The ``ska-tango-base`` helm chart is an application chart which defines the basic TANGO ecosystem in kubernetes.
In specific it defines the following k8s services:
- tangodb: it is a mysql database used to store configuration data used at startup of a device server (more information can be found `here <https://tango-controls.readthedocs.io/en/latest/reference/glossary.html#term-tango-database>`__.
- tangodb: it is a mysql database used to store configuration data used at startup of a device server (more information can be found `here <https://tango-controls.readthedocs.io/en/latest/reference/glossary.html#term-tango-database>`__. If the ``global.operator`` is true then this won't be generated in favour of a databaseds resource type. More information available `here <https://gitlab.com/ska-telescope/ska-tango-operator>`_
- databaseds: it is a device server providing configuration information to all other components of the system as well as a runtime catalog of the components/devices (more information can be found `here <https://tango-controls.readthedocs.io/en/latest/reference/glossary.html#term-tango-host>`__.
- itango: it is an interactive Tango client (more information can be found `here <https://gitlab.com/tango-controls/itango>`__.
- vnc: it is a debian environment with x11 server and vnc/novnc installed on it.

In specific it defines the following helm named template:
- configuration (deprecated): it creates a k8s service account, a role and role binding for waiting the configuration job to be done and a job for the `dsconfig <https://github.com/MaxIV-KitsControls/lib-maxiv-dsconfig>`_ application to apply a configuration json file set into the values file;
- deviceserver (deprecated): it creates a k8s service and a k8s statefulset for a instance of a device server;
- multidevice-config: it creates a ConfigMap which contains the generated `dsconfig <https://github.com/MaxIV-KitsControls/lib-maxiv-dsconfig>`_ json configuration file, the boostrap script for the `dsconfig <https://github.com/MaxIV-KitsControls/lib-maxiv-dsconfig>`_ application and a python script for multi class device server startup;
- multidevice-job: it creates a job for the `dsconfig <https://github.com/MaxIV-KitsControls/lib-maxiv-dsconfig>`_ application to apply a configuration json file set into the values file;
- multidevice-sacc-role: it creates a k8s service account, a role and role binding for waiting the configuration job to be done;
- multidevice-svc: it creates a k8s service and a k8s statefulset for a device server tag specified in the values file.

- deviceserver-pvc: it optionally creates a volume for the deviceserver when it contains the dictionary `volume`. The subkeys are `name`, `mountPath` and `storage`. See example below.
- operator: it creates a k8s DeviceServer type of k8s resources.
With the introduction of the `SKA TANGO Operator k8s controller <https://gitlab.com/ska-telescope/ska-tango-operator>`_ the library is also able to generate DeviceServer type of resources. This can be activate by setting the parameter ``global.operator``.
