Queue

Works with Queue servers.

Testing with a selection of remote/local queueing services, including Amazon's SQS service Iron.io service and beanstalkd service.

Supported and tested queue types are:

The following dependencies are needed for the listed queue servers:

  • Beanstalkd: pda/pheanstalk ~3.0
  • Amazon SQS: aws/aws-sdk-php
  • IronMQ: iron-io/iron_mq

Status

Config

The configuration settings depending on which queueing service is being used, all the options are listed here. Refer to the configuration examples below to identify the configuration options required for your chosen service.

  • type - type of queueing server (defaults to beanstalkd).

  • host - hostname/ip address of the queue server or the host for the iron.io when using iron.io service.

  • port: 11300 - port number for the queue server.

  • timeout: 90 - timeout settings for connecting the queue server.

  • token - Iron.io access token.

  • project - Iron.io project ID.

  • key - AWS access key ID.

  • version - AWS version (e.g. latest)

  • endpoint - The full URI of the webservice. This is only required when connecting to a custom endpoint (e.g., a local version of SQS).

  • secret - AWS secret access key. Warning: Hard-coding your credentials can be dangerous, because it is easy to accidentally commit your credentials into an SCM repository, potentially exposing your credentials to more people than intended. It can also make it difficult to rotate credentials in the future.

  • profile - AWS credential profile - it should be located in ~/.aws/credentials file - eg: [default] aws_access_key_id = YOUR_AWS_ACCESS_KEY_ID aws_secret_access_key = YOUR_AWS_SECRET_ACCESS_KEY [project1] aws_access_key_id = YOUR_AWS_ACCESS_KEY_ID aws_secret_access_key = YOUR_AWS_SECRET_ACCESS_KEY - Note: Using IAM roles is the preferred technique for providing credentials to applications running on Amazon EC2 https://docs.aws.amazon.com/aws-sdk-php/v3/guide/guide/credentials.html?highlight=credentials

  • region - A region parameter is also required for AWS, refer to the AWS documentation for possible values list.

Example

Example (beanstalkd)

modules:
   enabled: [Queue]
   config:
      Queue:
         type: 'beanstalkd'
         host: '127.0.0.1'
         port: 11300
         timeout: 120

Example (Iron.io)

modules:
   enabled: [Queue]
   config:
      Queue:
         'type': 'iron',
         'host': 'mq-aws-us-east-1.iron.io',
         'token': 'your-token',
         'project': 'your-project-id'

Example (AWS SQS)

modules:
   enabled: [Queue]
   config:
      Queue:
         'type': 'aws',
         'key': 'your-public-key',
         'secret': 'your-secret-key',
         'region': 'us-west-2'

Example AWS SQS using profile credentials

modules:
   enabled: [Queue]
   config:
      Queue:
         'type': 'aws',
         'profile': 'project1', //see documentation
         'region': 'us-west-2'

Example AWS SQS running on Amazon EC2 instance

modules:
   enabled: [Queue]
   config:
      Queue:
         'type': 'aws',
         'region': 'us-west-2'
