How to set image label "nerdctl/platform" when commit a container?

[huanghantao]

When I commit a container, it reports:

WARN[0000] Image lacks label "nerdctl/platform", assuming the platform to be "linux/amd64"

However, I don't found a flag to set label.

Please provide a reproducible way, and what is your environment, VM or host?

The command I executed:

nerdctl --namespace k8s.io commit 21761c9464c1 test:v0.0.1
WARN[0000] Image lacks label "nerdctl/platform", assuming the platform to be "linux/amd64"
sha256:ccee20a58981bbab0b4ded4a143b2e1e3c53546bbc5dfe06751dac072b5b61d8

environment is virtualbox.

other:

uname -a
Linux k8s-master-node 3.10.0-1160.el7.x86_64 #1 SMP Mon Oct 19 16:18:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)

I'm sorry for the late reply. What's your expected? Do you want to specify a platform to commit the image?

[huanghantao]

yes, specify the platform to linux/amd64 when commit the image, because I don't want this warning.

You are commting a container, If this container is previously running without platform labels then the commit can't find this label and will set default platform label ( which is the platform that you are running on) . So to avoid this message try to create/run you container with --platform flag
