Hi!  
I made docker:  
Dockerfile:  
FROM ruby:2.7

RUN mkdir /usr/src/app  
WORKDIR /usr/src/app

COPY Gemfile Gemfile.lock ./  
RUN gem install bundler  
RUN bundle install

COPY ./ ./  
RUN chmod +x docker-entrypoint.sh

## CMD ["./docker-entrypoint.sh"]

docker-entrypoint.sh

## #!/bin/sh echo 'date.local upload script started at: ’ ( date '+%F %H:%M:%S' ) ruby /usr/local/bundle/gems/ckan\_cli-1.0.2/exe/cli.rb upload -d http://date.local/register.csv -c conf.json -r res.json -w echo 'date.local upload script ended at: ' ( date ‘+%F %H:%M:%S’ ) exit 0;

If I start ./docker-entrypoint.sh to do manually in docher bash or from dockerd docker exec -it date.local ./docker-entrypoint.sh script work well. But I need to made crontab job, and one time in day execute this script. I install cron. I made crontab job:  
20 22 \* \* \* /usr/src/app/docker-entrypoint.sh \>\> /var/log/date.local/`date +\%Y\%m\%d`-date.local.log 2\>&1

But I get the error:  
/usr/src/app/docker-entrypoint.sh: 4: /usr/src/app/docker-entrypoint.sh: ruby: not found

I finded more advice internet, But they not work ☹  
How resolve it?
