openshift - 尝试在气隙或断开连接的环境 (RHEL 7.4) 中安装 OKD 3.11 时出错

问题描述

作为在 RHEL-7.4 上运行的本地虚拟服务器上设置 OKD 3.11 的一部分，那里面临以下错误。作为安装的一部分安装了必要的 rpm 包（例如：Ansible Playbooks）。OKD 3.11 安装文件是从 Github 存储库中检索到的，地址为 https://github.com/openshift/openshift-ansible/tree/release-3.11

解决方案

您应该在部署 OKD 3.11 之前安装 epel：

sudo yum -y install epel-release

可能是您在防火墙后面，并且无法访问该站点https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
