Script variables

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 crete a directory for storing some file with a user name. The app install script could do mkdir -p $HDA_1ST_ADMIN"
