如何解决在kubernetes中，我无法访问由MetalLB Loadbalancer分配的externalIP
首先，我在内部使用kubernetes建立集群。
如https://metallb.universe.tf/installation/所示，我按照以下步骤安装了MetalLB，并配置了configmap，部署和服务。
import pandas as pd
import datetime as dt
def getConsecutiveIndexes(series,minimumLength=2,maximumDelta=1):
"""
Return indexes based on Timedeltas's days value consecutively being within a threshold and of a minimum length.
:param pd.Series series: Sorted series containing Timedeltas.
:param minimumLength: Minimum length of list to be returned.
:param maximumDelta: Maximum difference to be considered consecutive.
"""
indexes = []
previousValue = None
for i,timedelta in series.items():
val = timedelta.days
previousValueDelta = 0 if previousValue is None else val - previousValue
isConsecutive = previousValueDelta <= maximumDelta
lastIndex = i == len(series) - 1
if isConsecutive or not indexes:
indexes.append(i)
satisfiedLength = len(indexes) >= minimumLength
if (lastIndex or not isConsecutive) and satisfiedLength:
return indexes
if not isConsecutive:
indexes = [i]
previousValue = val
def createTimedeltaSeries(l):
"""Easily create a series containing Timedeltas."""
return pd.Series([dt.timedelta(days=value) for value in l])
assert [0,1,2,3,4,5,6,7] == getConsecutiveIndexes(createTimedeltaSeries([0,7,9]))
assert [1,2] == getConsecutiveIndexes(createTimedeltaSeries([2,10]))
assert [0,3] == getConsecutiveIndexes(createTimedeltaSeries([2,10]),maximumDelta=2)
assert [2,4] == getConsecutiveIndexes(createTimedeltaSeries([1,6]),minimumLength=3)
configmap.yaml
kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.9.3/manifests/namespace.yaml
kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.9.3/manifests/metallb.yaml
# On first install only
kubectl create secret generic -n metallb-system memberlist --from-literal=secretkey="$(openssl rand -base64 128)"
tutorial.yaml
apiVersion: v1
kind: ConfigMap
metadata:
namespace: metallb-system
name: config
data:
config: |
address-pools:
- name: default
protocol: layer2
addresses:
- 192.168.1.240-192.168.1.250
配置后，当我使用命令apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx
spec:
selector:
matchLabels:
app: nginx
template:
metadata:
labels:
app: nginx
spec:
containers:

containerPort: 80
---
apiVersion: v1
kind: Service
metadata:
name: nginx
spec:
ports:
- name: http
port: 80
protocol: TCP
targetPort: 80
selector:
app: nginx
type: LoadBalancer
检查服务时，有一个带有EXTERNAL-IP的Nginx服务。
kubectl get svc当我输入“ 192.168.143.230”时，我无法访问该页面，并显示以下消息：“无法访问192.168.143.230，此站点花费了很长时间才能响应”。
如何使用EXTERNAL-IP访问该页面？
解决方法
我想它将可以通过192.168.143.230:32190访问
