Create a Redis service

Apply the following object on your namespace, as specified by its YAML description.

Example to create a Redis instance

apiVersion: vshn.appcat.vshn.io/v1
kind: VSHNRedis
metadata:
  name: redis-app1-prod (1)
  namespace: prod-app (2)
spec:
  parameters:
    service:
      version: "7.0" (3)
      redisSettings: | (4)
        activedefrag yes
    size: (5)
      plan: standard-2
  writeConnectionSecretToRef:
    name: redis-creds (6)

1	Instance name
2	The namespace where the object will be created
3	Redis version
4	Specify custom Redis settings [optional]
5	Size of the Redis instance. See Plans and Sizing for more information.
6	Secret where the connection details are provisioned. This secret shouldn’t exist before creation.

To get more information about all available configuration options, please see the API Reference

Inspect your new Redis service

$  oc get vshnredis.vshn.appcat.vshn.io
NAME              SYNCED   READY   CONNECTION-SECRET   AGE
pgsql-app1-prod   True     True    redis-creds         3m32s

When you see True in the READY column, it means the instance is provisioned and ready to use.

Find the connection details

The connection details are stored in a secret. You can retrieve them with the following command:

$ oc get secrets redis-creds -o yaml

The output of the command above is a secret specification with the following structure:

apiVersion: v1
kind: Secret
metadata:
  name: redis-creds
stringData:
  REDIS_HOST: 127.0.0.1 (1)
  REDIS_PASSWORD: my-secret (2)
  REDIS_PORT: 21700 (3)
  REDIS_URL: rediss://default:my-secret@127.0.0.1:21700 (4)
  REDIS_USERNAME: default (5)
  ca.crt: base64encoded(data) (6)
  tls.crt: base64encoded(data) (7)
  tls.key: base64encoded(data) (8)

1	Host to connect to
2	Password
3	Port to use
4	URL containing all necessary information to connect to the instance
5	Username
6	CA certificate to use when TLS is enabled
7	Certificate to use when TLS is enabled
8	Key to use when TLS is enabled
