AWS Fargate is a serverless compute engine for building applications without managing servers. This integration will create a new container that will run your image to send your AWS Fargate logs to Logz.io using FireLens. The integration will automatically create the replica.

Configuration

Build the task execution role

Create a new role in the IAM console.

  • Select AWS service. It should already be selected by default.
  • Under Choose a use case:
    • Select Elastic Container Service
    • Select Elastic Container Service Task (scroll to the bottom of the page to see it.)
    • Click Next: Permissions to continue.
  • Select AmazonECSTaskExecutionRolePolicy.
    • Click Next: Tags and then Next: Review
  • Set Role name to logzioEcsTaskExecutionRole, then click Create role to save.

Your new role should now be created.

  • Click the newly created role to go to its Summary page.
  • Copy the Role ARN (at the top of the page) and save it for later. You will need it for the deployment JSON.
Create a Fluent Bit task definition

In the ECS console, open the Task Definitions page.

  • Select Create new Task Definition.
  • Choose Fargate, and click Next step to continue.
  • Scroll to the bottom of the page to the Volumes section, and select Configure via JSON.
  • Replace the default JSON with this code block:
{

  "requiresCompatibilities": [ "FARGATE" ],
  "containerDefinitions": [
    {
      "name": "logzio-log-router",

Check Logz.io for your logs

Give your logs some time to get from your system to ours, and then open Kibana.

You’ll be able to find these logs by searching for type:fargate.
