Dynamic Inventory

[gvenka008c]

@sttts I was looking at your mesos repo [compute-platform/roles/mesos/tasks/]. How do you build your inventory? Are you using the dynamic inventory? Do you have any script that constructs your inventory file dynamically?

Thanks, Govind

[sttts]

I just have a static file with one line per host (with the IPs) and a list of hosts per role.

@sttts Thanks.

@sttts so is this script run against the static inventory file?

zk:// {%- for host in groups['mesos_masters'] -%} {{ hostvars[host]['private_ip'] }}:2181{% if not loop.last %},{% endif %} {%- endfor -%} /mesos

[gvenka008c]

@sttts I got the error as below when using the code zk:// {%- for host in groups['mesos_masters'] -%} {{ hostvars[host]['private_ip'] }}:2181{% if not loop.last %},{% endif %} {%- endfor -%} /mesos
