# Bitbucket PR gating using Local Scanner

The Aikido Local Scanner can be used to enforce security gates in your CI pipeline.

{% hint style="info" %}
You can also use PR gating with your cloud-connected workspaces (GitHub, BitBucket, etc). Check out our CI [Integration section](https://help.aikido.dev/section/ci-integrations/sg3q6UrIf4qE).
{% endhint %}

PR gating ensures that new code meets your security standards before it is merged into the default branch. It scans only the changes introduced in the pull request. If the scan detects new issues that meet or exceed your configured severity threshold, the CI pipeline fails.

This prevents new vulnerabilities from being introduced while allowing existing findings to be addressed separately.

{% hint style="info" %}
We also support [release gating](/container-image-scanning/local-image-scanning/release-gating-for-container-images-using-local-image-scanner.md) for teams that want to enforce checks at release time.
{% endhint %}

To enable PR gating, add the `--fail-on <severity>` option to select your preferred severity level. Then, add the `--gating-mode pr` option to signify that you wish to perform PR gating. You must also specify the base (`--base-commit-id <commit-id>`) and head commit (`--head-commit-id <commit-id>`). If there a scan was previously performed on the base commit id, the scan results will be compared to those. If not, the results will be compared to the most recent scan on your default branch.

For general information about setting up the Local Scanner in a Bitbucket environment, check out [this article](/code-scanning/local-code-scanning/bitbucket-pipeline-setup-for-local-code-scanning.md).

Example `bitbucket-pipelines.yml` for PR gating:

```yaml
image: aikidosecurity/local-scanner:latest

pipelines:
  pull-requests:
    "**":   # this applies the pipeline to all pull requests
      - step:
          name: Aikido PR Gating Scan
          script:
            - >- 
              aikido-local-scanner scan ./
              --apikey $AIKIDO_API_KEY
              --repositoryname $BITBUCKET_REPO_SLUG
              --branchname $BITBUCKET_BRANCH
              --gating-mode pr
              --fail-on critical
              --base-commit-id $BITBUCKET_PR_DESTINATION_COMMIT
              --head-commit-id $BITBUCKET_COMMIT
```

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/code-scanning/local-code-scanning/pr-gating/bitbucket-pr-gating-using-local-scanner.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.
