# Automatic Swarm Nginx Loadbalancer
# Automatic Swarm Nginx Load Balancer
## Environment variables
This container has its own environment variables, AS WELL AS scanning for some environment variables associated with your services.
These should not be confused.
### Load balancer Configuration
### Load Balancer Configuration
#### Main configuration
| Key | Default | Options | Behaviour |
|----------------------------------------|---------|---------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| DOCKER_HOST | false | | Define a http endpoint representing your docker socket. If this is null, it connects to /var/lib/docker.sock |
| GLOBAL_CERT | false | Contents of an ssl certificate | If you want to provide a single cert for all endpoints, perhaps with a catch-all that may be later overriden, you can provide the whole contents of a certificates file here. |
| GLOBAL_CERT_KEY | false | Contents of an ssl certificates private key | The private key related to GLOBAL CERT. These must be provided in tandem. |
| BOUNCER_FORCED_UPDATE_INTERVAL_SECONDS | false | positive numbers | To force the bouncer to update on a schedule even if no changes are detected, measured in seconds |
| Key | Default | Options | Behaviour |
