Myumbrella

Elixir umbrella applications can be smoothly hot-upgraded with DeployEx.

Running Locally

To start your Phoenix server:

• Run mix setup to install and setup dependencies
• Start Phoenix endpoint with mix phx.server or inside IEx with iex -S mix phx.server

Now you can visit localhost:4000 from your browser.

Genreating a hot-upgrade release

1. Build the initial release (e.g., 0.1.0):

# Release the version 0.1.0
MIX_ENV=prod mix assets.deploy
MIX_ENV=prod mix release

2. Update the version (e.g., from 0.1.0 to 0.1.1) in version.txt
3. Build the new release with forced compilation:

MIX_ENV=prod mix assets.deploy
MIX_ENV=prod mix compile --force
MIX_ENV=prod mix release

Observer Web Notes

If using Observer Web, install it in only one app (recommended: the LiveView web app).
