## Init is run on host
## For now it is run every time the script is launched, but
## it should be launched only once after build.

## Accessible variables are:
## - SERVICE_NAME        Name of current service
## - DOCKER_BASE_IMAGE   Base image from which this service might be built if any
## - SERVICE_DATASTORE           Location on host of the DATASTORE of this service
## - SERVICE_CONFIGSTORE         Location on host of the CONFIGSTORE of this service
