/etc/crontabs/docker not found

[senese]

When I am trying to run the image to perform a crontab job on my other running container, I get that message:

NO CONFIG FILE FOUND

crontab generation complete

cat: can't open '/etc/crontabs/docker': No such file or directory

I am using this command to run the container:
docker run -v /var/run/docker.sock:/var/run/docker.sock:ro -v config.yaml:/opt/crontab:rw willfarrell/crontab

It's difficult to debug this because the documention lacks information about this file.

Hi, had the same issue. Doc is indeed not very clear on this.
After fiddling around, got it to work.
The error just means it did not find any config.

So what I did;
mkdir -p /path/crontab/config
mkdir -p /path/crontab/logs

placed a /path/crontab/config/config.json

[{
"schedule":"@every 5m",
"command":"wget -O /dev/null https://google.com"
}]

docker run -d -v /var/run/docker.sock:/var/run/docker.sock:ro -v /path/crontab/config:/opt/crontab:rw -v /path/crontab/logs:/var/log/crontab:rw willfarrell/crontab

files /path/crontab/config/config.working.json and /path/crontab/config/jobs/*.sh will be generated if the config.json was valid.

Hope it helps.
