Charts: [stable/redis] Incompatible types for equality comparison

[sebnyberg]

After upgrading to Helm 2.15, the chart (v9.3.2) is throwing an error regarding the EQ operator at
https://github.com/helm/charts/blob/master/stable/redis/templates/redis-master-statefulset.yaml#L81

Error:

Error: render error in "redis/templates/redis-slave-statefulset.yaml": template: redis/templates/redis-slave-statefulset.yaml:87:18: executing "redis/templates/redis-slave-statefulset.yaml" at <eq .Values.securityContext.runAsUser 0.0>: error calling eq: incompatible types for comparison

To try it out, simply run:

helm install stable/redis

Thanks for reporting the issue, it seems something change in Helm v2.15, and there are some issues already open: https://github.com/helm/helm/issues/6708

We will take a look and investigate it properly, coming back with an answer.

Same error:

Hi, a new version of Helm was released yesterday (2.15.1). Among other fixes, it includes:

• Reverted changes introduced in https://github.com/helm/helm/pull/6010

Can you confirm if the issue is solved using the new Helm version?

[tomjohnburton]

Still unresolved unfortunately.

I ran the update

▶ helm version
Client: &version.Version{SemVer:"v2.15.1", GitCommit:"cf1de4f8ba70eded310918a8af3a96bfe8e7683b", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.15.1", GitCommit:"cf1de4f8ba70eded310918a8af3a96bfe8e7683b", GitTreeState:"clean"}

Followed by attempting to install

 helm install stable/redis --values values.yaml --name redis --namespace default                  
Error: render error in "redis/templates/redis-slave-statefulset.yaml": template: redis/templates/redis-slave-statefulset.yaml:87:18: executing

[tomjohnburton]

Hangon! I just realised that I hadn't set the securityContext in both the slave and master configuration.

  ## Redis Master Pod Security Context
  ##
  securityContext:
    enabled: true
    fsGroup: 1001
    runAsUser: 1001

  # Redis slave pod Security Context
  securityContext:
    enabled: true
    fsGroup: 1001
    runAsUser: 1001

Same issue for anchore-engine on e helm v2.15.1

  Error: render error in "anchore-engine/templates/engine_configmap.yaml": template: anchore-engine/templates/engine_configmap.yaml:156:15: executing "anchore-engine/templates/engine_configmap.yaml" at <gt .Values.anchoreAnalyzer.layerCacheMaxGigabytes 0.0>: error calling gt: incompatible types for comparison

I just tried using Helm 2.15.1 and the issue seems to be solved:

$ helm version
Client: &version.Version{SemVer:"v2.15.1", GitCommit:"cf1de4f8ba70eded310918a8af3a96bfe8e7683b", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.15.1", GitCommit:"cf1de4f8ba70eded310918a8af3a96bfe8e7683b", GitTreeState:"clean"}

take into account that Helm is upgraded in both sides, client and server, for that, I downloaded the new Helm version from the official GH repository and install the binary. After that, I upgraded Tiller with helm init --upgrade.

Using this new version I installed Redis by running

$ helm repo update
$ helm install stable/redis

and everything works as expected:

$ kubectl get pods
NAME                                        READY   STATUS              RESTARTS   AGE
funky-sloth-redis-master-0                  1/1     Running            0          10m27s
funky-sloth-redis-slave-0                   1/1     Running            0          10m27s
funky-sloth-redis-slave-1                   1/1     Running            0          10m

I think this issue can be considered solved. If you have other unrelated issues or issues with other charts, please, open a new issue to avoid mixing topics.

Helm init and updated. Problem not solved.

According to your output, you are still using helm v2.15.0, please update it to v2.15.1 in client and server.

Please, can you create another issue for stable/anchore-engine? This thread is focused on stable/redis

I am on helm 2.15.1 and seeing this issue

[theshizzah]

Ah, upgraded my helm server to 2.15.1 to match and that seemed to fix it

[sebnyberg]

Resolved for me too. Closing issue.

[ledroide]

I confirm the "incompatible types for comparison" issue with Tiller v2.15.0.
Upgrading Tiller to v2.15.1 solves the problem for me.

I am facing same issue with helm 2.16.0

Can you run $ helm version and paste here the output?

[patvdleer]

v3.0.0 seems to have the issue as well https://github.com/helm/helm/issues/7023
