm join 192.168.11.11:6443 –token …….. 注意修改token的值
error: unable to recognize “prometheus.deploy.yaml”: no matches for kind “Deployment” in version “extensions/v1beta1”
kubernetes的版本升级的问题 “extensions/v1beta1” 换成 “apps/v1”
error: error validating “prometheus.deploy.yaml”: error validating data: ValidationError(Deployment.spec): missing required field “selector” in io.k8s.api.apps.v1.DeploymentSpec; if you choose to ignore these errors, turn validation off with –validate=false 换成 “apps/v1” 出现的问题，新版本在定义模板的时候必须定义labels,因为Deployment.spec.selector是必须字段,而他又必须和template.labels对应, spec下面添加 spec: selector: matchLabels: app: prometheus
pvc报错 no persistent volumes available for this claim and no storage class is set 看下pvc设置的大小是不是超过了pv设置的大小
pod无法解析域名
修改pod的yaml文件，添加 在spec下添加 spec: dnsPolicy: “None” dnsConfig: nameservers: - 10.0.2.3
然后重建pod 进入pod测试： kubectl exec -it pod/jenkins-56c8fbbb9-dhxtt sh
1 node(s) had taints that the pod didn’t tolerate
允许master节点部署pod kubectl taint nodes –all node-role.kubernetes.io/master- 禁止master部署pod kubectl taint nodes c1 node-role.kubernetes.io/master=true:NoSchedule
