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
        ...
