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
   ```
