Dot CI/CD

Overview

The purpose of this project is to store no application code but the required functionality to throw into CI (Travis and Github Actions) the code found in core (and probably more projects to come later) so it can execute some CI/CD basic stuff: build code, build docker images, publish them and run unit, integration and postman tests.

It includes from bare bash scripts, initial setup files to Docker images. In other words everything else that is not, in this first initiaive, the core application code.

The code and resources stored in this repo are meant to be consumed by the current CI/CD providers: Travis and Github Actions.

Resources

The CI configured in the application project will import the code found in this repo to make it available to its CI workspace.

This is the current directory structure.

There are 2 types of identified resources that are consequently located in two main directories.

Docker Resources

That's everything under dot-cicd/docker folder. It has two subtypes of Docker Resources: setup and tests.

Setup

It contains files to be eventually mounted as volumes in Docker. For this specific case it has the initialization scripts for the supported database images.

Tests

Here we have divided by the three types of tests: unit, integration and postman (curl), some shared resources and a DotCMS base image with everything it needs to be an operational instance.

It consits of Dockerfiles, Docker Compose, even scripts to embed in the actual image, and maybe script to invoke the whole thing.

Pipeline

This located under the dot-cicd/pipeline directory.

These are actual scripts that are considered the entry points to the pipeline. When using Travis, the .travis.yml file will reference scripts in this folder, which will use Google Cloud YAML files to build images and run the containers using Docker Compose.

This kind reources can be found at dot-cicd/pipeline/travis and specifically for the core project at dot-cicd/pipeline/travis. Meaning that a project can be "onboarded" to this new pattern by adding the corresponding directory here.

At the same time and by convetion, projects using a different CI/CD technology, should be included in dot-cicd/pipeline (e.g. dot-cicd/pipeline/github-actions) and subsequently "onboard" the desired projects onto it.

For Developers

All this explaining is very nice, but let's cut the chase to what develpers care, that is: How do I configure my project to consume the pipeline?

  1. Easy just create bash script called: discover.sh with the following content:
#!/bin/bash

[[ -s .cicd/seed.source ]] && source .cicd/seed.source
sh -c "$(curl -fsSL https://raw.githubusercontent.com/dotCMS/dot-cicd/master/seed/install-dot-cicd.sh)"

Save it in a directory called .cicd at the root of your project.

  1. Reference discover.sh from your current CI/CD provider. In the case of Travis it will look something like this:
...
before_install:
  - chmod +x .cicd/discover.sh
...
install:
  - .cicd/discover.sh

In the case of Github Actions it will look like this for every job step:

...
      - name: Prepare dot-cicd
        run: |
          chmod +x .cicd/discover.sh && .cicd/discover.sh
...

And that is it.

Caveats

This is a first initiative to satisfy the need of adding postman tests for the core project to the current Travis CI. Therefore a lot of things were implemented with core and Travis in mind.

There will certainly be major changes to this structure and the way of doing things as we include more CI/CD technologies and/or projects. So the refactoring to turn this as generic as we can will probably be an ongoing process until it reachs some maturity.
