If you decide to self host Faction instead of using the Managed Solution then you will need to ensure you include the proper Environment variables so that Faction integrates into your environement. 

Below are all of the Faction Enironment Variables needed to configure your Mongo DB, Secret Keys, and other settings. 

## Mongo Database configs 

FACTION_MONGO_HOST=127.0.0.1. #requireed

FACTION_MONGO_USER=faction_mongo_user #optional 
FACTION_MONGO_PASSWORD=faction_mongo_pass #optional 
FACTION_MONGO_AUTH_DATABASE=admin #optional

FACTION_REPORT_STORAGE=aws #optional 
FACTION_BUCKET_NAME=your-bucket #optional 
FACTION_TIER=teams #required 
FACTION_USERS=100 #optional

FACTION_SMTP_USER=sysadmin #optional 
FACTION_SMTP_PORT=587 #optional

  This is the key used for all symmetric key encryption.

  This variable has two options: local or aws. If you include aws then you also need to set AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY and create the an s3 bucket location in AWS. You can also use IAM permissions instead of including the AWS Keys.

These settings (FACTION_SMTP_SERVER, FACTION_SMTP_USER< FACTION_SMTP_PORT) are just used for the initial setup of Faction. They will be overridden when you save or test emails in the admin settings pages. This is useful for doing deployments in Kubernetes or ECS.
