红帽全球峰会8.2. 本地访问 kubeconfig 文件
本地访问 kubeconfig 文件被写入 /var/lib/microshift/resources/kubeadmin/kubeconfig。此 kubeconfig 文件通过使用 localhost 提供对 API 服务器的访问。当您在本地连接节点时，选择此文件。
用于本地访问的 kubeconfig 内容示例
clusters:
- cluster:
certificate-authority-data: <base64 CA>
server: https://localhost:6443
clusters:
- cluster:
certificate-authority-data: <base64 CA>
server: https://localhost:6443
localhost kubeconfig 文件只能从从同一主机连接到 API 服务器的客户端中使用。文件中的证书不适用于远程连接。
8.2.1. 在本地访问 MicroShift 节点
复制链接链接已复制到粘贴板!
使用以下步骤，使用 kubeconfig 文件在本地访问 MicroShift 节点。
先决条件
-
已安装 OpenShift CLI (
oc)。
流程
可选：如果您的 Red Hat Enterprise Linux (RHEL)机器没有
~/.kube/文件夹，请运行以下命令：mkdir -p ~/.kube/
$ mkdir -p ~/.kube/Copy to Clipboard Copied! Toggle word wrap Toggle overflow 运行以下命令，将生成的本地访问
kubeconfig文件复制到~/.kube/目录中：sudo cat /var/lib/microshift/resources/kubeadmin/kubeconfig > ~/.kube/config
$ sudo cat /var/lib/microshift/resources/kubeadmin/kubeconfig > ~/.kube/configCopy to Clipboard Copied! Toggle word wrap Toggle overflow 运行以下命令更新
~/.kube/config文件的权限：chmod go-r ~/.kube/config
$ chmod go-r ~/.kube/configCopy to Clipboard Copied! Toggle word wrap Toggle overflow
验证
输入以下命令验证 MicroShift 是否正在运行：
oc get pods -A
$ oc get pods -ACopy to Clipboard Copied! Toggle word wrap Toggle overflow 输出示例
Copy to Clipboard Copied! Toggle word wrap Toggle overflow 注意这个示例输出显示基本的 MicroShift 安装。如果安装了可选的 RPM，则输出中也会期望运行这些服务的 pod 的状态。
