You can install, update, or remove KUMA components by changing to the directory with the extracted kuma-ansible-installer and using the Ansible tool and a prepared inventory file. You can specify KUMA configuration settings in the inventory file; the installer then uses these settings when deploying, updating, and removing the application. The inventory file must conform to the YAML format.
You can create an inventory file based on the templates included in the distribution kit. The following templates are provided:
single.inventory.yml.template can be used when installing KUMA on a single server. This template contains the minimum set of settings optimized for installation on a single device without using a Kubernetes cluster.
distributed.inventory.yml.template can be used for the initial distributed installation of KUMA without using a Kubernetes cluster, for expanding an all-in-one installation to a distributed installation, and for updating KUMA.
expand.inventory.yml.template can be used in some reconfiguration scenarios, such as adding collector and correlator servers, expanding an existing storage cluster, or adding a new storage cluster. If you use this inventory file to modify the configuration, the installer does not stop services in the entire infrastructure. If you reuse the inventory file, the installer can stop only services on hosts that are listed in the expand.inventory.yml file.
k0s.inventory.yml.template can be used to install or migrate KUMA to a Kubernetes cluster.
We recommend saving a backup copy of the inventory file that you used to install the application. You can use it to add components to the system or remove KUMA.
