ruby-on-rails - CircleCI 连接上的 Rails Fake-S3 被拒绝

Question

我正在尝试按照 this gist 使用 Paperclip 配置 Fake-S3 。在开发机器上一切正常，但是当我尝试在 CircleCI 上运行它时出现错误

Errno::ECONNREFUSED: Connection refused - connect(2) for "local-bucket.local.s3.endpoint" port 4567

我有下一个 config/environments/test.rb:

config.paperclip_defaults = {
  storage: :s3,
  s3_credentials: {
    access_key_id: 'anything',
    secret_access_key: 'anything'
  },
  bucket: 'local-bucket',
  s3_host_name: 'local.s3.endpoint',
  s3_protocol: 'http',
  url: ':s3_alias_url',
  s3_host_alias: 'local-bucket.local.s3.endpoint:4567',
  path: '/test/:class/:attachment/:id_partition/:style/:filename',
  s3_options: {
    use_ssl: false,
    s3_port: 4567
  }
}

在 CircleCI 上，我将该行添加到/etc/hosts:

127.0.0.1 local-bucket.local.s3.endpoint

并运行下一个命令:

fakes3 -r ./fakes3 -p 4567 >log/fakes3.log 2>&1 &

所以，当我尝试使用下一个代码创建新存储桶时:

  s3 = AWS::S3.new(
    access_key_id:     'anything',
    secret_access_key: 'anything',
    s3_endpoint:       'local.s3.endpoint',
    s3_port:           4567,
    use_ssl:           false
)
s3.buckets.create('local-bucket')

我遇到下一个错误:

请帮我找出问题所在？

更新(1):

我意识到，如果我通过 SSH 连接到 CircleCI 构建并运行

fakes3 -r ./fakes3 -p 4567 >log/fakes3.log 2>&1 &

从 Rails 应用程序文件夹中，一切都按需要运行并且所有测试都通过。

更新(2):

circle.yml 文件的一部分:

test:
  pre:
    - bundle exec fakes3 -r ./fakes3 -p 4567 >./log/fakes3.log 2>&1 &
    - bundle exec rake fakes3:create_bucket

Answer 1

经过几天的寻找决定，我找到了。 问题出在使用 & 符号在后台运行 FakeS3

fakes3 -r ./fakes3 -p 4567 >log/fakes3.log 2>&1 &

关注来自 CircleCI 的 this docs:

Starting a background process from circle.yml is entirely possible, but it is not done by adding & to the end of your command line. Instead, you set the background flag on the command.

所以，我重写了 FakeS3 的启动方式:

test:
  pre:
    - bundle exec fakes3 -r ./fakes3 -p 4567 >./log/fakes3.log 2>&1:
        background: true
    - bundle exec rake fakes3:create_bucket

并得到了结果。
