载波初始化器

CarrierWave.configure do |config|
  config.fog_provider = 'fog/aws'
  config.fog_credentials = {
      provider:              'AWS',
      aws_access_key_id:     'development',
      aws_secret_access_key: 'development',
      region:                'us-east-1',
      host:                  'minio',
      endpoint:              'http://localhost:9000'
  }
  config.fog_directory  = 'test'
  config.fog_public     = false
  # config.fog_attributes = { cache_control: "public, max-age=#{365.day.to_i}" } # optional, defaults to {}
end

Answer 1

在您的情况下，docker 容器内的 Carrierwave 应指向服务 DNS，以下更改应该有效

CarrierWave.configure do |config|
  config.fog_provider = 'fog/aws'
  config.fog_credentials = {
      provider:              'AWS',
      aws_access_key_id:     'development',
      aws_secret_access_key: 'development',
      region:                'us-east-1',
      host:                  'minio',
      endpoint:              'http://minio:9000'
  }
  config.fog_directory  = 'test'
  config.fog_public     = false
  # config.fog_attributes = { cache_control: "public, max-age=#{365.day.to_i}" } # optional, defaults to {}
end

Answer 2

添加到之前的答案中，您还应该将

'path_style' => true

添加到您的配置中

Answer 3

添加到已接受的答案。

path_style

必须添加到fog_credentials中

CarrierWave.configure do |config|
  ...
  config.fog_credentials = {
    ...
    path_style: true
  }
end
