Running vault on Kubernetes with Tailscale

Vault
1

Please assume that I know basically nothing about networking.

I followed this tutorial to deploy vault on a kubernetes cluster.

Here is the override-values.yaml file that I used.

server:
  dev:
    enabled: true
  ingress:
    enabled: true
    ingressClassName: "tailscale"
    annotations: {}

As you can see the 2 changes I made is to make it dev and to create a tailscale ingress.

Everything appears to create correctly. When I try and do vault status I get the error:

Error checking seal status: Get "https://<private url>/v1/sys/seal-status": net/http: TLS handshake timeout

When I look at the pod log there are 2 things that stand out to me that don’t make sense.

Listener 1: tcp (addr: "[::]:8200", cluster address: "[::]:8201", max_request_duration: "1m30s", max_request_size: "33554432", tls: "disabled")

and

$ export VAULT_ADDR='http://[::]:8200'

It seems like there should be information populated for the VAULT_ADDR or the listener addr.

I’m not sure where I’m going wrong so any help would be greatly appreciated.
