## What it is
dockerize is a Go CLI utility that simplifies running applications in Docker containers. It generates configuration files from templates and environment variables at container startup, tails log files to stdout/stderr, and waits for dependent services to become available before launching the main process.

## Use cases
- generate config files from environment variables at container startup
- wait for a database to be reachable before starting the app
- tail application log files to docker logs stdout
- template a settings file with a database URL env var
- delay container process until an HTTP or TCP service is up
- make file-logging apps like nginx work with docker logs

## When to choose
- your app reads config from files that can't use environment variables directly
- you need to block container startup until dependencies are listening
- your application logs to files instead of stdout/stderr
- you want a small static binary as a Docker entrypoint wrapper

## When to avoid
- your app supports environment variable configuration natively
- you use Kubernetes with ConfigMaps and init containers or entrypoint scripts
- you need full process supervision rather than a startup wrapper
- you prefer modern alternatives like envsubst or entrypoint shell scripts
