After you create a managed cluster as described in Create a managed cluster, proceed with adding bare metal hosts using the Mirantis Container Cloud CLI using the instruction below.
To add a bare metal host using API:
Log in to the host where your management cluster kubeconfig
is located
and where kubectl is installed.
Create a secret YAML file that describes the credentials of the new bare metal host.
Example of the bare metal host secret:
apiVersion: v1
data:
password: <credentials-password>
username: <credentials-user-name>
kind: Secret
metadata:
labels:
kaas.mirantis.com/credentials: "true"
kaas.mirantis.com/provider: baremetal
kaas.mirantis.com/region: region-one
name: <credentials-name>
namespace: <managed-cluster-project-name>
type: Opaque
In the data
section, add the IPMI user name and password in the base64
encoding to access the BMC. To obtain the base64-encoded credentials, you
can use the following command in your Linux console:
echo -n <username|password> | base64
Apply this secret YAML file to your deployment:
kubectl apply -f ${<bmh-cred-file-name>}.yaml
Create a YAML file that contains a description of the new bare metal host.
Example of the bare metal host configuration file with the worker
role:
apiVersion: metal3.io/v1alpha1
kind: BareMetalHost
metadata:
labels:
kaas.mirantis.com/baremetalhost-id: <unique-bare-metal-host-hardware-node-id>
hostlabel.bm.kaas.mirantis.com/worker: "true"
kaas.mirantis.com/provider: baremetal
kaas.mirantis.com/region: region-one
name: <bare-metal-host-unique-name>
namespace: <managed-cluster-project-name>
spec:
bmc:
address: <ip_address_for-bmc-access>
credentialsName: <credentials-name>
bootMACAddress: <bare-metal-host-boot-mac-address>
online: true
For a detailed fields description, see BareMetalHost.
Apply this configuration YAML file to your deployment:
kubectl apply -f ${<bare-metal-host-config-file-name>}.yaml
Now, proceed with Deploy a machine to a specific bare metal host.
