Kubernetes Cilium网络组件和CoreDNS配置

1.部署helm网络组件

wget https://mirrors.huaweicloud.com/helm/v3.15.2/helm-v3.15.2-linux-amd64.tar.gz

tar -zxvf helm-v3.15.2-linux-amd64.tar.gz
cp linux-amd64/helm /usr/bin/

# helm version 
version.BuildInfo{Version:"v3.15.2", GitCommit:"1a500d5625419a524fdae4b33de351cc4f58ec35", GitTreeState:"clean", GoVersion:"go1.22.4"}

 

2.添加cilium安装源并下载安装包

# 添加安装源
helm repo add cilium https://helm.cilium.io

# 下载安装包,运行pull命令后会获得最新版cilium的tar包
helm pull cilium/cilium
tar -xvf cilium-*.tar

# 修改image为国内源
sed -i "s#quay.io/#m.daocloud.io/quay.io/#g" cilium/values.yaml

 

3 在master节点上安装cilium

# helm install cilium ./cilium/ \
--namespace kube-system \
--set hubble.relay.enabled=false \
--set hubble.ui.enabled=false \
--set prometheus.enabled=true \
--set operator.prometheus.enabled=true \
--set hubble.enabled=true \
--set hubble.metrics.enabled="{dns,drop,tcp,flow,port-distribution,icmp,http}"
注：如需开启IPv6可添加--set ipv6.enabled=true参数

 

4 查看pod以及crd

# kubectl get apiservices.apiregistration.k8s.io
NAME                                    SERVICE   AVAILABLE   AGE
v1.                                     Local     True        136d
v1.admissionregistration.k8s.io         Local     True        136d
v1.apiextensions.k8s.io                 Local     True        136d
v1.apps                                 Local     True        136d
v1.authentication.k8s.io                Local     True        136d
v1.authorization.k8s.io                 Local     True        136d
v1.autoscaling                          Local     True        136d

 

 

5 在master节点，上将hubble-ui修改为NodePort访问

# kubectl edit svc hubble-ui -n kube-system

# kubectl get svc -A | grep hubble
kube-system         hubble-metrics   ClusterIP   None           <none>        9965/TCP                 5h1m
kube-system         hubble-peer      ClusterIP   10.66.180.91   <none>        443/TCP                  5h1m
kube-system         hubble-relay     ClusterIP   10.66.79.186   <none>        80/TCP                   5h1m
kube-system         hubble-ui        NodePort    10.66.91.101   <none>        80:32093/TCP
