This example configures a redis Resource Definition using Kubernetes Deployment.

Requirements

Name	Version
terraform	>= 1.3.0
humanitec	~> 1.0

Providers

Name	Version
humanitec	~> 1.0

Modules

Name	Source	Version
redis_basic	../../humanitec-resource-defs/redis/basic	n/a

Resources

Name	Type
humanitec_resource_definition_criteria.redis_basic	resource

Inputs

Name	Description	Type	Default	Required
prefix	Prefix of the created resources	string	"hum-rp-redis-ex-"	no

Deploy and use this example

To deploy this resource definition, run these commands below:

git clone https://github.com/humanitec-architecture/resource-packs-in-cluster

cd examples/redis/

humctl login
humctl config set org YOUR-ORG

terraform init
terraform plan
terraform apply

The created Resource Definition can be used in your Score file like illustrated below:

apiVersion: score.dev/v1b1
metadata:
  name: my-workload
containers:
  my-container:
    image: nginx:latest # this container image is just used as an example, it's not talking to redis.
    variables:
      REDIS_CONNECTION_STRING: "${resources.my-redis.host}:${resources.my-redis.port},user=${resources.my-redis.username},password=${resources.my-redis.password}"
resources:
  my-redis:
    type: redis

This Score file when deployed to Humanitec will provision the redis database and inject the outputs in the associated environment variable.

Here is how to deploy this Score file, for example to the redis-example Application and development Environment:

humctl create app redis-example

humctl score deploy \
    -f score.yaml \
    --app redis-example \
    --env development
