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 ECS 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:
{
  "family": "logzio-fargate-task",
  "requiresCompatibilities": [ "FARGATE" ],
  "containerDefinitions": [
    {
      "name": "logzio-log-router",
      "image": "amazon/aws-for-fluent-bit:latest",
      "essential": true,
      "firelensConfiguration": {
        "type": "fluentbit",
        "options": { "enable-ecs-log-metadata": "true" }
      },
      "logConfiguration": {
        "logDriver": "awslogs",
        "options": {
          "awslogs-group": "/aws/ecs/logzio-fargate-logs",
          "awslogs-region": "<<AWS-REGION>>",
          "awslogs-stream-prefix": "aws/ecs"
        }
      }
    },
    {
      "name": "app",
      "essential": true,
      "image": "<<YOUR-APP-IMAGE>>",
      "logConfiguration": {
        "logDriver": "awsfirelens",
        "options": {
          "Name": "Http",
          "Host": "<<LISTENER-HOST>>",
          "URI": "/?token=<<LOG-SHIPPING-TOKEN>>&type=fargate",
          "Port": "8071",
          "tls": "on",
          "tls.verify": "off",
          "Format": "json_lines"
        }
      }
    }
  ],
  "cpu": "256",
  "executionRoleArn": "arn:aws:iam::<<AWS-ACCOUNT-ID>>:role/logzioEcsTaskExecutionRole",
  "memory": "512",
  "volumes": [ ],
  "placementConstraints": [ ],
  "networkMode": "awsvpc",
  "tags": [ ]
}

When you’re done, click Save, and then click Create.

Parameters in logzio-log-router
Parameter Description
logConfiguration.options.awslogs-group In the CloudWatch left menu, select Logs > Log groups, and then click Actions > Create log group. Give the Log Group Name /aws/ecs/logzio-fargate-logs.
logConfiguration.options.awslogs-region The AWS region of your cluster.
Parameters in app
Parameter Description
image Replace <<YOUR-APP-IMAGE>> with the name of the image you want to ship logs from.
logConfiguration.options.Host Use the listener URL specific to the region where your Logz.io account is hosted. Click to look up your listener URL. The required port depends whether HTTP or HTTPS is used: HTTP = 8070, HTTPS = 8071. Replace <<LISTENER-HOST>> with the host for your region. For example, listener.logz.io if your account is hosted on AWS US East, or listener-nl.logz.io if hosted on Azure West Europe. The required port depends whether HTTP or HTTPS is used: HTTP = 8070, HTTPS = 8071.
logConfiguration.options.URI Your Logz.io account token. Replace <<LOG-SHIPPING-TOKEN>> with the token of the account you want to ship to.
Remaining parameters
Parameter Description
executionRoleArn Replace <<AWS-ACCOUNT-ID>> with your AWS account Id.
Run the task on your cluster

Go back to your new task’s definition page, and click Actions > Run Task.

Click Switch to launch type, and fill in these details:

  • For Launch Type, select FARGATE.
  • For Cluster, select your cluster.
  • For Subnets, select a subnet from your cluster.

Click Run task.

The logs created by the Fluent Bit shipper are in Cloudwatch under the /aws/ecs/logzio-fargate-logs log group.

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.

Adding extra configuration to your Fluent Bit task

Create an extra.conf file

Create an extra.conf file with the extra configuration. For example:

[FILTER]
    Name record_modifier
    Match *
    Record app-version ${APP_VERSION}
Upload the extra.conf file to S3 (if your Fluent Bit is on EC2)

Upload the extra.conf file to the S3 bucket.

Update the task definition file

Add the path to the extra.conf file to the task definition file as follows:

"firelensConfiguration": {
				"type": "fluentbit",
				"options": {
					"config-file-type": "s3",
					"config-file-value": "arn:aws:s3:::<<PATH-TO-YOUR-EXTRA-CONF>>/extra.conf"
				}
			}

Replace <<PATH-TO-YOUR-EXTRA-CONF>> with the path to the extra.conf file in your S3 bucket. For example, yourbucket/yourdirectory/extra.conf.
