Barcamp

Requirements:

• elixir
• nodejs
• yarn (install node first, then install yarn with npm i -g yarn, do NOT install it with brew or apt)
• postgresql

Now you can visit localhost:4000 from your browser.

Building Releases

Add a config/prod.secret.exs file and put your very secret configs in there:

use Mix.Config

config :barcamp, BarcampWeb.Endpoint,
  secret_key_base: "__SECRET_KEY__"

config :barcamp, Barcamp.Repo,
  username: "__DB_USER__",
  password: "__DB_PASSWORD__",
  database: "barcamp_prod",
  hostname: "localhost",
  pool_size: 10

You may use mix phx.gen.secret to generate a secret key.

Replace the CA in priv/cert/barcamp_key.pem and priv/cert/barcamp.pem with your public CA.

Build everything:

mix deps.get --only prod
MIX_ENV=prod mix compile
yarn --cwd assets install && yarn --cwd assets deploy
mix phx.digest
MIX_ENV=prod mix do ecto.create, release

See it in action:

mkdir deploy_here
cp _build/prod/rel/barcamp/releases/0.1.0/barcamp.tar.gz deploy_here/
cd deploy_here
tar xvf barcamp.tar.gz
PORT=4001 ./bin/barcamp start
./bin/barcamp migrate
./bin/barcamp create_user login password0!

Then navigate to localhost:4001.

Note: You do not need to have erlang or elixir where you are deploying a release.

Updates / Hot-Code-Swap

Bump the version:

def project do
   [
    ...
    version: "0.1.1", # Bump the version here
    ...
   ]
end

Then:

MIX_ENV=prod mix release --upgrade
cp _build/prod/rel/barcamp/releases/0.1.1/barcamp.tar.gz deploy_here/releases/0.1.1/
./deploy_here/bin/barcamp upgrade 0.1.1
