1、kubernetes dashboard apply报错
Mac终端执行命令： kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.2.0/aio/deploy/recommended.yaml报
The connection to the server raw.githubusercontent.com was refused – did you specify the right host or port?
解决方案：
1）查询raw.githubusercontent.com域名IP
https://ip.tool.chinaz.com/raw.githubusercontent.com查询raw.githubusercontent.com
2）hosts文件（/etc/hosts）中新增域名ip映射
185.199.108.133 raw.githubusercontent.com
185.199.109.133 raw.githubusercontent.com
185.199.110.133 raw.githubusercontent.com
185.199.111.133 raw.githubusercontent.com
3）重新执行kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.2.0/aio/deploy/recommended.yaml
4）终端输入kubectl proxy启动服务，默认提示如下：Starting to serve on 127.0.0.1:8001
5）浏览器地址栏访问kubernetes-dashboard 验证（默认端口8001）
http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/#/pod?namespace=default出现如下说明kubernetes-dashboard部署成功
参考官方文档：https://github.com/kubernetes/dashboard/
2、mysql语句后需要带上分号;
未带分号如下：
带分号：
3、kubectl apply -f config.yaml报错
Error from server (BadRequest): error when creating “config.yaml”: ConfigMap in version “v1” cannot be handled as a ConfigMap: v1.ConfigMap.Data: ReadString: expects ” or n, but found 1, error found in #10 byte of …|ASSWORD”:123456,“ACC|…, bigger context …|sion”:“v1”,“data”:{“ACCOUNT_DATASOURCE_PASSWORD”:123456,“ACCOUNT_DATASOURCE_URL”:”jdbc:mysql://mysql|…
解决方案：
提示少了”引号，经检查config.yaml发现密码如果是数值类型需要加上引号
改成”123456″后重新执行提示configmap/common-config created说明执行成功，即
登录kubernetes-dashboard 中Config Maps即可查看加载到配置信息
4、kubectl -n kubernetes-dashboard get secret $(kubectl -n kubernetes-dashboard get sa/admin-user -o jsonpath=”{.secrets[0].name}”) -o go-template=”{
{.data.token | base64decode}}”
报错Error from server (NotFound): serviceaccounts “admin-user” not found
Error executing template: template: output:1:16: executing “output” at : wrong number of args for base64decode: want 1 got 0. Printing more information for debugging the template:
1）cat <<EOF | kubectl apply -f –
apiVersion: v1
kind: ServiceAccount
metadata:
name: admin-user
namespace: kubernetes-dashboard
EOF
2）
cat <<EOF | kubectl apply -f –
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
name: admin-user
roleRef:
apiGroup: rbac.authorization.k8s.io
kind: ClusterRole
name: cluster-admin
subjects:
-
kind: ServiceAccount
name: admin-user
namespace: kubernetes-dashboard
EOF
输入：kubectl -n kubernetes-dashboard get secret $(kubectl -n kubernetes-dashboard get sa/admin-user -o jsonpath=”{.secrets[0].name}”) -o go-template=”{
{.data.token | base64decode}}”
出现类似如同token，token有效期失效后，过期后需重新生成
