Description Daniel Mach 2018-03-20 07:53:41 UTC 
This is a request to provide subscription-manager YUM4 (DNF) plugin as part of subscription-manager sources in RHEL 7.

The YUM4 software management stack (based on DNF) needs to be able to consume content from CDN. Subscription-manager plugins for YUM4 are not available on RHEL 7 at the moment.

This is related to bz#1533905, but for a different distro.

YUM4 will be most likely shipped in an additional (opt-in) repo rather than part of core RHEL. That's why the python2-dnf-plugin-* sub-packages must NOT land in RHEL 7 repos directly. We could either ship the sub-packages in the additional repo or re-build RHSM from (identical) source with different macros to enable the plugin and then ship it in the additional repo.

Note:Install dnf-plugin-subscription manager and its dependencies from Extras repo.

Since both yum and dnf can co-exist on RHEL76, make sure to disable all yum plugins in order to ensure that system is using dnf and its plugins ..

1.Make sure all the yum plugin are disabled on the system 

# subscription-manager config --list | grep auto_enable
   auto_enable_yum_plugins = 0
2.
# cat /etc/yum/pluginconf.d/search-disabled-repos.conf | grep enabled
enabled=0
# Repositories matching the patterns listed in ignored_repos will not be enabled by the plugin

# cat /etc/yum/pluginconf.d/subscription-manager.conf | grep enabled
enabled=0

# cat /etc/yum/pluginconf.d/product-id.conf | grep enabled
enabled=0

3. Register and auto-attach system 

# subscription-manager register --auto-attach

4.Remove the redhat.repo file from the system 

# rm -rf /etc/yum.repos.d/redhat.repo

5.Verify the repolist and make sure the subscription manager plugins (product-id and subscription-manager) are loaded 

# dnf repolist -d3

User could successfully install a package on system using dnf command. 

Note: A separate bug is logged to track the "Unknown configuration option: ui_repoid_vars = basearch in /etc/yum.repos.d/redhat.repo" Bug 1614649

Conclusion:
Based on the above observation, confirmed that user can now list repos and install packages from repos using dnf command. Moving this bug to verified.
