Configure authentication for Rancher

We want to connect our Rancher to our GitHub OAuth, once the final Rancher deployment is running.

• Connect Rancher to GitHub OAuth

Add the dependencies to the operations manual

• Network
• Storage
• Servers
• Real things (UPS, ...)

Create the presentation

We have to create a presentation for the project.

• Presentation

Enable monitoring in Rancher

• Activate the Prometheus and Grafana implementation in Rancher

Add authentication to the operations manual

Add GitHub OAuth to the operations manual.

• Add Github OAuth for Rancher
• Add Github OAuth for JupyterHub

Explain the configuration steps in the operations manual

We need to explain precisely how to configure the project.

• Rancher configuration
• JupyterHub configuration
• Longhorn configuration
• Monitoring configuration
• Authentication configuration

Enable TLS

Enable TLS for:

• JupyterHub
• Rancher

Add the members of the group to the operations manual

We need to add the members of the groups to the operations manual and explain their roles in the project.

• Add members
• Define Roles

Writing an introduction to the operations manual

We need to write a introduction to the operation manual, which explains the following key points:

• Why we want to deploy a JupyterHub
• The key components of the project: OpenStack, Kubernetes, Rancher, Longhorn, Monitoring, JupyterHub

Explain the installation in the operations manual

We need to explain the process of installation in the operations manual.

• Installation of Rancher (with the terraform script)
• Installation of Monitoring
• Installation of Longhorn
• Installation of JupyterHub

Add Maintenance to the operations manual

Add a explanation for maintenance tasks in the operations manual.

• Update Rancher
• Update JupyterHub
• Update Longhorn
• Update Monitoring

Add monitoring to the operations manual

• Monitoring
• Surveillance
• Logging
• Reports

Add user groups to the operations manual

Explain user groups in the operations manual.

• Admins of Rancher
• Admins of JupyterHub
• Users of the JupyterHub

The JupyterHub must be configured

• Setup authentication with OAuth
• Setup monitoring with Grafana and Prometheus
• Setup ressource managment

Explain trouble shooting in the operations manual

Explain some errors and obstacles we encountered during the deployment process.

• DNS Problems with Rancher on the local network
• Problems with the failing DHCP Server, which resulted in instances not to respond correctly
• The error which triggers upon installation of rancher, which is not problematic
• Instances not to be created correctly, because of errors in the RKE template
• Rancher is unable to connect to instances because of bad configurations in the node template

Setup of backup and restore

• Connect the OpenStack Object Storage with Longhorn, by creating a secret in Rancher
• Verify, that backups can be stored in the Object Storage
• Verify, that backups can be restored

Enable Longhorn as storage provider inside Rancher

We use Longhorn as storage provider, because it provides us with a cloud-native storage solution.

• Activate Longhorn
• Verify, that we have at least 3 nodes running to achieve resilience

Add the architecture to the operations manual

We need to explain the basic architecture of our project in the operations manual.
The following components have to be shown:

• JupyterHub
• Rancher (Kubernetes)
• Longhorn (Storage)
• Prometheus and Grafana (Monitoring)
• OAuth (Authorization)
• OpenStack Loadbalancer (Ingress for JupyterHub)
• OpenStack Object Storage (Backup)
• VMs for the Kubernetes Cluster
• Grafana Loki
• Slack

Explain scaling,reliability and security

• Scaling
• Reliability
• Security

Add backup and restore to the operations manual

Add detailed instructions for backup and restore to the operations manual.

• Describe Backup
• Describe Restore

Setup Rancher on OpenStack

We need to setup Rancher to have a running Kubernetes cluster to deploy our JupyterHub.

• Modify the existing terraform script to meet the requirements of our project
• Activate the OpenStack Node Driver
• Create a node template for OpenStack
• Create a RKE template for OpenStack

Add TLS to documentation

Add TLS to the security and configuration part of the documentation.

• JupyterHub
• Rancher
