与服务器master.ctwifi.cn:8443的连接被拒绝-您是否指定了正确的主机或端口？\ n“

Question

描述

•   

  CentOS 7.4

•   

  我使用了Ansible安装OpenShift，并且必须使用HTTP_PROXY。

•   

  我有这样一个问题：“ stderr”：“与服务器master.ctwifi.cn:8443的连接被拒绝-您指定了正确的主机还是   端口？\ n“，

•   

  并且主主机上没有8443端口。在主主机上运行的容器数仅为5。我认为kubernetes master尚未启动，但我不知道为什么。

       

  但是我使用相同的配置来安装在公共云上除了代理配置，没有问题。所以我认为这个问题与我的代理配置有关。但是我没有找到解决方法。

  ansible-playbook〜/ openshift-ansible / playbooks / prerequisites.yml -vvv 可以

问题

ansible-playbook〜/ openshift-ansible / playbooks / deploy_cluster.yml -vvv

Answer 1

FAILED - RETRYING: Wait for control plane pods...表示API服务器存在问题。它本身的问题是多种多样的。我没有足够的意见要发表，但我会尽力回答。

有时openshift找不到通往吊舱的路线，如果存在这种情况，那么 在openshift_set_node_ip=true中添加[OSEv3:vars]并将osnode1 openshift_ip=xxx.xxx.xxx.xxx ....放入每个节点。

有时候，如果没有创建用户，就会出现问题，那么您必须添加 openshift_master_htpasswd_users={'admin': '$apr1$RbOvaj8r$LEqJqG6V/O/i7Pf...'}

另外，API和ETCD最好放在不同的位置。

下面是您的清单文件，我做了一些编辑，请看一下：
