10.4. Worker process counts
You can control the number of worker processes that handle incoming requests in Red Hat Quay using environment variables. These values define how many parallel processes are started to handle tasks for different components of the system, such as the registry, the web UI, and security scanning.
If not explicitly set, Red Hat Quay calculates the number of worker processes automatically based on the number of available CPU cores. While this dynamic scaling can optimize performance on larger machines, it might also lead to unnecessary resource usage in smaller environments.
In Red Hat Quay on OpenShift Container Platform deployments, the Operator sets the following default values:
-
WORKER_COUNT_REGISTRY: 8 -
WORKER_COUNT_WEB: 4 -
WORKER_COUNT_SECSCAN: 2
| Variable | Type | Description |
|---|---|---|
| WORKER_COUNT | Number | Generic override for number of processes |
| WORKER_COUNT_REGISTRY | Number |
Specifies the number of processes to handle Registry requests within the |
| WORKER_COUNT_WEB | Number |
Specifies the number of processes to handle UI/Web requests within the container |
| WORKER_COUNT_SECSCAN | Number |
Specifies the number of processes to handle Security Scanning (e.g. Clair) integration within the container |
