error converting YAML to JSON: yaml: line 22: did not find expected key

Question

I am trying to create a redis helm chart via a module within a github workflow. The problem seems to be in the helm-values.yaml file in the module. It's an error converting YAML to JSON: yaml.

I have a workflow in github that executes a command that terraform apply a module that is in another github repo, in this module I have a helm-values.yaml that looks like this:

architecture: standalone

fullnameOverride: ${redis_deployment_name}
auth:
  password: ${redis_admin_password}
# auth:
#   existingSecret: redis
#   existingSecretPasswordKey: redis-password

master:
  ${ indent(2, redis_affinity) }
  ${ indent(2, redis_nodeSelector) }
  ${ indent(2, redis_default_tolerations) }
  persistence:
    enabled: false
  resources:
    limits:
      cpu: 350m
      memory: 700Mi
    requests:
      cpu: 100m
      memory: 256Mi

pdb:
  enabled: true

# Explicit activation of Redis Stream
redisStreamEnabled: true

but I get this error:

 Error: ---> error converting YAML to JSON: yaml: line 19: did not find expected key architecture: standalone

I changed the manifest file to look like this:

## @param architecture; architecture. Allowed: `standalone` or `replication`
##
architecture: standalone

fullnameOverride: ${redis_deployment_name}
auth:
  password: ${redis_admin_password}
# auth:
#   existingSecret: redis
#   existingSecretPasswordKey: redis-password
master:
  ${ indent(2, redis_affinity) }
  ${ indent(2, redis_nodeSelector) }
  ${ indent(2, redis_default_tolerations) }
  persistence:
    enabled: false
  resources:
    limits:
      cpu: 350m
      memory: 700Mi
    requests:
      cpu: 100m
      memory: 256Mi
pdb:
  enabled: true

# Explicit activation of Redis Stream
redisStreamEnabled: true

But now i'm getting this error:

 Error: ---> error converting YAML to JSON: yaml: line 21: did not find expected key ## @param architecture; architecture. Allowed: `standalone` or `replication`

So i changed one more time to this:

---
# Parameter info: architecture. Allowed values: `standalone` or `replication`

architecture: standalone

fullnameOverride: ${redis_deployment_name}
auth:
  password: ${redis_admin_password}
# auth:
#   existingSecret: redis
#   existingSecretPasswordKey: redis-password

master:
  ${ indent(2, redis_affinity) }
  ${ indent(2, redis_nodeSelector) }
  ${ indent(2, redis_default_tolerations) }
  persistence:
    enabled: false
  resources:
    limits:
      cpu: 350m
      memory: 700Mi
    requests:
      cpu: 100m
      memory: 256Mi

pdb:
  enabled: true

# Explicit activation of Redis Stream
redisStreamEnabled: true

But now I get this error:

 Error: ---> error converting YAML to JSON: yaml: line 22: did not find expected key ---
│ # Parameter info: architecture. Allowed values: `standalone` or `replication`

Every time I change the code, I get errors related to the first line even if it is a comment. I used **yamllint **to verify, the code works locally when i don't call it as a module, when i do a terraform apply directly in the root module. What seems to be the problem?

This is the code of the terraform module:

resource "helm_release" "redis" {
    timeout   = 240
    name      = "redis"
    namespace = var.namespace
    chart     = "oci://registry-1.docker.io/bitnamicharts/redis"
    version   = var.helm_chart_version
    values = [templatefile("${path.module}/manifests/redis-values.yaml", {
      redis_deployment_name     = var.redis_deployment_name
      redis_affinity            = var.redis_affinity
      redis_nodeSelector        = var.redis_nodeSelector
      redis_default_tolerations = var.redis_default_tolerations
      redis_admin_password      = var.redis_admin_password
    })]
}

and this is how I'm calling it:

module "redis" {
    source = "git::https......"
    namespace                 = var.namespace
    redis_deployment_name     = var.redis_deployment_name
    redis_affinity            = var.redis_affinity
    redis_nodeSelector        = var.redis_nodeSelector
    redis_default_tolerations = var.redis_default_tolerations
    redis_admin_password      = "toto"
}

These are screenshots from the outout of the github workflow:

Answer 1

I had to remove all the commented code and use yamllint to validate the code.
