# Docker

## Supported versions <a href="#supported-versions" id="supported-versions"></a>

The level of support for a language is defined as follows:

* Fully supported: Analysis will complete. All the language features are understood and examined.
* Supported: Most language features are understood and examined but the version includes unsupported features. Analysis might break or provide incomplete results.

Dockerfile versions 1.0 to 1.6 are supported.

## Language-specific properties <a href="#language-specific-properties" id="language-specific-properties"></a>

To discover and update the Docker-specific properties, navigate in SonarQube Cloud to *Your Project* > **Administration** > **General Settings** > **Languages** > **Docker**. See [Configuration overview](/sonarqube-cloud/analyzing-source-code/analysis-parameters/configuration-overview.md) for more information about setting properties.

## Dockerfiles <a href="#dockerfiles" id="dockerfiles"></a>

**No NoSonar Support:**

Trailing comments are not permitted in Dockerfiles. For this reason, our Dockerfile parser does not support NOSONAR comments to suppress issues. Issues and hotspots must be reviewed in the UI.

**Missing Uniform Filename Convention:**

Dockerfiles can have all kinds of names and do not need a file extension. For this reason, it is difficult for the scanner and the analyzer to recognize all Dockerfiles. By default, all files named Dockerfile, Dockerfile.\*, or \*.dockerfile are considered Dockerfiles. If other conventions apply, these can be specified via the scanner property sonar.lang.patterns.docker.

## In-line suppression of issues <a href="#in-line-suppression-of-issues" id="in-line-suppression-of-issues"></a>

Adding the `NOSONAR` comment on the line will suppress all issues on that line:

* `NOSONAR` can be placed anywhere in the comment.
* The comment check is case-sensitive.

{% hint style="warning" %}
Rather than relying on this method, we suggest refining your analysis scope to avoid creating major gaps in your code review. Because the `NOSONAR` comment silences all current and future issues on a line without regard for their severity, it is an imprecise tool. Even if you only intend to hide a minor stylistic point, you could unintentionally obscure a serious security flaw.
{% endhint %}

# Agent Instructions
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://docs.sonarsource.com/sonarqube-cloud/analyzing-source-code/languages/docker.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.
