This helped me, thank you.
I am looking for a bash script which list the images which are tagged with another version of image. any example?.
Smoove! 👍 thanks
sudo docker ps
? sudo ? You should configure correctly your docker environment...
Is there any way to add each container to an AssociativeArray , seems like it is not looping through them ,
but just returning the list of them as only 1 item. i.e
for container in $containers
do
myArray+=([key]=$container)
done
echo "${#myArray[@]}"
Is just printing the first container
Am I doing something wrong in there ?
Thanks!
Should disable this line in the example or at least make the email an example email
echo $message | mail -s "Docker container $container at $host is out of disk space" "r.sonke@maxxton.com"

Oh haha yes, pretty old script. People even copy pasted it without even modifying and sharing me their monitoring emails....
loved this, thank you.
