Django deploys fail without any real error

I am trying to deploy a Django app to fly and I cannot get past a Failed due to unhealthy allocations error. I am on an M1 Mac, so I’m using --remote-only, and I have bumped the RAM up to 2GB.

The frustrating part is that I’m not seeing much in the way of errors. In the logs I see:

2022-05-28T14:30:31.428 runner[09695539] yyz [info] Starting virtual machine

2022-05-28T14:30:32.859 app[09695539] yyz [info] Starting clean up.

If anyone has any tips to at least get to a useful error output, I would be most grateful - TIA!

My Dockerfile:

FROM python:3.9

ENV PYTHONUNBUFFERED=1
ENV PYTHONDONTWRITEBYTECODE 1

# For node
RUN curl -sL https://deb.nodesource.com/setup_14.x | bash -
RUN apt-get update

# For webpack (to generate bundles)
RUN apt-get install nodejs -y

# Setup workdir
RUN mkdir /src
WORKDIR /src

# JS dependencies
COPY package.json /src/
RUN npm install

# Python dependencies
COPY requirements.txt /src/
RUN pip install -r /src/requirements.txt

COPY . /src

And my fly.toml:

# fly.toml file generated for bears on 2022-05-28T07:32:02-04:00

app = "bears"

kill_signal = "SIGINT"
kill_timeout = 5
processes = []

[build]
  dockerfile = "Dockerfile"

[env]

[experimental]
  allowed_public_ports = []
  auto_rollback = true

[[services]]
  http_checks = []
  internal_port = 8000
  processes = ["app"]
  protocol = "tcp"
  script_checks = []

  [services.concurrency]
    hard_limit = 25
    soft_limit = 20
    type = "connections"

  [[services.ports]]
    force_https = true
    handlers = ["http"]
    port = 80

  [[services.ports]]
    handlers = ["tls", "http"]
    port = 443

  [[services.tcp_checks]]
    grace_period = "1s"
    interval = "15s"
    restart_limit = 0
    timeout = "2s"

Doh - just realized there is no CMD at the end of my Dockerfile, the command exists in my docker-compose.yml file.
