Cluster setup wizards does not work in microk8s

**Describe the bug**
The cluster setup wizard does not work in microk8s, while it does work in k3s, kind, and minikube.

The setup command is
```
curl -s http://127.0.0.1:5984/_cluster_setup -X POST -H "Content-Type: application/json" -d '{"action": "finish_cluster"}' -u admin
```
executed on one of the nodes within k8s, as per the chart's Note.

**Version of Helm and Kubernetes**:
Helm v3.6.3
Kubernetes v1.21.11 (via microk8s)

**What happened**:

```
{"error":"setup_error","reason":"Cluster setup timed out waiting for nodes to connect"}
```

**What you expected to happen**:
Successful completion of setup wizard, creation of `_users` and `_replication` table, etc

**How to reproduce it** (as minimally and precisely as possible):

Install [microk8s](https://microk8s.io/docs/getting-started)
`sudo snap install microk8s --classic --channel=1.21` (you may need more to get kubectl working)

Activate addons for microk8s; `dns` and `storage` are required for this config, `traefik` and `rbac` are also installed for replication
```
microk8s enable dns
microk8s enable storage
```

Install CouchDB [helm chart](https://github.com/apache/couchdb-helm/tree/main/couchdb)
`kubectl create secret generic cluster-couchdb --from-literal=adminUsername=admin --from-literal=adminPassword=dbpass --from-literal=cookieAuthSecret=dbcookiepass --from-literal=erlangCookie=monster`
`helm install my-release couchdb/couchdb --set couchdbConfig.couchdb.uuid=$(curl https://www.uuidgenerator.net/api/version4 2>/dev/null | tr -d -) --version 3.6.1 -f ./values.yaml`
with values.yaml like:
```
createAdminSecret: false

persistentVolume:
enabled: true
accessModes:
- ReadWriteOnce
size: 10Gi
# storageClass: "-"
```
I also did this with version=3.3.3 with same issue.

**Anything else we need to know**:
I tried on two machines, both of which were running Ubuntu 20.04. Between the two machines, I verified that this worked with all of minikube, kind and k3s.
