Dockerize your Hanami applications

Dockerfile uses Ruby 2.5 Alpine as a base image and PostgreSQL 10.4 Alpine as a linked container.

Useful commands:

1. make dockerize – build image and run application on 2300 port
2. make shell – enter inside container
3. make shutdown – stop container

If you want to create database and run migrations you must simple use:

1. make shell
2. hanami db prepare
3. hanami db migrate

Step 1

Copy Dockerfile, docker-compose.yml and Makefile into your Hanami root directory.

Step 2

Replace DATABASE_URL in your .env.development with:

DATABASE_URL="postgresql://postgres:example@db/your_project_development

Replace DATABASE_URL in your .env.test with:

DATABASE_URL="postgresql://postgres:example@db/your_project_test

Step 3

Run make dockerize in your terminal.

Final step

Open http://localhost:2300 in your browser! 🍺
