Adding tags to machines

The following command will tag all machines that have as1-maas-node- in the name with asrock01

landscape-api add-tags-to-computers "as1-maas-node-" "asrock01"

Choosing specific hosts and tagging them

landscape-api add-tags-to-computers "title:as1-maas-node-01" OR "title:as1-maas-node-02" OR "title:as1-maas-node-03" asrock01

Searching something with regex, and then adding the correspongding tag

for c in $(landscape-api get-computers --json | jq -r ".[] | select(.title |test(\"^as1\")) |.title")
do
    landscape-api add-tags-to-computers hostname:${c} asrock01
done

If you're using juju, then you might find the following more useful to add tags per AZ

#!/bin/bash

. landscape_rc

juju_machines=$(mktemp)

juju machines > ${juju_machines}

for az in $(cat ${juju_machines} | awk '{print $6}' | tail +2 | sort | uniq)
do
  for host in $(cat ${juju_machines} | grep ${az} | awk '{print $4}')
  do
    landscape-api add-tags-to-computers title:${host} "${az}"
  done
done
