Ansible group

i'm trying automate deployment of sensu checks each role host plays.

i have structure

group_vars/   nginx

in each group_vars file, have defined following:

sensu_checks:   - check_name   - check_other_name

so example, in group_vars/all i'd have:

sensu_checks:   - check_raid   - check_load   - check_disk

in group_vars/nginx i'd have:

sensu_checks:  - check_pid  - check_http

what know if it's possible checks specific host should install, example with:

- name: print host sensu checks   command: echo {{item}}   with_flattened:    - {{ sensu_checks }}

this doesn't work though, gives me group_vars of last group host name defined in. there way flattened list checks of groups host attached to?

in previous example, i'd expect

 [ check_load, check_disk, check_raid, check_http, check_pid ]

but instead i'm getting

[ check_http, check_pid ]

for nginx host (which part of both 'all' , and 'nginx' groups)

with_flattened doesn't expect in case - you're victim of variable scoping.

the nginx group specific, ansible using variable definition - explains why you're getting sensu_check defined in nginx.

you rename var in 1 of 2 places (i recommend nginx var, since that's specific one), , use with_flattened combine 2 lists:

with_flattened: - {{ sensu_checks }} - {{ sensu_nginx_checks }}
