Gitlab-ci.yml rspec迁移到pg后测试错误

Question

我在执行.gitlab-ci.yml时在gitlab上出现错误

$ bundle exec rspec

在.gitlab-ci.yml中

在本地，我有用于开发和测试环境的PostgreSQL。所有rspec测试都通过了。

但是在gitlab上载项目后，它会引发错误：

An error occurred while loading ./spec/requests/api/packages_spec.rb.
Failure/Error: ActiveRecord::Migration.maintain_test_schema!
PG::ConnectionBad:
  could not connect to server: No such file or directory
      Is the server running locally and accepting
      connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"

在我拥有sqlite3数据库之前。但是比我迁移到pg。

database.yml：

default: &default
  adapter: postgresql
  encoding: unicode
  # For details on connection pooling, see Rails configuration guide
  # https://guides.rubyonrails.org/configuring.html#database-pooling
  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>

development:
  <<: *default
  database: pg_app_development

test:
  <<: *default
  database: pg_app_test

Answer 1

添加database.yml端口和主机变量：

test:
  <<: *default
  database: pg_app_test
  user: postgres
  host: <%= ENV.fetch("DATABASE_HOST") { 'localhost' } %>
  port: 5432

和.gitlab-ci.yml的db变量

variables:
    RAILS_ENV: test
    POSTGRES_DB: pg_app_test
    POSTGRES_USER: postgres
    POSTGRES_HOST_AUTH_METHOD: trust
    DATABASE_HOST: postgres
