I am trying to set up AWS Fargate using Pulumi with a simple flask python app where Dockerfile exposes port 8000, now in the example I could see tht port 80 is mapped in load balancer and later on in taskDefinitionArgs, but how to point it to 8000? I tried this, but doesnt work

// Step 4: Create a Fargate service task that can scale out.

const appService = new awsx.ecs.FargateService("app-svc", {

cluster,

taskDefinitionArgs: {

container: {

image: img,

cpu: 102 /*10% of 1024*/,

memory: 50 /*MB*/,

portMappings: [{ containerPort: 8000, }],

},

},

desiredCount: 5,

});
