[avimoondra]

command:

helm template -f ~/retool-helm/charts/retool/values.yaml foo ~/retool-helm/charts/retool --set config.encryptionKey="foo" --set image.tag="5.6.10" --set codeExecutor.image.tag="5.6.10" --set codeExecutor.enabled=true

values:

codeExecutor:
  # Enable this for Python support and running code more securely within a separate
  # sandboxed environment
  enabled: false

  replicaCount: 1

  # Annotations for code executor pods
  annotations: {}

  # Labels for code executor pods
  labels: {}

  # Config for code executor. Node heap size limits can be overridden here
  config: {}
  # config: {
  #   nodeOptions: --max_old_space_size=1024
  # }
  volumes:
    - name: dsdsocket
      hostPath:
        path: /var/run/datadog/
  volumeMounts:
    - name: dsdsocket
