Can't this just be computed based on s3 / code or image?

I mean, you can now end up in a situation where a user will choose a ZIP and an image which isn't correct

(I know there's a validator but why even need it)

What if AWS adds support for another archive type later on? im assuming the API was designed to be open for expansion in the future, we should follow the API. https://www.joelonsoftware.com/2002/11/11/the-law-of-leaky-abstractions/ and such...

Good catch. We typically don't automatically set parameters like this. We should, however, add validation along the lines of:

if package_type is Image, image_uri must be set and none of filename or s3_* can be set

if package_type is Zip, image_uri and image_config cannot be set and either filename or some combination of s3_* must be set

Maybe a good chance to substitute with ExactlyOneOf: []string{"filename", "s3_bucket", "image_uri"} this will save the custom check below.

Good idea. We should probably also set RequiredWith: []string{"s3_key"} on s3_bucket

this doesnt conflict with zip type arguments?

A couple tweaks to the tests

+					testAccCheckResourceAttrRegionalARN(resourceName, "arn", "lambda", fmt.Sprintf("function:%s", funcName)),
+					testAccCheckAwsLambdaFunctionInvokeArn(resourceName, &conf),
+					resource.TestCheckResourceAttr(resourceName, "package_type", lambda.PackageTypeImage),
+					resource.TestCheckResourceAttrSet(resourceName, "image_uri"),


This isn't needed since we're checking the value below

Suggested change

resource.TestCheckResourceAttrSet(resourceName, "image_uri"),

We can check for this to match imageLatestID from above

Suggested change

resource.TestMatchResourceAttr(resourceName, "image_uri", regexp.MustCompile("lambda-image-function:latest$")),

resource.TestCheckResourceAttr(resourceName, "image_uri", imageLatestID),

This change is causing a failure in the test TestAccAWSLambdaFunction_expectFilenameAndS3Attributes

Thanks for the validation suggestions, @stack72 and @DrFaust92. We're going to add those in later so that we can get the container support released today
