CI/CD templates

Info

What is a catalog?

To use Plumber, you have to register your CI/CD templates and components in your Plumber instance catalog. This is a registry of GitLab CI/CD templates sourced from a git repository.

🔎 Guides

💾 Create a catalog

Info

Sources of Plumber catalog are GitLab repositories
You can store several templates per repository
You must have at least Maintainer access

Create a GitLab repository
In this repository:
1. Create R2 file
2. Create CI/CD configuration
3. (optional) Create documentation file
4. (optional) Setup versioning
5. (optional) Create changelog file
Login on Plumber
In CI/CD Catalog > Import R2 templates page: import your repository

🔄 Update catalog resources

Update your template(s) in the GitLab repository
Create new version tag
Login on Plumber
In “Import templates” page: click on refresh button

❌ Delete catalog resources

Login on Plumber
In “Import templates” page: click on delete button

⚙️ Template R2 file

Each template on Plumber must have its own R2 file. It defines template metadata.

It can be located anywhere in a repository
It uses the YAML format
File extension have to be .r2.yml
The file name is the template name

Tip

Example of R2 file docker_build.r2.yml for the template docker_build

files:
  template: ./docker_build/docker_build.yml
  documentation: ./docker_build/README.md
  changelog: ./docker_build/CHANGELOG.md
data:
  description: 'Build and publish a Docker image'
  icon: 🐳
  labels:
    - Docker
    - Build
  license: MIT
  deprecated: false

Keyword	Description	Default
`files:template`	(Mandatory) Relative path(*) to the template CI/CD configuration
`files:documentation`	Relative path(*) to the documentation file
`files:changelog`	Relative path(*) to the changelog file
`data:description`	The template description
`data:icon`	Icon of the template (see emoji list)	`📋`
`data:labels`	List of template labels (see list of available labels below)	`[]`
`data:license`	The template license
`data:deprecated`	Set the template as deprecated	`false`

Info

Template visibility

The visibility of a template is the same than the visibility of its repository

Info

(*) Relative path

Path of files is relative from the location of the R2 file

🛠️ Template CI/CD conf

This file, usually named with the template name with .yml extension contains GitLab CI/CD configuration in yaml format. It can contains any piece of configuration, from one keyword to a full pipeline. More info:

GitLab CI/CD pipeline configuration reference

Info

Example of CI/CD conf

docker_build:
  stage: build
  image:
  name: gcr.io/kaniko-project/executor:${IMAGE_TAG}
  entrypoint: ['']
  variables:
  COMMIT_CREATE_LATEST: 'false'
  DOCKER_CONTEXT_PATH: ''
  DOCKERFILE_PATH: 'Dockerfile'
  IMAGE_TAG: 'v1.8.1-debug'
  script:
    - echo "Truncated example of script"

📚 Template documentation

This file, usually named README.md, contains the documentation of a template in markdown format. It should explains what the template does, how to use it and to customize it. A clear documentation is important: no one wants to use a template without it.

Info

Example of documentation

## Objective

Build a container image of your application from a Dockerfile at the root of
your project, and push it to a remote registry or multiple ones. This is done
using [kaniko](https://github.com/GoogleContainerTools/kaniko).

## How to use it

1. Create a
   [Dockerfile](https://docs.docker.com/get-started/part2/#sample-dockerfile)
   (by default at the root of your project) to containerize your application
2. Include template in your CI/CD conf (see quick use above)
3. Customize the template if it's relevant

## Variables

| Name                   | Description                                   | Default      |
| ---------------------- | --------------------------------------------- | ------------ |
| `COMMIT_CREATE_LATEST` | In a commit context, also update `latest` tag | `false`      |
| `DOCKER_CONTEXT_PATH`  | Path of build context from to repository root | ` `          |
| `DOCKERFILE_PATH`      | Path to Dockerfile from the build context     | `Dockerfile` |

📄 Template versioning

Template versioning rely on source repository git tags. 2 options are supported in Plumber:

Tags scoped to all templates of the repository, without prefix. Ex: 1.2.3
Tags scoped to only one template, prefixed with its path. Ex: docker_build@1.2.3

Info

The version latest is created using the HEAD of default branch
Versions should follows the semantic versioning (MAJOR.MINOR.PATCH)
The first version recommended for a template is 0.1.0
Several templates can be versioned in the same repository

In order to create automatically versioning tags for your templates, you have to create a changelog file for each templates and add the template template_release in your repository CI/CD configuration.

🏗 Template changelog

This file, usually named CHANGELOG.md, contain the changelog of a template following the keep a changelog structure and using markdown syntax.
