Remove a regional cluster¶
Regional clusters are unsupported since Container Cloud 2.25.0. Mirantis does not perform functional integration testing of the feature and intends to remove the related code in Container Cloud 2.26.0. If you still require this feature, contact Mirantis support for further information.
This section describes how to remove a regional cluster.
To remove a regional cluster:
Log in to the Container Cloud web UI with the
Switch to the project with the managed clusters of the regional cluster to remove using the Switch Project action icon located on top of the main left-side navigation panel.
Verify that you have successfully deleted all managed clusters that run on top of the regional cluster to be removed. For details, see the corresponding Delete a managed cluster section depending on your cloud provider in Create and operate managed clusters.
Log in to a local machine where your management and regional clusters
kubeconfigfiles are located and where
The management or regional cluster
kubeconfigfiles are created during the last stage of the management or regional cluster bootstrap.
Verify that the bootstrap directory is updated.
Select from the following options:
For clusters deployed using Container Cloud 2.11.0 or later:
./container-cloud bootstrap download --management-kubeconfig <pathToMgmtKubeconfig> \ --target-dir <pathToBootstrapDirectory>
For clusters deployed using the Container Cloud release earlier than 2.11.0 or if you deleted the
kaas-bootstrapfolder, download and run the Container Cloud bootstrap script:
wget https://binary.mirantis.com/releases/get_container_cloud.sh chmod 0755 get_container_cloud.sh ./get_container_cloud.sh
Run the following script with the corresponding values of your cluster:
REGIONAL_CLUSTER_NAME=<regionalClusterName> REGIONAL_KUBECONFIG=<pathToRegionalClusterKubeconfig> KUBECONFIG=<mgmtClusterKubeconfig> ./bootstrap.sh destroy_regional
Removing a management or regional cluster using the Container Cloud web UI is not supported.
