Starting a new phoenix application

gistfile1.txt

# Phoenix, by default, uses a Postgres database, so start one via docker
docker pull postgres
# Expose it on port 8432
docker run -p 8432:5432 --name hello-postgres -e POSTGRES_PASSWORD=postgres -d postgres

# Install Erlang, Elixir, and now Phoenix
mix archive.install https://github.com/phoenixframework/archives/raw/master/phx_new.ez
# Create a new Phoenix app
mix phx.new hello
# Edit config/dev.exs and update your hostname. Add a port (default is 5432, but I've mapped it to 8432)
# Create your database
mix ecto.create
# Run Phoenix
mix phx.server
