Container instances that run with mutable images, e.g., tagged with `:latest` or similar non-versioned tags, can be upgraded without changing the config. This commit fixes two issues found with this support: - force container image re-fetch on upgrade, even if the file exists locally - surgically remove old image from container store after upgrade Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
=== Container Volume Persistence
ifdef::topdoc[:imagesdir: {topdoc}../../test/case/infix_containers/container_volume]
==== Description
Verify that a container created from a local OCI archive, with a volume
for persistent content, can be upgraded at runtime, without losing the
content in the volume on restart.
==== Topology
image::topology.svg[Container Volume Persistence topology, align=center, scaledwidth=75%]
==== Sequence
. Set up topology and attach to target DUT
. Create container with volume from bundled OCI image
. Verify container has started
. Modify container volume content
. Verify container volume content
. Upgrade container
. Verify container volume content survived upgrade
