HOW-TO: Manage WSL Disk Use (Including Podman).md

General guidance for managing WSL space:

• Use ncdu -x to get an overview for disk usage.
• Use podman system df to get an overview for prune savings.
• Delete old, tagged, unwanted images from podman image list w/ podman rmi [imagename].
• Do a podman ps -a and ensure every container to keep features the to-keep label mnemonic for filtering. Workflow to add it follows:

Workflow to add -to-keep label:

1. Commit the [stopped] container

   podman commit container_name container_name-tokeep

2. Rename the existing container so we can use existing --name and test before deleting

   podman rename container_name container_name_old

3. Use inspect to get previous run/create parameters for duplication

   podman inspect --format '{{range .Config.CreateCommand}}{{.}} {{end}}' container_name_old

4. Create or run the NEW '-tokeep' image

   podman create --label to-keep=true [(bind,port,env,--name,etc args from the previous command)] container_name-tokeep /bin/whatever

5. Test

   podman start container_name -ai (or whatever)

6. Delete backup

   podman rm container_name_old

Finally:

• Prune [stopped] containers without our "to-keep" label

  podman container prune --filter "label!=to-keep=true"

• Prune "dangling" images (basically, anything w/o a label)

  podman image prune
