# Helm Chart for Wekan
## Features
o Uses a MongoDB replica set by default - this allows fault-tolerant
and scalable MongoDB deployment (or just set the replicas to 1 for
a single server install)
o Optional Horizontal Pod Autoscaler (HPA), so that your Wekan pods
will scale automatically with increased CPU load.
## The configurable values (values.yaml)
Scaling Wekan:
```yaml
## Configuration for wekan component
##
replicaCount: 1
```
**replicaCount** Will set the initial number of replicas for the Wekan pod (and container)
```yaml
## Configure an horizontal pod autoscaler
##
autoscaling:
enabled: true
config:
minReplicas: 1
maxReplicas: 16
## Note: when setting this, a `resources.request.cpu` is required. You
## likely want to set it to `1` or some lower value.
##
targetCPUUtilizationPercentage: 80
```
This section (if *enabled* is set to **true**) will enable the Kubernetes Horizontal Pod Autoscaler (HPA).
**minReplicas:** this is the minimum number of pods to scale down to (We recommend setting this to the same value as **replicaCount**).
**maxReplicas:** this is the maximum number of pods to scale up to.
**targetCPUUtilizationPercentage:** This is the CPU at which the HPA will scale-out the number of Wekan pods.
```yaml
mongodb-replicaset:
enabled: true
replicas: 3
replicaSetName: rs0
securityContext:
runAsUser: 1000
fsGroup: 1000
runAsNonRoot: true
```
This section controls the scale of the MongoDB redundant Replica Set.
**replicas:** This is the number of MongoDB instances to include in the set. You can set this to 1 for a single server - this will still allow you to scale-up later with a helm upgrade.
### Install OCP route
If you use this chart to deploy Wekan on an OCP cluster, you can create route instead of ingress with following command:
``` bash
$ helm template --set route.enabled=true,ingress.enabled=false values.yaml . | oc apply -f-
```
