Openshift 3安装问题

Question

我正在Centos 7.8虚拟机上安装Openshift 3.11版集群。配置为有三个Centos虚拟机(一个主节点+两个工作节点)。我也配置了我的清单文件，'prerequisites.yml‘攻略也运行成功。但是当我运行剧本'deploy_cluster.yml‘时，它生成的错误如下

TASK [openshift_version : fail] ***********************************************************************************************************
fatal: [kubernetus]: FAILED! => {"msg": "The conditional check 'not rpm_results.results.package_found' failed. The error was: error while e
valuating conditional (not rpm_results.results.package_found): 'dict object' has no attribute 'results'\n\nThe error appears to be in '/usr
/share/ansible/openshift-ansible/roles/openshift_version/tasks/check_available_rpms.yml': line 8, column 3, but may\nbe elsewhere in the fi
le depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- fail:\n  ^ here\n"}


Failure summary:

     Task:     openshift_version : fail
     Message:  The conditional check 'not rpm_results.results.package_found' failed. The error was: error while evaluating conditional (no$ rpm_results.results.package_found): 'dict object' has no attribute 'results'

The error appears to be in '/usr/share/ansible/openshift-ansible/roles/openshift_version/tasks/check_available_rpms.yml': li
ne 8, column 3, but may

The offending line appears to be:

                 - fail:
                 ^ here

For this, I even checked the corresponding file mentioned above (/usr/share/ansible/openshift-ansible/roles/openshift_version/tasks/check_available_rpms.yml) but could not find anything. Its contents are as follows ---

---
- name: Get available RPM version
  repoquery:
    name: "{{ openshift_service_type }}{% if openshift_version is defined %}-{{ openshift_version }}*{% elif openshift_release is defined %}-{{ openshift_release }}*{% endif %}"
    ignore_excluders: true
  register: rpm_results

- fail:
    msg: "Package '{{ rpm_results.results.package_name }}' not found"
  when: not rpm_results.results.package_found

有没有人可以帮助我，因为我找不到任何解决方案？

Answer 1

从评论中复制(因为这似乎是问题所在)：

因此，repoquery似乎正在寻找"origin-3.11.0*“。当您运行yum search origin-3.11.0*时，输出是什么？我猜这不会找到任何东西，请检查是否附加了正确的YUM存储库。

看起来你在混用OpenShift版本，你已经附加了3.9版本的仓库，但是你正在尝试安装3.11。您需要附加3.11存储库。我建议您参考安装的官方文档：https://docs.okd.io/3.11/install/index.html
