Provision the empty containers with the content from the liferay configuration (e.g. settings and lar stuff)

[maxhbr]

according to [1] one has to have

• a sql dump of the postgres and
• the content of $CATALINA_HOME/data

to restore an liferay instance. We could use content, from a freshly provisioned instance, to create some files which can be used while building the images, to get an already provisioned liferay.

These two parts thus could be added as default content to sw360postgres and sw360empty respectively.
