Configuration
DotEnv
is a configuration pattern that loads environment variables from a .env file. Amezmo generates a
.env file for you at instance creation time.
This file is automatically available to you from your webroot.
Depending on the options you've chosen at instance creation time, you will see a set of predefined variables.
When a new deployment happens, the most recent .env file is copied into your deployments
target release directory.
Amezmo automatically generates a .env file for you when you launch an instance.
You can edit this file at anytime from the Configuration page.
Upon updating your configuration from the dashboard, the updates are immediately copied into your current release directory. Amezmo does not validate your file before placing it inside the root of your current release directory tree.
Your workers are reloaded via SIGHUP after your configuration file is copied into your release directory.
