What Problem Does This Solve?

When deploying a Redis cluster, we often need to include a proxy component. However, most Redis charts do not come with a proxy component. To address this, I created a Helm chart using Predixy as the proxy.

What Has Been Done?

1. Developed a Predixy Helm chart.
2. Combined the Predixy chart with the redis 20.6.1 · bitnami/bitnami into a unified chart.
3. This combination allows deploying both Predixy and Redis Cluster via a single helm install command. After deployment, the architecture looks as follows:

How to Use It?

1. Deploy Predixy Separately

1. Create a **value.yaml** file

Configure the storageClass and passwords for both the Redis cluster and Predixy. Ensure they are set independently:

global:
  redis:
    password: "" 
  predixy:
    clusterServerPool:
      password: "" 
  storageClass: ""

2. Install the Chart

Use the following command to install Predixy:

helm -n redis-cluster install predixy predixy -f value.yaml

2. Deploy Predixy and Redis Cluster Together

1. Modify the **value.yaml** file

When deploying both components together, include the fullnameOverride field to prevent naming conflicts. Both subcharts use the release name to generate container names and other values. Without overriding this, deployment may lead to naming issues.

global:
  redis:
    password: ""
  predixy:
    clusterServerPool:
      password: ""
  storageClass: ""

redis-cluster:
  fullnameOverride: ""
predixy:
  fullnameOverride: ""
  clusterFullNameOverride: ""#Consistent with redis-cluster.fullnameOverride

2. Install the Chart

Deploy both Predixy and Redis Cluster together using:

helm -n redis-cluster install redis-cluster-predixy ./redis-cluster-predixy

Shortcomings

1. Duplicate Dependencies:
   Both the Predixy and Redis Cluster charts use a shared common chart. Currently, each includes its own copy. This should be refactored to share a single instance of the common chart.
2. Startup Sequencing:
   When deploying together, Predixy should wait for the Redis Cluster to be fully initialized before starting.
3. Incomplete Files:
   Some files, such as NOTES.txt and configurations for ingress, are missing and need to be completed.
4. Prometheus Integration:
   The Redis Cluster chart supports Prometheus integration, but this has not yet been added to Predixy.
