Question

我是openshift的新手。我正在尝试完成一些基本的安装选项。首先，我能够下载并运行流浪者图像。当我这样做时，我能够登录并看到几个项目和容器正在运行。接下来我尝试了二进制安装。所以我下载了openshift origin服务器v1.3.1解开它并运行以下内容：

sudo openshift start

似乎openshift开始了，但我确实注意到输出中的一些可疑行如下：

服务器启动后我可以登录，但系统用户似乎没有权限做很多事情。例如，系统用户无法查看群集中的任何项目或服务。运行某些 oc 命令似乎表明系统用户没有适当的权限，如下所示：

 #./oc login https://localhost:8443 Authentication required for https://localhost:8443 (openshift) Username: system Password: Login
 successful.

 You don't have any projects. You can try to create a new project, by
 running

     oc new-project <projectname>

 # ./oc new-project default 
 Error from server: project "default" already exists
 # ./oc get services --all-namespaces 
 User "system" cannot list all services in the cluster

似乎我必须遗漏一些关于如何从二进制发行版中启动openshift的基本内容。我在文档中找不到任何与此问题相关的内容。

Answer 1

不确定您的环境是什么样的，因此以下内容可能无法100％运行。

但你可以尝试以下方法：

oc whoami
oc login -u system:admin
oc whoami

系统：管理员帐户是您的root帐户，您可以从他们创建其他用户帐户。

我发现运行OpenShift开发实例的最佳方法是通过oc cluster up。 https://github.com/openshift/origin/blob/master/docs/cluster_up_down.md。这在docker的openshift上运行容器化版本。可能值得一试，因为您以前的安装方法似乎有一些错误。

Answer 2

如果你想手动完成这项工作（如上所述没有oc群集）

export KUBECONFIG=/full/path/to/openshift.local.config/master/admin.kubeconfig

sudo chmod a+rwX -R /path/to/openshift.local.config/

oadm policy add-cluster-role-to-user cluster-admin demo (demigod mode)

oc whoami 
system:admin

oc projects
You have access to the following projects and can switch between them with 'oc project <projectname>':

    default
    kube-system
    openshift
    openshift-infra
  * test

这不是一个生产设置，这只是为了搞乱。

p.s。：忽略错误的clusterbinding策略错误，问题已知并且不会影响您登录。</ p>

用户＆＃34;系统＆＃34;无法列出群集中的所有服务
