Hi All. Here are some interesting one-liners I’ve used. Hope they help!<\/p>\n
And by “one-liner”, of course, I mean “a bunch of commands all typed on one line” \ud83d\ude42<\/p>\n
All one-liners assume you have sourced in your RC file so that OS_XXX environment variables are set correctly:<\/p>\n
Here’s a nice little gnarly expression:<\/p>\n
\r\nfor j in $(openstack project list -c ID | tail -n +4 | head -n -1 | awk -F'|' '{print $2}'); do _s=$(openstack --os-project-id $j server list | grep '| \\+ACTIVE \\+|' 2>\/dev\/null | sed -e 's# ##g'); [ ! -z \"$_s\" ] && (_n=$(openstack project show $j -c name | grep -e '| \\+name \\+|' | awk -F'|' '{print $3}' | sed -e 's#^ \\+##' -e 's# \\+$##'); echo \"Project $_n ($j)\"; openstack --os-project-id $j server list | grep '| \\+ACTIVE \\+|'); sleep 1; done\r\n<\/code><\/pre>\nExplanation? Iterate over all projects; for each one do a quick server list looking for ACTIVE VMs. Run the result through a sed<\/code> to eliminate whitespace; if there is anything left, we have active servers \ud83d\ude42 We then do a quick lookup on the project ID to get the name (with appropriate calls to trim spaces) and show the project name, ID, and list of active VMs.<\/p>\nWant some output?<\/p>\n

List permissions for a given user across all projects<\/h3>\n
Here’s the one from today. I am migrating to OpenStack Kilo from Icehouse and I want to kick some of my old users off of the original Icehouse deployment. Keeps ’em from messing things up!! So to do this here’s my line-liner:<\/p>\n
\r\nfor i in $(openstack user list -c ID -c Name | grep \"| [USER]<\/strong>\" | awk -F'|' '{print $2}'); do l_printed=0; for j in $(openstack project list -c ID | tail -n +4 | head -n -1 | awk -F'|' '{print $2}'); do l_roles=$(openstack user role list --project $j $i); [ \"x$l_roles\" != \"x\" ] && ( [ \"$l_printed\" -eq 0 ] && l_printed=1 && echo \"Project: $j\" && echo \"User: $i\"; openstack user role list --project $j $i; ) done; done\r\n<\/code><\/pre>\n
