开放端口，用于在高的农场/ Kubernetes（RKE）内部地址？

Question

我有以下的配置设置使用Rancher (RKE)集群。

牧场主，config.yml

nodes:
  - address: 192.168.88.204
    internal_address: 172.16.22.12
    user: dockeruser
    role: [controlplane,worker,etcd]
  - address: 192.168.88.203
    internal_address: 172.16.32.37
    user: dockeruser
    role: [controlplane,worker,etcd]
  - address: 192.168.88.202
    internal_address: 172.16.42.73
    user: dockeruser
    role: [controlplane,worker,etcd]

services:
  etcd:
    snapshot: true
    creation: 6h
    retention: 24h 

据Rancher Networking，我已经打开以下端口的所有节点（192.168.88.204，192.168.88.203，192.168.88.202）防火墙服务。

节点firewall.xml

<?xml version="1.0" encoding="utf-8"?>
<service>
    <port port="2376" protocol="tcp"/>
    <port port="2379" protocol="tcp"/>
    <port port="2380" protocol="tcp"/>
    <port port="8472" protocol="udp"/>
    <port port="9099" protocol="tcp"/>
    <port port="10250" protocol="tcp"/>
    <port port="443" protocol="tcp"/>
    <port port="6443" protocol="tcp"/>
    <port port="8472" protocol="udp"/>
    <port port="6443" protocol="tcp"/>
    <port port="10254" protocol="tcp"/>
    <port port="30000-32767" protocol="tcp"/>
</service>

-> commmend

firewall-offline-cmd --new-service-from-file=node-firewall.xml --name=node-firewall
firewall-cmd --reload
firewall-cmd --add-service node-firewall

我RKE安装在192.168.88.151。对于RKE - >

rancher-firewall.xml

<?xml version="1.0" encoding="utf-8"?>
<service>
    <port port="80" protocol="tcp"/>
    <port port="433" protocol="tcp"/>
    <port port="22" protocol="tcp"/>
    <port port="2376" protocol="tcp"/>
    <port port="6443" protocol="tcp"/>
</service>
firewall-offline-cmd --new-service-from-file=rancher-firewall.xml --name=rancher-firewall
firewall-cmd --reload
firewall-cmd --add-service rancher-firewall

所以，我运行下面的命令来了我qazxsw POI

RKE

日志

rke up --config ./rancher-config.yml

我的问题是如何打开的端口

[root@localhost ~]# rke up --config ./rancher-config.yml

            Please check network policies and firewall rules

在internal_address集群中所有节点？

Answer 1

可能是缺少我的经验。我只是分享我发现了什么。 kubernates是必须internal_address的（网关）的IP地址。要知道泊坞窗的每个节点（192.168.88.204，192.168.88.203，192.168.88.202）的IP地址。

运行表彰docker。你可能会得到如下的网络信息。

docker network ls

并运行命令qazxsw POI获得qazxsw POI的IP地址。你会得到下面的similer信息。

NETWORK ID          NAME                DRIVER              SCOPE
aa13d08f2676        bridge              bridge              local
02eabe818790        host                host                local
1e5bb430d790        none                null                local

并且如下配置docker network inspect bridge并再次运行bridge

[
    {
        "Name": "bridge",
        "Id": "aa13d08f2676e40df5a82521fccc4e402ef6b04f82bcd414cd065a1859b3799d",
        "Created": "2019-01-31T21:32:02.381082005-05:00",
        "Scope": "local",
        "Driver": "bridge",
        "EnableIPv6": false,
        "IPAM": {
            "Driver": "default",
            "Options": null,
            "Config": [
                {
                    "Subnet": "172.17.0.0/16",
                    "Gateway": "172.17.0.1"
                }
            ]
        },
        ....
        ...
        ..
        .

]

Answer 2

这是不正确。

该internal_address提供有节点具有多个地址设置为专用网络上使用的主机间通信的特定地址的能力。如果没有设置internal_address，该地址用于主机间的通信。

对于rancher-config.yml

你可能有一个防火墙问题。

检查你的活动区域，并在这些区域的哪些接口。

rke up --config ./rancher-config.yml
