Add an SQS Trigger for the queue(s) you want to process jobs from.ĥ. Create a lambda function from your image (see the Lambda docs for details).Ĥ. With Lambda Container Image Support and the lambda handler provided with aws-sdk-rails its easy to use lambda to run ActiveJobs for your dockerized rails app (see below for some tips). Rather than managing the worker processes yourself, you can use Lambda with an SQS Trigger. Serverless workers: processing activejobs using AWS Lambda You can use CTRL+C to cleanly shutdown the poller – it will wait for currently executing jobs to finish before exiting. The poller will poll indefinitely until you kill it. Run the backend poller and execute jobs: RAILS_ENV=development bundle exec aws_sqs_active_job -queue defaultĪt this point you should see output from the jobs you queued up earlier. When running in production, its recommended that use a process supervisor such as foreman, systemd, daemontools, etc. To start processing jobs, you need to start a separate process using an executable script ( bin/aws_sqs_active_job) provided with this gem. t(wait: 5.minutes).perform_later('Person2') Queue up jobs # in your business logic or from rails console Map Rails Queues to your SQS Queue URLs: # config/aws_sqs_active_job.ymlĤ. # for non-blocking (async), use :amazon_sqs_asyncĬonfig.active_job.queue_adapter = :amazon_sqsģ. Configure the queuing backend: # config/application.rb This will generate a job which you can edit: class GreetingJob < ApplicationJobĢ. To use SQS for ActiveJob, you first need to: This gem includes a lightweight, high performance SQS backend for ActiveJob. # Or use a regex to subscribe to all service notificationsĪctiveSupport::Notifications.subscribe(/s3aws/) do |name, start, finish, id, payload| Once done, you can create a subscriber to perform actions when SDK calls are made: ActiveSupport::Notifications.subscribe('put_object.s3.aws') do |name, start, finish, id, payload| From a Rails initializer, you can enable this feature before you construct any SDK clients: # config/initializers/aws.rb You can now instrument AWS SDK service calls using ActiveSupport::Notifications. This table can be created manually, or using the ActiveRecord migration generator included with this gem: rails generate dynamo_db:session_store_migration Active Support Notification Instrumentation for AWS SDK calls You will need to have an existing DynamoDB session table to use this feature. You can configure ActionDispatch::Session storage in Rails to use DynamoDB instead of cookies, allowing access to sessions from other applications and devices. Never commit your credentials to source control. Besides being a security risk, it makes it very difficult to rotate your credentials. You can add them to your Rails encrypted credentials under the :aws key or see the AWS SDK for Ruby Documentation for other ways to configure credentials. You will have to ensure that you provide AWS credentials for the SDK to use. All other features are optional and will require some additional configuration.
