Hey, I’m quite new to Go and Pulumi. So this is prolly a quite easy question. I’ve been looking into both https://github.com/pulumi/automation-api-examples/blob/main/go/local_program/fargate/main.go and https://www.pulumi.com/docs/reference/pkg/aws/ecs/taskdefinition/#inputs and https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task_definition_parameters.html but I seem to fail miserable anyhow. I’m trying to apply some environment variables and secrets to my container. But I end up getting the following error:

error: aws:ecs/taskDefinition:TaskDefinition resource 'api-task' has a problem: ECS Task Definition container_definitions is invalid: Error decoding JSON: json: cannot unmarshal number into Go struct field KeyValuePair.Environment.Value of type string. Examine values at 'TaskDefinition.ContainerDefinitions'.

So to my understanding is that my type conversion is wrong in some way. Can anybody maybe point me in the right direction or to some example covering how to add the variables. Snippet of my code:

tmpContainerDef, err := json.Marshal([]map[string]interface{}{
			{
				"name":      pulumi.Sprintf("%q", image.ImageName),
				"image":     pulumi.Sprintf("%q", image),
				"cpu":       256,
				"memory":    512,
				"portMappings": []map[string]interface{}{
					{
						"containerPort": 8888,
					},
				},
				"environment": []map[string]interface{}{
					{
						"name": "APP_ENV",
						"value": "prod",
					},
					{
						"name": "API_PORT",
						"value": 8888,
					},
					{
						"name": "DB_DRIVER",
						"value": "postgres",
					},
					{
						"name": "DB_HOST",
						"value": pulumi.Sprintf("%q", dbCluster.Endpoint),
					},
					{
						"name": "DB_NAME",
						"value": pulumi.Sprintf("%q", dbCluster.DatabaseName),
					},
					{
						"name": "DB_USER",
						"value": pulumi.Sprintf("%q", dbCluster.MasterUsername),
					},
					{
						"name": "DB_PORT",
						"value": pulumi.Sprintf("%d", dbCluster.Port),
					},
				},
				"secret": []map[string]interface{}{
					{
						"name": "API_SECRET",
						"valueFrom": pulumi.Sprintf("%q", apiSecret.Arn),
					},
					{
						"name": "DB_PASSWORD",
						"valueFrom": pulumi.Sprintf("%q", dbSecret.Arn),
					},
				},
			},
		})
		if err != nil {
			return err
		}

The ECS JSON takes a string, and the

dbSecret.Arn

is an eventual value, so you'll need to access it via an

ApplyT

Here's an example: https://github.com/jaxxstorm/iac-in-go/blob/fb5eb2c35ed9b4498b35701f3a3e4a43d6c896f7/bastion/main.go#L67-L93

Gotcha. So pretty much like https://github.com/pulumi/automation-api-examples/blob/main/go/local_program/fargate/main.go#L152-L163 Is there a way to run

ApplyT

with several values? Since I need more than just

dbSecret.Arn

as eventual values.

Yes, you can wrap it in

.All

Great! Thx for helping me out @billowy-army-68599! Really appreciate the support 🚀
