Redis HA¶

In this Document we will cover installing the Redis Server and Redis Haproxy, due to the k8s-resources configurations both would be installed and configured inside the prod namespace.

Prerequisites

Make sure to create a values.yaml and replace add your credentials

values.yaml Overrides the PersistentVolume, adds secrets and uses openebs as storage class.

## replicas number for each component
replicas: 3

persistentVolume:
  enabled: true
  ## redis-ha data Persistent Volume Storage Class
  ## If defined, storageClassName: <storageClass>
  ## If set to "-", storageClassName: "", which disables dynamic provisioning
  ## If undefined (the default) or set to null, no storageClassName spec is
  ##   set, choosing the default provisioner.  (gp2 on AWS, standard on
  ##   GKE, AWS & OpenStack)
  ##
  storageClass: openebs-hostpath

## Sentinel specific configuration options
sentinel:
  auth: true
  authkey: <AUTH-KEY>
  password: <PASSWORD>

## Redis specific configuration options
auth: true
authkey: <AUTH-KEY>
redisPassword: <PASSWORD>

Redis Server & Sentinel¶

# add helm repo
helm repo add dandydev https://dandydeveloper.github.io/charts
helm repo update

## deploy redis servers for prod env
helm upgrade --install --namespace prod redis-ha dandydev/redis-ha --values values.yaml

## deploy redis server for discover env
# helm upgrade --install --namespace discover redis-ha dandydev/redis-ha --values values.yaml

Redis Haproxy¶

Preq¶

Make sure to load the configs/secrets see also k8s-resources

Deploy redis-haproxy¶

## deploy for prod env
kubectl apply -n prod -f resources/deployments/redis-haproxy.yml

## deploy for discover env
# kubectl apply -n discover -f resources/deployments/redis-haproxy.yml
