Django Helm Chart with Celery, Celery-Beat, Flower and Redis. The chart also includes deployments for Celery setup (Worker, Flower.

• Deployment includes a multi container pod with Django and Caddy. Caddy is used as sidecar to serve the static files of backend. Caddyfile can be found here.

• The chart includes Redis as an optional subchart.

• The Deployment containers init containers for migrations and staticfiles.

This is my personal take on such a type of chart, thus I might not use the best practices or you might disagree with how I do things. Any and all feedback is greatly appreciated!

Set values for Django backend on Deployment Section of values.yaml

Example:

replicaCount: 1
revisionHistoryLimit: 2
image:
  repository: ghcr.io/sanoguzhan/django-helm-test
  pullPolicy: IfNotPresent
  # Overrides the image tag whose default is the chart appVersion.
  tag: "latest"
  containerPort: 8081
command: 'gunicorn blog.wsgi -b 0.0.0.0:8081'

Note: Set the command as a string instead of a list.

• migrations: Add command to apply migrations before container is created.
• staticfiles: Add command for Django to collect static files.

init:
  migrations:
    name: migrations
    command:  "python3 manage.py migrate"
  staticfiles:
    name: staticfiles
    command: "python3 manage.py collectstatic --noinput"

Static files and Media directories should be given under data:

data:
  staticfiles: "app/staticfiles/"
  data_media: "app/data_media/"

Paths should be relative to the working directory of main container. Static files are shared volume (emptyDir) between initContainer and Proxy container.

ConfigMaps and Secret values should be set under:

# Env ConfigMap values 
envConfigs: {}
# Enc Secret Values (Base64 encoded data)
envSecrets: {}

Celery setup includes worker, flower and beat. Celery Beat is optional, set enabled to false if you want to exclude it. Flower includes ingress setup optionally.

celery:
# Celery Beat Values
  beat:
    enabled: true
    componentName: celery-beat
    command: 'celery -A blog.celery beat -l DEBUG'
    replicaCount: 1
    strategy: Recreate
# Celery Worker Settings  
  worker:
    componentName: celery-worker
    command: 'celery -A blog.celery worker -l DEBUG'
    replicaCount: 1
    strategy: RollingUpdate
# Celery Flower Settings
  flower:
    componentName: celery-flower
    command: 'celery -A blog.celery flower'
    replicaCount: 1
    strategy: RollingUpdate   
    service:
      type: ClusterIP
      port: 
        number: 5555
        name: flower
    ingress:
      enabled: false
      annotations: {}
      hosts:
        - host: example.com
          paths:
            - path: / 
              pathType: Prefix
      tls: []  

Redis is optional sub-chart, which could be disabled by setting enabled to false. Bitnami Redis Helm Chart is used, and version of the chart is given in the Chart.yaml file.

redis:
  enabled: true
