helm chart failed installation with values file

Hi, I tried using the following values file:

I used this command to try installing on EKS:
helm install redis-poc ./redis-helm -n redis2

Got following error:

E0707 12:03:06.162690 103515 request.go:1085] Unexpected error when reading response body: net/http: request canceled (Client.Timeout or context cancellation while reading body)

Error: INSTALLATION FAILED: unable to build kubernetes objects from release manifest: unexpected error when reading response body. Please retry. Original error: net/http: request canceled (Client.Timeout or context cancellation while reading body)

Any idea?

[doronl]

OK, had some issue with other Redis Opeartor, after uninstalling it and its CRD (had a RedisCluster CRD as well...) I am getting this error:

Error: INSTALLATION FAILED: unable to build kubernetes objects from release manifest: error validating "": error validating data: [ValidationError(RedisCluster.spec.redisPodSpec.affinity): unknown field "zoneTopologyKey" in com.payu.db.v1.RedisCluster.spec.redisPodSpec.affinity, ValidationError(RedisCluster.spec.redisPodSpec.initContainers): invalid type for com.payu.db.v1.RedisCluster.spec.redisPodSpec.initContainers: got "map", expected "array"]

I took the zoneTopologyKey from the docs

[voltbit]

Hi, I think the docs are a bit old, try the example manifest in here:

https://github.com/PayU/redis-operator/tree/main/config/samples

To see what fields are supported by the redis cluster resource check the CRD definition or look at the definition here:

https://github.com/PayU/redis-operator/blob/main/api/v1/rediscluster_types.go

Also check this section of the README (if you didnt already):

https://github.com/PayU/redis-operator#deploy-via-helm

Thanks, I am working with the section in the readme about trying to install all in helm in the same namespace, below values.yaml file passes installation but opeartor pod can't run because of below errors, seems to be an issue with some configMap (my latest helm values.yaml below)

errors:

_MountVolume.SetUp failed for volume "operator-configuration" : configmap "redis-operator-config" not found

I found this issue, redis-operator-config in the values.yaml should be redis-release-name-operator-config, you need to fix the chart...

[doronl]

as mentione above...
