I am trying to push an image to ECR and use the image for a fargate service. My project structure is like so

+ infra/
  ++ ecr/
   +++ index.js <-- ecr.Repository & ecs.Image.fromPath
  ++ ecs/
   +++ index.js <-- ecs.FargateService
  ++ index.js <-- main entry point
+ src/
+ Dockerfile

infra/ecr/index.js

var pulumi = require("@pulumi/pulumi");
var awsx = require("@pulumi/awsx");

var ecrRepo = new awsx.ecr.Repository("core", {
  tags: {
    Name: `core ${pulumi.getStack()} repository`,
  },
});
var ecrRepoUrl = ecrRepo.repository.repositoryUrl;

var dockerImage = awsx.ecs.Image.fromPath(ecrRepo, "../../");

module.exports = { ecrRepoUrl, dockerImage };

infra/ecs/index.js

var awsx = require("@pulumi/awsx");

var { loadBalancerListener, securityGroup, vpc } = require("../network");
var { atlasCluster } = require("../mongodb");
var { dockerImage } = require("../ecr");

var { getEnvironmentVariables } = require("./helpers");

var ecsCluster = new awsx.ecs.Cluster("core-cluster", {
  vpc,
  securityGroups: [securityGroup],
});

var fargateService = new awsx.ecs.FargateService("core-fgs", {
  ecsCluster,
  taskDefinitionArgs: {
    container: {
      image: dockerImage,
      cpu: 202,
      memory: 1024,
      portMappings: [loadBalancerListener],
      healthCheck: {
        command: ["CMD-SHELL", "curl -f <http://localhost:3000/> || exit 1"],
        startPeriod: 10,
        retries: 3,
      },
      environment: [
        ...getEnvironmentVariables(),
        {
          name: "DB_CONNECTION_URL",
          value:
            process.env.DB_CONNECTION_URL ||
            atlasCluster.connectionStrings.standardSrv,
        },
      ],
    },
  },
  desiredCount: 1,
});

module.exports = { ecsCluster, fargateService };

infra/index.js

var { ecrRepoUrl, dockerImage } = require("./ecr");
var { fargateService } = require("./ecs");

module.exports = {
  ecrRepositoryUrl: ecrRepoUrl,
  image: dockerImage.environment,
  fargateService: fargateService.urn,
};

When running pulumi I get the following error

Thanks for reporting this. I’ll try to see if I can reproduce with your code.

Life saver! That made it work. Could you please explain a bit of the difference between the awsx and aws when it comes to creating an ECR Repository?

awsx

is a higher-level component library that abstracts away some of the complexities of working with the ‘raw’ AWS resources in

aws

.

awsx

makes various opinionated defaults about how to set things up so you don’t have to think about it. In this case, the

ecs

part of

awsx

was built so that it could interop with any repository (awsx or not), which is why it takes an

aws.ecr.Repository

— probably what could be done to make this even easier is to accept an

awsx.ecr.Repository

object as well and if it gets one of those, just grab the

repository

property from that object. Feel free to file an issue if you think that is a worthwhile ergonomic change.
