GKE sslip.io DNS: 1 replica, no readiness
GKE sslip.io DNS: 1 replica, no readiness

We only have 1 node (because I'm frugal), so we really need only one
replica (it's more likely that the node has crashed rather than my
fairly-simple server).

Also, I pushed out the liveness probe to 5 minutes so the logs aren't
cluttered with probes every ten seconds.

I got rid of the readiness probe, which is only for "[applications
[that] are temporarily unable to serve
traffic](https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/)".
It cluttered the logs with its probes. Also my app is never
temporarily unable to serve.

fixes too many occurrences of:
```
