Openshift 3集群安装问题

Question

我正在我的 Centos 7.8 VMS 上安装 Openshift 3.11 版本集群。 配置为3台Centos VM（1个master节点+2个worker节点）。 我还配置了我的库存文件，并且“prerequisites.yml”剧本也成功运行。 但是当我运行剧本'deploy_cluster.yml'时，它会产生如下错误----

[WARNING]: Module invocation had junk after the JSON data: Error in atexit._run_exitfuncs: Traceback (most recent call last):   File
"/usr/lib64/python2.7/atexit.py", line 24, in _run_exitfuncs     func(*targs, **kargs)   File
"/tmp/ansible_oc_obj_payload_A0Bg8i/ansible_oc_obj_payload.zip/ansible/modules/oc_obj.py", line 1257, in cleanup AttributeError:

"/tmp/ansible_oc_obj_payload_A0Bg8i/ansible_oc_obj_payload.zip/ansible/modules/oc_obj.py", line 1257, in cleanup AttributeError:
'NoneType' object has no attribute 'path'

最后，安装程序失败。

为此，我什至检查了 '/var/spool/abrt' 目录，但发现了相同的错误消息 --- 'NoneType' object has no attribute 'path'

我还发现了以下日志----

我无法弄清楚是什么问题？ 有人可以帮我吗？

Answer 1

尝试将您的环境迁移到更高的规格。

尝试为集群机器（Master + Infra 1, Compute 1）使用至少 2vcpu 和 8GB RAM！

Answer 2

如前所述，资源可能是一个问题，还要确保您使用的是与安装程序手册兼容的 ansible 版本
