Here are some environment variables that are available to be used in app install scripts:

  • HDA_APP_DIR: Directory of the webapp
  • HDA_IP: the internal IP of the HDA
  • HDA_APP_NAME: App name
  • HDA_DOMAIN: internal domain of this HDA
  • HDA_APP_USERNAME: admin username (if available, otherwise undefined)
  • HDA_APP_PASSWORD: admin password (if available, otherwise undefined)
  • HDA_1ST_ADMIN: username of the 1st admin user


Available in Amahi 7.2 and later:

These are only defined if the app has a database:

  • HDA_DB_DBNAME name of the database for the app
  • HDA_DB_USERNAME username of the database for the app
  • HDA_DB_PASSWORD password of the database for the app
  • HDA_DB_HOSTNAME hostname of the machine where the database is hosted (typically localhost, but please use this variable anyway)

Examples

  • Suppose the app needs to initialize the DB for an app with an initial admin user and password. The script could use echo "insert .... '$HDA_APP_USERNAME' ..."
  • Same thing with the domain name for this HDA.
  • Suppose there is a need to create a directory for storing some file with a user name. The app install script could do mkdir -p $HDA_1ST_ADMIN"
