Hosts inventory¶
While running playlabs with @hostname
arguments is nice to experiment with,
it won’t scale with many machines nor will be convenient to automate playlabs
calls. Most roles require an inventory to be really fun.
Pre-requisite¶
Clone the inventory repository that you have been given if any. If it doesn’t work, make sure that the git server knows your ssh public key if authenticating with SSH.
If you haven’t been given an inventory repository to clone, create one with the scaffolt command (note that you can have as many inventories as you want):
playlabs scaffold your-inventory
Adding a new host¶
Hosts are defined in the inventory.yml
file of the inventory repository,
use the all
variable to add them in no specific group:
all:
hosts:
yourhost.com: # adds a host with no extra option
otherhost:
fqdn: yourdomain.tld
ansible_port: 22
ansible_host: 123.12.12.23
Setting host groups¶
You can link hosts to groups in the children
variable of the
inventory.yml
YAML document. For example, if you want playlabs install
ssh,netdata
without argument (for CI likely) to apply on otherhost
, then
this will work:
children:
netdata-ssh:
hosts:
otherhost
