Docker commands in container_commands AWS beanstalk

Question

I am trying to run a .ebextantions/01-main.config with below command. In shell check, it looks fine. But, while executing same getting below error:

container_commands:
  01_cron_job:
    command: docker exec -d -w /var/www/kiu/central "$(docker ps -aqf \"name=kiu-central\")" sh -c \"cat .ebextensions/kuicron.txt > /etc/cron.d/kuicron && chmod 644 /etc/cron.d/kuicron\"
    leader_only: true


Command failed on instance. Return code: 1 Output: Error response from daemon: Invalid filter '"name'
Error: No such container: sh.

Looks like container is not ready while I am executing command — Jaishree Mishra, Oct 28 '19 at 09:49
