how to pull from local docker registry and push to local docker registry?

[m986883511]

my local docker registry:

docker run -d --net=host registry:2.8.2

it already have all openstack images in it.

when I research cephadm, it recommend use podman. I push ceph docker image in my docker local registry, but I can not use podman pull it from my docker registry.

I search it in google, found podman can pull image from dockerhub, but how to pull form local docker registry?

@m986883511, thanks for reaching out. It would be helpful if you could share the exact command and output + error you get.

For testing and development, I usually run and use a local registry as follows:

# Start the local registry on port 5000
$ podman run -d -p 5000:5000 registry:2

# Tag a local image
$ podman tag fedora localhost:5000/fedora:latest

# Push the image: notice that --tls-verify=false to avoid the push error
~ $ podman push --tls-verify=false localhost:5000/fedora:latest
