MAAS equivalent of xcat groups for bulk commands?

Docs
1

We’re working on replacing an old xcat installation with MAAS. One thing that’s very handy in xcat is the ability to run commands on groups of nodes. E.g. if I have a group named grp with 100 nodes named grp001-grn100 in it, I can do things like:

rpower grp boot # Reboot all the nodes
rinstall grp # Reinstall all the nodes
psh grp touch /tmp/foo # SSH into all the nodes and touch /tmp/foo

I’m guessing that MAAS has something like that, maybe with tags or availability zones or pools, but so far I haven’t found any example commands in the docs or discussions. Could anyone post an example or point me in the direction of the correct docs?

Thanks.

After playing a bit more, the nicest version I can think of that kinda fits with the design of MAAS would be a way to specify a filter instead of a tag.

E.g. in addition to this:

maas admin interface update 48flss eno16 vlan=101

…you could also do this:

maas admin interface update --tag=dell_7960 eno16 vlan=101

…or:

maas admin interface update ‘{pool: “us-east-workers”, .link_connected: true}’ vlan=101

I’m not sure if those are the best possible ways to do it, but something like that would be a handy sort of thing to have. So far I’ve been doing the equivalent with big ugly command lines involving maas, jq, awk, feeding back into maas again.
