Setting Webhook (Frontend URL):
The default URL is set to the machine’s IP address. To ensure proper operation, ensure that this address is accessible or specify anFLO_FRONTEND_URL environment variable.
One possible solution for this is using a service like ngrok (https://ngrok.com/), which can be used to expose the frontend port (4200) to the internet.
Redis Configuration
Set theFLO_REDIS_URL environment variable to the connection URL of your Redis server.
Please note that if a Redis connection URL is specified, all other Redis properties will be ignored.
If you don’t have the Redis URL, you can use the following command to get it. You can use the following variables:
REDIS_USER: The username to use when connecting to Redis.REDIS_PASSWORD: The password to use when connecting to Redis.REDIS_HOST: The hostname or IP address of the Redis server.REDIS_PORT: The port number for the Redis server.REDIS_DB: The Redis database index to use.REDIS_USE_SSL: Connect to Redis with SSL.
If you are using Redis Sentinel, you can set the following environment variables:
FLO_REDIS_TYPE: Set this toSENTINEL.FLO_REDIS_SENTINEL_HOSTS: A comma-separated list ofhost:portpairs for Redis Sentinels. When set, all other Redis properties will be ignored.FLO_REDIS_SENTINEL_NAME: The name of the master node monitored by the sentinels.FLO_REDIS_SENTINEL_ROLE: The role to connect to, eithermasterorslave.FLO_REDIS_PASSWORD: The password to use when connecting to Redis.FLO_REDIS_USE_SSL: Connect to Redis with SSL.FLO_REDIS_SSL_CA_FILE: The path to the CA file for the Redis server.
SMTP Configuration
SMTP can be configured both from the platform admin screen and through environment variables. The enviroment variables are only used if the platform admin screen has no email configuration entered. FLO will only use the configuration from the environment variables ifFLO_SMTP_HOST, FLO_SMTP_PORT, FLO_SMTP_USERNAME and FLO_SMTP_PASSWORD all have a value set. TLS is supported.
