Kubernetes之安裝nginx-controller作為統(tǒng)一網(wǎng)關(guān)方式
更新時(shí)間：2024年07月31日 11:27:19 作者：小小白鴿
這篇文章主要介紹了Kubernetes之安裝nginx-controller作為統(tǒng)一網(wǎng)關(guān)方式,具有很好的參考價(jià)值,希望對(duì)大家有所幫助,如有錯(cuò)誤或未考慮完全的地方,望不吝賜教
nginx-controller是什么呢?
- 它是一個(gè)能調(diào)度nginx的一個(gè)kubernetes operator,它能監(jiān)聽用戶創(chuàng)建,更新,刪除NginxConf對(duì)象,來調(diào)度本地的nginx實(shí)現(xiàn)配置的動(dòng)態(tài)更新。如添加新的代理(http,https,tcp,udp),緩存(瀏覽器緩存,本地緩存),ssl證書(配置本身,ConfigMap,Secret),更新,刪除等
- 它使用nginx本身的配置文件(如nginx.conf)來作為配置參數(shù),使nginx配置更透明,易于維護(hù)
安裝之前準(zhǔn)備
- 你得有一個(gè)k8s環(huán)境
- 創(chuàng)建crd
如果你的版本是1.29以下的版本,請(qǐng)刪掉crd里面所有有關(guān)x-kubernetes-validations的部分

---- 執(zhí)行命令,創(chuàng)建crd
kubectl apply -f crd.yaml
- 然后就可以使用
kubectl explain NginxConf查看對(duì)應(yīng)的文檔了，如:
安裝nginx-controller
這里我使用deployment來部署nginx-controller

livenessProbe:

kind: Service
metadata:

namespace: ingress
spec:
selector:
app: ingress
type: NodePort
clusterIP: 10.43.80.80 #這里固定一下ip,方便使用dns指向指定ip,前提是需要安裝dns服務(wù)
ports:
- port: 80
name: http
protocol: TCP
nodePort: 30080
- port: 443
name: https
protocol: TCP
nodePort: 30443然后就可以通過命令看到啟動(dòng)了兩個(gè)容器
由于我本地的環(huán)境和默認(rèn)的不太一樣,所以ip,type可能不相同,但是影響不大,我相信你們也能理解
添加一個(gè)http代理
這里代理百度試試，由于我已經(jīng)安裝了dns服務(wù)，就可以通過域名直接訪問
baidu-nginx-conf.yaml
apiVersion: stable.lhstack.com/v1
kind: NginxConf
metadata:
name: baidu-web
namespace: default #我本地配置監(jiān)聽的是default命名空間
spec:
config: |
server {
server_name baidu.lhstack.com;
listen 80;
gzip on;
gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;
gzip_min_length 1000;
gzip_comp_level 6;
gzip_proxied any;
gzip_vary on;
location / {
proxy_pass https://www.baidu.com;
proxy_http_version 1.1;
}
}可以看到創(chuàng)建成功了，日志也已經(jīng)檢測(cè)到了
現(xiàn)在訪問瀏覽器試試
增加tls證書支持
生成證書
這里我使用cfssl+cfssljson生成證書
- 編寫ca-config.json
{
"signing": {
"default": {
"expiry": "876000h"
},
"profiles": {
"lhstack": {
"expiry": "876000h",
"usages": [
"signing",
"key encipherment",
"server auth",
"client auth"
]
}
}
}
}- 編寫ca-csr.json
{
"CN": "lhstack",
"key#34;: {
"algo": "ecdsa",
"size": 256
},
"names": [
{
"C": "CN",
"ST": "ChengDu",
"L": "ChengDu",
"O":"nginxConf",
"OU":"lhstack"
}
]
}- 生成ca證書
cfssl gencert -initca ca-csr.json | cfssljson -bare ca
- 編寫server-crs.json配置
{
"CN": "lhstack.com",
"hosts":[
"*.lhstack.com"
],
"key": {
"algo": "ecdsa",
"size": 256
},
"names": [
{
"C": "CN",
"ST": "ChengDu",
"L": "ChengDu",
"O":"nginxConf",
"OU":"lhstack"
}
]
}- 生成服務(wù)端證書
cfssl gencert -ca=ca.pem -ca-key=ca-key.pem -config=ca-config.json -profile=lhstack server-csr.json | cfssljson -bare server
瀏覽器導(dǎo)入ca證書
Google瀏覽器 設(shè)置->隱私和安全->安全->管理證書->受信任的根證書頒發(fā)機(jī)構(gòu)->導(dǎo)入->瀏覽->將文件類型選擇為所有類型->選擇ca.pem->導(dǎo)入即可
為代理服務(wù)添加證書
使用Value輸出證書

瀏覽器也不可訪問,變成了我默認(rèn)的服務(wù)

- 更新配置
kubectl apply -f baidu-nginx-conf.yaml
瀏覽器也能正常訪問
如果證書過期了，需要更新證書內(nèi)容怎么辦?
如果使用的ConfigMap,Secret保存的證書,那么就需要手動(dòng)更新ConfigMap,Secret,然后使用以下命令:
觸發(fā)所有NginxConf更新事件
這個(gè)指令會(huì)觸發(fā)所有NginxConf事件,然后走更新流程,就會(huì)拉取最新的ConfigMap,Secret內(nèi)容輸出到指定路徑
kubectl annotate NginxConf --all -A --overwrite updated=$(date +%s)
觸發(fā)一個(gè)NginxConf更新事件
如果已知需要更新的NginxConf配置,則使用此命令觸發(fā)更新事件即可
kubectl annotate -n {命名空間} NginxConf {NginxConf的名稱} --overwrite update=$(date +%s)如果使用的Value輸出,則不需要,因?yàn)関alue本身是NginxConf對(duì)象中的某一個(gè)參數(shù),當(dāng)發(fā)生修改時(shí),kubernetes會(huì)判定為NginxConf發(fā)生了改變,自然而然就會(huì)觸發(fā)更新事件
由于部分圖片違規(guī)，所以對(duì)域名做了遮掩處理，相關(guān)域名通過配置可查看

以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。
