Create and Configure Helm Charts

[aprilrieger]

Estimate of 12 total hours to create helm charts for ucla oh’s blacklight application, including 2 hours to create documentation and 2 hours for pairing with the client to integrate with Argo CD and their applications micro services.

Currently the client is using existing shared postgres, and a stand alone, un-shared Solr VM that we will need to connect the deployment to.

• Note: They would like to migrate over to a fully containerized approach and they have no chart preference to note. When they are ready I would suggests that

They currently use HAProxy as a TLS endpoint, which handles the public-facing certificates.

The storage class we will be utilizing is vSphere CSI https://docs.vmware.com/en/VMware-vSphere-Container-Storage-Plug-in/3.0/vmware-vsphere-csp-getting-started/GUID-6DBD2645-FFCF-4076-80BE-AD44D7141521.html https://github.com/kubernetes-sigs/vsphere-csi-driver

UCLA OH’s secrets strategy is external secrets for this deployment setup. https://external-secrets.io/latest/

Scope:

Create helm charts for UCLA Oral History’s Blacklight application.

These charts will be used in deployments to a Rancher managed Kubernetes cluster through the continuous integration tool ArgoCD. We will be tapping into an existing, shared, Postgres database and a stand-alone Solr VM. We will be using vSphere CSI for the storageClass for the application’s PVCs. The secret strategy we will be using for this application is existing-secrets, and we will be using HAProxy as a TLS endpoint to handle the public-facing certificates for the site.

We will also be including basic helm chart documentation and how to use the helm chart’s values file in a dev workflow.

Provide 2 hours of pairing time to help staff integrate helm charts with pre-existing infrastructure.

Summary

Looking forward, UCLA Library will be decommissioning threir Docker Swarm environment and migrating all existing hosted applications to a Rancher managed Kubernetes cluster. They'll be using Argo CD with helm charts to manage the deployments.

Acceptance Criteria

• [ ] Create Helm Charts for UCLA OH's Blacklight Application
• [ ] Add default values for them to use in configuring to their needs.
• [ ] Be available to the team for a 2 hour pairing block to help configure with exisiting microservices
• [ ] Create basic helm chart documentation and outline how to use the values file in a dev workflow for deployments.
