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.

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

• This repository may minimize third-party library dependencies, but not obsessively so as a goal in itself.
• Opportunities may be taken for learning or other purposes to implement functionality here that is available in third-party libraries. These may be replaced with third-party libraries in the future as needs and interest change or time allows.
• Reusable code is extracted to github.com/mikebd/go-util

• 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

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

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
