A list of Docker files to dockerize Phoenix applications.
To start working on your Phoenix project with Docker, first be sure to
have Docker installed, following the instructions provided here.
Then, copy into your project's folder the Docker files (Dockerfile and docker-compose.yml)
according to the Phoenix's version you want to use, and change the YOUR_APP_FOLDER_NAME
value on the Dockerfile and docker-compose.yml file to the name of your project's folder.
This basic templates have two main volumes: one for the application itself, and one
for the database (postgres). So you will have to change your database config in
order to use this new volume to something like this:
# Configure your database for dev environment
config :you_app_name, YourAppName.Repo,
adapter: Ecto.Adapters.Postgres,
username: "postgres",
password: "",
database: "your_app_name_dev",
hostname: "db",
pool_size: 10
Once you have done this, you're ready to use your Phoenix application by executing
these commands on your terminal:
- Setup the web container with
docker-compose build web - Install dependencies with
docker-compose run web mix deps.get - Create your database with
docker-compose run web mix ecto.create - Migrate your database with
docker-compose run web mix ecto.migrate - Install Node.js dependencies with
docker-compose run web bash -c "cd assets; npm install" - Start the application with
docker-compose up
This step assumes you already followed instructions from previous paragraph.
- Create your testing database with
docker-compose run web env MIX_ENV=test mix ecto.create - Migrate your testing database with
docker-compose run web env MIX_ENV=test mix ecto.migrate - Run the test suite with
docker-compose run web mix test
