### ENABLE_MAJOR_UPDATES

**Type**: boolean|"enabled"|"disabled"\

**Required**: no\

**Default**: no

By default maintenance and security updates are always installed automatically while 

a container is live.  When this option is `yes`, `true` or `on`, the site will *also* 

automatically install major updates when they are released.

Note that major updates can include breaking changes and there is no guarantee the site will 

continue to operate without issues after an upgrade if this is enabled.  It is recommended 

this option is left disabled, and major upgrades are installed through deploying newer 

images.

### HOME_URL

declare DB_HOST DB_NAME DB_USER DB_PASS

declare HOME_URL SITE_URL
