Failed deploy after pushing image to registry

Hi!

I’m trying to deploy my dockerized django app to render but it keeps failing.

The following is my render.yaml

#render.yaml
services:
  - type: web
    name: listikles
    env: docker
    region: oregon 
    plan: free 
    branch: master 
    dockerCommand: python manage.py collectstatic --no-input && python manage.py tailwind build && python manage.py runserver 0.0.0.0:8000
    numInstances: 1 
    healthCheckPath: /
    envVars:
      - key: DEBUG
        value: True

And that is the correct heroku.yml that I am trying to translate to render:

# heroku.yml
setup:
  addons:
  - plan: heroku-postgresql
build:
  docker:
    web: Dockerfile
release:
  image: web
  command:
    - python manage.py collectstatic --noinput
run:
  web: gunicorn config.wsgi

I don’t know what’s going on, I tried to put a script “build.sh” in the dockerCommand, but the deploy always fail without error message after pushing to registry.

After some tinkering, turns out my dockerCommand was wrong.

I didn’t catch that it is the CMD of a Dockerfile.
It ‘works’ with dockerCommand: gunicorn project.wsgi .

So my question is, where do I put those:
python manage.py migrate
python manage.py tailwind build
python manage.py collectstatic --no-input

The answer was…

#Dockerfile
...
RUN SECRET_KEY=nothing python manage.py tailwind install --no-input;
RUN SECRET_KEY=nothing python manage.py tailwind build --no-input;
RUN SECRET_KEY=nothing python manage.py collectstatic --no-input;
...

Before that, I tried with an ENTRYPOINT

COPY docker-entrypoint.sh /code/
ENTRYPOINT ["./docker-entrypoint.sh”]
CMD ["gunicorn", "project.wsgi"]

Which worked offline but not on render:

On render, ENTRYPOINT was successfully run, but the subsequent CMD was ignored.
