Deploying to Fargate but having dedicated ECR per project

[wdolek]

We are hosting our .NET application using AWS Fargate. We build application and build image, and do all setup to deploy it into the cloud.

The main service definition looks like this:

const fargateService = new ecsPatterns.ApplicationLoadBalancedFargateService(
  this,
  "le-app",
  {
    serviceName: "my-app",
    cluster,
    cpu: 512,
    memoryLimitMiB: 1024,
    // ...
    taskImageOptions: {
      image: ecs.ContainerImage.fromAsset("../"),
      containerName: "my-app-container",
      containerPort: 8080,
      family: "appityapp",
      environment: {
        // ...
      },
      secrets: {
        // ...
      },
      // ...
    },
  }
);

Notice taskImageOptions.image. This way, image is created and pushed into CDK assets ECR. Unfortunately, this has several drawbacks:

• it's not possible to tag images nicely
• every CDK deployment to same AWS account / region pushes image to the very same repository

Mainly second reason makes me wonder how I can actually create specific image repository per project, so images are separated. I already spent several hours reading documentation and experimenting with code, but without any success. iirc, this was possible with CDK 1.0, but can't figure it out with current CDK version.

What am I overlooking? Could anyone point me to comprehensive guide covering my use case? (each project - deploy/stack has own ECR, possibility to tag images as I want, e.g. with commit hash from git, build version etc.)
