Kubernetes部署gitea
Kubernetes部署代码仓库Gitea
Gitea 是一个开源社区驱动的轻量级代码托管解决方案，周末抽空在Kubernetes部署代码仓库Gitea，过程虽然有些坑，但是最后还是成功在Kubernetes上部署运行，今天将这个过程分享给大家，有需要可以参考。
1、设置持久卷
我们先创建一个持久卷配置，空间大小给5个G，持久卷名字为gitea-pvc
apiVersion: v1 kind: PersistentVolumeClaim metadata: name: gitea-pvc spec: storageClassName: openebs-hostpath accessModes: - ReadWriteOnce resources: requests: storage: 5Gi
2、部署容器
我们设置容器名为gitea-deployment，期望副本为1，同时gitea默认监听端口3000以及需要ssh端口22，我们这里容器监听3000、22端口，设置持久卷目录为/home/storageVolume/gitea。
apiVersion: apps/v1 kind: Deployment metadata: name: gitea-deployment labels: app: gitea spec: replicas: 1 selector: matchLabels: app: gitea template: metadata: labels: app: gitea spec: containers: - name: gitea image: gitea/gitea ports: - containerPort: 3000 name: gitea-http - containerPort: 22 name: gitea-ssh volumeMounts: - mountPath: /home/storageVolume/gitea name: gitea-data volumes: - name: gitea-data persistentVolumeClaim: claimName: gitea-pvc
3、部署服务
我们部署gitea服务，设置服务名为gitea-service，端口监听方式为LoadBalancer，方便IP流量转发到服务上。
LoadBalancer 服务是暴露服务到 internet 的标准方式。在 GKE 上，这种方式会启动一个 Network Load Balancer，它将给你一个单独的 IP 地址，转发所有流量到你的服务。
kind: Service apiVersion: v1 metadata: name: gitea-service annotations: metallb.universe.tf/address-pool: default spec: selector: app: gitea type: LoadBalancer ports: - name: gitea-http port: 3000 targetPort: gitea-http - name: gitea-ssh port: 22 targetPort: gitea-ssh
4、Ingress设置访问域名
为了避免使用ip+port的形式访问gitea，我们利用Ingress设置域名来访问我们的服务，为了防止在初始化安装的时候超时，我们需要设置超时限制，避免安装过程中因为超市失败。
apiVersion: networking.k8s.io/v1beta1 kind: Ingress metadata: name: gitea-ingress annotations: nginx.ingress.kubernetes.io/proxy-body-size: "100m" nginx.ingress.kubernetes.io/proxy-read-timeout: "600" nginx.ingress.kubernetes.io/proxy-send-timeout: "600" nginx.ingress.kubernetes.io/rewrite-target: / nginx.ingress.kubernetes.io/load-balance: "ip_hash" nginx.ingress.kubernetes.io/upstream-hash-by: "$request_uri" spec: rules: - host: gitea.test.cn http: paths: - path: / backend: serviceName: gitea-service servicePort: 3000
5、整合配置
为了方便配置的管理跟部署，我们将上面全部配置整合在一起，命名一个文件为gitea-deployment.yaml，配置如下
apiVersion: v1 kind: PersistentVolumeClaim metadata: name: gitea-pvc spec: storageClassName: openebs-hostpath accessModes: - ReadWriteOnce resources: requests: storage: 5Gi --- apiVersion: apps/v1 kind: Deployment metadata: name: gitea-deployment labels: app: gitea spec: replicas: 1 selector: matchLabels: app: gitea template: metadata: labels: app: gitea spec: containers: - name: gitea image: gitea/gitea ports: - containerPort: 3000 name: gitea-http - containerPort: 22 name: gitea-ssh volumeMounts: - mountPath: /home/storageVolume/gitea name: gitea-data volumes: - name: gitea-data persistentVolumeClaim: claimName: gitea-pvc --- kind: Service apiVersion: v1 metadata: name: gitea-service annotations: metallb.universe.tf/address-pool: default spec: selector: app: gitea type: LoadBalancer ports: - name: gitea-http port: 3000 targetPort: gitea-http - name: gitea-ssh port: 22 targetPort: gitea-ssh --- apiVersion: networking.k8s.io/v1beta1 kind: Ingress metadata: name: gitea-ingress annotations: nginx.ingress.kubernetes.io/proxy-body-size: "100m" nginx.ingress.kubernetes.io/proxy-read-timeout: "600" nginx.ingress.kubernetes.io/proxy-send-timeout: "600" nginx.ingress.kubernetes.io/rewrite-target: / nginx.ingress.kubernetes.io/load-balance: "ip_hash" nginx.ingress.kubernetes.io/upstream-hash-by: "$request_uri" spec: rules: - host: gitea.test.cn http: paths: - path: / backend: serviceName: gitea-service servicePort: 3000
我们输入以下命令行来部署服务
kubectl apply -f gitea-deployment.yaml
等待部署完成后我们直接访问设置的域名，配置参数按照自己的实际情况填就可以。
这样我们就成功完成gitea部署运行。
