this is indeed part of the

Image

resource: https://github.com/pulumi/pulumi-awsx/blob/ec3ee6d18087f1ac94bde9c609aadbf3ae9e4792/awsx/ecr/image.ts#L70 I guess it’s possibly localstack doesn’t support

getCredentials

?

I'll look into localstack and report back...

i don’t think it’s awsx specific, the underlying call is just a standard pulumi

get

. You can double check by running it outside the component, do you get the same behaviour?

ecr.getCredentials

shows up 4 times in all of github: https://github.com/search?q=ecr.getCredentialsOutput&type=code When you suggest

running it outside the component

, I'm not sure what that means.

aws.ecr.GetCredentials

is a pulumi specific call to retrieve credentials so it won’t show up elsewhere. When I say outside of the component, just make the call directly from your

__main__.py

aws.ecr.get_credentials

instead of

image = awsx.ecr.Image(
    resource_utils.get_name(awsx.ecr.Image),
    repository_url=repo.url,
    path=os.path.join(os.path.dirname(__file__), "..", "..", "docker", "_build"),
)

@billowy-army-68599 So running this

pulumilocal up

on this gives the same error:

invocation of aws:ecr/getCredentials:getCredentials returned an error: error reading from server: EOF

Code

import pulumi_awsx as awsx
import pulumi_aws as aws
from utils import resource_utils

# create an ecr repository in aws
repo = awsx.ecr.Repository(
    resource_utils.get_name(awsx.ecr.Repository),
    tags=resource_utils.tags(),
)

gcr = aws.ecr.get_credentials(registry_id=repo.repository.id)
print(f"gcr=${gcr}")

Error

yeah, looks like localstack doesn’t support returning credentials from its ECR resource 😞

@billowy-army-68599 yeah, my quick perusal of the localstack code base make me wonder how this could work. The only related code I can find for

ecr

is here: https://github.com/localstack/localstack/blob/0221d2908307c2b00e91336aa07e608669341788/localstack/services/cloudformation/models/ecr.py#L14

# TODO: might make sense to limit this only for resources with logical id "ContainerAssetsRepository"
class ECRRepository(GenericBaseModel):
    """
    This is a mock repository to support modern CDK bootstrapping templates.
    It is not intended to be used with other ECR resources.
    """

From this commit: https://github.com/localstack/localstack/commit/0221d2908307c2b00e91336aa07e608669341788 I think, for our use case,

localstack

is not going to work. Bummer, b/c that would have been really cool.
