Redis Cache Operator

Resources Supported

The RedisCache operator suite consists of the following operators.

  1. Redis Cache - Deploys an Azure Cache for redis into a specified resource group at the specified location
  2. Redis Cache Firewall Rule - Deploys a firewall rule to allow access to the RedisCache from the specified IP range

RedisCache

Learn more about Azure Cache for Redis here.

Here is a sample YAML to provision an Azure Cache for Redis.

The spec is comprised of the following fields:

  • Location
  • ResourceGroupName
  • Properties
    • SKU
      • Name
      • Family
      • Capacity
    • EnableNonSslPort
    • SubnetID
    • StaticIP
    • Configuration
  • SecretName
  • KeyVaultToStoreSecrets

Required Fields

A Redis Cache needs the following fields to deploy, along with a location and resource group.

  • Properties.SKU.Name Select a SKU, where the options are: Basic, Standard, and Premium.
  • Properties.SKU.Family Select a SKU Family, where the options are: C, P. If you selected a Premium SKU, then the corresponding SKU Family is P.
  • Properties.SKU.Capacity Set the desired capacity
  • EnableNonSslPort defaults to True

Optional Fields

  • SecretName specify the name of the secret. If none is given, it will fall back to the name of the redis cache.
  • KeyVaultToStoreSecrets specify a Key Vault to store primary and secondary credentials in. If none is given, it will default to storing credentials as a Kube Secret.
  • Properties.SubnetID specify a subnet ID to place the Redis Cache in
  • Properties.StaticIP specify a statis IP for the Redis Cache
  • Properties.Configuration specify configuration values as key value pairs for the Redis Cache

Secrets

After creating an Azure Cache for Redis instance, the operator stores a JSON formatted secret with the following fields. For more details on where the secrets are stored, look here.

  • primaryKey
  • secondaryKey

RedisCache firewall rule

The RedisCache firewall rule allows you to add a firewall rule to RedisCache.

Here is a sample YAML for RedisCache firewall rule

The redisCache indicates the RedisCache on which you want to configure the new RedisCache firewall rule on and resourceGroup is the resource group of the RedisCache. The startIP and endIP under Properties indicates the IP range of sources to allow access to the RedisCache.

Note: When the startIP and endIP are 0.0.0.0, it denotes a special case that adds a firewall rule to allow all Azure services to access the RedisCache.
