Create cloudflare tunnel helmchart

[gooseops]

Information

• Cloudflare tunnels are a great way for giving origin access without having to open firewalls to the public internet
• There is a container that Cloudflare maintains for deploying the tunnel to containerized environments
• Cloudflare doesn't currently have a supported helm chart to easily deploy their tunnels

Deliverables

• Create a helm chart that runs the cloudflare tunnel container and takes in the different elements/secrets needed for successfully running the cloudflared daemon
• Create a README.md for how to properly deploy the chart using helm and perhaps also terraform

Considerations

• Use Helm best practices
• Create required values so the chart will error if it is improperly configured
• Have the option to set values for the secrets using kubernetes secrets, configmaps, or set blocks.

Possible Next steps

• Add packaging to Github Actions to bundle the helm chart and ship it to a helm registry
• Attempt to get it merged into Cloudflare's opensource repos and determine how to maintain it moving forward
