‼️ NOTICE: aws:asset:original-path is non deterministic #17706
Description
What is the problem?
Since 1.134.0, a Function generates the metadata entry aws:asset:original-path which includes the absolute path of the asset to be deployed. This information is system-dependent and therefore results in non-deterministic outputs.
Please add your +1 👍 to let us know you have encountered this
Workaround
Use --no-asset-metadata or set assetMetadata: false in your cdk.json.
Status: IN PROGRESS
Original Issue
Since 1.134.0, a Function is starting to generate the metadata entry aws:asset:original-path which relies on the full path of the asset to be deployed, but the path is definitely depending on the executor environment.
I guess the relating change would be this.
Let's say we defined a Function construct like following:
new lambda.Function(this, 'NiceFunction', {
functionName: 'nice-function',
runtime: lambda.Runtime.RUBY_2_7,
code: lambda.Code.fromAsset(path.join(path.resolve(__dirname, '..'), 'lambda', 'nice_function')),
handler: 'app.LambdaFunctions::NiceFunction.process',
timeout: cdk.Duration.seconds(60),
role: someRole
});Then, if the source script path would be /path/to/my-cdk/lib/my-stack.ts then the aws:asset:original-path would be /path/to/my-cdk/lambda/nice_function.
But when another operator tries to deploy this stack, and if the source script path located on /foo/bar/my-cdk/lib/my-stack.ts then the aws:asset:original-path would claim it as/foo/bar/my-cdk/lambda/nice_function...
So we always face the differences when different operator hits cdk diff and even make a deployment when hitting cdk deploy.
It's very annoying...
Reproduction Steps
Create a stack containing a construct I described in "What is the problem?" section and hit cdk diff.
What did you expect to happen?
No differences appear unless we made changes in the stack.
What actually happened?
So we almost always face the "differences" when different operators hit cdk diff and even make a deployment when hitting cdk deploy.
