Miouge1 opened a new issue #49:
URL: https://github.com/apache/couchdb-helm/issues/49
**Is your feature request related to a problem? Please describe.**
When draining a Kubernetes node with `kubectl drain`, several couchdb pods
are sometimes evicted at the same time, resulting in an unavailable couchdb
cluster.
**Describe the solution you'd like**
Adding a `kind: PodDisruptionBudget` option to allow for drain to respect
the disruption budget. For example waiting for the first evicted pod to be
ready before evicting the next one.
**Describe alternatives you've considered**
A clear and concise description of any alternative solutions or features
you've considered.
**Additional context**
Smaller kubernetes clusters are more affected by this since there are more
chances that 2 couchdb pods are scheduled on the same node.
Here is an example of values that this could be controlled with:
```yaml
podDisruptionBudget:
enabled: false
# minAvailable: 1
maxUnavailable: 1
```
