[英]GitHub Actions: How to connect to Postgres in GithHub Actions
I am trying GitHub Actions for CI with a Ruby on Rails application.我正在使用 Ruby on Rails 应用程序尝试 GitHub Actions for CI。
My setup is with VM, not running the Ruby build in a container.我的设置是使用 VM,而不是在容器中运行 Ruby 构建。
This is my workflow yml.这是我的工作流程 yml。 It runs all the way without errors until the step "Setup Database".
它一直运行而没有错误,直到步骤“设置数据库”。

gem install bundler -v 1.17.3 --no-document
bundle install --jobs 4 --retry 3
npm install
npm install -g yarn
- name: Run rubocop
run: bundle exec rubocop
- name: Run brakeman
run: bundle exec brakeman
- name: Setup Database
env:
RAILS_ENV: test
POSTGRES_HOST: localhost
POSTGRES_USER: postgres
POSTGRES_PASSWORD: postgres
POSTGRES_PORT: ${{ job.services.postgres.ports[5432] }}
run: |
cp config/database.yml.ci config/database.yml
bundle exec rails db:create
bundle exec rails db:schema:load
- name: Run rspec
env:
RAILS_ENV: test
REDIS_HOST: redis
REDIS_PORT: ${{ job.services.redis.ports[6379] }}
POSTGRES_HOST: localhost
POSTGRES_USER: postgres
POSTGRES_PASSWORD: postgres
POSTGRES_PORT: ${{ job.services.postgres.ports[5432] }}
run: bundle exec rspec --tag ~type:system
I am able to install ruby, node, the images, Postgres as a service, etc, and run Rubocop and Brakeman.我能够安装 ruby、节点、图像、Postgres 作为服务等,并运行 Rubocop 和 Brakeman。 But when I try to set up the DB before running Rspec it says it cannot connect to the DB.
但是当我在运行 Rspec 之前尝试设置数据库时,它说它无法连接到数据库。
As far as I've been able to ascertain, the host is localhost when running the VM configuration as opposed to a container configuration.据我所知,在运行 VM 配置而不是容器配置时,主机是 localhost。
This is the database.yml.ci that the "Setup Database" step copies to the database.yml to be used by Rails.这是 database.yml.ci,“Setup Database”步骤复制到 database.yml 以供 Rails 使用。
test:
adapter: postgresql
encoding: unicode
database: db_test
pool: 5
username: <%= ENV['POSTGRES_USER'] %>
password: <%= ENV['POSTGRES_PASSWORD'] %>
host: <%= ENV['POSTGRES_HOST'] %>
I expected Postgres to be correctly set up and bundle exec rails db:create
to create the database.我希望 Postgres 能够正确设置并
bundle exec rails db:create
来创建数据库。 However, it throws the following error:但是,它会引发以下错误:
rails aborted!
PG::ConnectionBad: could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?
I've tried all sorts of different configurations, but unfortunately, Actions is sort of knew and there doesn't seem to be a lot of material available online.我尝试了各种不同的配置,但不幸的是,Actions 有点了解,而且网上似乎没有很多可用的材料。
Any ideas on how to fix this?有想法该怎么解决这个吗?
=========================== ============================
EDIT:编辑:
So I was able to sort this out through trial and error.所以我能够通过反复试验来解决这个问题。 I ended up using a docker image with a ruby and node container.
我最终使用了带有 ruby 和 node 容器的 docker 镜像。 This is the working configuration:
这是工作配置:
on:
push:
branches:
- master
pull_request:
branches:
- master
- development
- release
jobs:
build:
runs-on: ubuntu-latest
container:
image: timbru31/ruby-node:latest
services:
postgres:
image: postgres:11
env:
POSTGRES_USER: postgres
POSTGRES_PASSWORD: postgres
POSTGRES_DB: ci_db_test
ports:
- 5432:5432
options: --health-cmd pg_isready --health-interval 10s --health-timeout 5s --health-retries 5
chrome:
image: selenium/standalone-chrome:latest
ports:
- 4444:4444
steps:
- uses: actions/checkout@v1
- name: Setup app dependencies
run: |
gem install bundler -v 1.17.3 --no-document
bundle install --jobs 4 --retry 3
npm install
npm install -g yarn
- name: Run rubocop
run: bundle exec rubocop
- name: Run brakeman
run: bundle exec brakeman
- name: Setup database
env:
RAILS_ENV: test
POSTGRES_HOST: postgres
POSTGRES_USER: postgres
POSTGRES_PASSWORD: postgres
POSTGRES_DB: ci_db_test
POSTGRES_PORT: ${{ job.services.postgres.ports[5432] }}
run: |
cp config/database.yml.ci config/database.yml
bundle exec rails db:create
bundle exec rails db:schema:load
- name: Run rspec
env:
RAILS_ENV: test
POSTGRES_HOST: postgres
POSTGRES_USER: postgres
POSTGRES_PASSWORD: postgres
POSTGRES_DB: ci_db_test
POSTGRES_PORT: ${{ job.services.postgres.ports[5432] }}
SELENIUM_URL: 'http://chrome:4444/wd/hub'
run: bundle exec rspec
And the CI DB configuration database.yml.ci和 CI DB 配置 database.yml.ci
default: &default
adapter: postgresql
encoding: unicode
username: <%= ENV['POSTGRES_USER'] %>
password: <%= ENV['POSTGRES_PASSWORD'] %>
host: <%= ENV['POSTGRES_HOST'] %>
pool: 5
database: <%= ENV['POSTGRES_DB'] %>
test:
<<: *default
I have a slightly different setup but this was the most relevant question when I encountered the same error so wanted to post here in case it can help.我的设置略有不同,但是当我遇到相同的错误时,这是最相关的问题,因此想在此处发布以防万一。 The two things that were critical for me were: 1) Set the
DB_HOST=localhost
2) Set the --network="host"
argument when you start the docker container with your rails app对我来说至关重要的两件事是:1) 设置
DB_HOST=localhost
2) 在使用 Rails 应用程序启动--network="host"
容器时设置--network="host"
参数
name: Master Build
on: [push]
env:

Your problem appears to be that Postgres is not exposed on port 5432. Try to replace the port number with ${{ job.services.postgres.ports[5432] }}
.您的问题似乎是 Postgres 未在端口
${{ job.services.postgres.ports[5432] }}
上公开。尝试将端口号替换为${{ job.services.postgres.ports[5432] }}
。
There are examples here: https://github.com/actions/example-services/blob/master/.github/workflows/postgres-service.yml这里有例子: https : //github.com/actions/example-services/blob/master/.github/workflows/postgres-service.yml
I had this challenger when trying to set up GitHub actions for a Rails Application.我在尝试为 Rails 应用程序设置 GitHub 操作时遇到了这个挑战者。
Here's what worked for me :这是对我有用的:
name: Ruby
on:
push:
branches:
- main
pull_request:
branches:
- main
jobs:
test:
runs-on: ubuntu-latest
strategy:
matrix:
ruby-version:
- '2.7.2'
node-version:
- '12.22'
database-name:
- my-app
database-password:
- postgres
database-user:
- postgres
database-host:
- 127.0.0.1
database-port:
- 5432
services:
postgres:
image: postgres:latest
env:
POSTGRES_DB: ${{ matrix.database-name }}
POSTGRES_USER: ${{ matrix.database-user }}
POSTGRES_PASSWORD: ${{ matrix.database-password }}
ports:
- 5432:5432
# Set health checks to wait until postgres has started
options:
--health-cmd pg_isready
--health-interval 10s
--health-timeout 5s
--health-retries 5
steps:
- name: Check out Git Repository
uses: actions/checkout@v2
- name: Set up Ruby, Bundler and Rails
uses: ruby/setup-ruby@v1
with:
ruby-version: ${{ matrix.ruby-version }}
bundler-cache: true # runs 'bundle install' and caches installed gems automatically
- name: Set up Node
uses: actions/setup-node@v1
with:
node-version: ${{ matrix.node-version }}
- name: Install packages
run: |
yarn install --check-files
- name: Setup test database
env:
RAILS_ENV: test
DATABASE_NAME_TEST: ${{ matrix.database-name }}
DATABASE_USER: ${{ matrix.database-user }}
DATABASE_PASSWORD: ${{ matrix.database-password }}
DATABASE_HOST: ${{ matrix.database-host }}
DATABASE_PORT: ${{ matrix.database-port }}
POSTGRES_DB: ${{ matrix.database-name }}
run: |
bundle exec rails db:migrate
bundle exec rails db:seed
Note :注意:
my-app
with the name of your app.my-app
替换为您的应用程序名称。database-password
and database-user
as postgres
database-password
和database-user
保留为postgres
That's all.就这样。
I hope this helps我希望这有帮助
