Lucky Framework Docker Development

README.md

1. Install Lucky in order to initialize projects: https://luckyframework.org/guides/installing/

2. Initialize a new project, then change to the project directory:

$lucky init my_project

$cd my_project

3. Add the Dockerfile, docker-compose.yml, and docker-compose.override.yml files the root directory of the project. Dockerfile exists to build the application based off of a Docker image that I built to run Lucky: https://hub.docker.com/r/revgum/lucky/)

4. Build the application $docker-compose build

5. Start the application in docker $docker-compose up
