接着上文，排除故障后，我重新配置了metallb组件到k8s环境。
metallb为k8s service 的loadbalance负载方式提供免费的解决方案。
external-ip的收费方案，可以选择GRE或Azure，或其他国内云商LB方案。
以下是详细安装和配置步骤:
root >> kubectl apply -f - << EOF
apiVersion: v1
kind: ConfigMap
metadata:
namespace: metallb-system
name: config
data:
config: |
peers:
# Cosmetic edit to make MetalLB notice that this is a new config.
- my-asn: 64512
peer-asn: 64512
peer-address: 10.4.0.100
- my-asn: 64512
peer-asn: 64512
peer-address: 10.4.0.101
- my-asn: 64512
peer-asn: 64512
peer-address: 10.4.0.102
address-pools:
- name: my-ip-space
protocol: bgp
avoid-buggy-ips: true
addresses:
- 10.5.0.0/24
# 执行完毕如下图
