# Link Containers to Code Repositories in Bulk via Tags (AWS ECR Only)

Linking containers to code repositories keeps related vulnerabilities in one place. This is useful when you manage many repositories and images.

Aikido can link containers automatically by reading a specific tag on the AWS ECR repository during scanning.

{% hint style="warning" %}
This only works for AWS ECR repositories.
{% endhint %}

### Required tag

You must add an AWS ECR repository tag with this exact key: `aik:repository`

Set the tag value to the full URL of the code repository you want to link.

Example:

<table><thead><tr><th width="177.1796875">Key</th><th>Value</th></tr></thead><tbody><tr><td><code>aik:repository</code></td><td><code>https://github.com/AikidoSec/demo-app-1</code></td></tr></tbody></table>

{% hint style="info" %}
This must be a tag on the **ECR repository**. It is not an image tag.
{% endhint %}

### How it works

On the next scan, Aikido reads the `aik:repository` tag. It then links the scanned container images to that repository automatically.

### Required AWS permission

If you use the Aikido scanner for containers, the scanner role also needs: `ecr:ListTagsForResource`

Without this permission, Aikido cannot read the repository tags.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.aikido.dev/container-image-scanning/configuration/link-containers-to-code-repositories-in-bulk-via-tags-aws-ecr-only.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
