Schedule doesn`t start from command line

[yuturiy]

I use
dagster schedule start --start-all
inside docker container for script in docs https://dagster.readthedocs.io/en/0.6.0.post0/sections/learn/tutorial/scheduler.html

Dockerfile:

FROM python:3.7.4-slim-stretch

RUN apt-get update
RUN apt-get -y install cron 

RUN pip install dagster
RUN pip install dagit
RUN pip install dagster-cron

WORKDIR /dagster

EXPOSE 3000

ENTRYPOINT [ "dagit", "-h", "0.0.0.0", "-p", "3000" ]

docker-compose.yml

version: '3'
services:
  dagster:
    build: .
    environment:
      - LC_ALL=C.UTF-8
      - LANG=C.UTF-8
    ports:
      - 3000:3000
    volumes:
      - ./dagster:/dagster

And get

I believe this will be fixed by https://dagster.phacility.com/D1226

one workaround you can use in the interim:

for name in `dagster schedule list --name`; do
    dagster schedule start $name;
done

also @helloworld I think we're going to have to update the docs to describe how to get cron working in a container, the above Dockerfile won't launch cron. @newturok FYI you'll need something like the following in an entrypoint.sh:

#!/bin/sh

# see: https://unix.stackexchange.com/a/453053 - fix link-count
touch /etc/crontab /etc/cron.*/*

service cron start
export DAGSTER_HOME=/opt/dagster/dagster_home

for name in `/usr/local/bin/dagster schedule list --name --running`; do
    echo $name;
    /usr/local/bin/dagster schedule stop $name;
    /usr/local/bin/dagster schedule start $name;
done

/usr/local/bin/dagit -h 0.0.0.0

then in your Dockerfile, add the lines:

COPY entrypoint.sh /
ENTRYPOINT ["/entrypoint.sh"]

Maybe I don't understand something, but it looks like cron is not installed in Docker image, at least dagster/dagster-py37

Only after

RUN apt-get update
RUN apt-get -y install cron 

in Dockerfile i get

@natekupp
dagster schedule up is needed to start from scratch
