Run a command on all docker containers

runCommandAllDockers.sh

for container in `docker ps -q`; do 
  # show the name of the container
  docker inspect --format='{{.Name}}' $container;
  # run the command (date in the case)
  docker exec -it $container date;
done

If you replace "date" or "bash -c 'rm -rf /app/Log*'" with $1, you can pass the desired command into the script:

for container in `docker ps -q`; do 
  # show the name of the container
  docker inspect --format='{{.Name}}' $container;
  # run the command (date in the case)
  docker exec -it $container $1;
done

Examples:

• ./runCommandAllDockers.sh "some command here"
• ./runCommandAllDockers.sh "du -h /var/log"

Hint: Wrap your command in double-quotes so the script sees it as one parameter.
