Follow the 3 simple steps below to contribute in the hub. You'll see, it will all go smoothly! 👇

### 🍴 Step 1: Fork!

The first step is to create your own copy of the

[`r2devops/hub`](https://gitlab.com/r2devops/hub/) repository to be

[`r2devops/hub`](https://gitlab.com/r2devops/hub/) repository, to be

able to work on it before merging your update in the real project.

1. Go on the fork page creation: [`r2devops/hub`](https://gitlab.com/r2devops/hub/-/forks/new)

1. Select the group in which you want to create the fork

1. Create a new directory dedicated to your job in `jobs/` folder if you want to add a new job. You can use the [job

   template](https://gitlab.com/r2devops/hub/-/tree/latest/tools/job_template/job_name)

   as starting point

1. Ensure to respect rules in this guide

1. Do not update the CI/CD configuration (file `.gitlab-ci.yml`)

   as starting point.

2. Be sure to respect the rules we describe in this guide.

3. Do not update the CI/CD configuration (file `.gitlab-ci.yml`).

4. Test your job and ensure it works!

### 🚀 Step 3: Merge request

??? note "2. Create a new merge request in your fork (`Merge Requests > New merge request`) 👇"

    1. Select branches

        * As `Source branch`, select the branch in which you have worked in

        your fork (usually `latest`)

        * As `Target branch`, select latest in `r2devops/hub` project

        * Click on `Compare branches and continue`

    1. In `Title`: add short description of your contribution

        your fork (usually `latest`).

        * As `Target branch`, select latest in `r2devops/hub` project.

        * Click on `Compare branches and continue`.

    1. In `Title`: add short description of your contribution.

    1. In `Description`:

        * Do not remove the default content, this is the Definition of Done

            (DoD)

        * Do not remove the default content, this is the [Definition of Done (DoD)](https://go2scale.io/definition-of-done-a-recipe-for-optimal-results/)!

        * Add a description of your contribution with all information

          permitting us to understand what you have done and why. If your

          contribution is related to an existing issue, add a reference:

            ## Definition of Done

            [...]

            ```

        * Add link to your job running and working in a publicly accessible

          Gitlab project

#### 🧮 Variables

In order to be customizable, your job should use `variables`. This section

permits defining environment variables, usable by the job script.

allows to define environment variables, usable by the job script.

!!! tip

    Set default values to your variables to reflect the most common use-case,

    in this way, your job will remain plug-and-play while being customizable

    Set default values to your variables to reflect the most common use-case. 

    This, your job will remain plug-and-play while being customizable.

Example of relevant situation to use variable:

* File name

* Path to files or folders

* Any options/parameters used by the job

* Enable or disable job features

* Version of tools retrieved during the job

* File name.

* Path to files or folders.

    your job, it can be tricky to find the perfect image.

The better place to found a docker image is the [docker

The better place to find a docker image is the [docker

there with the following steps:

??? note "1. Search for an image prepared with the tool you want to run"

    1. Search for an image prepared with the tool you want to run

        * This is the preferred situation with a ready-to-use docker image that

          doesn't require any additional installation.

        * *Example for `mkdocs` job:

          [`squidfunk/mkdocs-material`](https://hub.docker.com/r/squidfunk/mkdocs-material)*

        * If you found it, check it with general guidelines below

          [`squidfunk/mkdocs-material`](https://hub.docker.com/r/squidfunk/mkdocs-material)*.

    * The image must be versioned and not only with `latest` tag. ==If image

      isn't versioned: it's not usable for your job==

    * It should be actively maintained, with frequent updates and contains

      recent versions

    * The image should be small, containing only required tools

    * The image should be efficient to run the job

    * A large usage of the image can be a good indicator but take care, it

    * The image should be efficient to run the job.

    * A large usage of the image can be a good indicator but be aware, it

      doesn't guarantee the quality neither the security of the image.

#### 📦 Artifacts

The vast majority of jobs produce a result. This result can be of different

kinds:

* Test report

* Build result

* Test report.

* Build result.

In both case, the result should be exposed by the job using the

[`artifact`](https://docs.gitlab.com/ee/ci/yaml/#artifacts){:target=blank}

    * In the case of a test report, you need to use `when: always` option under

      `artifacts` if you want to expose result even if job fails.

    * You can combine both a build result and a test report by using both

      `artifacts:paths` and `artifacts:reports`

      `artifacts:paths` and `artifacts:reports`.

Artifact can be configured at different level of integration in Gitlab

An artifact can be configured at different level of integration in Gitlab

    This is a way to integrate a report result in an user-friendly way in Gitlab's

### 📖 Job documentation

As described in [R2Devops/hub job

structure](/job-structure/#job-documentation), documentation of a job is

structure](/job-structure/#job-documentation), the documentation of a job is

written inside its `README.md` file.

!!! tip

    Don't hesitate to copy the documentation from another job as starting

    point. Example: raw content of [openapi

    point. For example, the raw content of [openapi

    `README.md`](https://gitlab.com/r2devops/hub/-/raw/latest/jobs/openapi/README.md)

We recommend including the following sections in your documentation:

* Objective: describe the goal of your job

* How to use it: a list of steps to quickly use your job

* Job details: describes details of job (name, docker image, stage, etc)

* Objective: describe the goal of your job.

* How to use it: a list of steps to quickly use your job.

* Job details: describes details of the job (name, docker image, stage, etc).

* Variables: table listing variables used by the job (name, description,

  default value, mandatory if needed)

* Artifacts: describes artifact defined by the job

  default value, mandatory if needed).

* Artifacts: describes artifact(s) defined by the job.

### 🚄 Compliance with another job

    in a standard path: `${CI_PROJECT_DIR}/website_build`.

So, if your job produce a static website output, ensure to store the result of

the build in `${CI_PROJECT_DIR}/website_build` and to configure this path as

artifact. See example in [`mkdocs`](/jobs/build/mkdocs/) job.

the build in `${CI_PROJECT_DIR}/website_build`, and to configure this path as

artifact. You can see an example in [`mkdocs`](/jobs/build/mkdocs/) job.

### 🧪 Test your job

follow these steps:

1. Test the behavior of your job inside a local container on your machine (with

   the same image as you want to use for the job). To simulate the Gitlab job

   that will run it on your project you can mount the repository folder inside

   the same image you want to use for the job). To simulate the GitLab job

   that will run it on your project, you can mount the repository folder inside

   the container:

      ```shell

      # Example if your job will use node:15.7-buster as Docker image docker run -v

2. Create your job configuration in a repository and test it locally using

   [`include

   local`](https://docs.gitlab.com/ee/ci/yaml/#includelocal){:target=blank}

   instead of `remote` from the hub. Example:
