vmware-archive / chemtrails Goto Github PK

When providing chemtrails with an extra long (read: actually secure) username and password, the gem will fail trying to receive information from the config server.

It gives some cryptic Syntax error: Unterminated quote string error. Upon further investigation, we discovered that it is most likely the gem Excon being used by chemtrails for http interaction with the config server. Using Excon manually with the credentials gets back a 400 Bad Request. Using a username and password with fewer characters fixes this issue.

I didn't check what the length Excon is actually okay with, I just chopped off some characters until it worked. ¯_(ツ)_/¯

Looks like the support of Rails 5.0 was reverted to 4.0, any reasons?

When can it be available for 5.x support?

Hi,

first thanks for this gem, as it had helped us to integrate our rails app into spring cloud config. The thing is that we need to reload ENV vars from SCC while the app is still running.

We are trying to modify the chemtrails railtie to mimic the Spring Cloud Bus (that uses RabbitMQ) to get events of "Configuration changed" with the next snippet

config.before_configuration do
      startup(Rails.application.class.parent.to_s.downcase, Rails.env, ENV) unless Rails.env.test?

      rabbit_host = ENV['rabbit_host']
      rabbit_port = ENV['rabbit_port'] ||
      rabbit_username = ENV['rabbit_username']
      rabbit_password = ENV['rabbit_password']
      rabbit_vhost = ENV['rabbit_vhost'] || '#'

      unless Rails.env.test? || rabbit_host.nil?
        conn = Bunny.new(
          :host => rabbit_host,
          :port => rabbit_port,
          :user => rabbit_username,
          :password => rabbit_password
        )
        conn.start

        ch = conn.create_channel
        q = ch.queue("springCloudBus.anonymous." + Rails.application.class.parent.to_s.downcase + Time.now.to_i.to_s, :auto_delete => true, :exclusive => true)
        q.bind("springCloudBus", :routing_key => "#")

        q.subscribe do |delivery_info, metadata, payload|
          obj = JSON.parse(payload)
          # Only reload the application on events of refresh configurattion
          if obj['type'] == "RefreshRemoteApplicationEvent"
            startup(Rails.application.class.parent.to_s.downcase, Rails.env, ENV)

            puts ENV
          end
        end
      end
    end

And it fetches an populates the ENV with the new configuration but for any reason when we visit any of the http endpoints to check the environment

# frozen_string_literal: true

class EnvController < ApplicationController

  before_action :authenticate_user!

  def index
    render json: ENV
  end

end

The value is the initial value when the application started.

Do you have any hint about what can we do to get this working? Is it possible?
