Redis Operator by Opstree Installation

Redis Operator by OpsTree is a Redis operator that will make/oversee Redis standalone and cluster mode setup on top of Kubernetes.

Installation

1. Connect to 🟢 Management Kubernetes Cluster ; _i.e w/ Kubeconfig File.

   Set Kubeconfig File

   Ensure you have defined and loaded your Global Shell Variables as described in Shell Variables.

   source $HOME/opstella-installation/shell-values/kubernetes/management_cluster.vars.sh

   export KUBECONFIG="$HOME/opstella-installation/kubeconfigs/management_cluster.yaml"

2. Create Namespace for Redis Operator Controller

   2.1 Create Kubernetes Namespace

   kubectl create namespace ot-operators

3. Add Operator Helm Repository

   helm repo add ot-helm https://ot-container-kit.github.io/helm-charts/

4. Create Helm Values Configurations for Operator

   cat <<EOF > $HOME/opstella-installation/helm-values/ot-redis-full-values.yaml
   ---
   redisOperator:
     # If set to true, webhook server will be enabled for masterSlaveAntiAffinity feature
     # When enabled, you need to either:
     # 1. Enable cert-manager (certmanager.enabled=true) for automatic certificate management, or
     # 2. Manually create a certificate secret (see "How to generate private key" section in README)
     webhook: true
   
   issuer:
     # Whether to create the issuer or not. You might want to disable this if instead you
     # want to use a ClusterIssuer that you simply want to provide.
     create: true
     # You can choose Issuer or ClusterIssuer here. The first one is namespaced, the second one
     # is available for global usage.
     kind: Issuer
     type: selfSigned
     name: redis-operator-issuer
     email: ""
     server: ""
     privateKeySecretName: ""
     solver:
       enabled: false
   
   certmanager:
     # Whether to use cert-manager for certificate management
     # Only effective when webhook=true
     # If webhook=true and certmanager.enabled=false, you need to manually create certificate secret
     enabled: true
   
   podSecurityContext:
     fsGroup: 1000
   
   securityContext:
     runAsUser: 1000
     runAsGroup: 1000
     runAsNonRoot: true
     privileged: false
     allowPrivilegeEscalation: false
     seccompProfile:
       type: RuntimeDefault
     capabilities:
       drop: ["ALL"]
   
   # Feature gates for alpha/experimental features
   featureGates:
     # Enable generating Redis configuration using an init container instead of a regular container
     GenerateConfigInInitContainer: true
   EOF

5. Install Redis Operator

   helm install redis-operator ot-helm/redis-operator --namespace ot-operators \
       -f $HOME/opstella-installation/helm-values/ot-redis-full-values.yaml
