docker_prune_images: add --all mode for full orphan cleanup
Default still removes only dangling (untagged) images. --all removes stopped containers first, then all images not used by any running container — clears tagged orphan images left behind by removed or stopped apps.

# PURPOSE
|
||||
# ─────────────────────────────────────────────────────────────────────────────
|
||||
# Removes dangling Docker images — images no longer tagged or referenced by any
|
||||
# container. These accumulate after container updates pull a new image version,
|
||||
# leaving the old image behind with no tag.
|
||||
# Removes orphaned Docker images. Two modes:
|
||||
#
|
||||
# Safe to run at any time. Only removes images with no tag and no container
|
||||
# reference — running containers are never affected.
|
||||
# Default — dangling only (safe, fast):
|
||||
# Removes untagged images (no name, no container reference). These accumulate
|
||||
# after container updates pull a new image, leaving the old one untagged.
|
||||
# Running containers are never affected.
|
||||
#
|
||||
# --all — full orphan cleanup:
|
||||
# Step 1: removes stopped containers (exited/created state).
|
||||
# Step 2: removes all images not used by any running container.
|
||||
# Use this to clear tagged images left behind by removed or stopped apps.
|
||||
# CAUTION: also removes intentionally stopped containers — only run when you
|
||||
# know all stopped containers are safe to delete.
