Rails Elastic Beanstalk 部署 - sqlite3

Question

我正在尝试将 Rails 应用程序部署到弹性 beanstalk，但出现错误。

INFO: Environment update is starting.

ERROR: Failed to deploy application.

不知道为什么我会收到此载波错误。我有那个文件可以与 S3 一起上传照片。

carrierwave.rb

CarrierWave.configure do |config|
    config.fog_credentials = {
        provider: "AWS",
        aws_access_key_id: ENV["AWS_ACCESS_KEY_ID"],
        aws_secret_access_key: ENV["AWS_SECRET_ACCESS_KEY"]
    }
    config.fog_directory = ENV["AWS_S3_BUCKET"]
end

环境.rb

# Load the Rails application.
require File.expand_path('../application', __FILE__)

# Initialize the Rails application.
Rails.application.initialize!

这是日志：

编辑 这里：

 ArgumentError: Missing required arguments: aws_access_key_id, aws_secret_access_key

EDIT2 我的 gem 文件的一部分；

group :development, :test do
  gem 'sqlite3',     '1.3.9'
  gem 'byebug',      '3.4.0'
  gem 'web-console', '2.0.0.beta3'
  gem 'spring',      '1.1.3'
end

group :test do
  gem 'minitest-reporters', '1.0.5'
  gem 'mini_backtrace',     '0.1.3'
  gem 'guard-minitest',     '2.3.1'
end

group :production do
  gem 'pg',             '0.17.1'
  gem 'rails_12factor', '0.0.2'
end

我用 postgresql 创建了 RDS。 database.yml 文件；

# SQLite version 3.x
#   gem install sqlite3
#
#   Ensure the SQLite 3 gem is defined in your Gemfile
#   gem 'sqlite3'
#
default: &default
  adapter: sqlite3
  pool: 5
  timeout: 5000

development:
  <<: *default
  database: db/development.sqlite3

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  <<: *default
  database: db/test.sqlite3

production:
  <<: *default
  database: <%= ENV['RDS_DB_NAME'] %>#db/production.sqlite3
  username: <%= ENV['RDS_USERNAME'] %>
  password: <%= ENV['RDS_PASSWORD'] %>
  host: <%= ENV['RDS_HOSTNAME'] %>
  port: <%= ENV['RDS_PORT'] %>

得到一个错误;

ERROR: [Instance: i-053f6b1dfef0f156b] Command failed on instance. Return code: 1 Output: (TRUNCATED)...sqlite3'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord).

Gem::LoadError: sqlite3 is not part of the bundle. Add it to Gemfile.

我为什么要添加 gem sqlite3？，我已经在开发中，应该在生产中使用。这就是 Heroku 的工作原理。我对弹性豆茎也有同样的想法

Answer 1

我有同样的问题。我发现了两个问题：

1. 环境中缺少 AWS 环境变量（CarrierWave 需要）（这会在创建过程中阻止 rake assets:precompile）。
2. Gemfile 的生产中缺少 sqlite3（EB 需要）。

创建环境时需要配置AWS环境变量：

eb create [app_name] -v --envvars AWS_ACCESS_KEY_ID=[access_key], AWS_ACCESS_KEY_SECRET=[key_secret]` 

事件虽然你在AWS RDS 中使用PostgreSQL 作为你的数据库，并且你已经在Gemfile 和database.yml 中指定了它，但EB 仍然需要sqlite3。也许是为了自己的用途。所以只需将 sqlite3 添加到 Gemfile 的生产块。

Answer 2

从您的 database.yml 文件中 production: 的第一行中删除 <<: *default。 它会导致你混乱 b/c 在默认情况下你说 sqlite3 然后在接下来的 5 行中你提供 postgres 信息。
