Ubuntu oc集群can'；由于缺少~/.kube/config，无法启动kube apiserver

我尝试在我的桌面上运行OKD（Ubuntu 18）。我遵照指示：（）

我已安装Docker：

不安全的注册表：

重新启动Docker deamon：

已禁用防火墙：

下载的OKD客户端工具：

oc

和

kubectl

来自

我尝试启动群集，但失败了

漫长的等待和之后：

E1104 16:59:58.864017    6317 run_self_hosted.go:571] API server error: Get https://127.0.0.1:8443/healthz?timeout=32s: dial tcp 127.0.0.1:8443: connect: connection refused ()
Error: timed out waiting for the condition

---

使用更高的日志级别（我知道我必须删除

openshift.local.clusterup

目录，或者在我想要刷新

oc cluster up

时传递

--base dir

）：

---

我试图检查什么是错误的，我注意到缺少配置的问题

$ ./oc cluster status
Error: invalid configuration: Missing or incomplete configuration info.  Please login or point to an existing, complete config file:

  1. Via the command-line flag --config
  2. Via the KUBECONFIG environment variable
  3. In your home directory as ~/.kube/config

To view or setup config directly use the 'config' command.

我没有环境变量：

$ echo $KUBECONFIG

我没有

~/.kube/config

文件：

$ cat ~/.kube/config
cat: /home/my-username/.kube/config: No such file or directory
$ ls ~/.kube/
ls: cannot access '/home/my-username/.kube/': No such file or directory

我知道，

oc cluster up

应该创建

~/.kube/config

但在我的情况下，它不会产生任何影响。

---

由于缺少配置，即使是

kubectl

也无法工作（我认为它应该可以从二进制文件中使用典型的kubectl安装）：

我解决了这个问题

我有禁用防火墙（ufw）的Ubuntu。但iptables仍然有效

命令

sudo iptables-L

向我显示了许多规则，其中包括以下四条：

Chain KUBE-SERVICES (1 references)
target     prot opt source               destination         
REJECT     tcp  --  anywhere             172.30.237.36        /* default/router:80-tcp has no endpoints */ tcp dpt:http reject-with icmp-port-unreachable
REJECT     tcp  --  anywhere             172.30.1.1           /* default/docker-registry:5000-tcp has no endpoints */ tcp dpt:5000 reject-with icmp-port-unreachable
REJECT     tcp  --  anywhere             172.30.237.36        /* default/router:443-tcp has no endpoints */ tcp dpt:https reject-with icmp-port-unreachable
REJECT     tcp  --  anywhere             172.30.237.36        /* default/router:1936-tcp has no endpoints */ tcp dpt:1936 reject-with icmp-port-unreachable

我不知道他们从哪里来（我可以猜-下面）。我决定删除它

sudo iptables -L --line-numbers
sudo iptables -D KUBE-SERVICES 1
sudo iptables -D KUBE-SERVICES 1
sudo iptables -D KUBE-SERVICES 1
sudo iptables -D KUBE-SERVICES 1

并重新启动系统（确保重新加载iptables）

在

/oc集群启动后

将启动并创建

~/.kube/config

我猜规则可能来自于

oc cluster up

，当我在开始时运行它一次，而不添加

“不安全的注册表”：[“172.30.0.0/16”]

到

/etc/docker/daemon.json

（我试图检查这是否是强制性的）
