Limitations and Considerations
EasyHAProxy will not work with --network=host
:::danger Network Mode Incompatibility
The --network=host option cannot be used with the EasyHAProxy container itself due to its networking requirements.

Considerations for Multiple Replica Deployments in EasyHAProxy
:::warning Single Replica Deployment Recommended EasyHAProxy is designed for single replica deployment. :::
What happens with multiple replicas?
EasyHAProxy can still operate with multiple replicas; however:
-
Service Discovery: Each replica will independently discover services, which may lead to temporary inconsistencies among replicas (out-of-sync for a few seconds).
-
ACME/Certificate Issues: Running multiple replicas creates significant problems with Let's Encrypt and other ACME certificate issuance:
- Each replica will attempt to obtain its own certificate
- ACME challenges may be directed to different replicas, causing failures
- You may quickly hit certificate issuance rate limits
- Certificate renewal may fail unpredictably
:::danger Recommendation If you need to run multiple replicas for high availability, do not activate ACME/Let's Encrypt. Instead, use manually managed certificates or an external certificate management solution. :::
