Cleanup Game Resources

This is a destructive operation. Always confirm with the player first.

Step 1: Show What Exists

echo "=== Containers ==="
docker ps -a --filter "label=app=learn-docker-k8s" --format "table {{.Names}}\t{{.Status}}\t{{.Image}}"
echo ""
echo "=== Networks ==="
docker network ls --filter "label=app=learn-docker-k8s" --format "table {{.Name}}\t{{.Driver}}"
echo ""
echo "=== Volumes ==="
docker volume ls --filter "label=app=learn-docker-k8s" --format "table {{.Name}}\t{{.Driver}}"
echo ""
echo "=== Images ==="
docker images --filter "reference=learn-*" --format "table {{.Repository}}:{{.Tag}}\t{{.Size}}"

Step 2: Confirm

Show the player what will be removed and ask for confirmation.

If

$ARGUMENTS

is a specific chapter (e.g., "ch01", "ch03"):

• Only remove resources with the matching chapter label
• Tell them: "I'll only remove Chapter X resources. Everything else stays."

If

$ARGUMENTS

is "all" or empty:

• Run

  bash engine/cleanup.sh

• Also check for kind clusters:

  kind get clusters 2>/dev/null | grep learn

Step 3: Clean

After confirmation, execute the cleanup and report what was removed.

If they're in the middle of a chapter, warn them: "You have in-progress work in Chapter X. Cleaning up means you'll need to redo the challenges. Continue?"

Step 4: Update Progress (if needed)

If cleaning a specific chapter, update

.player/progress.yaml

:

• Reset that chapter's challenges to empty
• Set status back to "in-progress" (keep lesson progress)
