1. 项目介绍

项目介绍内容直接贴出官方的,官网的介绍比我介绍的好,直接贴过来了:

twikoo

https://twikoo.js.org/

2. 部署到k8s集群

2.1. 项目分析

  1. 官方提供了docker镜像,可以直接使用
  2. 官方的docker部署命令docker run --name twikoo -e TWIKOO_THROTTLE=1000 -p 8080:8080 -v ${PWD}/data:/app/data -d imaegoo/twikoo,我们进行分析
  3. 需要指定环境变量TWIKOO_THROTTLE和挂载数据卷/app/data
  4. 容器内服务端口为8080

2.2. 配置清单

2.2.1 首先指定命名空间

这里我们直接创建一个twikoo命名空间

apiVersion: apps/v1
kind: Deployment
metadata:
  name: twikoo-deployment
  namespace: twikoo
spec:
  replicas: 1
  selector:
    matchLabels:
      app: twikoo
  template:
    metadata:
      labels:
        app: twikoo
    spec:
      nodeSelector:
        twikoo: enable
      containers:
      - name: twikoo
        image: imaegoo/twikoo
        imagePullPolicy: IfNotPresent
        env:
        - name: TWIKOO_THROTTLE
          value: "1000"
        ports:
        - containerPort: 8080
        volumeMounts:
        - name: data-volume
          mountPath: /app/data
      volumes:
      - name: data-volume
        hostPath:
          path: /mnt/twikoo/data
---
  1. 指定了replicas: 1表示只创建一个pod
  2. app的标签为app: twikoo
  3. 指定了nodeSelector: twikoo: enable表示只在拥有twikoo: enable标签的节点上创建pod
  4. 指定了环境变量TWIKOO_THROTTLE的值为1000
  5. 指定了容器内的端口为8080
  6. 挂载了一个名为data-volume的数据卷,挂载到了容器内的/app/data目录
  7. 指定了hostPath: /mnt/twikoo/data表示将宿主机的/mnt/twikoo/data目录挂载到了data-volume数据卷
  8. 镜像拉取策略为IfNotPresent,表示如果本地没有镜像就拉取,如果有就不拉取

apiVersion: v1
kind: Service
metadata:
  name: twikoo
  namespace: twikoo
spec:
  selector:
    app: twikoo
  ports:
    - name: http
      port: 8080
      targetPort: 8080
  type: ClusterIP
---
  1. 指定了selector: app: twikoo表示将app: twikoo的pod加入到service中
  2. 指定了端口8080
  3. 指定了type: ClusterIP表示创建一个ClusterIP类型的service
  4. ClusterIP类型的service只能在集群内部访问,但我可以配置ingress来让外部访问
  5. ClusterIP类型的service的访问端口为8080
  6. ClusterIP类型的service的访问地址为twikoo.twikoo.svc.cluster.local

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  annotations: {}
  name: twikoo.gucat.vip
  namespace: twikoo
spec:
  ingressClassName: nginx
  rules:
    - host: twikoo.gucat.vip
      http:
        paths:
          - backend:
              service:
                name: twikoo
                port:
                  number: 8080
            path: /
            pathType: Prefix
---
  1. 指定了ingressClassName: nginx表示使用ingress-nginx作为ingress
  2. 配置了host: twikoo.gucat.vip表示访问twikoo.gucat.vip域名时,将请求转发到twikooservice
  3. tls没有配置在这里,我是在ingress-nginx的配置文件中配置的默认证书,该证书是泛域名证书,可以支持所有的子域名

2.3 部署twikoo到k8s集群
