i have an requirement to pass paramaters to the node-id based on the number of hosts present in the host inventory
Considering we have 3 hosts , the parameter with node-is gets built as below
how can we achieve the same dynamically based on the host inventory ?

An option would be to use "set_fact" and prepare the command. Start with the common variables
- set_fact:
my_command: "init-cluster -cluster-name lbcluster -dbname dbname
-dbtype postgresql -dbhost dbhost -dbport dbport
-dbuser dbuser -dbpass dbpass -zk-servers zk-servers
-storage-strategy storage-strategy
-storage-hdfs-uri hdfs:// hdfs-namenode :8020
-storage-hdfs-root /root
-overwrite"
and loop "groups.all" (fit the list to your needs).
- set_fact:
my_command: " my_command + ' -node-id ' + item "
loop: " groups.all "
- debug:
var: my_command
- command: " my_command "
