Would like to use a different version of the pulumi-aws package then the one pinned by pulumi-awsx

[lakkeger]

What happened?

Current implementation ignores installed package version and falls back to some hardcoded pulumi-aws version.

Example

Given the below sample project:

import pulumi
import pulumi_aws as aws
import pulumi_awsx as awsx

lb = awsx.lb.ApplicationLoadBalancer("lb")
cluster = aws.ecs.Cluster("cluster")

service = awsx.ecs.FargateService("service",
    cluster=cluster.arn,
    assign_public_ip=True,
    desired_count=2,
    task_definition_args=awsx.ecs.FargateServiceTaskDefinitionArgs(
        container=awsx.ecs.TaskDefinitionContainerDefinitionArgs(
            name="my-service",
            image="nginx:latest",
            cpu=128,
            memory=512,
            essential=True,
            port_mappings=[awsx.ecs.TaskDefinitionPortMappingArgs(
                container_port=80,
                target_group=lb.default_target_group,
            )],
        ),
    ))

pulumi.export("url", pulumi.Output.concat("http://", lb.load_balancer.dns_name))

I ran preview:

$ pulumilocal preview

Additional context

pulumi-local is a thin wrapper for local development on Localstack.
Another issue will be raised regarding the endpoints in the pulumi-aws repo.

Yes, that's a limitation of the current design I believe. We explicitly pin the underlying provider version here: https://github.com/pulumi/pulumi-awsx/blob/master/awsx/package.json#L23C6-L23C6

I can understand the desire to use an alternate version, but there would potentially be some compatibility complications to address.

[lakkeger]

Hi @mjeffryes,
Thanks for clarifying and it would be a nice touch to add the option to change the version.
As a further enhancement could you please add the used dependencies and their version constraints to the docs? As I believe most users' assumption would be that the package uses the locally available packages.

Additionally the aws package until v6.12.0 renders this package unusable to anyone who wish to use the endpoints option.

Also just ran into this issue. Took a while to narrow it down here.

@lakkeger thanks for reporting it. Did you find any way to work around this other than not using pulumi-awsx? I skipped configuring aws:endpoints config and instead configured my AWS profile with endpoint_url but it seems that's getting ignored as well.

[lakkeger]

@mikeshultz Unfortunately no. By being selective with my aws endpoints I could reduce the run time to a reasonable length:

I have some updates on this issue. There are actually two issues: one is being unable to use pulumilocal helper that sets aws:endpoints - the issue persists and still reproduces on awsx 2.10.0 and aws 6.32.0.

    error: pulumi:providers:aws resource 'default_6_32_0' has a problem: `aws:endpoints` is not a valid configuration key for the aws provider. If the referenced key is not intended for the provider, please choose a different namespace from `aws:`.

This is an issue with the pulumi-aws provider. I was able to bisect it and see that it is fixed in v6.36.0.

6.34.0 BAD
6.35.0 BAD
6.36.0 OK

pulumi/pulumi-aws@v6.35.0...v6.36.0

Looking at the diff, it seems that in v6.36.0 endpoints structure received an update to recognize workspacesweb:

    /**
     * @return Use this to override the default service endpoint URL
     *
     */
    public Optional<String> workspacesweb() {
        return Optional.ofNullable(this.workspacesweb);
    }

The good news is that we should be able to release an awsx update shortly that is built against the latest AWS provider and is able to recognize aws:endpoints.

This solution will break again when pulumilocal adds more entries to aws:endpoints and pulumi-aws provider will be lagging behind. There is an issue here I will extract for the pulumi-aws provider to handle this gracefully (both lax parsing and better error reporting).

On the issue as stated, we will have to keep that open; the ability to substitute the underlying provider, currently I am testing transforms workaround but it is not succeeding in fully substitue all the versions of pulumi-aws:

import pulumi
import pulumi_aws as aws
import pulumi_awsx as awsx
from pulumi.runtime import x_register_stack_transform

def aws_provider_version_transform(args: pulumi.ResourceTransformArgs):
    if args.type_.startswith("aws:"):
        print("Transformed ", args.type_)
        return pulumi.ResourceTransformResult(
            props=args.props,
            opts=pulumi.ResourceOptions.merge(args.opts, pulumi.ResourceOptions(
                version="6.36.0",
            ))
        )

x_register_stack_transform(aws_provider_version_transform)

If we cannot make that work perhaps another solution can provide the desired capability.

pulumi/pulumi-aws#4004 relevant issue in pulumi-aws to track the root cause of being unable to use AWSX with newer settings for LocalStack.

Digging a little bit further and getting some help from @justinvp from the core team, there is now a supported way to use a different version of pulumi-aws package with your program. Example:

import pulumi
import pulumi_aws as aws
import pulumi_awsx as awsx

awsp = aws.Provider("awsp", opts=pulumi.ResourceOptions(version="6.36.0"))
lb = awsx.lb.ApplicationLoadBalancer("lb", opts=pulumi.ResourceOptions(providers={"aws": awsp}))

When I run this program, only the desired version of the provider ("6.36.0" in this example) will be used, even if the version of awsx is built against a different aws version ("6.37.1" in my case).

Note that Pulumi currently still may install 6.37.1 version into the plugin cache (pulumi plugin ls), but it will not use it for this program. This can be verified by:

PULUMI_DEBUG_GRPC="$PWD/preview.json" pulumi preview

This also serves as a workaround for the localstack issue - specifying 6.36.0 or higher in this way gets past the problem.
