go-sharpen-blade

Sharpening my Golang skills with coding challenges and skunkworks.

Some packages are only executed as unit tests, others can be run as commands using the -c <command> argument. The -l argument will list the available commands.

Work in Progress

  • This repository is currently transitioning from a single main.go to multiple cmd packages

Vanilla Go

  • This repository aims to minimize third-party library dependencies, allowing the author the most opportunity to idiomatically leverage the Standard Library.
  • Reusable code is extracted to github.com/mikebd/go-util

Running in Docker

  • docker build -t go-sharpen-blade . - Build the Docker image
  • docker run go-sharpen-blade - Run without arguments
    OR
    docker run go-sharpen-blade /app/go-sharpen-blade <args> - Run with the given arguments

Running Locally

  • go run ./main <args> - Run the main.go file with the given arguments

Arguments

Argument Description
-c <command> Command to run
-d <directory> Working directory
-h | --help Print the help message
-l List commands
-lt Log with timestamps (UTC)
-o11y-prometheus Enable Prometheus metrics

Prometheus Metrics

When run with -o11y-prometheus -c <command>, prometheus metrics are exposed on :2112/metrics. The program will wait for 20 seconds before exiting, so that the metrics can be scraped.

prometheus.yml:

scrape_configs:
  - job_name: sharpen_blade
    scrape_interval: 10s
    static_configs:
      - targets:
        - localhost:2112
