Resolve "Add trivy job to scan only dependencies"

# 🧱 Trivy dependency analysis

## Description

Run a security issue detection in your local dependencies using

[Trivy](https://github.com/aquasecurity/trivy), a Simple and Comprehensive

Vulnerability Scanner for Containers and other Artifacts. More details on Trivy

vulnerability detection capabilities are available in its official

[README](https://github.com/aquasecurity/trivy#vulnerability-detection)

!!! warning

    With the default configuration, this job will fail if errors are detected.

    It's the recommended configuration to reduce security risks in your

    software. You can disable this behavior by setting the value `0` to the

    variable `TRIVY_EXIT_CODE`.

## How to use it

1. Ensure that your dependency manager is supported in [dependencies check

   section](#dependencies-check)

2. Choose a version in [version list](#versions)

3. Add the corresponding URL to your `.gitlab-ci.yml` file (see [Getting

   started](/getting-started)). Example:

    ```yaml

    include:

      - remote: 'https://jobs.go2scale.io/trivy_dependency.yml'

    ```

4. If you need to customize the job (stage, variables, ...) 👉 check the [jobs

   customization](/getting-started/#jobs-customization)

5. Well done, your job is ready to work ! 😀

## Job details

* Job name: `trivy_dependency`

* Docker image: [`aquasec/trivy`](https://hub.docker.com/r/aquasec/trivy/)

* Default stage: `static_tests`

### Dependencies check

Trivy runs dependencies analysis using the **lock files** of dependency

managers.

!!! info

    A lock file in development is an auto built file by your dependency

    manager which describes **exactly** all dependencies used with their

    precise version. It's complementary with your classical requirement file

    and permits to ensure that every environment get the exact same

    dependencies versions. Goal is to ensure that your application will always

    behave the same way, without any changes that may break a feature.

    It is

    [recommended](https://myers.io/2019/01/13/what-is-the-purpose-of-a-lock-file-for-package-managers/) to

    have these files in your version control system, to ensure everyone will

    get the same behavior from your dependencies.

    More details about lock files in [this

    post](https://myers.io/2019/01/13/what-is-the-purpose-of-a-lock-file-for-package-managers/)

List of supported lock files :

| Language | Lock file |

|:-|:-

| Ruby | `Gemfile.lock` |

| Python | `Pipfile.lock`, `poetry.lock` |

| PHP | `composer.lock` |

| NodeJS | `package-lock.json`, `yarn.lock` |

| Rust | `Cargo.lock` |

To get more information, see [trivy

documentation](https://github.com/aquasecurity/trivy#application-dependencies).
