Deploy a Redis cluster on GKE

Objectives

This tutorial covers the following steps:

Create a GKE cluster.
Create a Redis Cluster on GKE.
Confirm the redis is up and running.
Confirm creation of the volumes for the stateful set.
Confirm the Pod Disruption Budget (PDB).

Estimated time:

To get started, click Start.

select/create a project

Create the Autopilot GKE cluster

Change to the autopilot-cluster directory.
```
cd autopilot-cluster 
```
Create a new file terraform.tfvars in that directory.
```
touch terraform.tfvars
```
Open the file for editing.
Paste the following content in the file and update any value as needed.

project_id     = "<walkthrough-project-name/>"
cluster_name   = "cluster"
cluster_create = {
  deletion_protection = false
}
region         = "europe-west1"
vpc_create = { }

Initialize the terraform configuration.
```
terraform init
```
Apply the terraform configuration.
```
terraform apply
```

Fetch the cluster credentials.

gcloud container fleet memberships get-credentials cluster --project "<walkthrough-project-name/>"

Check the nodes are ready.
```
kubectl get pods -n kube-system
```

Install Redis and create associated resources

Change to the patterns/batch directory.
```
cd ../redis-cluster
```
Create a new file terraform.tfvars in that directory.
```
touch terraform.tfvars
```
Open the file for editing.

Paste the following content in the file.

credentials_config = {
  kubeconfig = {
    path = "~/.kube/config"
  }
}
statefulset_config = {
  replicas = 8
  resource_requests = {
    cpu = "1"
    memory = "1.5Gi"
  }
}

Initialize the terraform configuration.
```
terraform init
```
Apply the terraform configuration.
```
terraform apply
```
Check that the Redis pods are ready
```
kubectl get pods -n redis
```
Check that the Redis volumes match the number of replicas
```
kubectl get pv
```
Confirm the Pod Disruption Budget for redis guarantees at least 3 pods are up during a voluntary disruption
```
kubectl describe pdb redis-pdb -n redis
```

Destroy resources (optional)

Change to the patterns/autopilot-cluster directory.
```
cd ../autopilot-cluster
```
Destroy the cluster with the following command.
```
terraform destroy
```

Congratulations

You’re all set!
