Github 操作工作流程 PG::ConnectionBad：无法连接到服务器：运行 bundle exec rake 时没有此类文件或目录

Question

这是我的第一个问题。

我正在尝试集成github actions到我的 Rails 项目中。

我的 ruby​​.yml 是这样的：

name: Ruby

on:
  push:
    branches: [ master ]
  pull_request:
    branches: [ master ]

jobs:
  test:

    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v2
    - name: Set up Ruby
      uses: ruby/setup-ruby@ec106b438a1ff6ff112340de34ddc62c540232e0
      with:
        ruby-version: 2.6.5
    - name: Install dependencies
      run: bundle install
    - name: Run tests
      run: bundle exec rake

捆绑步骤需要很多时间，我不知道是否可以只加载 Gemfile.lock 而不是每次都运行捆绑。但运行起来没问题。

问题是测试步骤。

所以这是错误：

rails aborted!
PG::ConnectionBad: could not connect to server: No such file or directory
    Is the server running locally and accepting
    connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

谢谢大家。

您需要将 Postgres 服务添加到 GitHub Action 配置中。例如：

services:
  postgres:
    image: postgres:11
      env:
        POSTGRES_PASSWORD: postgres
        POSTGRES_USER: postgres
      options: --health-cmd pg_isready --health-interval 10s --health-timeout 5s --health-retries 5
      ports:
        - 5432:5432

在bundle install你需要安装依赖库之前：

- name: Install library for postgres
  run: sudo apt-get install libpq-dev

不要忘记设置数据库：

- name: Setup Database
  run: |
    cp config/YOUR_GITHUB_ACTIONS_DATABASE.yml config/database.yml
    bundle exec rails db:setup
  env:
    POSTGRES_PASSWORD: postgres
    POSTGRES_USER: postgres
    RAILS_ENV: test

当然，在这里，您必须根据您的具体情况定制命令。最简单的方法是专门为 GitHub Actions 创建一个单独的数据库配置文件。但你也可以有一个特殊的 CI 环境。
