How to correctly inject config?

[Andrew-Cha]

Hi, I am also not able to monitor my workers (the error above is identical).

In docker container "My Celery Worker" the celery workers are configured to serialize over pickle.
In another docker container "My Flower Monitoring" the celery flower lives (using the official image).

I am unable to match the config of "My Celery Worker" and "My Flower Monitoring" Celery applications.

What is the accepted solution to configure Flower's Celery instance in the official image?

When Pickle Serializer is used in the worker container (Untrusted Content Error)

When the Pickle Serializer is not used in the worker container (Everything works)

so i ran into the same issue with the untrusted content errors today and was able to figure out how to inject the celery config correctly, the --config arg for the celery CLI is actually expecting a python-import-style module for the config and not a file path.

I have a similar setup as @ntarocco with k8s and what you want to do is mount the config map with your celery configuration at the path of the docker container where celery/flower is being invoked, and then pass just the file name (without the .py extension) to the --config arg.

Here's my k8s deployment/configmap specs from my working setup for reference:

apiVersion: v1
kind: ConfigMap
metadata:
  name: celery-config
data:
  celeryconfig.py: |
    accept_content = ['application/x-python-serialize', 'application/json']
---
apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: flower
  name: flower
spec:
  replicas: 1
  selector:
    matchLabels:
      app: flower
  template:
    metadata:
      labels:
        app: flower
    spec:
      containers:
      - name: flower
        image: mher/flower:2.0.1
        command:
        - "celery"
        args:
        - "--config=celeryconfig"
        - "flower"
        env:
        - name: CELERY_BROKER_URL
          value: <your_broker_url>
        ports:
        - containerPort: 5555
          protocol: TCP
        volumeMounts:
        - mountPath: /data # path where celery/flower is being invoked in the docker container
          name: flower-config
      volumes:
      - configMap:
          name: flower-config
        name: flower-config
