Docker image file size sanity check (SOLVED)

Featured Replies

Hi all helpful people,

 

It seems that my image file is quite large compare to others when I'm trying to find out what/how/why regarding why my image file was at a critical level. I found that in my case binhex-makemkv was the culprit and that is now deleted. But, I my image file is still large with 40G configured and at 75% full. Still, there is a lot of containers - maybe it's normal?

 

Here is my container size list:

How do this look compared with others?

 

And, what does Writable column actually mean?

 

And again, correct me if I'm wrong. The Container size column is the container itself situated in the docker image file file system, but the log column can be, depending on container and app configuration, situated in the docker image file or typically the appdata share.

 

Thank you in advance for any input

Probably OK as long as the used space isn't growing.

Is this statement true and what is the Writable column? 

The writeable column is extra files the container has written within itself.  ie: In your case it would appear that tdarr is storing intermediate / temporary files within the container.  If this number continues to grow (or grow significantly), then hopefully there's some setting within it (or the template) that will map those temporary files outside of the container to appdata where it belongs

Not a thing that is solved but marking it such now.

Hello. How were you able to get a nice formatted docker log size output like that?

 

UPDATE: I've been reading the DOCKER FAQ's and general use, and it seems that I can probably use the DOCKER command line or execute a command using the docker command. I've used and setup several dockers, not a maniac on having 20 dockers. Just 10 or less and 5 or less are probably running 24/7. I'm gonna keep reading.

Although docker's documentation has a bunch of great info for getting various stats including this one, you can access this report directly in the Unraid GUI like so

Unraid GUI > Docker > Container Size [button]
