Crontab won't restart Docker container

I have a container that runs under a Root account which I can start using:

docker start containername

and I want crontab to start it, so as root I used

crontab -e

and set an entry like this:

* * * * * /usr/bin/docker start containername

but it won't work. I also tried

* * * * * root /usr/bin/docker start containername

with no luck.

Anyone has a clue on how I can make this work?

I did it without any problems as follows:

$ crontab -e

then I set a restart for a container every 5 minutes:

*/5 * * * * docker restart <containername>

There are two options.

docker container restart CONTAINER_NAME

docker restart CONTAINER_NAME
  1. sudo crontab -e
  2. 0 1 * * * docker container restart CONTAINER_NAME

You can see with the next command:

sudo crontab -l

Test with Docker version 19.03.6, build 369ce74a3c
