loggy

A tiny microservice for aggregating Gelf logs and posting them into a Slack channel.

NOTE: I'm currently working on the book Bootstrapping Microservices with Docker, Kubernetes and Terraform.

Follow on Twitter (@ashleydavis75) to be updated on progress!

To use

Create a Docker image from this repo.

Supply the following environment variables:

• SLACK_WEB_HOOK: Set this to the web hook for posting to your designated Slack workspace.
• SLACK_CHANNEL_NAME: This is the channel that messages should be posted to.

Docker-Compose example:

You can add loggy to your Docker-Compose files as follows (assuming myservice is a microservice you have added):

version: '3'
services:
    
loggy:
    image: loggy
    build: 
    context: ./loggy
    dockerfile: Dockerfile-dev
    container_name: loggy
    network_mode: host 
    volumes:
    - /tmp/loggy/npm-cache:/root/.npm:z
    - ./loggy/src:/usr/src/app/src:z
    ports:
    - "12201:12201/udp"
    environment:
    - SLACK_WEB_HOOK=<your-Slack-web-hook-here>
    - SLACK_CHANNEL_NAME=<name-of-your-Slack-channel-here>
    restart: always
