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"
