CI solution for Knot.x

[tomaszmichalak]

Is your feature request related to a problem? Please describe. Knot.x distribution (Knot.x Stack) consists of modules such as:

• Knot.x HTTP Server
• Knot.x Launcher
• Knot.x Fragments
• etc.

Knot.x Stack artifact is a ZIP file. This file is used to build Knot.x Docker image. This image is used via Knot.x Starter Kit to prepare custom, project specific Docker image - it contains its own configuration and system tests.

All changes to any repository should validate all elements: Stack, Docker, Starter Kit.

Describe the solution you'd like We want to explore Azure Pipelines to implement the CI solution for Knot.x. The initial design is a part of this task.

Design

1. We consider to use Knot.x Aggregator to clone all repositories and build Knot.x Stack using Gradle Composite Builds.

- script: |
    echo "Knot.x Stack"
    git clone https://github.com/Knotx/knotx-aggregator.git
    cd knotx-aggregator/development
    ./pull-all.sh -r modules -b $(Build.SourceBranchName)
    ./build-all.sh -r modules -d

Knot.x Stack artifact is stored in a local maven repository.

2. Build Knot.x Docker image

- script: |
    echo "Knot.x Docker"
    git clone https://github.com/Knotx/knotx-docker.git
    cd knotx-docker
    mvn clean package

3. Build & validate Knot.x Starter Kit

- script: |
    echo "Knot.x Starter Kit"
    git clone https://github.com/Knotx/knotx-starter-kit.git
    cd knotx-starter-kit
    gradle build

Elements to cover:

• how can we provide one pipeline definition for all repositories
