Kubernetes（k8s）中dashboard的部署。

标签：initial names git dem extension complete not ready 编辑 1、k8s的dashboard的安装部署，首先需要将压缩包下载下来，然后进行解压缩操作。 查看配置文件dashboard-deploy.yaml，并对配置进行修改。 首先，需要将kubernetes-dashboard-amd64下载下来，然后上传到私有仓库里面，方便使用。 dashboard-deploy.yaml，对配置进行修改，具体内容，如下所示。 修改的地方，如下所示： 配置完毕，创建deployment，如下所示： 修改dashboard-svc.yaml配置文件，其中port是VIP的端口，targetPort是容器的端口，访问vip的端口80就会跳转到targetPort的9090端口。 [root@k8s-master dashboard]# vim dashboard-svc.yaml 开始创建svc，命令如下所示： 创建完毕，查看是否已经正常启动了。 此时，就可以进行访问了，服务已经Running了。 2、首先，可以访问一下api-server，可以使用8080端口号。访问地址http://192.168.110.133:8080/。 接下来访问倒数第二行的/ui/，访问的效果，如下所示： 报错，如下所示： 这里查看k8s的版本，使用kubectl version。 注意：k8s v1.5 web界面，kubernetes-dashboard v1.5 ，k8s的安装版本和kubernetes-dashboard的版本对应，此时对k8s了解还不是很深，只能一点点摸索了。 kubernetes dashboard镜像获取：docker pull registry.cn-hangzhou.aliyuncs.com/google-containers/kubernetes-dashboard-amd64:v1.5.0。 这里重新tag，并push到自己的私有镜像仓库了，命令如下所示： 然后将创建的Pod删除掉，修改deployment配置文件dashboard-deploy.yaml。 修改内容，如下所示： 删除创建的delpoyment、svc。 再次新建delpoyment、svc。 访问路径，查看界面。http://192.168.110.133:8080/ui/ k8s的dashboard是k8s的一个web界面的工具，可以创建多种资源或者删除资源。注意，如果三台机器挂起之后，第二次直接启动，你的dashboard好像不能访问耶，我直接重启了三台机器就行了，因为我的所有组件服务都是设置的开机自启动，避免了一些麻烦。 使用k8s的dashboard创建资源来创建一个资源，有两种方式，第一种是按照规则填写，第二种是上传Json格式的文件。 可以看到，默认是Deployment，这个很多东西估计和自己的dashboard的版本有关，所以根据自己的情况进行判断即可。 接下来，可以多这个Deployment进行删除或者编辑配置文件，这里将它删除掉。 然后，可以将创建的Service删除掉，如下所示： 这里Replica Sets也删除掉，deployment并不像RC直接去启动Pod，它们之间的区别是deployment会启动一个RS，RS拥有RC的百分之九十的功能，比RC的功能还多一些。 此时，可以看到创建的两个Pod也就删除掉了。 Kubernetes（k8s）中dashboard的部署。 标签：initial names git dem extension complete not ready 编辑 原文地址：https://www.cnblogs.com/biehongli/p/13159610.html 1 [root@k8s-master ~]# cd k8s/
