This is a quick screencast to demonstrate how easy it is to deploy an Elixir application to Gigalixir, a hosting platform built specifically for Elixir.
I included a condensed text version of the video for those who prefer it, but you can find the full guide here.
Create the Phoenix App
# install the generator
$ mix archive.install hex phx_new 1.5.6
# generate the project
$ mix phx.new foobar
# cd into the directory
$ cd foobar
# create our database
$ mix ecto.create
# start the server
$ mix phx.server
# commit your code to git
$ git init && git commit -am 'Initial Commit'
Prod Configuration
You will have to adjust some prod configuration for our app to work on Gigalixir. Let's make the following adjustments to the config/prod.exs file.
config :foobar, FoobarWeb.Endpoint,
- url: [host: "example.com", port: 80],
+ url: [host: "your-app-name.gigalixirapp.com", port: 443],
- cache_static_manifest: "priv/static/cache_manifest.json"
+ cache_static_manifest: "priv/static/cache_manifest.json",
+ force_ssl: [rewrite_on: [:x_forwarded_proto]]
+ config :foobar, Foobar.Repo,
+ ssl: true
Deploy to Gigalixir
# install gigalixir (using Homebrew)
$ brew tap gigalixir/brew && brew install gigalixir
# sign up for gigalixir
$ gigalixir signup
# log in to gigalixir
$ gigalixir login
# create the app
$ gigalixir create
# set up your buildpacks
$ echo "elixir_version=1.10.3" > elixir_buildpack.config
$ echo "erlang_version=22.3" >> elixir_buildpack.config
$ echo "node_version=12.16.3" > phoenix_static_buildpack.config
# commit those changes
$ git commit -am 'Set up gigalixir buildpacks'
# create your prod database
$ gigalixir pg:create --free
# deploy your app
$ git push gigalixir main
# open your prod app
$ gigalixir open
