When you generate a new Maze project, we include Docker
and docker-compose.yml
files to simplify development. This is an alternative way of getting an Maze project up and running quickly and doesn't require installing a database.
The Docker file will have everything you need to build and run your maze project. This includes all needed the libraries, Nodejs, Crystal and Maze command line tools. It starts from the official crystallang/crystal:{version}
docker image.
It will also add the project to the /app
folder on the image so you can use this in production as well.
The docker-compose.yml
file will allow you to easily get up and running. It includes the database
, mailcatcher
, migrate
, app
, and web
containers.
database
containerThis container is using an image based on the -d
option you chose when you created the project. Right now, we support pg, mysql, sqlite
A db
volume is also created so you can start and stop the containers but the data will still be available.
mailcatcher
containerMail Catcher is a simple smtp server that will allow you to see the email that gets generated. You can access the user interface by hitting . If you generate mailers, it will configure the SMTP_URL
to point to the mail catcher container.
migrate
containerThis container will run the migrations using maze db migrate seed
. It will wait for the database port to be available before running the migrations. This container will exit after completing the migrations.
app
containerweb
containerThis container will run npm install && npm run watch
. This will compile your front-end assets and will watch for changes. You can see the webpack configuration in the config/webpack
directory to see what assets are compiled.
You can launch the docker-compose environment by running:
Once all the docker containers are launched, you can access the site using:
And you can access the mailcatcher at:
This container will run maze watch
on port 3000. You can access the application at . The external project directory is mapped to /app/local
so as you make changes to your project and maze will watch for changes, recompile and re-launch the application.
