Redis pod labeler is a simple tool that label the pods of redis-ha cluster (with sentinel) with their role. Written in simple python3 script.

  • This is help to determine which pod is master/ slave
  • Useful when exposing redis master/ slave
  • By default it creates a service that expose the redis master

This chart deploys a small pod and create service account with required privileges to run and update the labels of redis pods. Its just a simple tool that can be run on your namespace as same as your redis namespace.


helm install hmdmph/redis-pod-labeler \
     --name redis-labeler \
     --set namespace=redis \
     --set headlessName=my-redis-redis-ha \
     --set \
     --set redisPodSelector.keyValuePair="release=my-redis"  \
     --set verbose.enabled=true

Above will install the redis-pod-labeler in the namespace of redis. It will find the redis-ha announce services using label release=my-redis and the given headless name my-redis-redis-ha then label them with roles with key/value

Prerequisites / Dependencies

$ helm repo add hmdmph
$ helm install hmdmph/redis-pod-labeler \
       --name redis-labeler \
       --set namespace=redis \
       --set headlessName=my-redis-redis-ha \
       --set \
       --set redisPodSelector.keyValuePair="release=my-redis"  \
       --set verbose.enabled=true

This Helm chart deploys redis-pod-labeler on the Kubernetes cluster in a default configuration. The configuration section lists the parameters that can be configured during installation.

  • Improved docker alpine based small image.
  • Fixed a bug when deploying in multiple redis environments.


  • This is the initial version of the redis-pod-labeler chart with the minimal configuration/ settings.
