Identity policies
In order to grant access to a repository for read access, the following policy will need to be applied to the AWS identity for which credentials will be used to access the repository.
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"sts:GetServiceBearerToken"
],
"Resource": "*"
},
{
"Effect": "Allow",
"Action": [
"codeartifact:DescribeDomain",
"codeartifact:GetAuthorizationToken",
"codeartifact:ListRepositoriesInDomain"
],
"Resource": "arn:aws:codeartifact:us-east-1:345125489763:domain/my-domain"
},
{
"Effect": "Allow",
"Action": [
"codeartifact:Describe*",
"codeartifact:List*",
"codeartifact:GetPackageVersionReadme",
"codeartifact:GetRepositoryEndpoint",
"codeartifact:ReadFromRepository"
],
"Resource": [
"arn:aws:codeartifact:us-east-1:345125489763:repository/my-domain/my-repo",
"arn:aws:codeartifact:us-east-1:345125489763:repository/my-domain/my-repo/*",
"arn:aws:codeartifact:us-east-1:345125489763:package/my-domain/my-repo/*"
]
}
]
}

In order to grant access to a repository for write access, the following policy will need to be applied to the AWS identity for which credentials will be used to access the repository.
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"codeartifact:GetRepositoryEndpoint",
"codeartifact:PublishPackageVersion",
"codeartifact:PutPackageMetadata"
],
"Resource": [
"arn:aws:codeartifact:us-east-1:345125489763:repository/my-domain/my-repo",
"arn:aws:codeartifact:us-east-1:345125489763:repository/my-domain/my-repo/*",
"arn:aws:codeartifact:us-east-1:345125489763:package/my-domain/my-repo/*"
]
}
]
}

Cross-account policies
For cross-account access to the AWS CodeArtifact domain, the domain must have the resource policy,
{
"Version": "2012-10-17",
"Statement": [
{
"Principal": {
"AWS": "arn:aws:iam::345125489763:root"
},
"Effect": "Allow",
"Action": [
"codeartifact:DescribeDomain",
"codeartifact:GetAuthorizationToken",
"codeartifact:ListRepositoriesInDomain"
],
"Resource": "*"
}
]
}

For cross-account read access to a repository, the repository will require the following resource policy,
{
"Version": "2012-10-17",
"Statement": [
{
"Principal": {
"AWS": "arn:aws:iam::345125489763:root"
},
"Effect": "Allow",
"Action": [
"codeartifact:DescribePackageVersion",
"codeartifact:DescribeRepository",
"codeartifact:Get*",
"codeartifact:List*",
"codeartifact:ReadFromRepository"
],
"Resource": "*"
}
]
}

For cross-account write access, the repository will require the following resource policy,
{
"Version": "2012-10-17",
"Statement": [
{
"Principal": {
"AWS": "arn:aws:iam::345125489763:root"
},
"Effect": "Allow",
"Action": [
"codeartifact:GetRepositoryEndpoint",
"codeartifact:PublishPackageVersion",
"codeartifact:PutPackageMetadata"
],
"Resource": "*"
}
]
}

Usage
Other than configuration, usage is the same as adding any other repository to poetry.
The plugin is configured in the pyproject.toml file, below is an example of adding three AWS CodeArtifact repositories..
[[tool.poetry-plugin-code-artifact.sources]]
name="dev" # The name of the repositroy in poetry
aws-codeartefact-domain="my-domain" # The AWS CodeArtifact domain.
aws-codeartefact-owner="564131876131" # The AWS CodeArtifact domain owner.
aws-codeartefact-region="us-east-1" # The AWS CodeArtifact region.
aws-codeartefact-repository="dev" # The AWS CodeArtifact repository name.

[[tool.poetry-plugin-code-artifact.sources]]
name="qa"
aws-codeartefact-domain="my-domain"
aws-codeartefact-owner="564131876131"
aws-codeartefact-region="us-east-1"
aws-codeartefact-repository="dev"

[[tool.poetry-plugin-code-artifact.sources]]
name="prod"
aws-codeartefact-domain="my-domain"
aws-codeartefact-owner="564131876131"
aws-codeartefact-region="eus-east-1"
aws-codeartefact-repository="dev"

To use the above repositories via poetry, just use the normal commands,
Note: You must first be logged into AWS with an identity that has the correct permissions as given in the prerequisites section above. For more information on configuring credentials, see https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html
# To add a dependency,
poetry add my-lib # Searches all repositories
# or
poetry add my-lib --source dev # Prioritizes dev repository then searches all repositories.

# To publish a dependency,
poetry publish -r dev
