bf2-arch-bot Project

This project is a github bot used to support workflows on the Application Services Architecture repo.

Application Services Architecture has a number of different types of record:

• ADRs (Architecture Decision Records) -- Apply decisions (or APs) to a particular managed service.
• PADRs (Platform ADRs) -- Apply decisions across all services.
• APs (Architectural Patterns) -- candidates for PADRs.

This project uses Quarkus, the Supersonic Subatomic Java Framework.

Features

Creation of records

Record pages can be created automatically from GitHub issues via a comment. The bot will respond to the comment, opening a PR which creates a new record and automatically merging it. The record id etc. are automatically managed. See org.bf2.arch.bot.CreateDraftRecordFlow for more details.

From there the author writes their content and eventually opens a second

Labelling PRs

When record-altering PRs get opened the bot will label them. A simple state machine model is used, driven by events (delivered via webhook) on the PR & its corresponding issue.

   <start>
      |
      v
needs-reviewers
      |
      v
being-reviewed
      |
      v
awaiting-merge
      |
      v
    <end>

See org.bf2.arch.bot.ArchReviewStateMachineFlow.

Perodically the bot will check for issues where the discussion appears to have stalled and labels them for attention. See org.bf2.arch.bot.StalledDiscussionFlow.

Automatic reviewing of PRs

org.bf2.arch.bot.PrReviewFlow seeks to provide some basic automated review of PRs which touch records. The intent is to provide some consistency between records, while not being too annoying.

Running the application in dev mode

You can run your application in dev mode that enables live coding using:

./mvnw compile quarkus:dev

NOTE: Quarkus now ships with a Dev UI, which is available in dev mode only at http://localhost:8080/q/dev/.

Packaging and running the application

The application can be packaged using:

./mvnw package

It produces the quarkus-run.jar file in the target/quarkus-app/ directory. Be aware that it’s not an über-jar as the dependencies are copied into the target/quarkus-app/lib/ directory.

The application is now runnable using java -jar target/quarkus-app/quarkus-run.jar.

If you want to build an über-jar, execute the following command:

./mvnw package -Dquarkus.package.recordType=uber-jar

The application, packaged as an über-jar, is now runnable using java -jar target/*-runner.jar.

Creating a native executable

You can create a native executable using:

./mvnw package -Pnative

Or, if you don't have GraalVM installed, you can run the native executable build in a container using:

./mvnw package -Pnative -Dquarkus.native.container-build=true

You can then execute your native executable with: ./target/bf2-arch-bot-1.0.0-SNAPSHOT-runner

If you want to learn more about building native executables, please consult https://quarkus.io/guides/maven-tooling.
