GitHub repo watcher

An app that watches when a repository is created for a user and notifies on console. The app retains it state even after restarts using Bolt DB.

It exposes the number if user repositories in a prometheus metrics endpoint (/metrics) on port 8080.

Build

go build
chmod +x github-repo-watcher

Usage

Before running it keep in mind that the following parameters can be changed:

# Name or org that should be monitored
GITHUB_USERNAME=<username>
# Seconds between each collection (the GitHub API can get rate limitted quite fast)
CHECK_INTERVAL=300
# Directory of db data
DB_PATH=/tmp/db

Run

Local

export GITHUB_USERNAME=<user>
export CHECK_INTERVAL=300
export DB_PATH=/tmp/db

./github-repo-watcher

Dockerfile

Deploying with docker

docker build -t github-repo-watcher .
docker run -e GITHUB_USERNAME=<user> -e CHECK_INTERVAL=300 -e DB_PATH=/tmp/db -p 8080:8080 -v $(pwd)/db/:/tmp/db github-repo-watcher 

Helm

Deploying the chart

helm install my-deploy chart/ 

Deploying locally for testing (using kind)

kind create cluster --config kind.yaml
kind load docker-image github-repo-watcher 
helm install my-deploy chart/ -f chart/values.local.yaml
kubectl port-forward pod/<pod-name> 8080:8080 &
kubectl logs -f <pod-name>

To Do

• Helm chart
• Option for using authenticated calls in GitHub (to not be rate limitted immediatelly)
• Watch for deleted repos as well
• Use flags instead of env vars
