使用 terraform 安装 Gitlab 时出现 DNS-1035 错误

Question

使用 terraform 安装 gitlab 时出错

错误：服务“test-gitlab.postgres.database.azure.com-headless”无效：metadata.name：无效值：“test-gitlab.postgres.database.azure.com-headless”：DNS- 1035 标签必须由小写字母数字字符或“-”组成，以字母字符开头，并以字母数字字符结尾（例如“my-name”或“abc-123”，用于验证的正则表达式为“az？” )

我正在尝试使用 terraform 安装带有 helm chart 版本 4.4.4 的 Gitlab，当我尝试使用持久性 postgres 数据库安装时，我收到 postgres 主机名的此错误，下面是我的 values.yaml 文件。 如果我不使用持久的 postgres 它可以工作。 错误说标签必须使用小写字符但我只使用小写不知道它为什么会抛出错误。同样在错误“-headless”被添加到我没有从任何地方添加的postgres主机名中，它也会随着构建而变化。

使用的配置

global:
  edition: ce
  psql:
    password:
      secret: gitlabsecret
      key: gitlab-password
    host: test-gitlab.postgres.database.azure.com
    port: 5432
    username: postgres@test-gitlab
    database: postgres

使用的版本

• 图表：4.4.4
• 云：AKS
• Kubernetes：1.10
• 头盔：1.3.2

我通过在 values.yaml 中将 postgres install 显式设置为 false 解决了问题。

global:
  edition: ce
  psql:
    password:
      secret: gitlabsecret
      key: gitlab-password
    host: test-gitlab.postgres.database.azure.com
    port: 5432
    username: postgres@test-gitlab
    database: postgres
postgresql:
  install: false
