GameServer Pod Service Accounts
By default, Agones sets up service accounts and sets them appropriately for the
Pods that are created for
Since Agones provides
Pods with a sidecar container that needs access to Agones Custom Resource Definitions,
Pods are configured with a service account with extra RBAC permissions to ensure that it can read and modify the resources it needs.
Since service accounts apply to all containers in a
Pod, Agones will automatically overwrite the mounted key for the
service account in the container that is running the dedicate game server in the backing
Pod. This is done
since game server containers are exposed publicly, and generally dom’t require the extra permissions to access aspects
of the Kubernetes API.
Bringing your own Service Account
If needed, you can provide your own service account on the
Pod specification in the
apiVersion: "stable.agones.dev/v1alpha1" kind: GameServer metadata: generateName: "simple-udp-" spec: ports: - name: default containerPort: 7654 template: spec: serviceAccountName: my-special-service-account # a custom service account containers: - name: simple-udp image: gcr.io/agones-images/udp-server:0.7
If a service account is configured, the mounted key is not overwritten, as it assumed that you want to have full control of the service account and underlying RBAC permissions.
