# Ruby APM with AWS Fargate

This document details how to install the **Ruby APM Profiler** in your **Ruby** application running on **AWS Fargate**.

**Stackify** supports **AWS Fargate** by adding our **Retrace Container** to your **AWS Fargate** tasks.

![aws-fargage-diagram](https://cdn.document360.io/3fcaf473-a1ef-4778-aa2c-fd28411c2b01/Images/Documentation/aws-fargage-diagram.png)

The configuration is in two parts; adjusting your **Dockerfile** config to include the appropriate Stackify profiler and then adjusting task/container definition configuration in **AWS Fargate**. The configuration details are provided below in JSON samples.

## Ruby Application Setup

### Add Stackify APM Module

Modify application `Gemfile`:

```
gem 'stackify-ruby-apm'
```

### Configure Application

Add `config/stackify_apm.yml` to your application, modify **application_name** and **environment_name**.

```
application_name: 'Ruby Application'
environment_name: 'Production'
```

#### Rails

Profiler will startup automatically, no additional configuration.

#### Non-Rails

Include **StackifyRubyAPM::Middleware** when starting your application:

```
# config.ru

require 'stackify-ruby-apm'
use StackifyRubyAPM::Middleware
StackifyRubyAPM.start

# application startup

at_exit { StackifyRubyAPM.stop }
```

## Task Configuration

1. Add the **stackify** volume to the **task definition**:

```
{
  "volumes": [
    {
      "name": "stackify"
    }
  ]
}
```

1. Add the **stackify-retrace**  container  to the **task definition**:

```
{
 "containerDefinitions": [
   {
     "name": "stackify-retrace",
     "image": "stackify/retrace:latest",
     "memoryReservation": "512",
     "essential": true,
     "environment": [
       {
         "name": "STACKIFY_KEY",
         "value": "[YOUR_ACTIVATION_KEY]"
       },
       {
         "name": "STACKIFY_ENV",
         "value": "[YOUR_ENVIRONMENT_NAME]"
       }, 
        {
         "name": "STACKIFY_DEVICE_ALIAS",
         "value": "AWS Fargate"
       }
     ],
     "mountPoints": [
       {
         "sourceVolume": "stackify",
         "containerPath": "/var/stackify"
       }
     ]
   }
 ]
}
```

**Note:** Replace `[YOUR_ACTIVATION_KEY]` and `[YOUR_ENVIRONMENT_NAME]`. Use Image `stackify/retrace-arm64` if running on an ARM processor.

1. Add **stackify mount points** to your application **container definition**:

```
{
  "containerDefinitions": [
    {
      "mountPoints": [
        {
          "sourceVolume": "stackify",
          "containerPath": "/usr/local/stackify"
        }
      ]
    }
  ]
}
```

## Verify

Start up your **Ruby** application task and make requests. You can then verify results in the Retrace dashboard.
