helm 安装gitlab

以下是使用Helm安装GitLab的步骤：

1. 添加GitLab Helm仓库

helm repo add gitlab https://charts.gitlab.io

2. 创建GitLab命名空间

kubectl create namespace gitlab

3. 为GitLab创建一个values.yaml文件，其中包含必要的配置选项。例如：

global:
  edition: ce
  minio:
    enabled: false
  postgresql:
    install: true
    postgresUser: gitlab
    postgresPassword: gitlab
    postgresDatabase: gitlabhq_production
  redis:
    install: true
  certmanager-issuer:
    email: you@example.com
  ingress:
    configureCertmanager: true
    annotations:
      kubernetes.io/ingress.class: nginx
      nginx.ingress.kubernetes.io/proxy-body-size: "0"
      nginx.ingress.kubernetes.io/proxy-read-timeout: "600"
      nginx.ingress.kubernetes.io/proxy-send-timeout: "600"
      nginx.ingress.kubernetes.io/ssl-redirect: "true"
      nginx.ingress.kubernetes.io/force-ssl-redirect: "true"
      nginx.ingress.kubernetes.io/secure-backends: "true"
      nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"
      nginx.ingress.kubernetes.io/proxy-buffering: "on"
      nginx.ingress.kubernetes.io/proxy-buffer-size: "16k"
      nginx.ingress.kubernetes.io/proxy-buffers-number: "4"
      nginx.ingress.kubernetes.io/proxy-request-buffering: "on"
      nginx.ingress.kubernetes.io/proxy-request-buffer-size: "16k"
      nginx.ingress.kubernetes.io/proxy-response-buffering: "on"
      nginx.ingress.kubernetes.io/proxy-response-buffer-size: "16k"
      nginx.ingress.kubernetes.io/proxy-send-timeout: "600"
      nginx.ingress.kubernetes.io/proxy-read-timeout: "600"
      nginx.ingress.kubernetes.io/proxy-connect-timeout: "75"
      nginx.ingress.kubernetes.io/proxy-next-upstream: "error timeout invalid_header http_500 http_502 http_503 http_504"
      nginx.ingress.kubernetes.io/rewrite-target: /$2
      nginx.ingress.kubernetes.io/configuration-snippet: |
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;

        proxy_set_header X-Forwarded-Ssl on;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_http_version 1.1;
        client_max_body_size 0;
        chunked_transfer_encoding on;
  gitlab:
    webservice:
      ingress:
        enabled: true
        annotations:
          nginx.ingress.kubernetes.io/ssl-redirect: "true"
          nginx.ingress.kubernetes.io/force-ssl-redirect: "true"
          nginx.ingress.kubernetes.io/rewrite-target: /$2
          nginx.ingress.kubernetes.io/configuration-snippet: |

            proxy_set_header X-Forwarded-Proto $scheme;

            proxy_set_header X-Forwarded-Ssl on;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
            proxy_http_version 1.1;
            client_max_body_size 0;
            chunked_transfer_encoding on;
        hosts:
          - host: gitlab.example.com
            paths:
              - path: /gitlab(/|$)(.*)
                backend:
                  serviceName: gitlab-webservice
                  servicePort: http

4. 安装GitLab

helm upgrade --install gitlab gitlab/gitlab \
  --namespace=gitlab \
  --set gitlab-runner.install=true \
  --set gitlab-runner.certsSecretName=gitlab-runner-certs \
  --reuse-values \
  -f values.yaml

请注意，这里的values.yaml文件中的配置选项仅供参考，您需要根据自己的需求进行修改。
