How to add a policy statement to a ecr repository - aws-cdk

Question

How to add a policy statement to a ecr repository although i know i can add a policy statement but in my case there are multiple statements so i am trying to attach a policy document for which i am getting compilation
Here i am creating a policy document
let policy = new iam.PolicyDocument({
statements: [
new iam.PolicyStatement({
sid: 'CrossAccountPermission',
principals: principalArr,
actions: [
'ecr:BatchCheckLayerAvailability',
'ecr:BatchGetImage',
'ecr:DescribeImages',
'ecr:DescribeRepositories',
'ecr:GetDownloadUrlForLayer',
'ecr:ListImages'
],
}),
//This is the second policy statement
new iam.PolicyStatement({
sid:'LambdaECRImageCrossAccountRetrievalPolicy',
effect: iam.Effect.ALLOW,
principals: lambdaPrincipal,
actions: [
'ecr:BatchGetImage',
'ecr:GetDownloadUrlForLayer'
]
})
]
});
**Here i am creating a repository for using the above policy statement**
const ecrRepo = ecr.Repository.fromRepositoryName(scope, 'repository');
Now there is no method in ecrRepo to add policy document, although there is a method to add policy statement.
Can someone please help me on how do i add multiple statement or policy document to a repo ??

Answer 1

This is how, you can try.
var ecrRepo = Repository.FromRepositoryName(scope, "id", "repositoryName");
foreach (var statement in policyStatements)
{
ecrRepo.AddToResourcePolicy(statement);
}
This is C# code, and I have not tried. But, it should work.
