mogipu v0.0.2

Mogipu

Monorepo Gitlab Image Publisher.

• It checks if the image is already published. (by checking the Gitlab registry)
• If not, it will execute a Gitlab CI job to build and publish the image.

Installation

npm install -g mogipu

Usage

mogipu

Configuration

For each project in your monorepo, a configuration file can be used. The configuration file can take multiple forms:

• a mogipu property in package.json
• a .mogipurc file in JSON or YAML format
• a .mogipurc.json, .mogipurc.yaml, .mogipurc.yml, .mogipurc.js, .mogipurc.ts, .mogipurc.mjs, or .mogipurc.cjs file
• a mogipurc, mogipurc.json, mogipurc.yaml, mogipurc.yml, mogipurc.js, mogipurc.ts, mogipurc.mjs, or mogipurc.cjs file inside a .config subdirectory
• a mogipu.config.js, mogipu.config.ts, mogipu.config.mjs, or mogipu.config.cjs file

Required Environment Variables

GITLAB_TOKEN=your-gitlab-token

The gitlab token is a Gitlab Access token that has permissions to read the registry.

Configuration Options

{
  // Required, the path to the dynamic Gitlab CI file part.
  "gitlabCiFile": "path/to/file",
  // Optional, defaults to "gitlab-ci.yml"
  "imageName": "image-name"
}

Project-specific Gitlab CI file

The Gitlab CI file is a normal Gitlab CI file, but with some special variable values that will be replaced by Mogipu. This is the file that is configured in the gitlabCiFile property. All the project-specific gitlab files will be merged into one .gitlab-ci-dynamic.yml file.

release-x:
  # You must use `needs` instead of `stage`.
  needs: []
  # An image used to build the project. For example Kaniko.
  image:
    name: gcr.io/kaniko-project/executor:v1.14.0-debug
    entrypoint: [""]
  # The script to build the project.
  script:
    - /kaniko/executor
      --context "${CI_PROJECT_DIR}${PACKAGE_DIR}"
      --dockerfile "${CI_PROJECT_DIR}${PACKAGE_DIR}/Dockerfile"
      --destination "${CI_REGISTRY_IMAGE}/${PACKAGE_NAME}:${PACKAGE_VERSION}"
  variables:
    # The variables to be replaced in the script.
    PACKAGE_VERSION: __PACKAGE_VERSION__
    PACKAGE_NAME: __PACKAGE_NAME__
    PACKAGE_DIR: __PACKAGE_DIR__

Empty Gitlab CI file

Due to limitations in Gitlab CI, conditional downstream jobs are not possible. To work around this, you can use an empty Gitlab CI file.

This file needs to exist in the root of your repository, with the name .gitlab-ci-empty.yml.

empty:
  image: alpine:latest
  needs: []
  variables:
    # Speed up the pipeline by skipping git clone.
    GIT_STRATEGY: none
  script:
    - echo 'nothing to do here'

Root Gitlab CI file

The root Gitlab CI file is the main Gitlab CI file that will be used to trigger the downstream jobs.

release:
  image: oven/bun:latest
  needs: []
  script:
    - bunx mogipu
  artifacts:
    paths:
      - .gitlab-ci-dynamic.yml

deploy:
  needs:
    - "release"
  trigger:
    include:
      - artifact: .gitlab-ci-dynamic.yml
        job: release
    strategy: depend
