# Use CodeArtifact from a VPC
<a name="use-codeartifact-from-vpc"></a>

If you cannot or do not want to enable private DNS on your `com.amazonaws.region.codeartifact.repositories` VPC endpoint that you created in [Create VPC endpoints for CodeArtifact](create-vpc-endpoints.md), you must use a different configuration for the repositories endpoint to use CodeArtifact from a VPC. Follow the instructions in [Use the `codeartifact.repositories` endpoint without private DNS](#use-codeartifact-from-vpc-no-private-dns) to configure CodeArtifact if the `com.amazonaws.region.codeartifact.repositories` endpoint does not have private DNS enabled.

## Use the `codeartifact.repositories` endpoint without private DNS
<a name="use-codeartifact-from-vpc-no-private-dns"></a>

If you cannot or do not want to enable private DNS on your `com.amazonaws.region.codeartifact.repositories` VPC endpoint that you created in [Create VPC endpoints for CodeArtifact](create-vpc-endpoints.md), you must follow these instructions to configure your package manager with the correct CodeArtifact URL.

1.  Run the following command to find a VPC endpoint to use to override the hostname.

   ```
   $ aws ec2 describe-vpc-endpoints --filters Name=service-name,Values=com.amazonaws.region.codeartifact.repositories \
     --query 'VpcEndpoints[*].DnsEntries[*].DnsName'
   ```

    The output looks like the following.

   ```
   [
     [
       "vpce-0743fe535b883ffff-76ddffff.d.codeartifact.us-west-2.vpce.amazonaws.com"
     ]
   ]
   ```

1. Update the VPC endpoint path to include the package format, your CodeArtifact domain name, and CodeArtifact repository name. See the following example.

   ```
   https://vpce-0743fe535b883ffff-76ddffff.d.codeartifact.us-west-2.vpce.amazonaws.com/format/d/domain_name-domain_owner/repo_name
   ```

   Replace the following fields from the example endpoint.
   + *format*: Replace with a valid CodeArtifact package format, for example, `npm` or `pypi`.
   + *domain\$1name*: Replace with the CodeArtifact domain that contains the CodeArtifact repository that hosts your packages.
   + *domain\$1owner*: Replace with the ID of the owner of the CodeArtifact domain, for example, `111122223333`.
   + *repo\$1name*: Replace with the CodeArtifact repository that hosts your packages.

   The following URL is an example npm repository endpoint.

   ```
   https://vpce-0dc4daf7fca331ed6-et36qa1d.d.codeartifact.us-west-2.vpce.amazonaws.com/npm/d/domainName-111122223333/repoName
   ```

1. Configure your package manager to use the updated VPC endpoint from the previous step. You must configure the package manager without using the CodeArtifact `login` command. For configuration instructions for each package format, see the following documentation.

   + nuget: [Configure nuget or dotnet without the login command](nuget-cli.md#nuget-configure-without-login)
