在Easypack中提供了多套Kubernetes快速部署的工具，基于Bash脚本和Ansible的，Ansible的方式也有基于K3S和普通的Kubernetes的两种。这篇文章介绍一下普通Kubernetes版本下的Ansible部署工具中Dashboard升级至2.0.0版本的情况。

# 事前准备 #

本文使用Kubernetes 1.17.2，可参看下文进行快速环境搭建：

*  [单机版本或者集群版本环境搭建][Link 1]

[root@host131 ansible]# kubectl get node -o wide
    NAME              STATUS   ROLES    AGE     VERSION   INTERNAL-IP       EXTERNAL-IP   OS-IMAGE                KERNEL-VERSION          CONTAINER-RUNTIME
    192.168.163.131   Ready    <none>   2m25s   v1.17.2   192.168.163.131   <none>        CentOS Linux 7 (Core)   3.10.0-957.el7.x86_64   docker://19.3.5
    [root@host131 ansible]#

*  事前环境确认: service、pod与deployment

[root@host131 ansible]# kubectl get service -A |grep dashboard
    [root@host131 ansible]# kubectl get pod -A |grep dashboard
    [root@host131 ansible]# kubectl get deployment -A |grep dashboard
    [root@host131 ansible]#

# Dashboard安装 #

执行如下命令即可完成Metrics Server的安装

[root@host131 ansible]# ansible-playbook dashboard/tests/test.yml 
    
    PLAY [localhost] *********************************************************************************************************************************
    
    TASK [dashboard : create dirs for dashboard] *****************************************************************************************************
    changed: [localhost] => (item=/etc/k8s/dashboard)
    
    TASK [dashboard : create dashboard yaml service file] ********************************************************************************************
    changed: [localhost]
    
    TASK [dashboard : delete & create kubectl service] ***********************************************************************************************
    changed: [localhost]
    
    TASK [dashboard : confirm dashboard service state] ***********************************************************************************************
    FAILED - RETRYING: confirm dashboard service state (15 retries left).
    changed: [localhost]
    
    TASK [dashboard : drop dashboard service account if exist then create the account] ***************************************************************
    changed: [localhost]
    
    TASK [dashboard : drop clusterrolebinding for dashboard if exist then create the clusterrolebinding] *********************************************
    changed: [localhost]
    
    PLAY RECAP ***************************************************************************************************************************************
    localhost                  : ok=6    changed=6    unreachable=0    failed=0   
    
    [root@host131 ansible]#

注：FAILED - RETRYING: confirm dashboard service state (15 retries left).的提示信息没有问题，只是在等待服务启动的轮询而已。

## 结果确认 ##

使用kubectl命令可以确认到，pod、deployment以及service全部生成并正常运行

[root@host131 ansible]# kubectl get pod -A |grep dashboard
    kubernetes-dashboard   dashboard-metrics-scraper-7b8b58dc8b-wx6pp   1/1     Running   0          28s
    kubernetes-dashboard   kubernetes-dashboard-6b77748b8f-gv68k        1/1     Running   0          28s
    [root@host131 ansible]# kubectl get service -A |grep dashboard
    kubernetes-dashboard   dashboard-metrics-scraper   ClusterIP   10.254.115.208   <none>        8000/TCP        34s
    kubernetes-dashboard   kubernetes-dashboard        NodePort    10.254.169.84    <none>        443:33307/TCP   35s
    [root@host131 ansible]# kubectl get deployment -A |grep dashboard
    kubernetes-dashboard   dashboard-metrics-scraper   1/1     1            1           42s
    kubernetes-dashboard   kubernetes-dashboard        1/1     1            1           42s
    [root@host131 ansible]#

*  获取token

[root@host131 shell]# . ./common-util.sh 
    [root@host131 shell]# display_dashboard_token
    ## dashboard_secrete: dashboard-admin-token-772qk

# 登录确认 #

使用上述token信息可以直接登录

可以切换至所有的命名空间角度进行状态确认

但是此时Pod等资源详细信息仍然无法确认
