Configuring an ECS Task Definition in AWS

In this guide, we will configure an AWS ECS Task Definition. The task definition specifies parameters for Docker containers in a cluster. We will set up essential configurations such as container definitions, CPU and memory requirements, and network mode.

Key Points:

• Understand the components of an ECS Task Definition.
• Define a container with its configuration inside the Task Definition.
• Customize CPU, memory, and network requirements.

Below is the program that configures an ECS Task Definition:

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

const example = new aws.ecs.TaskDefinition("example", {
    family: "example",
    networkMode: "awsvpc",
    requiresCompatibilities: ["FARGATE"],
    cpu: "256",
    memory: "512",
    containerDefinitions: JSON.stringify([{
        name: "example",
        image: "nginx:latest",
        essential: true,
        portMappings: [{
            containerPort: 80,
            hostPort: 80,
            protocol: "tcp",
        }],
        logConfiguration: {
            logDriver: "awslogs",
            options: {
                "awslogs-group": "/ecs/example",
                "awslogs-region": "us-west-2",
                "awslogs-stream-prefix": "ecs",
            },
        },
    }]),
});
export const taskDefinitionArn = example.arn;

Concluding Summary:

In this guide, we configured an ECS Task Definition on AWS. Starting with setting up the basic parameters, we included container definitions and critical configurations like CPU, memory, and logging. We then finalized by exporting the Task Definition ARN which can be used to run tasks and services. This will help you efficiently manage and deploy containerized applications on AWS.
