 1 | # Unraid_check_docker_script
 2 | Script to troubleshoot what is filling up Unraid docker image
 3 | 
 4 | This script is to help troubleshoot why an Unraid docker image is getting too big.
 5 | 
 6 | The script when run will 
 7 | 1. Show how much total space your Docker images, containers and volumes are taking up.
 8 | 2. Shows how mcuh space each container is taking up (both writable layer and combined read/writable layer size)
 9 | 3. Will list container size in order from highest to lowest size
10 | 4. Shows each docker volume, its size and which container it is connected to
11 | 5. Can be set to remove both orphaned images and unconnected docker volumes when run.
12 | 
13 | 
14 | Usage
15 | 
16 | With user script plugin installed copy and paste script to your Unraid server.
17 | By default script will not remove orpaned images or unconected docker volumes. Set variables to "yes" to have script remove them.
18 | Run script and use it to find out which container or docker image is taking up too much space.
19 | Once you find out what is the culprit check all of your docker mappings for that container. Also check inside the container (a download container like nzbget for example)
20 | that the internal paths are set to a mapped location.
