## 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
|
||
|
|
...
|
||
|
|
```
