Chef recipes for Symfony

Recipes

Apache2

• apache2::restart - Restart apache (important to clear the apc cache)

Attributes

• [:apache][:prefork][:maxrequestworkers] - Default is instance memory / 80Mb
• [:apache][:log_filter] - Array of {variable => regex} pairs to filter from logs, defaults:
  • {'User-Agent' => 'ELB-HealthChecker'}
  • {'User-Agent' => 'Amazon Route 53 Health Check Service'}
  • {'Remote_Addr' => '127\.0\.0\.1'}

Files

• files:create - create files in the app directory from JSON (useful for key files etc)

Go Composer

• go-composer - Install composer

Logs

• logs::config - Create config file for CloudWatch logs (Must be done before the daemon is installed)
• logs::setup - Install CloudWatch daemon
• logs::restart - Restart CloudWatch daemon

You will need to give your instances permission to access cloud watch logs, this IAM policy on your instance role should work

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "logs:*"
      ],
      "Resource": [
        "arn:aws:logs:*:*:*"
      ]
    }
  ]
}

Attributes

• [:logs][:apache] - enable sending apache logs to CloudWatch logs
• [:logs][:symfony] - enable sending symfony logs (prod and dev) to CloudWatch logs

Metrics

• metrics::setup - Setup the CloudWatch monitoring - will report disk usage stats

You will need to give your instances permission to access cloud watch, this IAM policy on your instance role should work

• symfony::cron - Create cron jobs for the Symfony commands in JSON
• symfony::ini - php.ini settings
• symfony::logs - Link Symfony log files into the shared logs folder
• symfony::migrate - Run doctrine migrations
• symfony::parameters - Create the Symfony parameters files from JSON
• symfony::permissions - Set permissions on logs and cache so that apache can write to them
• symfony::setup - Install some common php packages

Attributes

• [:symfony][:ini] - PHP ini settings to add
• [:symfony][:console] - The location of the symfony console, default 'app/console'
• [:symfony][:writable] - array of folders that should be writable by the web server, default ['app/cache']
  • {'User-Agent' => 'ELB-HealthChecker'}
  • {'User-Agent' => 'Amazon Route 53 Health Check Service'}
  • {'Remote_Addr' => '127\.0\.0\.1'}

Sample JSON

The top key should match the application name in Opsworks

• parameters - your Symfony parameters file - If a database is attached in Opsworks then the parameters database_* will be set automatically.
• files - the name and content of any files you need to create, file names are relative to the project directory, or start with a /
• crons - the settings for cronjobs that you need to run
  • command - the command and arguments
  • symfony - default true - means you are running a symfony command, it will be run in prod
  • minute - cron format for the time to run at, default *
  • hour - default *
  • day - default *
  • month - default *
  • weekday - default *
• writable - array of directorys that should be writable by apache
• resque - settings for resque - this section must exist for resque to be setup for this app. If this is set then parameters redis_host, redis_port and resque_queue will be set in Symfony
  • workers - number of worker, default node['cpu']['total']
  • queue - queue name, default default, multiple queues can be separated with a comma, and the order that they're supplied in is the order that they're checked in.
  • bin - location of resque commands, default bin/resque
  • scheduler - enable resque_scheduler, default false
  • scheduler_bin - location of scheduler command, default bin/resque_scheduler
  • redis.host - redis host name, default localhost
  • redis.port - redis port, default 6379
  • app_include - defaults to app/bootstrap.php.cache to make sure annotations are loaded an improve load time
  • prefix - set the prefix for all redis keys
  • interval - how long, in seconds, to sleep between jobs, default 5
  • interval_scheduler - how long, in seconds, to sleep between checking for scheduled jobs, default 5
  • blocking - if true the worker uses BLPOP to wait for jobs, and interval is the timeout, default false
• aliases - a set of aliases that you want to setup in your virtual host
