I found this comments in devstack https://github.com/openstack-dev/devstack/blob/master/lib/glance#L180-L181 and I'm trying to reproduce this not implemented behavior, because I want to implement it with CACERT.

# NOTE(dims): Currently the glance_store+swift does not support either an insecure flag # or ability to specify the CACERT. So fallback to http:// url

I installed devstack with the following local.conf file:

[[local|localrc]] ADMIN_PASSWORD=supersecret DATABASE_PASSWORD=$ADMIN_PASSWORD RABBIT_PASSWORD=$ADMIN_PASSWORD SERVICE_PASSWORD=$ADMIN_PASSWORD enable_service tls-proxy enable_service s-proxy s-object s-container s-account SWIFT_REPLICAS=1 SWIFT_HASH=1234123412341234 USE_PYTHON3=True HOST_IP=10.0.2.15

After that I changed http to https in /etc/glance/glance-swift-store.conf for auth_address and restarted g-api service. In the next step I upload an image, but everything working good. Does anybody know how to reproduce it with CACERT ?
