UPDATE: It turns out that installing the new client can cause issues with Keystone. I found this out the hard way yesterday when it failed during a demo, preventing authentication from the command line. After a few hours troubleshooting it turns out Apache (httpd.service) and Keystone (openstack-keystone.service) were clashing. I was unable to fix this regardless of updating each of these services config files to separate them out. Finally guessed it might be the last package I installed that was the cause. After removing python-openstackclient and rebooting the controller node the issue was fixed.

Original post
===============
In OpenStack Kilo the Depreciation message for the Keystone CLI will be displayed whenever using invoking the keystone command. “

DeprecationWarning: The keystone CLI is deprecated in favor of python-openstackclient. For a Python library, continue using python-keystoneclient.

”

To move to the new python-openstackclient, simply install it. On RHEL7.1:

yum install -y python-openstackclient.noarch

After that it will be available as the command “openstack”. It can be invoked in interactive mode just by typing “openstack” or directly from the command line to get information. For example, to list users:
Old Keystone CLI: “

keystone user-list

”
New Openstack CLI: “

openstack user list

”

To be more similar to the output of the old command issue “

openstack user list --long

” to get the extra fields.

You may also want to update the script “openstack-status” so it uses the new client. To do so, please:
1. Edit

/usr/bin/openstack-status

with your favorite editor
2. Replace the old command with the new one (around line 227) like so:

#keystone user-list
openstack user list --long

The new CLI can do a lot more of course. For a full list of commands please refer to the below (executed with “openstack” + command):

Currently installing a few C6320 servers with RHEL7.1 to create an OpenStack demo cluster. Since all servers need almost identical setups I wrote some Expect scripts but unfortunately didn’t put the script runtime timeout high enough. This resulted in the connection to one of the servers being interrupted in the middle of a “yum update -y”.

When trying to run the update again it failed with: “[Errno -1] Package does not match intended download. Suggestion: run yum –enablerepo=rhel-7-server-rpms clean metadata” “Trying other mirror.”

Unfortunately, running the suggested “clean metadata” didn’t fix the problem. Instead, the fix turned out to be a simple “yum clean all” 🙂
