Helm repository

Add the Helm repository:

helm repo update

Base install

The Base install will create ServiceAccount, Role, Namespace, and RBAC objects needed to place the Skaha service.

Create a my-base-local-values-file.yaml file to override Values from the main template values.yaml file. Mainly the Traefik Default Server certificate (optional if needed):

my-base-local-values-file.yaml

secrets:
    default-certificate:
        tls.crt: <base64 encoded server certificate>
        tls.key: <base64 encoded server key>
helm install --values my-base-local-values-file.yaml base science-platform/base

NAME: base
LAST DEPLOYED: Thu Sep 28 07:28:45 2023
NAMESPACE: default
STATUS: deployed
REVISION: 1

Persistent Volumes and Persistent Volume Claims

Note The base MUST be installed first as it creates the necessary Namespaces for the Persistent Volume Claims!

Important There are two (2) Persistent Volume Claims that are used in the system, due to the fact that there are two (2) Namespaces (skaha-system and skaha-workload). These PVCs, while having potentially different configurations, SHOULD point to the same storage. For example, if two hostPath PVCs are created, the hostPath.path MUST point to the same folder in order to have shared content between the Services (skaha, cavern) and the User Sessions (Notebooks, CARTA, etc.).

It is expected that the deployer, or an Administrator, will create the necessary Persistent Volumes (if needed), and the required Persistent Volume Claims at this point. There are sample Local Storage Persistent Volume examples in the base/volumes folder.

Required Persistent Volume Claim

It is expected that there is a Persistent Volume Claim with the name of the Skaha Workload namespace hyphenated with cavern-pvc. This will provide the backing storage to the User Sessions. Using the default values, this means:

skaha-workload-cavern-pvc

will exist as a Persistent Volume Claim in the skaha-workload namespace.

POSIX Mapper install

The POSIX Mapper Service is required to provide a UID to Username mapping, and a GID to Group Name mapping so that any Terminal access properly showed System Users in User Sessions. It will generate UIDs when a user is requested, or a GID when a Group is requested, and then keep track of them.

This service is required to be installed before the Skaha service.

Create a my-posix-mapper-local-values-file.yaml file to override Values from the main template values.yaml file.

User Storage UI installation

Create a my-storage-ui-local-values-file.yaml file to override Values from the main template values.yaml file.
