codebuild: ARM images supports all compute types, incorrect validation

[Samrose-Ahmed]

Describe the bug

Theres is an incorrect validation here:

aws-cdk/packages/aws-cdk-lib/aws-codebuild/lib/linux-arm-build-image.ts

Line 115 in 9bd92da

ret.push(`ARM images only support ComputeTypes '${ComputeType.SMALL}' and '${ComputeType.LARGE}' - ` +

that results in error like ARM images only support ComputeTypes 'BUILD_GENERAL1_SMALL' and 'BUILD_GENERAL1_LARGE' - 'BUILD_GENERAL1_XLARGE' was given at PipelineProject.renderEnvironment.

ARM images support all compute types, this is probably outdated.

Expected Behavior

Should support all compute types.

Current Behavior

Only supports small and large.

Reproduction Steps

create codebuild arm project with compute type XLARGE

Possible Solution

Just remove this code:

aws-cdk/packages/aws-cdk-lib/aws-codebuild/lib/linux-arm-build-image.ts

Lines 112 to 116 in 9bd92da

	if (buildEnvironment.computeType &&
	buildEnvironment.computeType !== ComputeType.SMALL &&
	buildEnvironment.computeType !== ComputeType.LARGE) {
	ret.push(`ARM images only support ComputeTypes '${ComputeType.SMALL}' and '${ComputeType.LARGE}' - ` +
	`'${buildEnvironment.computeType}' was given`);

Looks like as of last week ARM expanded to medium Xlarge and 2Xlarge compute types! See the table here.

We should remove the validation, thanks for the call out @Samrose-Ahmed!

Side note: it looks like reserved capacity fleets still have ARM compute types limited to small and large. Best to remove this validation to enable use, but something to keep in mind.

I'd like to work on this issue.

I've removed the code from the "Possible Solution" step. I've also removed the comment above it, suggesting the computeType must be ComputeType.SMALL or ComputeType.LARGE.

How should I be handling the TS warning now that the buildEnvironment variable is no longer being utilized in the validate method?

[scanlonp]

@PeterEckIII, looks like that validate function is specific to ARM build images. Since there are now no restrictions on ARM compute types, the validation may not be necessary at all.

[PeterEckIII]

Thanks @scanlonp, just created #30879 for this. Please let me know of any feedback.

[PeterEckIII]

@scanlonp, I amended my commit with some changes to test files, but it's still denying my PR due to no integration files being changed. I'm looking for any potentially affected files but am slow moving at the moment. If you know any integration files off the top of your head that I can adjust I will make that change. Otherwise, I'll keep digging. Thanks
