Environment Variables in Hybris local.properties

Question

I'm wondering if, in a Hybris properties file, there is a way to reference environment variables.

For example, in local.properties: my.property = ${MY_ENVIRONMENT_VARIABLE}

My searching has concluded that this is possible in Spring, but doesn't appear to work in Hybris.

Any thoughts would be appreciated.

It's possible to access to environment variables within hybris. A partner of my company found out this deep down in hybris documentation:

Platform allows you to specify properties also as environment variables

# security: make the platform *abort startup* if no one overrides the settings below
db.url=<CHANGE_ME>
db.username=<CHANGE_ME>
db.password=<CHANGE_ME>
# security: end

The special property value has been introduced exactly for such use cases where administrators want to ensure that: a) files do not contain sensible settings, and b) the system doesn't start up if those settings haven't been overridden.

On the server, those settings are to be exposed as environment variables just before starting Platform:

 foo$ export y_db_url=jdbc:mysql://my.secret-db-host.com/AlfavaMetraxis?useConfigs=maxPerformance&characterEncoding=utf8
 foo$ export y_db_username=Amy
 foo$ export y_db_password=Rory
 foo$ ./hybrisserver.sh start
...

As you can see, settings need to be prefixed and escaped in order to work as environment variable.

Hope this is useful for you.

I found this related to your question on Hybris Experts. Hope it helps.

It is not possible to access shell environment variables inside local.properties file. As a workaround you can do echo "my.property = $MY_ENVIRONMENT_VARIABLE" >> local.properties before starting platform.
