ECS

CatalogDiscovery

Summary

ECS is a fully managed container orchestration service that makes it easy for you to deploy, manage, and scale containerized applications. You can use ECS to drive insights into values such as:

• Service Discovery
• Deployment, container, and events details

Setup

In order to connect Cortex to your AWS resources, you’ll need to add your AWS Account ID and IAM Role in Settings → AWS.

caution

If you do not see the Settings page you're looking for in the sidebar, you likely don't have the proper permissions and need to contact your admin.

1. Log onto the AWS management console and navigate to IAM
2. Create a new IAM policy by navigating to Policies | Create Policy.
3. Switch to the JSON editor and insert the following policy:

   {
     "Version":"2012-10-17",
     "Statement": [
       {
         "Action": [
           "ecs:Describe*",
           "ecs:List*",
           "rds:Describe*",
           "rds:List*",
           "s3:Describe*",
           "s3:List*",
           "s3:GetBucketLocation",
           "s3:GetBucketTagging"
         ],
         "Effect":"Allow",
         "Resource":"*"
       }
     ]
   }
4. Click Review Policy, name it whatever you like, then Create Policy.

Registration

Catalog Descriptor

Cortex uses a combination of Service ARN and Cluster ARN to look up catalog entities in your AWS account. You can tie multiple ECS services to a single entity within Cortex.

x-cortex-infra:
  aws:
    ecs:
      - clusterArn: abcd
        serviceArn: efgh
      - clusterArn: stuv
        serviceArn: wxyz

The value for clusterArn and serviceArn are defined in ECS.
