几天来，我一直在尝试让 Openshift 在 Vagrant 设置的单个虚拟机上运行，​​并使用 ansible 进行安装。我经历了很多关于 openshift-ansible 的 github 问题，但最后仍然没有运气。这就是我走了多远。所以我从我的 Vagrantfile 开始，并使用 CentosOS/7 作为盒子。由于他们似乎从 xfs 切换了文件系统，这是我遇到的第一个错误，因为 docker 不想工作。所以我查看了 VM-Box Centos 的更新日志，并降级到了 V1804.02。所以这是我现在拥有的 Vagrantfile

因为你会在 SELinux 强制或禁用时遇到错误，这是 SELinux 的配​​置

SELinux 会议

SELINUX=permissive

现在我从清单中的 ansible hosts.localhost 开始。我遇到的第一个错误是关于 docker_image_availability 检查。在 GitHub ppl 上说你应该禁用它。所以这是第一个变化。但是您仍然会通过安装遇到一些问题（错误消息控制平面 pod 没有出现）。因此，下一个更改是根据一些 github 问题将 osm_etcd_image 更改为 osm_etcd_image=registry.access.redhat.com/rhel7/etcd，这让我得到了当前的 ansible hosts 文件

主机

#bare minimum hostfile

[OSEv3:children]

[OSEv3:vars]

osm_etcd_image=registry.access.redhat.com/rhel7/etcd
openshift_deployment_type=origin

openshift_node_groups=[{'name': 'node-config-all-in-one', 'labels': ['node-role.kubernetes.io/master=true', 'node-role.kubernetes.io/infra=true', 'node-role.kubernetes.io/compute=true']}]

172.24.0.11 ansible_connection=local openshift_node_group_name="node-config-all-in-one"

不幸的是，我仍然无法让集群运行，因为它一遍又一遍地重试失败

/bin/oc 获取 pod master-etcd-openshift.example.com -o json -n kube-system"

这似乎拒绝连接并给我留下了这个错误消息

与服务器 openshift.example.com:8443 的连接被拒绝 - 您是否指定了正确的主机或端口？\n"

现在我刚刚发现了一些关于该错误的未解决的 github 问题，最终被卡住了。也许有人知道我做错了什么。

[编辑]

哦，我的任何 etc/hosts 都扩展 172.24.0.11 openshift.example.com 并 ping 172.24.0.11 和 openshift.example.com 成功

值得一提的另一件事是 docker conttainer list -a 还会告诉我一个容器不断尝试重新启动但未能这样做

ab4651c81600 96f98d080ffd "/bin/bash -c '#!/..." 大约一分钟前 Exited (255) 35 秒前 k8s_api_master-api-openshift.example.com_kube-system_fabe879b27fee405485858817f14f32f_9

所以这几乎是本期https://github.com/openshift/openshift-ansible/issues/9894中描述的内容，但是我无法弄清楚我的配置有什么问题

The log of the k8s_api_master container is also not really helping me out

好吧，这花了很多工作，但我终于发现了问题所在。基本上，您的 localhosts 必须指向您在 vagrantfile 中定义的 ip。否则它将无法正常工作。这是在 etc/hosts 中控制的。我也在使用 hawkular 指标。如果你不想你也不需要安装 java-18.0-openjdk-headless
