github-webhook-server

A Flask-based webhook server for managing GitHub repositories. It handles tasks such as repository setup, branch protection, and webhook configuration.

Pre-build container images available in:

quay.io/myakove/github-webhook-server

Build container

Webhook server to manage GitHub repositories. On start, it will configure the following for each repository:

Set branch protection based on config.yaml

Private repositories are not supported.

Build container

Using podman:

podman build --format docker -t github-webhook-server .

Using docker:

docker build -t github-webhook-server .

Setup

example.config.yaml
docker-compose-example.yaml

Getting started

Setup

Before running the application, ensure to set the following environment variables and configuration file:

WEBHOOK_SERVER_LOG_FILE: Path to the log file where the server logs are to be stored.
WEBHOOK_SERVER_DATA_DIR: Path to the data directory where the config.yaml file is located.
config.yaml: Configuration file that contains settings for the server and repositories, which should be placed in the WEBHOOK_SERVER_DATA_DIR directory.

Follow the instructions to build the container using either podman or docker as described in the Build container section. Once that is done, proceed with the configurations outlined below.

Config file

Minimum config to get started

github-app-id: 123456
webhook_ip: https://IP or FQDN
github-toekns:
  - <GITHIB TOKEN1>

repositories:
  my-repository-name:
    name: my-org/my-repository-name
    protected-branches:
      main: []

github-app-id: The ID of the GitHub app. Need to add the APP to the repository.
name: repository full name (org or user/repository name)
webhook_ip: Ip or FQDN where this app will run, this will be added as webhook in the repository setting
github-toekns: List of admin users token for the repositories
If slack_webhook_url configured for the repository a slack massages will be sent to the configured channel about new releases to pypi, new containers that was pushed

slack_webhook_url: https://hooks.slack.com/services/<channel>

if pypi configured for the repository a new version will be pushed to pypi on new GitHub release

token: pypi token with push permissions
tool: The tool to use to build the package, can be twine or poetry

pypi:
  token: pypi-token
  tool: twine

if tox configured for the repository a tox job will run on each push and new commits

tox: The tox tests to run, can be set of tests separated by , or all to run all tests defined in tox.ini

tox: all
tox_python_version: python3.11 # if passed run on specified python version else run on default

Top level array which define the defaults required check runs for all the repositories

default-status-checks:
  - "WIP"
  - "dpulls"
  - "SonarCloud Code Analysis"
  - "can-be-merged"

protected-branches:
  main: []

This tool configure branch protection and set required to be run for each branch to pass before the PR can be merged

if the repository have the file .pre-commit-config.yaml then pre-commit.ci - pr will be added, can be excluded by set it in exclude-runs

protected-branches: array of branches to set protection
branch name: List of required to be run to set for the branch, when empty set default-status-checks as required
include-runs: Only include those runs as required
exclude-runs: Exclude those runs from the default-status-checks

By default, we create a verified_job run, for each PR the owner needs to comment /verified to mark the PR as verified In order to not add this job set verified_job to false

verified_job: false

if container is configured for the repository we create build-container run that will build the container on each PR push/commit Once the PR is merged, the container will be build and push to the repository if release is set to true a new container will be pushed with the release version as the tag if the merged PR is in any other branch than main or master the tag will be set to branch name, otherwise tag will be used

username: User with push permissions to the repository
password: The password for the username
repository: the repository to push the container, for example quay.io/myakove/github-webhook-server
tag: The container tag to use when pushing the container
release: if true a new container will be pushed with the release version as the tag

container:
  username: username
  password: password
  repository: repository path
  tag: latest
  release: true

If docker is configured for the repository we log in to docker.io to increase pull rate limit

docker:
  username: username
  password: password

if Jira is configured for the repository we create a new issue (story) for the PR and assign it to the owner. On new commit create closed sub-task under the PR story with the commiter as assignee On reviewed PR create closed sub-task under the PR story with the reviewer as assignee

server: FQDN Jira server url
project: project key to open the issue
token: Jira token
epic: epic name, if provided a new issue will be created under the epic
user-mapping: mapping from github username to jira username if different

jira setting can be placed as global (for all repositories) or per repository. jira in repository setting will override jira in global setting for the repository

jira:
  server: jira server url
  project: project key to open the issue
  token: jira token
  epic: epic name # Optional
  user-mapping:
    github username: jira username

To enable jira for a repository, set jira-tracking: true in repository settings

repositories:
  my-repository:
    jira-tracking: true

Supported actions

Following actions are done automatically:

Add reviewers from OWNERS file, support add different reviewers based on files/folders.
Set PR size label.
New issue is created for the PR.
Issues get closed when PR is merged/closed.

OWNERS file example

  - myakove
  - rnetser
reviewers:
  any: # will be added to all PRs
    - myakove

Main Functionalities

Logging Setup

The webhook server configures custom logging with color-coded log level names to enhance readability. It also supports optional logging to a file when 'WEBHOOK_SERVER_LOG_FILE' is set in the environment. This feature uses a rotating file handler to manage log rotation and is defined in the constants.py file.

Webhook Creation

Webhooks are automatically created for GitHub repositories based on settings defined in webhook.py. These webhooks enable real-time integration with GitHub events such as push, pull requests, and more.

Usage Guide

To use the webhook server, first prepare the config.yaml file with the necessary repository and server configurations. Set the required environment variables, including WEBHOOK_SERVER_LOG_FILE and WEBHOOK_SERVER_DATA_DIR. Build and start the server using the instructions in the 'Build container' section.

Development

To run locally you need to export some os environment variables

poetry install

WEBHOOK_SERVER_DATA_DIR=/tmp/webhook_server_data

mkdir -p $WEBHOOK_SERVER_DATA_DIR
cp -f webhook-server.private-key.pem $WEBHOOK_SERVER_DATA_DIR/webhook-server.private-key.pem
cp -f config.yaml $WEBHOOK_SERVER_DATA_DIR/config.yaml
export WEBHOOK_SERVER_PORT=5003

export FLASK_DEBUG=1
export WEBHOOK_SERVER_DATA_DIR=$WEBHOOK_SERVER_DATA_DIR
poetry run python webhook_server_container/app.py
