## CPUs

At the moment it is not possible to dynamically parametrize the number of CPUs for a service via Maven properties or environment variables.

To change the default value (`cpus: 1`) it is necessary to edit the Docker Compose file.


### Example: Keycloak service using 2 CPU cores

`docker-compose.yml` and `docker-compose-cluster.yml`:
```
services:
    ...
    keycloak:
        ...
        cpus: 2
        ...
```

`docker-compose-crossdc.yml`:
```
services:
    ...
    keycloak_dc1:
        ...
        cpus: 2
        ...
    keycloak_dc2:
        ...
        cpus: 2
        ...
```
